Does it matter if a roofer hand nails or uses a nail gun?

The most important thing you can do is choose a roofing contractor who has a proven track record, will clearly explain his or her method for nailing in writing and will offer a comprehensive warranty for their work and will stand behind the warranty should something go wrong.

Dear Angie: My home needs a new roof. Which is better: hand nailing or using a nail gun for the roof shingles? Does it matter? – S. A., Norman, Okla.

Dear S.A.: Let me start by answering your last question first. Technically, it does not matter if a roofer hand or gun nails the shingles. Both methods are approved by roof manufacturers, so there is no “right” or “wrong” way.

That said, this is certainly a topic about which many roofers are very passionate. Improperly nailed roofs can be more susceptible to leaks and damage from storms. Ideal nail placement on roof shingles is limited to a very small area. If the nail is driven outside that area, it could impair the roof and void the manufacturer’s warranty.

Because of that, many highly rated roofers on Angie’s List tell me their preferred method is to hand nail roofs. By hand-nailing the roof, roofers can ensure the nail is properly placed and is nailed in at the correct depth; flush with the shingle and not over- or under-driven.

Though this can be achieved with nail guns, many roofers tell me there is more room for error; especially if the person doing the nailing is inexperienced or is rushing through the job.

Contractors who nail by hand say they can feel whether or not the nail catches the wood, but don’t get that same feeling with a nail gun. Nails driven between boards or outside the ideal placement area will loosen over time, eventually causing raised shingles or leakage. If there is a failure with the roof and you make a warranty claim, expect the manufacturer to check the nail pattern to ensure the nails are flush and placed properly.

The advantage to nail guns is that they do reduce the amount of time and require less effort to put on a roof. As one roofer told me, a nail gun never tires, unlike a worker who’s been hand nailing on a roof all day, it’s 3 p.m. and 100 degrees on the roof.

Still, there are a lot more variables to gun nailing. It is important the nail gun compressor settings be adjusted regularly and the equipment is properly maintained. To account for variations in temperature, wood type and roof type, the air pressure for nail guns must be adjusted frequently and accordingly. The angle of how the roofer holds the gun is also important. If they’re off, even slightly, the nail can go in crooked.

The bottom line is both methods have their flaws. The most important thing you can do is choose a roofing contractor who has a proven track record, will clearly explain his or her method for nailing in writing and will offer a comprehensive warranty for their work and will stand behind the warranty should something go wrong.

I'm 52 and my crew hand nails. The roofers that use guns don't want to pay there dues and learn this trade -. Get a gun gun now ur as fast as usas long as u use guns we will always. Have a roof to go fix

I Know this is dated 2013 , but couldn't resist ....To many contractors the faster the better ... But haste makes waste.....Shortcuts cause problems...did you ever see a roof torn off after a windstorm on one house and not on any of the others ? Look closely and you will see where two or three guys had nailed the roof in sections looking like zippers straight up and down the each other to get the job done . They don't care what the pressure setting is on the gun or even if they hit the sweet spot. And half the time none of them knows how to properly nail a valley or install flashing around a chimney. ask them about a cricket and they say "never saw one B4" . I fired a roofer who claimed that bent flashing was as good as a fabricated drip edge because he said " I've been roofing for 40 years" I said you've been doing it wrong for 40 years too ! The contracts spec's are what counts AND the quality of the contractor that will follow them is most important.

The angle at which the nail is placed is also very important. Often with nail guns the nail is not angled properly allowing the nail head to tear the shingle. I find that with handcrafted you will always end up with a better product. If you can find a contractor willing to hand nail at a price point that fits your budget go with hand nailing. If a pneumatic guns are used make sure you trust who is supervising the installation.

I have been a carpenter and general contractor for 35 yrs. Nailing with a gun or hand makes no difference as long as the manufacturers specs are observed. If you are a roofing contractor today you are not hand nailing. Remodelers may roof by hand because they are not willing to invest in the equipment. Mainly because they do not roof everyday. We are talking nails, hand or gun. Staples are the method used years ago that gave machine roofing a bad name. Make no mistake, we are in business to make money. Hand naming will not do it. Also this crap about 1x6 boards, reroofs on most board roofs need to be replaced with 4x8 sheathing. Another point is roofing nails do not have the barbs and do back out"......

I've been a contractor since before roofing guns were used. If you were brought up hand nailing you can keep up a pretty good pace. I know of two roofing contractors in my area, North of Boston, that only hand nail. They'll come down with about 8-10 guys and finish most roofs in a day, hand nailing. If you have guys that know what their doing you can get the job done, and nailed better than a roofing gun does. I don't know how many roofs I've looked at where nails are in crooked and have melted through the roof. I do use a roofing gun from time to time, but I also carry my hammer to whack any nails that go in crooked, my wrists are not what they used to be, more so from nailing fir decking down with 8P finish nails I would think and framing whole houses by hand before we started using framing guns too. LOL

just a note from the 5th generation of hand-nailers.

im glad i live in colorado,, we never use shingles here in the mountains,, the only roofs in this county are pro-panel roofs , metal,, they never leak,, last 40 years, and the sno slides easy so the load dosent build up,, ,, id never do shingles again,, ever

been roofing for many years and cannot imagine doing so without a gun. a square or two or bet. hand nail 10-14 squares in a day? good luck with that. get a good cleat on an under-stack in tight quarters? good luck with that. never had a call back, never had a leak, never heard so many dopes issue opinions with no experience to back them up. reading popular mechanics does not make you a tradesman. many of the new shingles have expanded nail even us stoopid roofing contractors can get it right for all you homeowner experts and handymen

I agree, you either know how to roof or you don't. I can hand bang or use a gun. I have noticed that both methods work exactly the same granted the installer knows how to adjust the nial depth on the gun. Its the future, and engineers have innovated nial guns through simple physics to make roofing more practical, nial guns are just faster and can produce the same quality if the worker knows what he is doing.

I couldn't have said it better!

I have seen testing on this subject and they said a staple gun used perpendicular to the ridge held shingles the best. Better than nailing the shingles.

don't listen to that guy 80 dollar harbor freight guns work just fine,sure if your a contractor you would have better more commercial tools but for the occasional do it your selfer cheaper tools work just fine, and I believe that was who asked the question.

And just to add, all my work is in north upstate NY. 100-200" of snow and the qualified guys here stand out as they all recommend new substrate where issues exist. Anything that is load bearing needs 3/4" sheath. CDX is fine. The other great point is that a "Pro" spends their time on transitions, valleys, step flashing prep before they shingle. Put a good quality regulator on air to a decent gun, give it 2 drops of 10 weight pneumatic oil every couple square (or put an in-line lubricator after filter-regulator better yet) and a gun is the way to go as long as you keep hose in front of you to avoid tripping on it as you work your way down.

OK, I've read enough. I'm a double-degreeEngineer. I worked my way through college 30 years ago as, yes you guessed it, a contractor. Probably 50 more roofs since then. Professional areas of expertise: hydraulics, pneumatics, automation and chemicals/elastomers (can we all say shingles, rubber and sealants). The issue with quality guns is setting/maintaining air pressure, light but periodic lubrication of air and proper placement. The typical idiot using an $80 harbor freight special, is cranking pressure to eliminate misfires and partial sets. Once they learn to lubricate it, these units have oil poured into them until they ooze through bad seals in the nose causing 'wet nailing' and dark spots. Oil is an aromatic and will cause deterioration to shingles, sealants and non-permeable underlayment. I can hit my mark as easily with a quality gun as hand nailing. Of course with my roofing hatchet and urethane (not silicone) sealant in my holster in case I hit an underlay fastener. Why anyone would nail fresh material onto a substrate with 'soft sports' defies logic. I see a greater chance for overdriving on a sound sheath by hand as human error with a standard 2 hit drive (start nail on one and drive with second). Show me someone that taps a roof nail with 4-5 taps, and I'll show you a rookie. Sorry, but I don't think half the comments here speak from any professional experience, unless they like to do hard labor in a hot sun for a fraction of the pay and a double helping of the pain. I've had the same conversation with a younger buddy of mine who started a no investment framing gig. I buried his day's work in 5 hrs with my Duofast without breaking a sweat. He bought my gun and pancake compressor before the day's end, and I upgraded for free!

Sorry guys but you're fighting a losing non-sensical battle with this hand nailing crap. Its like saying, " they just don't do it like the old days". C'mon son! Go buy a model -T , start churning butter on the farm and making beer in your bathtub while you're at it hand nailing roofs. Makes about as much sense. Any roofer with any kind of skill can use a nail gun and properly place a nail in the nailing hem without much issue. This is not rocket science. If a nail doesn't seat pound it in, if it misses put another nail a few inches away and your fine. Again the tar strip along the bottom of the shingles are redundant. As long as you follow installation instructions you're good, as the manufacturer is the final say on warranty and installation issues.

It also depends on the roof material, plywood or sheathing hold up well to air nailers. My home is completely roofed with 3/4" x 10" tongue and groove. Last year, my contractor opted to do by hand, he said that air nailers can punch through sections of lap board or tongue and groove due to the variances in different boards.

Over the years, I have had many old roofs redone by contractors. I have always had a complete "tear-off" and "re-decking" with either plywood or "Blandex" placed over the original roof boards. To me, what is critical is the quality of the shingle used, the placement of rubberized sheeting on top of the decking near the lower edge to prevent "ice damning" from causing water back-up leaks, and the quality of all "flashing" and "valley work". With a new decking surface, the shingle nailing will be uniform and therefore "gun nailing" is perfectly fine (as long as the nails are properly located). One annoying thing I have noticed with contractors is that they don't like to remove the plastic strip covering the seal-down strip on the back of the shingle. They say it doesn't matter. That may be true since I have had no problems. But, in a high wind area, I would make sure the contractor removes the plastic strip so that the seal-down strip will make good contact with the shingle below it. If the seal-down strip sticks to the shingle below it, I would see no need for any special "wind-nailing",

I am concerned with the ADVICE people are giving here, The plastic strip is not so the roof sticks to each other. IT SHOULD NOT BE REMOVED. It is simply put there to line up with the adhesive that does make the shingle stick to each other. True shingles have adhesive but the would stick to eachother during shipping so each has a plastic strip to prevent them from stici

If the plastic protective strip is never to be removed what is the purpose of the adhesive to begin with? My house has a 12/12 roof that has lost shingles since week one of installation. The roof has had a continuous leak somewhere for the extent of the 30 year warranty. The roofer said the plastic strips had to remain(warranty) in place which allowed the shingles to break and lift off with regular winds. The roofer made annual repairs but the water damage was accumulative and the ceilings and flooring had to be repaired at my expense. I used 20 year shingles on my garage roof and peeled off the plastic strips. It has never leaked a drop and every shingle looks like it did 40 years ago.

I agree with except for the plastic removal part, follow manufacturer installation instructions and you'll be fine, "wind nailing" is required to get the lifetime warranty, which consists of adding 5 nails in the nailing field instead of 4. You'll notice as you apply the shingles that the installation is redundant with each shingle overlapping the next, so you end up with 10 nails in each shingle.

I started roofing in 1965 with hand nails (2 - 3 sqs an hour). I have been a contractor for the last 20 years and currently roof 150 to 200 homes a year. All of our crews use nail guns. To find a "professional" that hand nails is unlikely. To even purchase a 50 lb box of hand nails from our supplier (a national roofing supply house) is by special order. Young workers today are not taught to hand nail ... there is no one to teach them. To say we should hand nail instead of using guns because it is better is simply not realistic. We need to train our workers to install good roofs with guns. They should have a hatchet with them at all times to drive a nail that is not flush. Good roofers will always put the nails in the "nail strip", gun or not. I have several men that know how to hand nail, they are in their 50's and work for me as inspectors. That is the key to a good roof. A contractor that inspects the work when it is done to make sure of the nailing, and especially all the flashings. The bottom line is guns are here to stay and you need someone who is properly trained to use them. When I am sitting at their kitchen table and my bid to put their roof on is 10% to 20% higher because I am using hand nailers, 99.9% of homeowners are not going to sign with me. Economics

Careful workmanship is de rigeur, with or without power nailing. I have done it (I am a retired contractor) both ways, prefer power nailing -- the compressor can be set to bed every nail perfectly and most roofs are sheathed with plywood which makes hitting an open joint rare. I would rather see some of the high-tech products like the stick-on underlayment employed and careful attention to flashings.

In New England, most house roofs have growing black stains--caused, I am told, by nail guns. Horrible looking, and prevalent.

The black spots are caused by algae growth and have absolutely nothing to do with nail guns. This can easily be washed with a chlorine solution. New shingles have a copper additive to the grit recipe, and most have a 10 year warranty against this growth.

Everyone thinks they are a professional until they really meet one. And the most important one of all is : Amatuers teach ameteurs to be amatuers. Gun nailing is just what it is, a way to go faster with out the ability to "feel" the substrate reacting. There will never be a better way for a person to communicate with the nail other than by hand. This is not debateable!

It is true that "there is no better way to communicate with a nail" by hand nailing. But so what? Machine nailing does just as good a job and often better because it is consistent and doesn't get tired. it's the same thing like robotics taking over many jobs in the auto manufacturing industry. Seems to me many nailers have an ego complex in this regard.

Thanks for the laugh. As someone who builds houses for the country's largest homebuilder, I can say I've never seen a roof hand-nailed for them. In our region, they build 40-60 houses a month and they are not hand nailed. I guess those "non-professionals" who shingle 500+ houses a year are just amateurs.

Mr. Brown, you just made his point. All you do is mass manufacturing of junk houses that couldn't stand past 20-30 years. Just like making a car, there are a myriad of ways to do it, and in the end you end up with a cheap car or a hand built car that lasts the ages. Mass manufacturing of houses has made it easy and cheap for people to buy, but that does not mean it was built to last like the homes that were built decades ago. I know, because I live in a vinyl village home because that is what I could afford (C.P. Morgan), and the house was built by illegals in record time and I doubt it makes it through my mortgage before it falls apart. THE ROOFS ON THESE HOMES IN MY AREA ARE BEING REPLACE ALMOST MONTHLY FOR FAILURE AND THE "VILLAGE" ISN'T EVEN 15 YEARS OLD YET. Junk materials and installation. Period.

don't pick the hammer or the gun, pick the contractor

Good arguments for both methods. But, can't it be too hot for roofing. The softer shingles could be damaged more easily when the temperature is extremely hot.

Owned my residential roofing company in South Georgia for 25 years. Have been in the roofing business over 44 years. A couple of observations above are correct. Shingle manufacturers don't care whether you hand nail or gun nail. They do care that you nail the correct amount of nails for each shingle and in the right spot. An old roofer saying is, "Anybody can lay shingles in the field of the roof, it's the valleys, chimneys, pipes, eaves, rakes, ridges, and valleys that make you a roofer." Find one with references who is a master at these areas you don't have to worry about the field. Hand vs. gun. Guns make roofers faster, but not better. There is only a small strip in the middle of the shingle for the nails to properly go. Going faster gives you more opportunity to miss the strip or accidently hit the gun on the wrong part of the shingle and it will fire anyway shooting a nail Now someone will say that's why the gun has the safety feature. Mash the safety on the shingle and pull the trigger to shoot the nail. They all know that's not true, because it only makes you slower, not faster. You hold the trigger down all the time and hit the shingle with the gun. It fires immediately. Been there, seen that. Correct pressure is another problem with nail guns. You keep the pressure the same the gun will shoot with the same pressure every time. Pressure yes, depth no. Lets say you adjust the pressure and test the gun in the middle of a piece of decking. Shoots fine, but then you come to a rafter and find you don't have enough pressure to seat the nail. Use your hammer and knock it down. Or vice versa, you test on the rafter fine, but then shoot the nail completely through the shingle between the rafters. New younger roofers use nail guns. Older roofers know hand nailing is slower but better. Of course, back in the day I wasn't much slower than a nail gun by hand. Could hand nail about three squares per hour if someone laid them out for me. If you don't have enough pressure with the first hit, you hit it again. You our always placing the nail with one hand and hitting with the other so hard to put the nail in the wrong place if you know where to put the nails. Hand nailing also allows you to know immediately whether you hit the decking or missed. And one roofer above is definitely correct. You hand nail zinc coated barbed nails and they will never pull out. Ever. they will never rust either. Remember, ask for 5-15 references with all roofs being over 5 years installed. Call them all, and if you can go look at 3 projects personally do. Either way of nailing, you get a reliable contactor, you will get a good job.

There are lots of pretenders here. Virtually all roofing contractors use nail guns anymore. Anyone who shows up with nothing but a hammer, just hasn't done enough jobs to be able to afford a compressor yet.

As a professional roofing company with tens of thousands of roofs installed, we only hand nail. No callbacks or issues with high-nailing, crooked nails, under driven or over driven nails. We use American made ring shanked, zinc iron oxide double dipped Maze nails that cost a little more, but don't have issues with rusting like the cheap imported nails which are poorly made for the pneumatic nail guns. We don't tear up the undersides of the decking like pneumatic nailers do. Our crews are professionally trained and know and appreciate a job well done. We don't drop oil on the shingles or drag hoses all over the roof. We don't trip our client's breakers or use their utilities. Hammers don't have as large of a carbon footprint as the pneumatic nail guns, but are just as fast. There is no setup time, no equipment repairs or maintenance, and we do know when the nail is properly seated.

We have an older home (1912) with the original wide plank boards. A roofer used a nail gun and we subsequently lost many shingles because 1) some nails went into the spaces between the boards; and 2) the force of the nail gun caused a lot of the old, dry boards to split, especially when nailed close to an edge. In the future, we will always insist on hand nailing.

The problem with your roof is that you didn't plywood over the existing boards before installing the new shingles...not the method of nailing. Old roof boards that are cracked, split, rotted or just soft won't hold ANY nail properly regardless of how it's driven. In older homes, there are times when replacing the roofing is best done by replacing the roof substrate FIRST because the framing members simply won't take the weight of an additional layer of plywood. More often than not, how poorly a roofing job is completed is related to the owner's budget.

i have been roofing for over 25 years hand nailing is the most safest for the consumer.when using air guns every body has a tendency to try to be faster not careful about placing nails where warranteed the roofing industry should have inspections gun nailing can be done on plywood,osb, but not on 1x6 roof sheathing or on boards most people do not know when they hit a crack that allows the sun to back the nail out we should try to raise a standard not just get the job done

"After he left, I bought 50lbs of the sealing roofing nails and went over every shingle again wind nailing them, we have not lost a shingle since. "How did you accomplish that??? Once the roof is installed,

I prefer hand nailing, the nail heads are much larger and hold better. I wind nailed all the roofs i recovered, when i used to live in Cleveland Ohio. I was never licensed, i worked for friends and family and people who acted as their own contractor. I was a journeyman Carpenter. Wind nailing is nailing the exposed tabs on the shingles with a galvanized roofing nail with a rubber gasket under the head. This type of nailing is slower and more expensive, but is the best you can get. I lost all the shingles twice in our current home here in California, the contractors used guns with staples. I told the last one to wind nail and he looked at me as though I was crazy. "What the hell is that" he asked. After he left, I bought 50lbs of the sealing roofing nails and went over every shingle again wind nailing them, we have not lost a shingle since. Even though we get 60 to 80 mph winds every year. I grew up in a family full of craftsmen and contractors.

We had a similar experience in Alaska. Insurance company did 'normal' roof repair. After we lost the roof again, we not only 'wind nailed' each one, we applied silicone seal over each nail. no more lost shingles!

Wind nailing, is two nails in each tab instead of on nail. Rubber gasket nails are used for corrugated steel roofs.

I am an experienced roofer. Use the gun for the shingles and it must be a quality air nailer. Hand nail the sheats underneath the shingles. Quality of the job is dependent on the condition of the sheets and how a roofer seals around rakes, chimneys etc.

I Live in Texas and we were told we need a hurricane /wind proof roof and we needed to hire a contractor that hand nailed the nails and we did that but with all the new contstrucion after IKE around me I here other homes around us not using hand nails and using guns for there roof and my question is has anything changed since we had our done right after the storm till now. I still live in a area that we have to have wind and storm insurance. Has any changes to the building codes changed for my area or any area that is prone to Hurricane activity.

A gun nailed roof, properly installed, That's the key phrase: properly installed. A good many roofers use a gun so they can dial it up so they can shoot faster and get done faster. Speed over everything else. Hand nailing is only one speed. That's why hand nailed roofs fail less than gun nailed..

15 years of roofing and I have never been called back to fix a problem on any house that I gun nailed! But I have had a lot of word of mouth referrals passed my way from the fast and correct roofing jobs that I have done (all with a nail gun). The old way of hand nailing is dangerous because if you drop nails you can't find them all. But if I drop a roll of (nail gun) nails I can find it easily. More safety for family's with kids that play around the house. Ps are air hoses have shut off protection so if a line gets cut it won't swing around like a snake. So if you dont have a nail gun, spend some $ and learn how to use it and you will never want to hand nail again.

I have roofed houses in upstate N.Y. ,Fla. ,and now live in Ga. I have roofed many house 's and commercial buildings over the years with no advertisement except word of mouth and stayed very busy. I agree both methods have their problems if not DONE RIGHT. I have trained many people over the years to roof the right way. you can lead a horse to water but you can't make it drink. people fail at times and so do the equipment.we have some good days and some bad.but a good roofer will gurantee his work when he comes back if a problem occurs and fixes it with no extra cost. roofers in general do some things a little different from others because thats what their good at. nail guns are not the only problems for a good have flashing along walls,chimneys,valleys. you have the right application in starting and finishing the roof. also any repairs of the decking.also seal anything that need to be. also clean up of the yard very important with kids pets,lawn mowers. so their is a lot more than most people realize. but bottom line is to find a good roofer that's been refered to you with a good report in the community.remember higher prices is not always a better job. I hope this input may help someone to make a wise decision.

The article was clearly NOT written by someone with roofing experience. There is a HUGE difference between hand nailing a roof and gun nailing it. Anyone who has actually seen a compressor and a nail gun can figure out how to adjust the air pressure, and the guns depth setting to get the nails right. It isn't difficult. But what is difficult is keeping the slick sided hand nails from backing out of the roof decking! Gun nails have a couple ridges in them from the wire collation. That keeps the gun nails from backing out of the wood. NOTHING keeps hand nails from backing out. A gun nailed roof, properly installed, is a better roof than a hand nailed roof. Period. Anyone that disagrees, please present your theories. I'll be more than happy to present the reality of the situation.

Hand Nailing is superior for all the reasons Angie mentioned. Steven Stanley's comment on ridges in gun nails (collation barbs) is mute. Hand nail your shingles with hot dipped "ring shank" nails. They won't back out plus you get all the other merits of hand nailing mentioned by Angie.

I am a handyman and repair damaged roofs from time to time. I have found that air nailers really cannot be adjusted for the various nail beds into which they are driven. Yes, if properly adjusted "most" nails will be OK. However, there are places in plywood and lumber that are harder and this results in a nail that is not driven all the way in unless the roofer notices it and hits it with a hammer. Considering the aforementioned, I have found that some roofers use too much air pressure and this causes the nails to be driven through the shingle and at times both shingles(they overlap in a manner that the lower nail catches the top of shingle beneath it). This will result in shingles being blown up or off in a high wind and if wind drives the rain up under a shingle nailed like that it can cause leakage, too. I recommend that a roof be nailed by hand by a conscientious roofer to be done right.

Now I can tell a few people on here actually know what they are talking about, I have been a journeymen roofer since my teens, father and uncle both owned roofing companies, I am also a journeymen carpenter, so I know how to hand bang, as for the nail not hitting the sheathing, anyone who knows how to use a gun can hear and feel if that happens, as for the depth "flush nailer" adjustment will be different depending on the shingle and the temperature outside, and all composition shingles should be at least 5 nailed, ask your roofer to hand bang 1 shingle and gun nail 1 shingle and try to pull each off, if done correctly, not going to be a difference, alot of old timers want their roofs hand nailed, no problem! Just takes extra time, as for shingles blowing off, that has nothing to do with the plastic strip or if it was hand or gun nailed, that is just poor craftsmanship, couldn't tell exactly what caused it unless I seen it in person. There are alot of roofers who "Blow and Go", not worried if a nail blew through or didn't get sunk flush, happens with gun nailing and hand nailing as well. Your roof is only going to be as good as the person laying it and the material being used. Guns alow the job to get done faster, that being said saving the customer money. If you hire a roofer or contractor that doesn't have air tools, I can pretty much guarantee they are "hacks", it is just not economically reasonable to slow a job down, Im not saying rush through it but why don't you use a hand saw instead of a skilsaw? Because it takes to long and there is more room for error. Also, the tool being it a hammer, hatchet, nail gun or saw is only going to perform as good as the person operating it. There are way more important things to worry about when it comes to your roof being layed, like a few others have said, valleys, hips, flashings, underlayment, and even dormers and vents. There will always be people who take shortcuts and cut corners, hiring a professional who takes pride in their work should be the concern, weather they drove a Ford or Chevy to the job should make no difference, thats how I see hand vs gun, as long as the end result is quality work up to code it makes no difference, knowing what I know though, I would want my roof gun nailed. Anyone that thinks hand nailing is "better", well do the test and see for yourself. As for staples, can't use them here in Cali anymore. Oh ya, for example, anyone who has ever had to pull up shingles that have been gun nailed know what a pain it can be. Like I said, test it out and see for yourself. First thing I would highly recommend a contractor or a journeymen over a handyman, a journeymen has years of hands on experience in the specific trade, and only hire someone who is bonded and insured to roof, if not you could be in for a big headache when winter rolls around and you find out that a valley or flashing has been installed wrong!!

Are you serious? If you can't figure out how to operate something as simple as an air compressor to regulate the pressure, you should not be entrusted with peoples' homes. From small electric compressors to large gas compressors...they ALL can have their pressure regulated by merely turning a dial on the regulator. Additionally, I've seen some roofers put in-line regulators on the guns themselves to actually regulate the air pressure AT THE GUN. Your comment is ridiculous.
