Angie's List asked three Cincinnati experts for advice, trends and what not to do when building a storage shed.

What are some recent trends in storage structures?

Moore: Small or medium sized sheds to store garden equipment. Homeowners like to make the structure part of their backyard landscape, adding windows, flower boxes and bushes.

Peters: Homeowners try to match the structure with their house to make it look like it belongs there. I can build detached garages, sheds or barns, depending on the size of the lot.

Feist: Homeowners want textured sheds with window boxes and shutters that match their house. For garages, they prefer extra storage in an attic area with a fold-down ladder.

What is the best season for building storage and garden sheds?

Moore: If your building requires a concrete floor, temperatures must be above freezing. You'll find the best deals in the cooler months when contractors' schedules aren't filled.

Peters: There's never a bad time. I work through the winter if I have access.

Feist: The spring is the best time to get started, but you'll get the best pricing in the winter.

What can homeowners do to maintain the appearance of their shed?

Moore: Caulk and repaint the siding every couple of years. The best structures will have concrete floors and vinyl siding, which will save you money and time in the long run. Wood siding will rot.

Peters: It depends on the materials. I recommend washing vinyl siding annually, re-caulking every fall and repainting every 3-5 years. Spend the extra money on a 30-year roof and vinyl or brick siding. Avoid wood, because it will require maintenance every six years, and the siding will need to be repainted. On soffits, siding and gutter boards, wrap everything in aluminum to avoid having to paint it.

What else should homeowners consider before building a storage shed?

Moore: Ask your contractor about materials and how it will be constructed. If you wouldn't use particle board to side your house, then you shouldn't use it on your shed.

Peters: The first thing you should do is evaluate what you need the space for in order to determine what size and style you'll need.
