Though heavy snowfall is rare in Los Angeles, it’s important to consider protecting your roof for winter and the inevitable colder weather. Now is the time to consider the use of a waterproof coating for your roof.

Our roofs take the day-to-day brunt of the worst weather conditions, which can lead to the breakdown of roofing materials. According to the Roof Coatings Manufacturers Association, a low-slope black asphalt roof can reach a scorching 170 degrees Fahrenheit at its hottest and 20 degrees below zero in the northern regions.

In areas that reach warmer temperatures, the blackness of the asphalt or tar absorbs the heat from the sun. That heat often makes homes feel warmer and may cause residents to use more power to cool the area.

In addition, ultraviolet rays beating on the outer layers of the roof hasten oxidation and the chemical breakdown of the roofing materials, causing them to become brittle. Unfortunately, our roofs are subject to erosion, expansion and contraction because of the over exposure to the elements, including rain, snow and hail.

A protective moisture and vapor barrier applied to a conventional roofing system can extend its life and improve the energy efficiency of your home by inhibiting the entry of water and creating a lighter-colored surface that reflects the heat of the sun away from the building.

Many barriers can be applied to tar, concrete or rubber-based roofing systems and are a necessity for flat roof lines. Some coatings are also recommended for those who live in mobile homes or have recreational vehicles.

Water-based or agricultural oil-based waterproof coatings – many of which are environmentally friendly, non-toxic, and free of VOCs – first require a layer of specially formulated primer. Some products can provide the necessary seal in one coat while others require up to five.
