Extending the Life of Your Roof

by: Jim Stewart

Heat Damaged Roof Shown is an example of how excessive attic heat can cause shingle granules to shough off, exposing the grain of the shingle to damaging UV rays.

The most important thing you can do to extend the life of your roof is to prevent heat build up in the attic. Heat radiating from the attic softens the asphalt base of the shingle, causing granules to slough off. Granular loss is the most common reason for shortened lifespan of a roof. More detailed information may be found at Proper Attic Ventilation on this site.

Another proactive measure is to keep debris from accumulating in valleys. At least twice a year (more if your roof receives heavy tree leaf accumulation) you should sweep or blow debris from valleys and flat surfaces of your roof. This helps prevent shingles from decaying beneath a moist layer of leaves, twigs, and dirt. Call Alltex or a qualified roof specialist if this is not a project you are confident in undertaking yourself.

If you have a flat or low pitched roof over all or part of your home or business, you should periodically check it for debris build up. If the roofing material is of non-granulated rolled goods (a smooth surface), it should be coated with an aluminum top coating for ultra violet sunray protection. In Texas, UV rays can play havoc with non coated flat surfaces. Also, if water ponds on a flat roof and the evaporation period is more than three days, the surface should be coated with elastomeric or other protective coating. For more information on coatings, visit the Roof Coatings Manufacturers Association Website. Ask an Alltex Representative for options and recommendations.
