It is extremely important that roof structures are properly ventilated. Ventilation has often been an afterthought by builders who are more concerned with cosmetic appearance and maximizing profits. It is left to the smart homeowner to insure their home is protected from excess moisture and resulting mold and mite propagation, by proper ventilation.

Proper ventilation is critical for keeping moisture out of your home. Good Ventilation also exhausts the build up of summer heat in your attic. The wrong combinations of moisture and heat destroy wood structures, create attractive environments for the growth of molds and the breeding of mites. Poor ventilation will raise your cooling bills and make your home uncomfortable.

Your new roofing warranty also requires proper ventilation. Without good ventilation, your new roofing materials and your wood structure are in harms way and will not last like they should. Poor ventilation can and will destroy roof decks and create problems with roofing materials. Good ventilation is the answer and any roofer chosen must be accounting for good ventilation.

All portions of the roof structure need an air intake at the eave and an air exhaust at the ridge of the roof. These vents must be sized properly to allow the right volume of air to move through the attic to pick up the moisture that is entering the attic from the interior.

Concerns with Ventilation occur during 2 Seasons.

Texas gets hot in summer and our attics get even hotter. This hot is hard on building materials. Attic temperatures can soar to 170 degrees in a poorly ventilated attic. This adds stress to your plywood deck and roofing materials. Stress shortens the life of materials.

Proper ventilation can therefore save you money in summer and make you feel better too.

Moisture is the villain in winter. Texas roofs are usually well insulated. This means that the warm interior is well separated from the cool attic space EXCEPT where the warm heated air in your home leaks into the attic space around light fixtures and bathroom venting ducts. At these small micro-locations moist warm air from cooking, laundry, and shower activities rises and penetrates through air gaps into the attic space.

Warm, moist interior air mixing with the cold air in the attic allows the formation of a dew point. This moisture collects on insulation, rafters, roof sheathing- on anything where the dew point is reached. To prevent reaching dew point in your attic there must be a free exchange of dryer air from the outside environment. Good Ventilation creates this free exchange and thus prevents moisture problems.
