POOR VENTILATION AND OUTDATED LOW QUALITY MATERIALS, SYSTEMS AND FIXTURES PRESENT IN MOST ROOFS
So many recently built houses as well as the older ones here in Texas feature low-cost materials, systems and fixtures that may be outdated or of an inferior quality. When you see houses and shingle roof properties with 20 Yr. shingles, unpainted rubber boot pipe jacks, plastic and metal roof vents, old chimneys, turbines, staples, felt paper, cheap wood, walls without flashings, skylights, flat roofs etc., you can be sure that it will not be long before they start leaking, breaking, rusting or losing proper functionality. Usually little or no upgrades are being done to most roofs since many homeowners are not educated about this problem or they have not seen leaks inside yet. Most roofs have either been repaired for leaks or completely replaced when they were not even that old, just because no other alternatives were offered to the homeowner.
The ventilation of your roof is extremely important as it may either shorten or prolong the life of your roof. Unfortunately, it is quite common to see houses with a large attic and just 1 turbine or 2 turtle vents to allow the hot air to escape the attic. This lack of ventilation creates a bad situation when the shingles of your roof begin to bubble and burst from the intense summer heat applied to both the interior and the exterior of the shingles. Since your shingles are made of asphalt, which is a petroleum product that can bubble with extreme heat, the shiny ceramic granules of the shingles, that is what protects the roof from the sunrays, will be removed little by little when these bubbles pop making your shingles age faster. The extreme summer heat also affects all the other roofing fixtures that have not been painted and for this reason, in order to protect them, they should be painted. To properly ventilate your roof, the right combination of vents must be present in both the lower and the higher parts of your roof. Think about the ventilation of your roof about the same way you breathe. When you inhale, it is the equivalent of your attic also inhaling the fresh air in from the lower soffit vents to the attic. And when you exhale and let your air out, it is the equivalent of when the attic is exhaling the hot air from the top vents of your attic. The combination of both will make your attic cooler, will help you prolong the life of your shingles, will eliminate moisture, will reduce your electric bill and will expand the life of your A/C unit.
Not only you need to make sure that most of the hot air is escaping out of the attic, but you must also make sure that you have enough soffit vents below so fresh air can enter the attic and can push the hot air out. Unfortunately, this problem will also continue affecting many new homes being built today simply because these cheap low-quality roof fixtures, systems and materials are still being used by some developers and builders on numerous homes and properties. In the case of older homes, it is understandable that some of the modern fixtures and systems may have not been available, but for recently built homes, we feel that there is no excuse. It is hard to believe that placement of better fixtures and systems is not happening when the difference in price between the new ones and the old ones may be just a few dollars. Please note that this is the main cause of why so many roofs are aging prematurely here in Texas. A roof that is not properly ventilated will not last long. The same its true about having quality roof fixtures. If they are not present, your roof will leak at some point. Another piece of information that you should know is that in the event of a hail storm, if your roof has lost tons of granules because of poor ventilation, your insurance company may deny your claim stating that because not enough ventilation and granule lost, it is hard now to recognize hail hits when there are not many granules left on your shingles.
