Roof Venting and Warranties.

This has been one long hot summer. We are into our 4th heat wave and one more is coming. Over the last ten years we have seen the roofing shingle manufactures stress the need for effective ventilation. If you have subparr intake and exhaust vents in your roof system, take a quick trip up into your attic crawl space and you will determine (sweating profusely or becoming faint) one of the reason this is so: heat build-up. Thats means it may be 90 degrees outside but it could easily be 150 degrees in the attic without good roof venting- and it may stay excessively warm for a much longer duration even as the ambient temperature begins to drop outside.

Besides raising cooling bills or making the house uncomfortable, it can cause your roofing material to wear out prematurely. One of the reasons the shingle roofing manufactures require proper venting is to keep their shingles from failing. However, if you choose not to follow their guidelines, then you may not have a leg to stand on when your 30 year roofs begins to fail at 10 years. Roof warranties are tricky, but failing to follow the manufactures guidelines will generally void your ability to sucessfully win a claim.

One way to avoid the heat build-up is to install a ridge vent. This continuous roof vent system is one of the best ways to move hot or moist air out of your attic. But don’t forget, it only works if you have good intake vents for it to draw from.

So enjoy summer and stay cool, but make your roofing system is not baking away your roofing and its warranty.
