Roof/Attic Venting

Good roof/attic venting can help to keep the roofing material and framing in good condition. It can also to reduce heat build-up in attic spaces. See the topic page on Roof Venting Systems. Proper attic venting is also a code requirement and its absence can nullify the warrantee on many roofing products. But attic venting is unlikely to cool an overheated house. And attic fans are not much better than passive vents in as a cooling system.
