This paper presents the findings and conclusions of that analysis.

Do you know the warning signs of poor ventilation in a house and attic? Proper ventilation is important in many ways and one of the first big things to know is that it can prolong the life of your roof system. It can also help lower your attic temperature and thereby reduce HVAC wear and tear, which may help lower utility bills and the likelihood of costly repairs. And last, but definitely not least, attic ventilation can help reduce the risk of mold, which can protect the health of your family. All-in-all, attic ventilation offers a long-term return on investment as well as potential preventative health benefits.

Even the smallest details play a role in a roof's effectiveness and integrity. Shingles and flashing are among the most noticeable roofing materials, but roof nails often get overlooked—despite being just as important as more obvious elements.
