Attic and Roof Ventilation

One of the most common roofing problems typically stems from poor attic ventilation. It is vital for your roofing contractors to properly install the right attic ventilation to address two important factors involved in home comfort: heat and moisture.

What problems to you incur if your roof and attic are not properly ventilated?

Over time, the issues stemming from improper attic ventilation results in a damaged roof, higher utility bills and a potentially unhealthy living environment.

Shortened roof life.

Excessive heat and moisture literally bake the underside of your roof, greatly shortening the life of underlayment and shingles. Cracked shingles and premature granule loss can be signs of improper roof ventilation.

Ice damming.

When warm air rises to the roof deck of a poorly insulated attic in winter, it melts snow on the roof. The snow melt refreezes as it runs down to the cold lower portion of the roof, creating an icy barrier or “dam.” Subsequent snow melt then backs up behind the dam, resulting in leaks.

Mold and mildew.

Unhealthy mold flourishes in humid environments, triggering respiratory and other health problems for occupants and potentially damaging items stored in the attic.

Damp insulation.

When humidity levels are very high in an attic, condensation can form on the roof deck and drip down onto insulation. In the winter, you may even observe frost. Insulation that absorbs moisture can’t insulate as well.

Air conditioner replacement.

With excess heat building in the attic, an air conditioner will struggle to keep the air inside the home cool. This heavy load can wear on the unit and run up cooling bills.

Decay of framing and decking.

Continual moisture in an attic allows dry rot, which weakens the structural components of the roof and decreases roof value.

  • We needed a whole new roof. After his initial inspection, Mr. Knox took the time to explain what we needed, and did not try to up-sell us any extras that were not necessary, keeping the price very reasonable. The crew arrived on time and were extremely professional and efficient. The foreman on the job kept us updated, and they completed the job in less than two days. Roof looked great and the yard looked like no one was ever there. The crew even fixed some loose siding they noticed. They definitely knew their stuff. Highly recommended.

  • Only giving Chaz, Buddy & his crew 5 stars because this site won’t let me give them more. I don’t write reviews (ever) but wanted to share my experience with Knox Construction. Fast, super professional & did qualify work. Would recommend to anyone and already did!

  • These guys came here on Friday and went right to work, only stopping when a thunderstorm forced them stop. After it passed they stayed late and finished the shingles before stopping for the weekend. On Monday they finished the entire job and did it very quickly and efficiently. Very good clean up and great quality work and attention to detail. We will definitely recommend them in the future to anybody for work on their homes. Great job to Chaz and your crew!

  • Professional from the beginning to the end. Fairly priced, top-grade materials, good communication throughout. Chaz worked to squeeze us into the schedule because of our emergency. The crew members are highly skilled, hard-working, and true gentlemen. Offered excellent suggestions to resolve a couple unexpected issues.

  • They were professional, courteous and good at what they do. They showed up on time and worked quickly to replace our roof in just a few days. Chaz kept me well informed through the whole process. I am more than pleased with the way our roof looks as well. I definitely feel that I got my money’s worth and will definitely use them again when I have a need. I would like to thank Chaz and his crew for such a great job. A new roof is not a cheap expense and Knox’s Construction lived up too and far exceeded my expectations.

  • Completely satisfied. Had the roof and shed roof replaced as well demo of an awning and some gutter work for a very reasonable price. Chaz provided excellent communication before the project to schedule the work, during the project to provide updates and after to follow up and make sure everything was completed correctly. The crew arrived on time, started working immediately and cleaned up everything with no mess left behind at all. Would gladly hire Knox's Construction again.
