The Science of Roofing

What do you think of when you picture a new roof being installed? In the past, it was 10 or more guys with a pocket full of nails and a hammer, trying to tear it all off and put it back on in one day. Tar was used as flashing, and nobody gave a thought about ventilation. Roofing was much more affordable then, and it didn’t matter as much if it needed to be done again in 20 years.

With the cost of today’s roofing growing approximately 5% each year, a little more care is needed to ensure your roof is an investment that will protect your home for many years. We take a scientific approach to the roofing process by addressing three main concerns:

Insulation: If your current insulation is less than 12” thick, then too much heat is escaping into your attic. This causes ice damming and eventually leaks. It also causes condensation on the underside of your roof sheathing which could lead to delamination or mold growth.

Preparation: Do you have proper ice shield? Is there flashing at roof/wall transitions? Any loose or rotten plywood? These are all important issues to address in order to maximize the life of your new roof.

Ventilation: A balanced ventilation system is not only vital to your roof’s performance, it is a manufacturer requirement for warranty. A balanced system consists of 50% or more of combined net free air flow at the eaves and the remaining portion at the peaks.
