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.
Our ShingleMaster status with CertainTeed roofing ensures
that our installers have been trained on the correct installation procedures
for all aspects of asphalt roofing.
