Cool Roofing - Cool Metal Roofing Information
Is it time to replace your
roof? Millions of roofs are replaced each year with ordinary asphalt
shingles, but let us discuss the benefits of metal roofing. Metal roofs
are superior to conventional roofing materials in 6 ways.
The first is that you won’t have to replace your roof nearly as often!
In fact, your new metal roof may be the last roof you ever have to buy
because the life expectancy of a metal roof is 20-50 years. How hold
will you be in 50 years?
The second superior aspect is the weight, compared with a normal roof
that weighs 750 pounds per 100 square feet, metal roofs range from
50-150 pounds per 100 square feet. Because of this, you can easily
install a new roof over the last one without the costly and time
consuming task of taking off the old roof.
Metal roofs are not combustible which is why metal roofs are given
“Class A” status which is the most resistant. You can also expect to see
less in the way of energy costs because the metal roof reflects much of
the direct sunlight that normal roofs eat up and translate back into the
house.
If you live in California or somewhere that has many different types of
houses, metal roofing can accommodate almost flat roof pitches without
risk of leaking. Most other roofs can have significant leaking problems
at more less than 15% pitch.
Finally, you’ll be able to enjoy your new roof much faster because of
the speed and ease of roofing installation. You can have a new roof in
about 2 days less than the time it takes for an asphalt roof. Add up the
benefits to a conventional roof and it is clear that a metal roof is far
superior in these six fundamental ways.
