If you are considering asphalt roofing in Concord, MA, it is good to understand how the pitch of your roof affects your options. Asphalt roofing is the most popular roof type in America for many reasons, and it is the best option for most homeowners looking to replace their roof. But the pitch of a roof can affect whether you can use asphalt, as well as how long it will last as a roofing option.
What is Roof Pitch?
Roof pitch is a term used to describe the angle of your roof. A low-pitch roof will appear to be flatter, while a high-pitch roof is sharply angled. It is calculated by measuring the rise of the roof for every 12 inches of horizontal distance. For example, a roof with a pitch of 2/12 rises 2 inches for every 12 inches traveled.
Can the Pitch of a Roof Affect How Long the Roof Will Last?
It depends on the weather where you live and the amount of money you can invest in maintenance and repair. A low-pitch roof is easier and cheaper to repair, and it has a low risk of wind shear, causing damage to shingles in a storm. A high-pitch roof is less likely to collect water and debris on it, which can reduce the risk of decay from moisture and mildew.
Having a higher-pitched roof is an excellent choice for residents in Massachusetts because of all the snow and rain we get. But the higher the pitch, the harder it is for a roofer to get up on it to do repairs. Very high pitched roofs require special equipment and skills that come with a hefty price tag.
A higher-pitched roof will last longer in most climates. However, many homeowners prefer a roof with a lower-pitch to save money on repairs.
What is the Minimum Roof Pitch for Asphalt Shingles?
Some pitches do not work well for asphalt shingles. A low-pitch roof doesn’t drain water as efficiently, and the way asphalt shingles are placed is designed to move water down and away from the surface. Water can be driven under the shingles by the wind on low-pitch roofs, which can cause damage to the structure of your home.
The recommendations from asphalt shingle manufacturers is a minimum pitch of 4/12, but many roofers will go as low as 2/12. Anything lower than that requires a different type of roofing material.
