An article written for Ehow.com identifies major factors to consider when choosing roofing materials for your home. The author explains that your choice of material should be based on your budget, the climate in your area, and the type of structure you want your roof to have. Climate is the most crucial of these factors, considering that it won’t change much anytime soon.
If you live in a hot climate, you may want a metal roof to reflect heat, rather than asphalt shingles, which can end up absorbing a lot more heat into your attic. Conversely, if you live in an area that gets a lot of snow and rain, you’ll want to be sure that your roofing materials can stand up to moisture.
Metal is an excellent heat conductor and has a high thermal expansion coefficient; it absorbs heat fast and expands in the process. However, coating metal roofing with white paint reduces its conductivity and increases its reflectivity, allowing it to reflect heat back instead of absorbing it. You can consider installing metal roofing if you live in a place with a humid climate like Memphis, Tennessee.
Every house is different, and it’s essential to learn about yours before you buy roofing material. What is the slope of your roof? Slate, tile, and asphalt shingle roofs all work well at slopes of 4 inches in 12 or steeper. If your roof has a pitch of less than 3 inches per foot, you’re best off avoiding those materials and sticking with rolled asphalt roofing, or a more modern membrane material.
How much weight can your roof frame support? The author wants to point out that a roofing material will fit any type of roof structure. For instance, heavy materials like slate or tiles require a stronger support underneath, and shingles that are arranged side-by-side or overlapping should have sufficient slope to keep water from backing up. These areas will most properly be given attention by roofing contractors in Memphis like Roof Pro.
Choosing the right roofing contractors in Memphis, TN is just as important as the above-mentioned factors. To ensure that your roof does its job well, have it installed by reliable roofers like Roof Pro. It’s highly recommended to leave all aspects of the roofing project, even the consideration of the significant factors, to experts at the very onset.
