A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.

Chimney caps may be installed by a few different professionals, including a chimney sweep or a mason that specializes in fireplaces and chimneys.

EPDM roofs have a few common problems, most of which can be resolved with regular maintenance. This type of roofing is laid down in sheets with seams, which can be a starting point for leaks. Proper installation and roof sealing can often avoid seam issues. 

The material is also susceptible to tears and punctures from falling branches or other sharp objects. There are black and white versions of EPDM, and the black version is more prone to fade and succumb to UV damage. Regular roof inspections can protect the costs of rubber roof installation and extend the life of your roof.

Roofing estimates and inspections are not the same thing. Roofing inspections (whether done with a drone or by the traditional method) help you find any damage or defects on a roof. You will pay a set fee for a roofing inspection and use it to get certification or to determine whether repair or replacement is necessary. Beware of unsolicited contractors coming to your home and offering a so-called free roof inspection—these are often scams.

Roofing estimates, on the other hand, are typically free and offered by a roofing company hoping to earn your business. Some roofing estimates are performed with drones, while other companies will still opt to send people up onto the roof. Either way, the estimate is for roof repair or replacement costs the company wants you to hire them for.
