The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

Hail damage is bad for a roof because it can leave the roof vulnerable to the elements. Hail may leave more than dents or scratches behind. It can actually cause the shingles to crack, which means water can leak into your home from the roof. Hail can also wear down the granules on the shingles. Without these granules, the shingles are weaker and more vulnerable to the elements, particularly wind. If the hailstorm is accompanied by high winds, it may take your shingles with it.

Tar and gravel roofs last an average of 30 years, which is longer than the average lifespan of many other flat roofs. The gravel on top of the waterproof membrane helps protect the roof from UV damage and physical damage, so if you keep your roof drains clear and carry out annual roof inspections to catch issues early, you could see up to 40 years of useful life from your roof.
