Cool roofs last for roughly 15 to 30 years. You can install a cool roof coating over an existing roof, but keep in mind that this might not be worth it if your roof is near the end of its life expectancy. If your roof isn’t near the end of its life, adding a cool roof coating can make your existing roof more energy-efficient and help it last longer, so you’ll have to weigh the pros and cons.

No, a chimney crown is not the same as a chimney cap. A chimney crown is a flat cement area on top of a masonry chimney. It starts where the masonry part of the chimney ends at the very top and domes upward toward the flue opening. A chimney cap sits on top of the crown over the flue. It is usually made of metal and allows smoke to escape without letting in rainwater.

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.

Fall is generally considered the best time of year for roof repairs. The weather is temperate and typically drier, which makes for safer working conditions and fewer delays. The days are also still long enough to complete the work.

Spring is another good option and is a popular time for repairs to fix damage from winter storms. However, frequent rainfall can slow down progress. Spring may be a less busy season for roofers than fall.

Summer can also work for roof repairs, but extreme heat can make asphalt shingles too soft and difficult to work with.
