Q: Do I need gable vents if I have a ridge vent?

Roofing questions, answered by experts

Spray foam roofs don’t stand up well to impact, so they won’t last as long as something like a tar and gravel roof and other flat roof materials in areas where extreme weather is common. Due to the reduced durability, you’ll also need more frequent maintenance and repairs for a spray foam roof, and those costs will add up over time. Spray foam roofs are relatively uncommon, so you may also struggle to hire a roofing contractor who can install one.

Roofers most often use nails to fasten roofing shingles and other roofing materials. Nails have more holding power than staples and offer better weather resistance and longevity. However, it is possible to use staples instead of nails when installing a roof. Staples are less expensive, but not as high-quality.

The formula for calculating how many squares of roofing you need is pretty easy. Take the total amount of square footage and divide it by 100. With this formula in mind, a 2,000-square-foot roof would require 20 squares of roofing material to adequately cover it.
