"After talking to my furnace/heating Company, I decided that my idea to have the chimney taken out and roof patched was overkill ---not going with Overhead Solutions had nothing to do with the quote or speed of their response. They were very good at both !!"

Roofing questions, answered by experts

Asphalt shingles have varying thicknesses across the length, so failing to stagger shingles from one row to the next will leave you with bulges and bumps if the thicker sections stack on top of each other. Not only is this unappealing, but it increases the risk of water intrusion. Stagger each new row by 6 inches to avoid this issue.

A spray foam roof lasts 20 to 30 years if installed and maintained correctly. Spray foam roofs should be recoated every 10 to 15 years to maintain the UV protection and waterproof surface of the foam material. The longevity of spray foam roofing will depend on the thickness and density of the foam, the protective coating, and how well it’s maintained.

A cool roof can be worth it in the right climate. Cool roofs are excellent at reflecting solar heat away from your home, so if you live in a warm or hot climate, they can be a great roofing choice. Some cool roofing materials are even eligible for tax credits. However, they cost more than traditional roofing and don’t retain heat as well as traditional roofing, so they’re not ideal if you live in a cold climate.

The most obvious and severe sign of a roof leak is the presence of wet spots on your ceilings, specifically on the top floor of your home. You can also identify a roof leak from your attic if you see sagging insulation or if you notice mold growth or water stains on the rafters or the underside of the roof deck. From the street, look for cracked or missing shingles, moss growth, and shingles that are curling upward, all of which can suggest a leak.

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.
