The lifespan of a torch down roof depends on the number of layers installed. A single-ply system typically lasts between 10 and 15 years, while a multi-layer system with two or three layers can last from 15 to 25 years. Although a multi-layer option may be more expensive upfront, it provides a longer service life. Warranties often reflect this, with about 12 years for a one-ply system and 15 years for a two-ply system. For context, this lifespan is shorter than other common roofing materials like wood or asphalt shingles, which typically last 20 to 30 years, with high-quality versions lasting up to 50 years.

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.

Most traditional lenders will not loan against a house with a leaking roof, and some lenders won’t lend against a home with a roof near the end of its lifespan. If the roof on your new home is in poor condition, you may need to have the seller offer a credit for a roof replacement after closing, or you can opt for a renovation loan—also called a 203k loan—to bundle the house and the roof replacement into one loan.

Underlayment is required by building code, so any roof installed without it is technically against code. The underlayment acts as the second layer of defense against water, so installing a roof without underlayment means a much higher risk of roof leaks. You’ll have the best chance of avoiding roof leaks if you install drip edge flashing covered by underlayment, and then install your roofing material over that.
