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.

If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.

Manufacturers, insurance companies, and municipality regulations are phasing out three-tab shingles. Because of their short lifespan and lack of durability compared to other roofing material types, manufacturers are leaning toward better products, and cities and insurers are starting to require better building materials overall. However, 3-tab shingles are still for sale, and some roofing companies still install them.
