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.

Tile and shingle roofs both have their pros and cons. In general, tile roofs are a larger upfront investment. In some cases, they can cost twice as much as shingles, but they last much longer and generally hold their value better than shingle roofs. Shingle roofs, on the other hand, are budget-friendly and quicker to install.

Good news—asphalt shingles, including architectural shingles, are easily recycled. Talk to your roofing contractor to find out if recycling options are available in your area.

If recycling isn't available, your roofing contractor may recommend renting a dumpster, if your project is on the large side, or collecting the shingles in contractor bags to throw them away. Another option may be to donate new or gently used shingles to a local nonprofit.

You can technically install a metal roof over asphalt shingles, but it isn’t a good idea. This is because you’re essentially creating a moisture barrier under the metal, which can easily—and often does—lead to significant mold damage. Removing an asphalt roof isn’t terribly expensive, and some roofing companies might cut you a serious labor and disposal discount if you add it to a new install.
