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.

Technically speaking, yes, verbal agreements and “handshake deals” can be legally binding contracts that will hold up in court, but the suing party will need to be able to prove that the parties entered into the contract. Even though verbal and handshake deals can be binding, it’s risky to rely on these types of agreements for anything, including roofing projects. Always aim to get your contract in writing, and make sure it includes all terms and that you don’t agree to additional terms that don’t appear in the contract.

A roof's lifespan can range from 15 to 200 years, with an average of 25 to 50 years, depending heavily on the material, quality of installation, maintenance, and local climate. Asphalt shingle roofs are common and typically last 15 to 30 years; three-tab shingles have a lifespan of about 20 years, while architectural shingles can last up to 30. More durable materials have longer lifespans: metal roofs last 30 to 100 years, clay and concrete can last 50 to 100 years, and slate roofs can last up to 200 years with proper care. Regular maintenance, such as cleaning gutters and replacing damaged shingles, is crucial for extending the life of any roof.

Architectural shingles typically last between 20 and 30 years. While some manufacturers provide warranties for 30 to 50 years, particularly for extreme weather, achieving such a long lifespan is uncommon. The actual life of your shingles can be shorter if you live in an area prone to strong winds, hailstorms, or other severe weather. To avoid the risk of roof failure and costly water damage from leaks, it is recommended to replace your roof before it reaches the end of its expected life. Scheduling regular roof inspections every few years is a good way to assess your roof's condition and determine the best timeline for replacement.
