Get matched with top roofers in Jackson, MN

A metal roof can last anywhere from 15 to over 100 years, with an average of 50 years, depending on the material, installation, and environment. The specific metal is a key factor: aluminum roofs may last 20 to 45 years, while steel can last 30 to 60 years. Tin can last for up to 75 years, and more durable options like zinc, stainless steel, and copper can last from 80 to over 100 years. Factors that can shorten a metal roof's lifespan include living in a coastal region with corrosive salt air, improper installation (such as laying over old shingles), and failing to inspect and replace fasteners, which may wear out before the panels.

This will depend on your existing roof to some degree, but it’s common to raise a roof 4 to 8 feet. The exact amount you can raise is subject to the existing structure. For most homes with average roof slopes—20 to 45 degrees—you can raise the roof around 5 feet.

Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.

Flapping shingles, or shingles that are lifting or curling away from your roof, can be glued back into place using roofing cement or sealant. Apply the glue underneath the shingle, then press it down firmly. You can leave a brick on top of the shingle to hold it in place overnight while the sealant dries.
