Get matched with top roofers in Sherburn, MN

The most common defect in a flat roof is leaking. Flat roofs have minimal slope, so water pools more readily on a flat roof than on a sloped roof, and the risk of the waterproof membrane failing increases with exposure. Tears and punctures from foot traffic and blown debris are other common problems, especially with single-ply roofing membranes like TPO and EPDM roofs.

The terms “roof shingles” and “roof tiles” are sometimes used interchangeably, but the term “shingles” most often refers to asphalt, rubber, metal, or slate shingles, and the term “tiles” normally means they’re made from clay or concrete. In all cases, shingles are small, rectangular components that a roofer layers in an overlapping pattern to protect the structure underneath from the elements.

Asphalt shingles have varying thicknesses across the length, so failing to stagger shingles from one row to the next will leave you with bulges and bumps if the thicker sections stack on top of each other. Not only is this unappealing, but it increases the risk of water intrusion. Stagger each new row by 6 inches to avoid this issue.

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.
