Roofing questions, answered by experts

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.

A tarp can temporarily stop a roof leak, but how long the solution works heavily depends on the placement and size of the leak. While a tarp can be a temporary solution, it’s crucial to have a professional inspect and repair the leak as soon as possible to implement a permanent fix.

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.

Homeowners insurance sometimes covers roof decking, but it depends on the cause of damage and whether the decking was properly installed. If the roof decking was damaged by a severe storm, then it will likely be covered. Insurance may also pay for roof decking work if building codes require it. However, insurance won’t cover damage caused by normal wear and tear or poor maintenance practices.

In most cases, no, roofers won’t need to come inside. Some reasons roofers may need to come inside are to assess ventilation. inspect roof leaks, or check for any structural concerns.
