Roofing questions, answered by experts

The level of underlayment’s water resistance will depend on the type of underlayment. The most popular underlayment, felt, is water-resistant, but it can’t withstand long direct exposure to rain or the elements. 

Synthetic underlayment is more waterproof, but asphalt is the only fully waterproof type of underlayment.

A roof replacement will usually include removal of your old roof, shingle replacement, and a new roof underlayment, but it may only include adding new shingles if you’re layering new shingles over the old shingles. If you have signs of roof leaks or your roofer finds water damage to the roof decking underneath your old roof, it can also include replacement of the OSB or plywood decking that lays over your rafters and supports the roofing material above.

Shingle damage comes in many forms, and the damage usually depends on the wind speed and the shape of the roof before the winds. Typically, when shingles are damaged by wind, they become torn, creased, or detached from the roof. Some might go missing entirely. More extensive roof damage might occur if a tree branch or other debris has fallen onto the roof as a result of the windstorm.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.
