"They have done an excellent job on the roof! The estimate was detailed and included pictures to highlight the roof issues. Other estimates were just a vague list of estimated costs and couldn't tell if they were going to resolve the roof issues. The team was responsive and the work was done beautifully. They did an excellent job with cleanup and we could barely tell that they were even there. Highly recommend them."

Roofing FAQs, answered by experts

Yes, shingles should overhang the drip edge, typically between 1/2-inch and 3/4-inch. An overhang shorter than 1/2-inch can allow wind-driven rain to get under the shingles and damage the roof deck or fascia. Conversely, an overhang longer than 3/4-inch increases the risk of shingles getting caught by strong winds, which can lead to roof uplift. Always check your local building code for exact overhang requirements in your area.

Ideally, you shouldn’t pay your roofer upfront unless you’re special-ordering materials. However, anything between 10% and 15% of the project’s cost is reasonable to pay upfront. Avoid making a final payment until after the roof gets completed.

The size of the dumpster will determine how many squares of shingles can fit in a dumpster. You can place between 4 to 20 squares of shingles in most standard containers.

Many homeowners believe that a modern home looks better with a flat roof than a sloped roof. A flat roof can provide several aesthetic benefits for modern homes. Among the pros and cons of a flat roof for a modern home design are the clean lines and straight edges that it delivers to improve curb appeal.

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.
