"Estabrook Construction replaced the vinyl siding, painted the exterior of my house, and replaced my patio roof with asphalt shingles. They did an excellent job! They did this work in a timely manner and they cleaned up after the work was done. I would highly recommend them to anyone who needs any kind of work on their home or business."

"I have always highly recommended Ocean Seven Builders. We have used them many times. They have done our garage roof, the main roof on our house, they have put in new roof for my town home, and all looks beautiful. The team is very prompt response. The crew is very friendly and professional. I will use them again for future needs."

Roofing FAQs, answered by experts

No, there’s no specific building code that requires a roof overhang. However, installing your roof with the standard 2-inch overhang is good practice, as it helps direct runoff away from your fascia boards and roof decking and into your gutters. Some overhang is especially important in areas that see heavy rainfall and snowfall, as the risk of water getting under the roofing material and causing water damage is much higher.

There are several signs that indicate you’ll need new underlayment. Clear signs include missing or damaged roofing and exposing the underlayment to the elements. Additionally, if you notice water damage in your home by the roof after a storm, it could indicate that your underlayment may need to be replaced. If your gutters aren’t draining properly, it could also lead to rotting or water damage to the underlayment.

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.

No, a chimney crown is not the same as a chimney cap. A chimney crown is a flat cement area on top of a masonry chimney. It starts where the masonry part of the chimney ends at the very top and domes upward toward the flue opening. A chimney cap sits on top of the crown over the flue. It is usually made of metal and allows smoke to escape without letting in rainwater.

Roofers most often use nails to fasten roofing shingles and other roofing materials. Nails have more holding power than staples and offer better weather resistance and longevity. However, it is possible to use staples instead of nails when installing a roof. Staples are less expensive, but not as high-quality.
