"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

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.

Homeowners insurance does not usually cover roof soft spot repair. Since this damage is usually caused by wear and tear and often found on aging roofs, your insurance claim will likely be rejected. If a soft spot develops due to damage from a storm, repairs may be covered, but in general, expect to pay out of pocket for soft spot repairs.

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.

Whether or not the terms of your roofing estimate are negotiable depends on the contractor. Some professional roofers will be willing to budge on labor fees to some extent, while others will simply walk away from the potential work rather than lower their fees. In most cases, it’s best not to negotiate the terms, as lower labor charges could lead to your contractor cutting corners. Material costs aren’t negotiable, but you could purchase them yourself to try to save on delivery fees and markups.

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.
