"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

The exact weight of a bundle of shingles depends on the shingle type, manufacturer, and other factors. It can weigh anywhere between 45 and 800 pounds.

No, you should not close or cover your gable vents in the winter. While it might seem logical to block cold air, heating your home creates hot air that rises and can cause condensation in the attic. If the vents are covered, this moisture becomes trapped, creating an ideal environment for mold and mildew. Keeping the gable vents open ensures proper ventilation, which helps dry out the attic, maintain even temperatures, and prevent moisture-related damage.

You should tarp a roof whenever roof damage occurs. Missing shingles and holes in your roof can cause roof leaks and problems that come with them. Tarping is a quick way to provide temporary roof protection while you wait for a professional roofer to make repairs.

A roof's lifespan can range from 15 to 200 years, with an average of 25 to 50 years, depending heavily on the material, quality of installation, maintenance, and local climate. Asphalt shingle roofs are common and typically last 15 to 30 years; three-tab shingles have a lifespan of about 20 years, while architectural shingles can last up to 30. More durable materials have longer lifespans: metal roofs last 30 to 100 years, clay and concrete can last 50 to 100 years, and slate roofs can last up to 200 years with proper care. Regular maintenance, such as cleaning gutters and replacing damaged shingles, is crucial for extending the life of any roof.

Whether replacing the entire roof or just installing roof shingle replacements in small areas, always pull up the old roof shingles. While you can technically put new roof shingles (but not other roof materials) over old shingles, this can add weight strain to the roof and prevent the new shingles from securing properly to the roof.
