"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 average cost to winterize a house is about $250, but it can range from $65 to $1,000 depending on the type of work that needs to be done. For homeowners that are experienced DIYers, it can save quite a bit on costs. However, you shouldn’t attempt tasks you aren’t familiar with or are potentially dangerous.

Tile and shingle roofs both have their pros and cons. In general, tile roofs are a larger upfront investment. In some cases, they can cost twice as much as shingles, but they last much longer and generally hold their value better than shingle roofs. Shingle roofs, on the other hand, are budget-friendly and quicker to install.

The easiest way to tell if your roof vent boot is leaking is to look in your attic for signs of water damage. You might see visible moisture, water spots, or mold on the roof decking around the roof vent or damaged or soggy insulation below it. If you don’t have access to your attic or aren’t sure if the vent boot is the issue, hire a professional to come inspect your roof and figure out the underlying issue.

A roof replacement can take anywhere from one to 14 days. For most homes, a full replacement that includes tearing off old materials takes about one to two days, though the average project can last up to 12 days. The exact timeline depends on several factors, including the roof's size and complexity, the type of roofing material, the crew size, and weather conditions. Certain materials take longer to install; for example, metal roofs can take seven to 14 days because the material is more difficult to work with than asphalt shingles, wood, or tile. A re-roofing project, where new shingles are installed over old ones, can take half the time or less. It's also important to factor in the time needed to obtain necessary permits. A professional roofing contractor will typically complete the job faster than a DIY approach.

Yes, impact-resistant roofs can lower your homeowners insurance. Some insurance companies offer discounts or reduced rates if you use Class 4 or Class 3 shingles.
