"William Richmond, Inc. removed and installed a new asphalt roof for our house and shed. We experienced a quick turnaround from estimate to installation. Mr. Richmond provided a detailed explanation of the products he would install and of the expectations on the overall project. Communication was excellent throughout the project. The roofing crew arrived on time, completed our project in a day, and did an excellent job in cleaning up after the install. We would highly recommend the services of William Richmond, Inc. We look forward to working with Mr. Richmond on future projects."

"Worked very hard to get my roof replaced ASAP. I made them aware of our current leaking situation and my worry and they had new shingles and a crew here within 2 business days of me signing the contract and our roof was complete that day. Overall experience from quoting to replacement was easy. They were the lowest bidder out of 4 local contractors. We've had lots of rain since it was completed LEAK FREE!! Would definitely recommend them to a friend."

Roofing FAQs, answered by experts

A spray foam roof costs an average of $6,000 to install, making it one of the most affordable flat roofing options available. Costs can increase if you have a complex roof design with many roof vents or have a roof that’s larger than average. While up-front costs are relatively low, keep in mind that ongoing maintenance and repairs tend to be more expensive than you’d see with other flat roof materials.

Cool roofs last for roughly 15 to 30 years. You can install a cool roof coating over an existing roof, but keep in mind that this might not be worth it if your roof is near the end of its life expectancy. If your roof isn’t near the end of its life, adding a cool roof coating can make your existing roof more energy-efficient and help it last longer, so you’ll have to weigh the pros and cons.

No, you do not need gable vents if you have a ridge vent. In fact, gable vents would actually interrupt the process that ridge vents are set to conduct. You would be better off to decide between the two depending on your home’s needs.

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.

Many insurance policies will not cover a roof with two layers of shingles. An additional layer of shingles increases the risk of various kinds of damage, and insurers typically won’t pay claims on a roof with an overlay. Adding a layer of shingles may even jeopardize your insurance coverage entirely, so check your policy to ensure you stay within coverage guidelines.
