"The good experience with Raindrop started with the estimate; Lee was knowedgeable and up front with me about the need to fix my chimney before they could do the roof work; neither of the other roofing contractors had mentioned that. When I accepted their bid, but the work couldn't start for over a month, they held the original price even though the cost of materials had just gone up. When they came to do the work, they were courteous and always willing to answer any questions I had about the process. And Ryan, the owner, is a real sweetheart; he came by at the end to check and make sure I was satisfied, which I definitely was. I've already recommended them privately to 2 friends who are ready to redo their own roofs."

"I am 100% satisfied with the roof and gutter work done by Roof Tek. Jamie gave me a competitive, knowledgeable quote, and he provided insurance and license documents at our first meeting. His roofing crew is obviously very experienced; they completed the entire job in only a few days, and they left the job site immaculately clean. I inspected their work when they were finished and it was absolutely perfect. The new gutter system is solid and it looks great, and the new shingles and flashing are flawless. I was particularly impressed with their detail around the skylights and vent flashing. I was also impressed that the crew seemed happy and they worked well as a team."

"I needed a new roof, new gutters and an exterior paint job this spring. I did a bunch of research and chose JLV because they could do all of the work and had good reviews on Yelp and Angie's list. I have a 6000 sq ft roof and I wanted Malarkey shingles. JLV is Malarkey certified and trained. Asael responded to my quote request quickly as well as to my many questions, some of which required changes to the quote. Once the jobs started, communication between the crews and me and Luis, the supervisor and me were very good. I knew what was going on all the time. I'm very pleased with the work I got and will recommend them in a second."

"This is the second time we've hired Gentry Construction for projects. They're very busy and couldn't promise to finish until the end of summer, but they found a week in mid-July and finished in four days. Patio cover with a metal roof; re-roofing 60% of our house; front door rail. All top-quality work. Would definitely work with them again."

Roofing questions, answered by experts

Roof underlayment usually lasts as long as the roofing material that covers it, as it’s not directly exposed to the elements. In most cases, roofing companies will replace the underlayment each time they install a new roof. In some cases, particularly with slate, clay, or certain metal roofs that can last 50 to 100 years, your underlayment may require replacement within that timeframe, especially if you start to notice roof leaks.

Yes, clay and concrete tile roofs will keep your home cooler in the summer for two reasons. First, the material has low heat conductivity, so heat transfer from the sunlight and the outside air to your home will be very slow. Additionally, tile roofs have air gaps between the tiles and the roof decking, which helps further insulate your structure from heat gain. Light-colored tile is especially energy-efficient and will minimize how much outside heat transfers into your home.

Unlike wood decks, Trex decking doesn’t warp. That’s one of the key benefits of installing this decking material. Over time, common issues with these decks include hard water stains, mold or mildew growth, and stains from food spills. Thankfully, with proper cleaning, you can get rid of most stains and mold.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

Roofing jobs can be expensive due to the required materials and the dangerous nature of the labor. The cost to repair a roof ranges from $390 to $1,920, with an average cost of $1,150, depending on what kind of roof you have and any accessibility concerns. Replacing a roof is much more expensive at $5,890 to $12,800.
