"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."

"Pfeifer Roofing is courteous, professional and prompt. I was given a free evaluation of my roof, shown samples of the products they use and pamphlets for their policies and products. The free estimate was detailed with multiple options for various avenues for next steps. The installation foreman and crew itself were incredible and communicated with me multiple times throughout the four-day roofing/gutter install, sharing their noticings while working and asking me for my input and preferences. They worked hard to clean up after each day, and the final result is fantastic."

"Roof Tek came out quickly, gave an estimate for the work on the spot and then repaired the day after we called to hire them. They located the source for our leak which was the kitchen exhaust fan and not really the roof itself. They also sealed up some other vents on the roof, cleared out our gutters and added moss treatment while they were up there too. They got the work done right before some really bad weather so, we really appreciated them fitting us in and the icy weather the following week tested their work! I definitely recommend them and would hire them again."

"Great! Felipe and his crew were very quick to respond to our emergency. They put in a temporary patch until they were able to redo the entire roof a few days later (as the prior roof was installed incorrectly). Felipe was easy to work with and answered every question we had. The crew worked super fast and did quality work at a reasonable price. I also liked how he guarantees his work. They cleaned up at the end very well and the roof looks great. I would recommend All Roofing Eagle to anyone and would definitely use them again."

"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."

"We had a leak on a Sunday morning. Within a few hours there was a team here tarting the roof. After consulting with us (roof had tiles, had leaked before, and the age of the roof) we decided to replace the roof. The team had to replace facia boards and gutters, so it was a longer process than most. The team was cheesy with communication and our roof looks great!!"

Roofing questions, answered by experts

Removing snow from your roof can help prevent ice dams, but the best thing to do is address insulation issues in your attic. If you do decide to remove the snow manually, you should always use a roof rake rather than a shovel. You shouldn’t climb your snowy roof in any circumstance, and roof rake allows you to remove the snow from the ground or a ladder. For the best results, remove snow as soon as possible after it falls.

EPDM roofs have a few common problems, most of which can be resolved with regular maintenance. This type of roofing is laid down in sheets with seams, which can be a starting point for leaks. Proper installation and roof sealing can often avoid seam issues. 

The material is also susceptible to tears and punctures from falling branches or other sharp objects. There are black and white versions of EPDM, and the black version is more prone to fade and succumb to UV damage. Regular roof inspections can protect the costs of rubber roof installation and extend the life of your roof.

Most roof leaks occur where shingles meet or where there are sealants or seams in the materials. This is common around skylights and at any point there is a break in the roof such as corners and edges. Roofing materials are incredibly strong and resistant when overlapping, but any change in that can cause gaps where water can enter.

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

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.
