"Great company. Workers were professional & pleasant to have around. They were recommended by a friend and I would recommend them to a friend. Almost a year later and I am very happy I went with these guys.
Bruce didn't respond within 24 hours; however, he bothered to address my
many questions and was very knowledgeable ( unlike most roof companies I talked to).
Roof looks great.

"I have only positive things to say about Rhinos Roofing, Miguel and his crew. Miguel is very easy to work with and professional. The price was reasonable. His crew worked tirelessly and did a great job on my very steep roof. Miguel also put insulation and an attic fan in the attic, which makes such a difference in the temperature upstairs! They were on time, pleasant, neat and always closed the gate to my backyard so my dogs wouldn't get out. I got quotes from other roofing companies, some that were more expensive and did not pay attention to details like that. I highly recommend Rhinos Roofing."

"The service was excellent. We have a large roof with many steep angles. Crew was on time every day. Buzz would stop by a few times each day to see how things were going and help with the clean up. You could see his employees were happy to have him as their boss. I would highly recommend them if you need any of their services. Grant Ell"

"Steve from Smart Roofing Systems was amazing! As soon as I submitted my request he gave me a call with pricing and scheduled an immediate appointment. He knew immediately what the cause of the roof leak was. He is extremely knowledgeable about roofs and gutters. His prices are fair and his service was very timely. He definitely saved me from a major disaster. Within two days of his repair to my roof we we had two major storms. Half of my home would have been flooded! Many, many thanks to Steve Gubera from Smart Roofing Systems!!!!"

Roofing questions, answered by experts

Building an A-frame roof falls under the category of constructing a steep roof. While its structure is relatively simple, its height and requirements for more materials than a shallow roof design can increase its cost significantly. Expect prices for building an A-frame roof to hover around average to slightly above average.

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.

There are several pros and cons of flat roofs. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof—usually due to a bad seal—has the potential to let in a lot of water. They don’t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the weight a bundle of shingles adds to your structure. In most cases, it’s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.
