"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

Roofing estimates and inspections are not the same thing. Roofing inspections (whether done with a drone or by the traditional method) help you find any damage or defects on a roof. You will pay a set fee for a roofing inspection and use it to get certification or to determine whether repair or replacement is necessary. Beware of unsolicited contractors coming to your home and offering a so-called free roof inspection—these are often scams.

Roofing estimates, on the other hand, are typically free and offered by a roofing company hoping to earn your business. Some roofing estimates are performed with drones, while other companies will still opt to send people up onto the roof. Either way, the estimate is for roof repair or replacement costs the company wants you to hire them for.

You only need to replace a roof before moving if it’s extremely old or has more than just a couple minor damages. For instance, leaks, uplifted shingles, or obvious holes are issues no one wants to deal with right when they move in, and will automatically repel potential buyers that might have otherwise been interested.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

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.

The terms “roof sealant” and “roof coating” are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof’s surface for waterproofing and UV protection. Products like roof caulk can also be called “roof sealant,” but the term is more commonly used for the protective coating.
