"I cannot speak highly enough of Eagle Siding and their exceptional honesty and integrity. I recently contacted them for a second opinion after a storm chaser company told me that I needed a new roof due to damage caused by a recent storm. Upon inspecting my roof, Eagle Siding informed me that my roof was actually in good condition and did not require a replacement. They took the time to explain to me what they looked for during their inspection and gave me a professional opinion about my roof. I was incredibly impressed by Eagle Siding's honesty and transparency throughout the process. They could have easily recommended a replacement and taken advantage of my lack of knowledge about roofing, but instead, they chose to do the right thing and save me money in the process. Overall, I highly recommend Eagle Siding for anyone in need of roofing services. Their honesty, integrity, and commitment to their customers is truly unparalleled, and I am grateful to have found a company that I can trust for my future roofing needs. Thank you, Buck at Eagle Siding, for your exceptional service and honesty!"

"Capital was one of four contractors we interviewed. Jeff Moore was very easy to talk with, gave good information, and we felt he was honest and really wanted our business. Once we chose two roof colors we were interested in, Jeff provided us with houses in the area to look at to see how the roofs actually looked on houses. This was very helpful in making our decision. Capital got us on their schedule very quickly. The crew supervisor Azael was fantastic to work with. He explained about a dip in the garage roof and how they would fix it. It was reasonable, inexpensive, and we gave the approval. The crew completed the roof work in two days. They were prompt, friendly, and did a fantastic job of cleaning up. They even came back a few days later and ran the magnetic roller around the house again. Our roof looks great, and we would highly recommend using Capital for your roofing project!"

"Tom from KeyPrime provided us a competitive quote for redoing most of our exterior. We asked for a quote for vinyl siding and windows, gutters and roofing on our house and garden shed. We appreciated his patience and experience particularly explaining window types and brands."

"We had a storm come through in May and it did a number on our roof and siding. After calling several different companies. We settled on Capital Siding, as they were very polite, prompt, responsive. They were able to work with our insurance company, and our home owners association to get the job done."

"EXCEPTIONAL Experience working with Bormann Brothers! From my first phone call with Steve Bormann to my new roof being completed, gutters and gutter guards installed, the whole process was seamless. Steve listened to me, answered all my questions, understood the unique situation I was in with my roof and provided a fantastic solution that addressed my concerns, met my needs and gave me peace of mind; I was working with an experienced Contractor that understood construction/roofing and the whole insurance claim process. In addition, Steve, Nick and their crew are highly skilled and made some additional repairs while installing the new roof. A huge relief, I did not need to hire another contractor; they took care of it! The work was done exactly as explained and for the price quoted. Bormann Brothers exceeded my expectations, I would hire them again and highly recommend them!"
Bormann Brothers only uses one experienced crew. If you read our reviews they are all positive. If you hire us, you’re getting the same crew that did the work from the review.  You get the A-Team every time. You don’t have to worry about getting a C team like other bigger companies.
Nick and Steve Bormann started the company in 1997. They’re still at the job site every morning!

"Chase from Excel Renovation was great to work with regarding our residential garage roof leak. He was very personable and there was excellent/ professional communication in talking through the potential issue and then scheduling a time to meet. Chase ended up starting with a simpler repair approach first, re-fastening and re-sealing a roof flashing, which we agreed was the right thing to do for our type of roof leak (very small leak) and for this cold time of year (late Nov). He was very honest in what he thought was the likely issue and digging deeper right away in our case, instead of just resealing and testing first, may cause more harm than good. He would not take any money for the repair…I tried though. :-) He said to keep an eye on it during the upcoming rain and snow melt(s) and he could always dig deeper if needed in the spring, removing interior sheetrock and then applying water with a hose over suspected area on the roof. If you’re looking for an honest company that won’t steer you wrong, give these guys a call. I highly recommend this company and I would definitely work with them again!"

"I had a large branch from an oak tree fall over my house during a wind storm. I had my insurance company out for an inspection and was told I would need a new roof. J&B Roofing did a wonderful job with my new roof and wood repairs from the branch damage. Due to rumors about insurance abuse and fraud I felt the need to handle my claim on my own and Hilda from J&B Roofing was respectful of my decision. I am happy with the service and material I received, thank you!"

"Krech replaced our roof about 15 years ago. Did a beautiful job. Following recent hail storm we asked them to come inspect the roof Oscar came out a few days later and checked it out telling us the roof looked great, in part due to the high quality shingles they had recommended years ago. We greatly appreciate his skill, kindness and honesty; traits sadly in short supply these days. Can't recommend Krech highly enough. Awesome company and people."

Roofing FAQs, answered by experts

16-gauge galvanized steel staples with a minimum crown of 15/16 inches or 24 millimeters are occasionally used to install shingles. However, most shingle manufacturers or residential building codes don’t recommend staples as a roofing fastener. Roofing nails are preferred in most cases, especially in areas that get a lot of heavy wind.

The lifespan of a torch down roof depends on the number of layers installed. A single-ply system typically lasts between 10 and 15 years, while a multi-layer system with two or three layers can last from 15 to 25 years. Although a multi-layer option may be more expensive upfront, it provides a longer service life. Warranties often reflect this, with about 12 years for a one-ply system and 15 years for a two-ply system. For context, this lifespan is shorter than other common roofing materials like wood or asphalt shingles, which typically last 20 to 30 years, with high-quality versions lasting up to 50 years.

Roofers don’t typically replace vent pipes themselves, but they do handle the flashing and seals around vent pipes when working on a roof. During a roof replacement or repair, roofers inspect the vent pipe flashing for damage, replace deteriorated seals, and ensure the pipe is properly integrated into the roofing system to prevent leaks. If the vent pipe itself is cracked or damaged, a plumber is usually required to replace it, while the roofer ensures the roofing components around the pipe remain watertight.

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.

Walking on an asbestos roof can pose a risk. Asbestos roofing materials can become brittle over time, increasing the chances of them breaking or releasing fibers when stepped on. Additionally, walking on an asbestos roof without proper precautions can cause further damage to the material. If possible, avoid touching an asbestos roof in any way and consult with a professional about removing and replacing the roof.
