Customers say: Quick response

"I had storm damage on my roof that had caused my ceiling to collapse in places. After reviewing different companies I chose three and filled out online submissions for quotes. Within an hour Tom had contacted me and gathered all the general information. The other two companies never responded at all. The next day Wes showed up and inspected our roof and ceilings. He took photographs and covered everything with me. The next day Tom sent me some of the photos saying it looked like a great opportunity for homeowners insurance to cover some of the damage. I had not even considered that. Tom walked me through the insurance claim and also dealing with the insurance company which was not always easy. In the end insurance covered practically everything. The work was flawless by the crews who worked on my house. New roof, new vinyl siding with fascia and trim. New gutters. My house completely transformed. Bob the Builder is Amazing!"

"I had a great experience working with Guardian Roofing Systems. From start to finish, they were professional, prompt, and thorough. The team showed up on time and completed the job within the timeframe they promised, which I really appreciated. What stood out most was how clearly they explained every step of the process—from the initial inspection to the final cleanup. They took the time to answer my questions and made sure I understood what work was being done and why. Overall, I’m very satisfied with the quality of their work and the level of service I received. I wouldn’t hesitate to recommend them to anyone in need of flat roofing services."

"Where everyone was trying to get me to replace my roof Chris came out and looked at my roof found a problem and was able to repair it. He is really kind and polite and tries to find the best solution, easy to work with and not a pushy salesman. He stands behind his work. On the day he came out, he came early to beat the rain that was coming that day. This is how contractors should be."

"We had been dealing with a roof leak at our home and had several different companies come out to give us quotes. Unfortunately, replacing the entire roof was not within our budget. All Available Roofs was the only company willing to work with us and provide a reasonable solution to repair the roof. We are extremely happy with the work! Brandon was very professional, honest, and communicative. He explained exactly what work needed to be done and made sure we understood everything before completing the repairs. Since the repair, we’ve had several rainstorms and, thankfully, not a single leak! We truly appreciate the quality of the work and the excellent customer service. We highly recommend All Available Roofs to anyone looking for a reliable and professional roofing company!"

Roofing FAQs, answered by experts

Thatched roofs are expensive for two main reasons: high labor costs and low supply of available roofers. The labor is more intensive for a thatched roof than other roof materials, so your contractor will work longer and charge more for the installation. There are also few professionals with the specialized skills and experience to install thatched roofs. Since the supply of available professionals is low, the cost of compensation is high.

If your home doesn't have gutters, you can still hang Christmas lights on the roof using specialized clips. Use roof clips designed to attach to shingles or fascia. For tile roofs or the edges of the rooftop, consider using parrot clips. Adhesive light-hanging clips are also a great option. It's important to avoid using nails or staples, as they can damage your roofing material. For unique or complex installations, it's best to consult a professional Christmas light installer to find the safest and most effective solution for your home.

Manufacturers, insurance companies, and municipality regulations are phasing out three-tab shingles. Because of their short lifespan and lack of durability compared to other roofing material types, manufacturers are leaning toward better products, and cities and insurers are starting to require better building materials overall. However, 3-tab shingles are still for sale, and some roofing companies still install them.

You should definitely be wary of roofing contractors who offer significantly lower prices than their competitors. Most roofers in the area are all dealing with the same cost of materials, and labor costs are often comparable, too. If they’re significantly cheaper than other companies around, it could be a scam. Read reviews and ask other roofing companies and contractors if they’ve heard of the suspected scamming company.

Technically speaking, yes, verbal agreements and “handshake deals” can be legally binding contracts that will hold up in court, but the suing party will need to be able to prove that the parties entered into the contract. Even though verbal and handshake deals can be binding, it’s risky to rely on these types of agreements for anything, including roofing projects. Always aim to get your contract in writing, and make sure it includes all terms and that you don’t agree to additional terms that don’t appear in the contract.
