"Bill came over to my Mom's house and did a complete inspection of the roof. My Mom was concerned that she might need a new roof before the rains come.  Bill was so nice and honest with his discussion with my Mom and me.  He said that she had at least another 10 to 15 years of life left on her roof.  I asked if I could pay him for his time and he said no thanks.  
I have so much respect and appreciation for Bill and Jordan roofing, that when either I or my family needs a roof, I will use them !!
And I will recommend them to my friends !!

"I can't recommend Reign Roofing enough! They completed our steep roof project in just one week, and the quality of work is excellent. After receiving quotes from 10 other roofers, Reign Roofing stood out for its professionalism, reasonable pricing, and transparency. Our insurance (USAA) was difficult, offering only half of the replacement cost, but Reign Roofing worked with them to submit a detailed estimate and get our roof fully covered. We’re grateful for their hard work and help navigating the insurance process. Thank you, Reign Roofing!"

"We are giving Hoyt Roofing a 5 Star rating, because of the excellent job they did on the installation of our new roof. The whole process only took four days and the workers went over and above to keep us informed of the progress and maintaining a clean work area. We were impressed from the initial meeting where we discussed and deciding on the terms and conditions to completion of the job. They were not pushy or try to upsell their products. We highly recommend this company to anyone who needs a new roof."

"I had an awesome experience with Green Ladder Roofing. They repaired a few leaks on my roof and later did a full replacement when it was time. The crew showed up right on schedule, worked efficiently, and cleaned everything up afterward. You wouldn’t even know they were there except for how great the roof looks now. The customer service was great, we had an amazing experience with the team."

"I had been dreading getting my roof replaced because I assumed it would be a major headache, but Roofing Angels made the whole process so smooth and stress-free! Chuck was incredibly helpful from the start—he walked us through different roofing options, explained the costs, and even helped us navigate the insurance claim process. The crew was professional, polite, and hard-working. They arrived on time each day, worked efficiently, and kept the work area spotless. Even my neighbors commented on how respectful and clean they were! The finished product? Absolutely perfect. The new roof not only looks great but also gives us peace of mind knowing it was done right. I highly recommend Roofing Angels if you want a seamless experience and high-quality results!"

Roofing questions, answered by experts

DIY is not recommended due to safety and expertise requirements. Professional installation ensures proper alignment and sealing.

Condensation can occur on the inside of a roof, but it should always be temporary. It does not necessarily mean there is a roof leak. Condensation happens when the inside and outside of a house are at different temperatures. For instance, if it is hot during the day and then gets very cold at night, the inside of the house will be warmer than the outside and may cause condensation to form on the inside of the attic. This may not be cause for concern, but if it is happening frequently, it should be addressed; otherwise, it could cause roof leaks, compromise the structural integrity of the wood, or allow mold to grow.

More and more insurance companies are writing torch down applications out of their liability insurance for contractors. If torch down is covered, they generally require a worker to stay on site for two hours after the last flame is extinguished.

For this reason, cold application modified bitumen—also known as “peel and stick”—is becoming more popular, and torch down is decreasing in popularity. Modified bitumen is taking its place, as it uses both hot and cold applications.

Hail is unlikely to damage a tar and gravel roof because the hailstones will hit the protective gravel rather than your delicate roof membrane. A tar and gravel roof is the most resilient flat roof option, which means it’s the best one for areas that see hail, fallen tree debris, and blown debris from intense winds.

No, a chimney crown is not the same as a chimney cap. A chimney crown is a flat cement area on top of a masonry chimney. It starts where the masonry part of the chimney ends at the very top and domes upward toward the flue opening. A chimney cap sits on top of the crown over the flue. It is usually made of metal and allows smoke to escape without letting in rainwater.
