"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 !!

"Highly recommended! Adam Tweedy and his team repaired our 'cool roof' and three patio decks in just two days. The crew was efficient, careful with our furniture, and the installation was impressive. The roof passed the water test, proving its quality. An added bonus: they didn’t need to remove our solar panels, saving us time and money. For a reliable, water-tight roof at a reasonable price, call 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 can’t thank Jonathan and the team at Roofing Angels enough for the amazing job they did on our full roof replacement. This was a huge investment for us, and we wanted to make sure we hired the right company. After getting multiple quotes, we went with Roofing Angels because of their professionalism, competitive pricing, and outstanding customer service—and we’re so glad we did! Jonathan was incredibly helpful and responsive throughout the entire project. He kept us informed on the progress, answered all our questions, and ensured everything stayed within budget. The crew worked diligently and completed the job in a timely manner. They were also polite, respectful, and left the site spotless when they were done. Our new roof looks fantastic, and we have peace of mind knowing it was installed with top-notch craftsmanship. If you need a new roof, don’t hesitate—Roofing Angels is the company to call."

Roofing questions, answered by experts

Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.

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.

Yes, impact-resistant roofs can lower your homeowners insurance. Some insurance companies offer discounts or reduced rates if you use Class 4 or Class 3 shingles.

The minimum recommended slope for a porch roof is 1/4:12, which means 1/4-inch of rise every 12 inches of run. Slopes of 3:12 and 4:12 are more common and provide faster drainage for runoff. Make sure to choose a pitch that’s appropriate both for the climate in your area and the type of roof material you install. Hire a roofer if you need help determining what the right roof pitch is.

You shouldn’t put a new roof underlayment over an old one for a few reasons. Old felt must be removed in order to assess the condition of your roof decking, such as rotting wood or other structural issues. Also, if your roofer doesn't install a fresh layer of felt as is required by shingle manufacturers, your warranty may be voided. Finally, old underlayment removal is often included in the cost of roof repair or replacement, so there's no real benefit to leaving it on before installing a new layer.
