"Richard came out, found there were several gaps in the roof, and he repaired them quickly and cleanly. He also suggested that due to the high temperatures and strong winds in our area that we have a yearly checkup every fall before the rainy season."

"David from Clearview Roofing was fantastic in helping replace the roof at my daycare center. We had a huge leak, and he was incredibly speedy with the repairs. He took care of everything from A to Z, making the whole process smooth and stress-free. Highly recommend!"

"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 never thought I'd describe a roof replacement as a pleasant experience, but here we are. From the start, Jonathan and the team at Roofing Angels were a breath of fresh air. We got multiple quotes, and Roofing Angels wasn’t the cheapest, but they were the most transparent and professional. Jonathan took the time to inspect our roof thoroughly (unlike others who barely looked at it) and explained why certain materials were better than others. I appreciated that he wasn’t just trying to upsell us—he genuinely wanted us to make the best choice for our home. The crew was incredible. They arrived early, worked efficiently, and kept us updated throughout the process. I loved how respectful they were of our space—our driveway and yard were spotless when they finished, which I can’t say for other contractors we’ve worked with in the past. Now, our house looks better than ever, and I actually feel relieved every time it rains, knowing our roof is rock solid. If you want a team that truly cares about their work, look no further than Roofing Angels!"

"We had several bids and there were definitely some diff in approach for our roof replacement. We sent several emails to Eric for his opinion and he was always happy to respond. He was not the lowest bid and not the highest, but he was the most responsive. He provided recent referrals and all of them were more than happy with him, his crew and their work- We could not agree more. So glad we went with 3rd Gen. The crew was AWESOME! Clean, polite, and experts in their field. That was proven when the inspector told us ours was just about the best roof he had seen in his 32 years inspecting!"

Roofing questions, answered by experts

The length of time you can leave a leaking roof before it causes damage will vary greatly depending on a variety of factors. The best approach when it comes to roof leaks is to play it safe and fix it as soon as possible, whether you take the DIY route or hire a roofing professional to inspect, diagnose, and repair the problem.

Yes, many contractors offer warranties for their work. Confirm terms before hiring.

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best. 

Verify that your roof is licensed and insured by visiting your state's contractor's licensing association. Most states have a database to double-check your contractor's name and address against the information provided. The contractor should also display both their license and insurance on their website with links to the related agencies.
