"Overall, the job went very well. Aaron was the supervisor and was able to expedite my job to a window in his schedule that no other contractors were able to accommodate. There was a nice week between storms that he got his crew in to remove the old tiles, clean up, perform inspections and get the new materials installed. There was a minor glitch in the removal part of the job (a rain gutter was damaged), but Aaron handled it exceptionally. At the end of the job, I asked Aaron to take my phone camera onto the roof and take pictures, since I can't get up there myself to inspect. He provided excellent photos of all the critical areas of the roof, louvers, pipe outlets, etc. He even provided photos of the chimney stucco that shows extreme weather damage, so I can show them to the next (stucco) contractor for that upcoming job. Thanks Aaron."

"After having my roof inspected by two other roofing companies, I hired Advanced Roofleak. Their pricing was competitive, and they offered a different type of roof replacement that avoided the old roof having to be removed. I'd never heard of their process so I researched it and discovered it was widely used, and was particularly advantageous to buildings in coastal areas of the US. Erik was prompt, the crew was great, and the cleanup was spectacular. My only complaint was that I had delays getting my call returned when a minor problem occurred. That said, Erik, Sr came out and took care of the issue. I've had no other problems. Would I recommend the company? I would, and I'd use them again if I needed any further roofing work."

"Working with Chasen at Smart Solar And Roofing (and his team) was a fantastic experience. His knowledge of solar and roofing made everything clear and easy to understand. Chasen’s customer service truly stood out; he was always available to answer questions and address concerns promptly. He streamlined the entire process, handling everything efficiently and professionally. I highly recommend him for any solar or roofing needs."

Roofing FAQs, answered by experts

Yes, shingles should overhang the drip edge, typically between 1/2-inch and 3/4-inch. An overhang shorter than 1/2-inch can allow wind-driven rain to get under the shingles and damage the roof deck or fascia. Conversely, an overhang longer than 3/4-inch increases the risk of shingles getting caught by strong winds, which can lead to roof uplift. Always check your local building code for exact overhang requirements in your area.

Roofing estimates vary for many reasons, but the most significant ones include differences in the cost of labor based on the contractor’s experience and overhead costs, as well as the quality of the materials your roofer will use for the job. You should get your estimates itemized and make sure your contractors include details about the materials they plan on using. Doing so allows you to compare not only based on the cost but also the value that you’ll get for your money.

Tar and gravel roofs last an average of 30 years, which is longer than the average lifespan of many other flat roofs. The gravel on top of the waterproof membrane helps protect the roof from UV damage and physical damage, so if you keep your roof drains clear and carry out annual roof inspections to catch issues early, you could see up to 40 years of useful life from your roof.

The amount of hail damage that warrants a roof replacement depends on the size of the hail. In many cases, a roof replacement is needed if your roof gets hail that is 1 inch or larger in diameter. You may also need to replace a roof due to hail damage if you notice several dents in the shingles or there are seven to 10 hail impact marks within a 10x10 foot area on your roof.

You’re going to need a permit for nearly every roof-raising project. This is a very important step, as the work you’re doing has serious safety considerations. Professionals are the ones to handle this type of work—including sourcing the permits—as they have the expertise required to perform the work safely. Insurance and warranty are usually voided if you do this work without a permit, and you may even be required to halt construction and tear it down as a penalty for working without a building permit.
