"All under one roof did a fantastic job removing two layers of shingles and installing new roof. The whole team was hard working and completed the job in one day. When they were done my yard was cleaned of all debris. I highly recommend All Under one roof."

"I had a leak that can be seen from a ceiling. Called several roofing companies and got no reply back. Used home advisor and have Andrea called me and scheduled the visit promptly for Freddy to come and check the leak. Freddy was very professional, identified the leak that was due to improper seal of one of the skylights and fixed it right away. He also checked my other skylights and some had the same problem which he fixed. Freddy checked my roof for issues and provided tips for maintenance so it can last long. Definitely will recommend Global Home Improvement, Inc as a honest and very professional company !"

"Obtained an estimate for a re-roof from Action and the level of detail was far above all other contractors I spoke with. Every possible aspect was clearly detailed in the spec leaving no room for hidden charges. The spec also included two variations to the approach as we spoke about , something dropped by other contractors. David also included CAD diagrams of how the tapered insulation would be applied which really helped me understand the process better David was quick in providing the estimate and responding to emails and addressed my repeated questions. The pricing was competitive with other estimates i received, but not overly aggressive I ultimately was unable to go with Action roofing due to scheduling conflicts (mine, not Action roofing) but would consider them in the future due to their professionalism and attention to detail"

"I first called another roofer who never came inside to look at the stains or went up on the roof. That roofer said by visual inspection he could tell I did not need a new roof and his company only dealt with replacements. But, he hazarded a guess at what was wrong and said if anyone actually went up on the roof, it would cost around $800. I then called Farina who scheduled an estimate; they arrived on schedule. The gentleman came inside and took pictures of the stains. I received an estimate about a week later and was asked to agree to it or not by email. I agreed and about another week passed and they showed up at my house to do the work, again going inside first to look at where the stains were. The actual work took less than an hour-so far, so good. Assuming that the leak is fixed, the only thing that could have been better was if I was told beforehand when they would do the work, instead of their just showing up. Luckily, I was home."

"If we could give Mighty Dog Roofing more than five stars, we would. Their pricing was excellent, their turnaround time was lightning fast, and the communication and workmanship far exceeded our expectations. From the moment Paul came to our home to inspect our old, leaking skylight, we knew we were dealing with a company that values professionalism and integrity. The crew replaced our skylight along with the extensive rotted roof sheathing around it. They also replaced a missing shingle and sealed a vent pipe and a second skylight at no additional charge. Their communication was excellent. They provided photos and videos before, during, and after the project. Mike, the outstanding on-site supervisor, checked in with us repeatedly, answered every question, and made sure we knew exactly what was happening. He and his crew also left the place spotless when they were done. We’ve hired many contractors over the years, and this was genuinely one of the best experiences we’ve ever had."

"Very easy to get in touch with! Whenever I had a question for Chad, he was always an easy text or call away. The quality of the work is good, and the price was about $100 less than comparable quotes I received from contractors using the same roofing system."

Roofing FAQs, answered by experts

Fall is generally considered the best time of year for roof repairs. The weather is temperate and typically drier, which makes for safer working conditions and fewer delays. The days are also still long enough to complete the work.

Spring is another good option and is a popular time for repairs to fix damage from winter storms. However, frequent rainfall can slow down progress. Spring may be a less busy season for roofers than fall.

Summer can also work for roof repairs, but extreme heat can make asphalt shingles too soft and difficult to work with.

It’s possible to walk on a clay tile roof, but you run the risk of breaking or cracking the tiles if you’re not careful, so it’s best not to walk on it if you can avoid it. If you or a contractor needs roof access, be sure to distribute your weight evenly and step on the portions of tile that are also supported underneath, which depends on your tile design. Walking on any roofing material is inherently dangerous, so wear rubber-soled shoes and use safety equipment if you need to access your roof.

You can technically install a metal roof over asphalt shingles, but it isn’t a good idea. This is because you’re essentially creating a moisture barrier under the metal, which can easily—and often does—lead to significant mold damage. Removing an asphalt roof isn’t terribly expensive, and some roofing companies might cut you a serious labor and disposal discount if you add it to a new install.

Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

Wooden roofs require regular maintenance, are prone to rot and mold, and are frequently the target of insect infestations. Natural wood is also excellent at absorbing and storing moisture—not a positive. In climates where the weather shifts dramatically, the wood can also crack, split, or warp.
