"Pete (the owner) and his roofing crew (Genaro, Alberto, Pedro) were great! Pete replied promptly to my initial inquiry and came out right away to look at the roof. Following that, it took somewhat longer than I had hoped to get an initial bid and to actually start the job, but his bid turned out to be lower than the others, and I could see that the delay was for the right reason -- Pete always prioritizes the roof he's already working on to make sure it's done well and as quickly as possible, so a house doesn't stay unprotected for longer than necessary. Once they finally finished earlier projects and started working on our roof, they were 100% on task from start to finish. They are a small company and ours was a complex, 4000+ square foot roof that required ordering special materials along the way, so it took about a month to complete the job with 3 guys working 40 hours per week. However, I really appreciated the way they always started promptly on time each day and worked closely with my wife and I throughout the entire process to make sure work was being done exactly as we (and the City's historic rules) needed it done. Pete and his crew were friendly and very accommodating of special requests related to the historic peculiarities of our house, skylights, neighbor's concerns about parking, etc. Many parts of the roof required creative, on-the-fly problem solving, due to the non-standard construction of our 1800's house. Genaro, especially, was great at innovative problem solving and did beautiful work, but everyone on the team was super dedicated, hard working, and skilled. We have already had one heavy downpour since the new roof went on, and not a single drop got through! I can confidently recommend Positive Results Roofing if you are looking for a small, personable company that is licensed and bonded and does quality roof replacements or repairs for a reasonable price."

"They are experienced roofers that are proud of their work. Prices are competitive and I am glad I did not have to waste time collecting several quotes. They come to inspect your roof, explain in details roofing terms in a clear way I understand, then they give you the estimate and from there it is a straight forward process. Next thing I know my roof was repaired in a couple of days. The workers are hard working people and the supervisor is there to overlook everything and make sure to resolve any unpredictable situation. There was a bird nest near my chimney and they placed the nest with a couple of eggs on a nearby tree. That was so thoughtful! A few years forward, there is no issue on my roof. My house is 40 years old and I need a new roof to be able to install solar. But the repair done by KiTA guys was so well done that I am postponing. I will hire them again and recommend KITA Roofing for family and friends."

"I reached out to Apollo Roofing for an estimate because I had persistent leaks during the winter. I had called several roofers to get quotes for myself and my husband. Apollo?s estimate was the most reasonable price, and it didn?t compare to any of the other companies we contacted. Sam provided an estimate quickly, efficiently, and was incredibly professional and knowledgeable about roofs. We decided to go with Apollo Roofing, and it was the best decision we?ve ever made. We love our new roof, and we haven?t had any leaks since we had it installed."

Roofing questions, answered by experts

While you technically can add a roof over shakes or shingles, it’s not a good idea. Roofing over existing roofing creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.

Tipping your roofer or their crew is not customary or expected, but it is always appreciated. It is entirely up to you whether you want to give them extra money for their work. If you feel they have done an exceptional job, a tip can be a nice gesture. As an alternative way to show appreciation, you can provide coffee, breakfast, drinks, or grab-and-go snacks like cookies or doughnuts.

The type of roof and roofing materials that are best for your mobile home depends primarily on its shape and slope. Rubber materials, such as EPDM and TPO, are best for flat, low-sloped, or bowed mobile home roofs. Asphalt shingles or metal roofing are best for mobile homes with sloped rooflines.

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.
