"The contractor we hired to do the work went out of business without telling us and we were stuck. Brian to the rescue. Even though our roof was much steeper than he usually works on he agreed to replace the glass in our three skylights. He did an excellent job and I couldn't be more thrilled. He prepped the roof one day and finished the job the next. It is a real treat to be able to see through our skylights again. Thank you Brian."

"I contacted M and J roofing about a leak. Lous response was quick and after inspecting my roof responded with urgency. I had many roofs installed over the past several years none of which seem to work due to the pitch. The most recent roof I put on was a metal roof, which was the source of many of the problems. After Lou inspected it he told me what needed to be done and after agreeing on the contract he started immediately. They are prompt and professional and both him and his son Nick are two of the kindest human beings I ever met. They told me they'd be here at 8:00 a.m. and they were here before that, they started at 8:00 and we're done by the end of the day. Lou and Nick kept me posted each step of the way and during the removal of the metal roof they showed me what went wrong and explained why it went wrong. In short it was because of companies or people that install roofs that don't care about their work that care about ripping off unsuspecting customers. That is why in closing I will say M and J roofing should be the only and I am stressing only company anybody should want to do any work on their roof."

Customers say: Super punctual

"L&L made several visit including Saturday and Sunday to evaluate the job and made several suggestions as to the best way to replace the roof without any damage to the interior of our house.They promised to pick a good day to do the job and complete the job in one day. They arrived at about 7:30 AM with a crew of about 10 workers and had the complete roof replaced and the yard completely cleaned up before 4:30 PM. This included new lead flashing for the chimney and replacing 2 sheets of plywood. In addition they guaranteed the workmanship of the roof for as long as we owned the house. We had no problems at all.

"We just had our house and 1-car detached garage re-roofed this week and I absolutely loved my experience working with Blake and the team. They actually got on the roof and looked. Once the job was scheduled to start, they were extremely punctual, they worked extremely fast and the quality is amazing. They also did a good job cleaning up as much as they could. Would use them again without hesitation. Thanks!"

"Antonio Showed Up and explained all my roofing options, Displayed Samples of his roofing materials. I was able to view the different color and style options between Owens and Certainteed asphalt shingles. Selected my color and shingle. I did my own research and went with the Certainteed Landmark in Resawn Shake color. They showed up at 7:30 AM and proceeded to wrap my house in a Gray Fabric Tarp to protect it from Falling Shingle , Nail and Plywood Removal Debris. Antonio placed copper flashing around my chimney and replaced my vinyl siding back in place along with recaulking my chimney flue cap to protect against rain and water damage. No hidden cost at the end of the job. We were in constant communication throughout the whole process including the Plywood cost per sheet installed. 10 Year Warranty on his Labor against any Leaks was also an Added Benefit. The shingles chosen were rated best buy in Consumer Reports for added Peace of Mind. Excellent Team of Roofers. Thank You Antonio and Your Team for getting the job Done in one day and on budget."

"I have to commend these guys and the job they did with my roof. I had a partially collapsed roof from the snow and ice buildup on my roof. I needed the repair done urgently and withing budget. I got may quotes on the job with some outrageous bidding to be honest. Overstate gave me a fair price and told me exactly what needed to be done. Within a week the job was completed and my home is leakproof again."

Roofing questions, answered by experts

The terms “roof sealant” and “roof coating” are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof’s surface for waterproofing and UV protection. Products like roof caulk can also be called “roof sealant,” but the term is more commonly used for the protective coating.

If a roof is not vented, trapped air and moisture have nowhere to go and will cause moisture to build up in the attic. When moisture builds up, it can cause mold and mildew, leaks, and rot. It will make the space hot and stuffy, which can result in higher energy bills as the HVAC system works overtime to regulate the temperature.

The green coloration that develops on copper roofs is called a “patina,” and it’s a result of mild oxidation on the surface. The oxidation process is not harmful to your roof. In fact, the surface corrosion acts as a protective layer and won’t spread to the core of your copper roof materials. The discoloration will progress much more quickly in damp or humid climates than it will in dry climates. If you don’t like the green color, you can seal your roof to preserve the shiny, rose-gold look.

The lifespan of a torch down roof depends on the number of layers installed. A single-ply system typically lasts between 10 and 15 years, while a multi-layer system with two or three layers can last from 15 to 25 years. Although a multi-layer option may be more expensive upfront, it provides a longer service life. Warranties often reflect this, with about 12 years for a one-ply system and 15 years for a two-ply system. For context, this lifespan is shorter than other common roofing materials like wood or asphalt shingles, which typically last 20 to 30 years, with high-quality versions lasting up to 50 years.

You should avoid choosing a metal roof if your home has a weak structural support system, as metal roofs can be heavier than roofs made of other materials. If you're in a region prone to frequent hailstorms or high winds, you also need to be aware that denting may occur.
