"I am a 69 year old female. I am beyond grateful for Rafael and his company, AMJ Contractors. He went above and beyond!! When I noticed my ceilings and walls were bowing, Total panic. Saturday, I put out a general request for quotes. Rafael Jimenez, the proud owner of AMJ Contractors was the first to respond and here within the hour. I explained my current financial situation and if only the absolute bare minimum be done. Before he went on the roof, I asked if he knew anyone in need of a huge air conditioner. I needed it out so I could put my new little one in. As I walked him to his truck. He looked at me and said, if you are available on Monday, I’ll come back with a helper. Only pay me for the roof supplies. I will fix your roof and put in your 3 air conditioners. I was stunned Tears flowed Two days later, My 3 air conditioners were installed with thick plywood from his shop. Next on my roof for hours with big smiles!! A true family man Top notch job Highly recommended"

"I recently hired Great Group Roofing and couldn?t be happier with the experience. From the initial estimate to the completed roof installation, the team was professional, punctual, and highly skilled. They kept the worksite clean, communicated clearly throughout the project, and completed the job on schedule. The quality of workmanship exceeded my expectations, and my new roof looks fantastic. If you?re looking for a reliable roofing company that delivers excellent service and quality results, I highly recommend Great Group Roofing!"

Pam and Brant, both local in South Jersey, saw how often homeowners struggled with aging roofs and expensive replacements. Pam’s work in real estate and Brant’s experience in sales showed them the real benefits of Roof Maxx’s shingle restoration.\n\n In 2024, they brought Roof Maxx to South Jersey and have since helped hundreds of homeowners extend their roof’s life and save thousands. As local owners, they’re committed to honest guidance and real results for their community.

Roofing questions, answered by experts

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

Yes, gable vents can let water in. That being said, this usually only occurs during extreme conditions like heavy rainfall. You can prevent water from entering through gable vents by adding a screen that traps the water before it can enter.

The best way to prevent wind damage to your roof, especially if you live in an area prone to hurricanes, tropical storms, or tornadoes, is to invest in a roofing product with high wind resistance. Look for the ASTM D3161 and ASTM D7158 ratings to see the specific wind speeds your roofing product can withstand. Impact-resistant shingles have the highest wind resistance ratings and will give you the best chance of avoiding wind damage.

The best kind of tarp for a roof is one that will stand up to the elements, weather, and sun. Viny roof tarps are known for their durability and resistance to water, tears, and mold—making these tarps a good choice for use in winter conditions and the summer sun. Polyethylene tarps are also quite durable and waterproof.

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.
