"Let me start by saying that I received 4 estimates for my roof repair and installation, and Euro Construction Group was not the cheapest. But price shouldn't be the only factor when considering what company to go with on an important project like a roof replacement. When Matt Siwik came to my home, he spent over an hour inspecting every square foot of my roof as well as a problem chimney flashing area. Two of the other three companies that showed up never even went up on the roof, and the 3rd ignored the chimney issue altogether. Matt explained just how he planned to deal with the chimney and roof installation and gave me options on what the best methods would be. He gave me confidence that he and his company knew what they were doing and the decision to go with them was easy. Matt showed up a day before installation and supervised the delivery of supplies and also began some preliminary work on that problem chimney. The very next day Matt arrived with his crew of 7 promptly at 7:00AM. And just when I thought it couldn't get better, he introduced me to his crew."

"We met first with Sam who was upfront about what needed to be done and wrote the contract the way we wanted so that there would be no surprises during the installation. Sam provided some additional carpentry work and guaranteed the price even if there was additional work needed. The crew arrived as promised at 8 am on Monday. They were incredible! By nightfall, they had removed both layers of roofing, installed all-new plywood decking, repaired rafters, added roof supports, and completed the project including clean-up. We were impressed with Nick and Donny who supervised the project. Sam kept in touch with us throughout the day. The next day they sent Miguel who vacuumed the attic and did some additional work. So far, I haven't found one nail or scrap on the property, which was well-protected during the project. We interviewed 5 roofing companies and hoped we selected the right one - and we did. They did a quality job and provided an excellent warranty and judging from our experience so far they will respond quickly if there are any problems, which cannot be said for many companies doing this work. The final price was exactly what we signed up for, with no hassles. I highly recommend them."

"Raul did a great job, he went above and beyond to repair my roof post storm to ensure a water proof membrane. He also went out of his way to clean the gutters and ensure they were all secure. Would recommend to a friend, in fact I did."

"Myself and my father has used MJA Contracting for two roofs in our houses in Jersey City. Both times Manuel and his team has taken good care of us and installed good roofs. At first I thought the price was a bit high but after I saw the amount of time, material, and workmanship that they completed I thought the price was very fair. Roofs are alot of work as I learned. What I especially liked about Manuel is he did not go cheap and install a torch down rubber roof. He installed a rubber EPDM roof instead. If you have a flat roof, do yourself a favor and install a rubber EPDM membrane and make sure to contact Manuel. He also rebuilt our chimneys very good as well. Excellent masons! I guarantee you will not be disappointed!"

Roofing FAQs, answered by experts

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

If your roof has a vapor barrier, you will need approximately one square foot of roof vent for every 300 square feet of ceiling space. If there is no vapor barrier, the roof should have one square foot of roof vent for every 150 square feet of ceiling space. If you are not comfortable making this determination, a local roofing professional can help.

The short answer is, yes, cedar shakes do last longer than asphalt shingles. But the long answer is, it depends on maintenance. Asphalt shingles last about 20 years, while cedar shingles typically last about 30 years with proper maintenance. If they are very well maintained and installed in an area with a mild, drier climate, they can last up to 50 years.

You can replace a roof in the winter, though it’s not the most popular time to do so. The biggest drawback of winter roofing work is the weather. Snow and ice make for dangerous, slippery working conditions. Plus, shingles can only be installed in temperatures above 40 to 45 degrees. 

The best time to replace a roof is in the spring or fall when the weather is mild. However, you can likely save some money by booking the job in the winter off-season, when roofers have more availability. 

If you're looking for a dependable and affordable option for garage roofing, asphalt shingles offer a durable way to blend a detached garage in with the surrounding residential aesthetic. If you're looking for a more durable and protective option because you're storing expensive equipment in your garage, consider metal roofs that perform well against snow, ice, hail, and heavy rains.
