"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."

"Working with Elite Work was enjoyable. We spoke with a number of roofing contractors and discovered that Elite Work has the most expertise and experience in installing solar panels as a roof replacement. Additionally, Ron and his staff performed a fantastic job. The replacement of the roof took two days. Additionally, new gutters and skylights were installed. A+ Recommendation!"

"If I could give A+ for each category, I would. MJA was highly recommended to me by a neighbor. I thank this woman every time I see her. Manuel, the owner of MJA, is one of the last of a breed of honest and conscientious contractors. His quote for a complete roof replacement was very, and I mean VERY reasonable. The work was done quickly and efficiently by a polite and hard working crew who left my property neat and tidy at the end of each working day. Even though he was managing several projects at the time, Manuel was on the site every day and working right beside his men. Our roof was extremely old, so there were a few surprises that added to the budget, but Manuel alerted us immediately and thought out of the box to give us the most cost-effective solutions. The final cost was still less than competitors' initial estimates. Don't hesitate to use this company. You will be in good, dependable, and trustworthy hands."

"Roof Systems is amazing ... they are the Superman of roofing. Our home sustained serious roof damage caused by a tropical wind storm. Roof Systems came out the same day to access the damage and then placed protection so our roof would not sustain more damage or create internal damage to our home. Their work is always done with pride and a high standard of perfection. They are always professional and friendly. I will only allow Roof Systems to handle our roofing needs."

Roofing FAQs, answered by experts

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

Shingle roofing can last anywhere from 15 to 50 years, depending on the type and quality of shingle, your local climate, and how well you maintain your roof. If you live in an area that sees extreme weather, like strong winds, hail storms, or hurricanes, the average life span of a shingle roof will often be on the shorter end, especially if you choose a more affordable roof shingle that isn’t designed to persist through extreme weather.

Sometimes. Professionals may be able to remove the old roof and re-attach it when completed, depending on your blueprints. That can help you save money. But this method is not without its risks. Larger roofs may crack during the transportation process. And if the roof is old or has problems, it may be better to replace it entirely. Keeping the old roof isn’t always possible if you are making significant alterations to the roofline.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

The best style of chimney cap for a brick chimney is one that fits tightly around the brick top of the chimney. The cap should have a screen to fully enclose it to keep animals out. The best materials include stainless steel, copper, or aluminum that fit tightly or are custom fabricated for a perfect fit on your chimney.
