"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 least suitable roof for solar panels is a wood shake roof. An electrical mishap with your solar panels could start a fire on the roof, so some areas don’t allow solar panels on wood roofs. You don’t have to let a wood roof stop you from going solar. You can replace your wood shakes with shingles. Installing the panels on the ground is another option.

Asphalt shingles have varying thicknesses across the length, so failing to stagger shingles from one row to the next will leave you with bulges and bumps if the thicker sections stack on top of each other. Not only is this unappealing, but it increases the risk of water intrusion. Stagger each new row by 6 inches to avoid this issue.

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.

Yes, it’s possible to replace drip edge flashing without removing shingles, but it’s not a good idea. You’ll have to lift the bottom shingles up to remove the old drip edge, install the new material, and then lay the lifted roofing material over the new drip edge. Bending roof shingles can cause damage, and if you have ongoing issues with roof leaks that prompt drip edge replacement, it’s a good idea to consider a roof and drip edge replacement to avoid ongoing issues.

No, you should not close or cover your gable vents in the winter. While it might seem logical to block cold air, heating your home creates hot air that rises and can cause condensation in the attic. If the vents are covered, this moisture becomes trapped, creating an ideal environment for mold and mildew. Keeping the gable vents open ensures proper ventilation, which helps dry out the attic, maintain even temperatures, and prevent moisture-related damage.
