Q: Which is the best membrane for flat roofs?

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Q: Is rubber roofing an environmentally friendly option?

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.

"I received 8 competitive bids for a full roof replacement on our 1901 Victorian B&B. We chose Exterior Solutions LLC, whose bid was 28% below the average. The 4,000 sq ft project included removing 35-year-old asphalt shingles, installing all new plywood sheathing, and updating roof venting. The roof has over 45 facets with a predominant pitch of 10/12, making it a challenging job. John A. and his team did an outstanding job installing CertainTeed Landmark Pro shingles. John scheduled the work while our B&B was closed and ensured the roof was sealed before any rain. He worked closely with our neighbors to minimize disruptions. Cleanup was exceptional—nothing left behind. We’re extremely pleased with the quality, professionalism, and communication throughout. Highly recommend Exterior Solutions LLC for any roofing project."

"I hired this company from a list provided by Angi. I was looking for someone to repair my concrete, painted driveway. They first wanted to replace the driveway, but their price for that was $49,000. The only alternative they offered was to patch over the cracks and spalling on the existing concrete, and then repaint. That price was $8900, so I went with that option, with the understanding that they couldn't guarantee how well the patching would hold through the winter. I hired them based on their 5-star rating on the Angi list. They did an OK job with the patching, but there are two big problems with their paint job: 1) they didn't wait long enough to allow the patching to dry, so after two weeks the paint buckled over the patching, and 2) they didn't use a separate primer, so the paint didn't adhere well and peeled up in several places. I've called them several times. They keep promising to come back and fix these areas as a "courtesy", but they never show up."

"Unprofessional visit. Showed up unannounced and we only knew they were there because one person stood 10 feet from our porch staring at us in through our living room window. My wife spent 10 minutes talking to them, they stated they had no business cards, they only had an appointment card but didn't present it. Honestly when you show up at someone's house you need some sort of identifier if your walking door to door in casual clothes. After the uncomfortable dead stare through the windows my wife and i have decided to post a No Solicitors sign. They didn't take no for an answer at first, pushing with more questions to circumvent the no she gave, as well as interrupted our dinner, as they showed up right at 6pm."

"Extremely disappointed with this company. They do not stand by their guarantees. Did install shower in one day. Was not provided with the shower head I ordered. Calking and trim work was very sloppy. Went through the shower wall into my bedroom, did sparkle wall and left it. Shower doors have leaked and was finally told six months later that there is nothing they can do to correct the issue. Originally quoted $24,000.00 for the walk on shower, eventually agreed to $11,500.00. Completely dissatisfied with my shower. Once they get their payment, they are done."
