We are a full service roofing company. Our focus is in residential and commercial roofing, We work with many manufacturers for all types of roofing from metal to asphalt shingles to all types of low slope roofing membranes. Additional phone - (508) 299-7663.
"Called On top roofing for an estimate, it took several weeks to get back to us, got the estimate and agreed to have the work done. A few guy showed up one day and started working, we were not notified they were coming to work,good thing we were here that day. They did the job and left without ever communicating with us about the work. We did a walk around and discovered that some of the work was not completed. So called the company back and the owner came out to look at the job, he said it would be about another $100. To complete. We were not happy because this was supposed to be in the estimate we agreed on. The workers show up again unannounced and did the job. We then received a bill for $200. More, again this was not what was agreed upon when talking to owner. We were hoping to form a relationship with this company for future work, but that's not going to happen, there was no communication and even with a written contract they will somehow charge you more than agreed on."

"5 stars for the window replacement. Everything about it, and all of the various people involved (sales, measurements, installation, inspection) were fantastic. The installation team did leave some debris on-site, but the inspector took it away in his truck before he left. 4 stars for the siding work (subcontracted). They did a good job on a 90+ degree day. They did use some of our bricks that were being used as an animal barrier for our garden to level their ladder and didn't put them back. We also had language barriers that made the signing off process a littler longer. Some random metal pieces from the job were left in our driveway and boarders, but were easy to find before they did any potential damage to car tires. 1 star for the insulation work (subcontracted). The guy was supposed to come between 7-9 am, but due to a "communication issue" on their side, he didn't come until 12:30 pm. My wife took off work to be home to let him in, and had they told us he would be there in the afternoon, I could've been home and no time off needed. Punctual is supposedly one of their bill of rights. We wanted a radiant barrier put on our roof. He did maybe 70% and stopped, calling the job done. He also left a bunch of the fasteners on the floor of our attic and didn't take the time to cut off any excess material. My wife signed off on the paperwork without looking at the job (partially her fault), but the installer had her sign it on the first floor and made it seem like he was in a hurry to get back to PA where he's from. I called and complained about the job and sent photos and video. It was the end of the day, and I missed the call back, but there was no communication after. Without letting us know, it turns out, they are coming tomorrow between 10-noon. I only found this out because I called to complain about the gutter installation that was late and asked about a follow-up to the attic install. ZERO communication that someone was going to be coming, so now I have to take off of work again in hopes that they actually show up. It's not listed on the app that they tout as the greatest thing ever. 1 star so far for the gutter installation (subcontracted). The gutter installation was supposed to be done on Tuesday (two days ago, and a day after the siding since it goes on top of a portion of that), but then the app mysteriously updated itself to say Thursday (today) between 8-10 am. This isn't a huge deal since it's outside and no one needs to be home, but again, no actual communication from Power. At 11:30, we noticed that no one had shown up, so I called. It turns out, the install team couldn't source the black gutter materials, and so they'll have to do it tomorrow. ZERO communication from Power until I called them. The app even shows that they're still coming today between 8-10 even after I called and complained. It's supposed to rain today/tomorrow, and the manager assured me that it wouldn't do any damage to the siding that we just had them install. They have 10 bill of rights. They can go ahead and take off customer first, allocation, and punctual based on their descriptions. If you need windows done, I highly recommend them. When they try to sell you on other stuff, find someone else."

"I had a FANTASTIC experience with LCT! It started with a prompt response from them, setting up an appointment the next day after a tree fell on my house. James came down and explained everything thoroughly and gave me some options. After talking to a few other vendors, I knew I wanted to go with LCT. Their pricing was better than the other quotes and James was great to work with. Before the crew started any work I met the owner, Luis, and knew I had chosen the right company. He was just as great as James, very thorough and let me know what would be happening. In addition to needing the roof replaced we also had some damage to rafters and decking to replace. After the job was complete, Luis did a thorough inspection of the work and made sure I was happy with everything. The crew did an amazing job and I couldn't be happier with the work. The office staff was also great to work with! I got to meet them when I went down to pay the invoice. A 5 star experience from start to finish. Thank you LCT!"

Roof sealant applications FAQs
A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing.
You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.
A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
