"Came out to give us an estimate was very reasonable we we're excited to get this done. We had a project set for Dec 4th so we had out door delivered the 3rd. My husband texted him to make sure everything was set and see what time he was coming only to find out that he cannot do our job until after January , if we would have known we would have waited on the door (now we have to store). I just wonder if he was going to tell us he wasn't coming if my husband hadn't texted him."

"After I submitted the project, George called me within a few hours. He scheduled an appointment — an actual time, not a range — the next day and arrived on time. He reviewed the proposed work with me, pointing out various aspects of it that aligned with another proposed contractor. He then gave me an official written quote on the spot. It was lower than quotes, and it was for a definite amount, again, not a range. The foreman came by the next day to get the specifics so he could buy the necessary materials, and work commenced that afternoon. The project took three days, slightly under what they anticipated. The team arrived and left on time, and the areas were tidied up each time. They were also professional and friendly. Unfortunately, they discovered something that had not been done during the home’s original renovation, which George and Jim discussed with me. It was beyond what I wanted to do at the time, but we were able to settle on something that they thought would get the job done and I could agree to. They were excellent at explaining various aspects of the job like this, and I felt comfortable with their recommendations. They also accomplished additional two small tasks, one of which I mentioned I needed to do at a future date, and one that they observed. Both were done under the original agreement, which I appreciated. I definitely plan to use Louise August (a family business) for any projects that arise within their areas of expertise because it was a very good experience."

"I have used National Roofing before for a roof leak. They are a bit higher priced than other companies I have used but what you get for the additional cost is great quality and service. Robert Martin is very responsive to email and texts. This time I had a minor leak in my outdoor porch ceiling and decided it was time to fix that part of my roof (a flat roof and part of a pitched roof). The roof repair went well and it happened fairly quickly but about 2-3 weeks later I noticed rotted wood under part of the new roof. I texted Robert on a Saturday afternoon and he called me back less than 1 hour later. I wasn't expected such a prompt response. And honestly, another roofer might have taken his time to get back to me. Even though it turned out that the leak was not caused by the work they did- and it required taking off part of the new roof to get to the damaged wood, Robert did the work quickly and he did not charge me. The ceiling is painted bead board and I was concerned that the part they were going to fix wouldn't match what was already there. Robert talked me through what he was going to do. The finished work looks great- like nothing happened. I offered to pay and he refused. That is the kind of person he is."

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.
