Quality is our Goal, we are a locally owned and operated company that values honesty and integrity and stands behind our work. We specialize in repairing and installing all styles of roofs and gutters as well of Tuckpointing and waterproofing. And Our services are customized to the individual project, paying close attention to the details of each project that we're involved with. We look forward to building long-term relationships with our clients and guarantee your satisfaction!

"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."

"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."

"I had a great experience with this company. I had a major roof leak on flat roof in wash dc. They came the next day, assessed, the very next day they came back and repaired my roof. The price was very reasonable. I would highly recommend this company. I also had my gutter replaced. Again the price was reasonable and they did an outstanding job."

Roof sealant applications FAQs

Flat roofs should generally be recoated every three to five years, depending on the climate. Since they don’t have a slope to help them avoid rain and sunlight, they wear out more quickly than a pitched roof.

If you have an EPDM rubber roof, it likely resists weather damage already and shouldn’t ever need to be recoated. Many roof coatings don’t work on EPDM roofs either, so make sure to double-check with the manufacturer before applying any. If your EPDM roof starts to leak, you’ll usually have to apply a new layer instead of resealing it.

Most homeowners insurance policies only cover roof damage caused by single, specific events, such as fires, stormy weather, or falling trees. Homeowners insurance usually doesn’t cover roof coating or sealing since these are routine repair jobs that come with normal wear and tear.
