"Ignored directions. I have outside dogs that are not friendly. I told them to text me before arriving so I can put them inside and he didn't. Ignored driving directions. I have a split driveway and told him to stay to the right. Instead, they drove up on a dirt road I didn't want them to use. Rescheduled my job and didn't tell me until 5pm that night. I spent all day waiting, putting off my errands. I texted and was told the crew was coming that day. He wasted my entire day. Crew left before I could inspect the job and they did it wrong. Didn't install correctly. Didn't put the boot back on the end of the downspout, didn't put back leaf filters, and failed to properly secure downspout to the house. "

"One of the worst companies I have EVER dealt with in my life. Nothing but runaround, lies, and lack of accountability. They will tell you something over the phone, then when you follow-up, they will magically lose all records of prior conversations. I was told replacement windows would be ordered in June 2024 - never ordered. In January, ordered correctly with 4-6 week expedited delivery time quoted. Now in Feb, was told the windows would not be ready until end of March (total of nearly 11 weeks since order). Magically, they have no record of quoting me 4-6 weeks, though I have email records saying otherwise. Just a miserable company to do business with, would never recommend to any homeowner."

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.
