These people are not only careless, but also do not bother to respond. Their workers thrashed my and my neighbors plants, moved things around without permission and when I contacted them instead of this review, they didn't even bother to respond. If you want to hire a company that has zero respect for people around them, and upset your neighbors, be my guest; however, people who are disrespectful and unprofessional to others will also do the same to you.

Clow Roofing & Siding did a roof repair on my roof in 2017, installed some new flashing and shingles. I now have water leaking into my attic at the location of their repair. Mold and dry rot that stinks up my sons bedroom. When I called to ask them about their warranty, they said they would look into it and call me back. Crickets. I don't recommend Clow Roofing & Siding.

Had a new roof installed and gutters replaced by Clow Roofing. They did an excellent job while also using quality materials. Very competitive pricing as well. Doug Baker was easy to communicate with and was great to work with.

Justin and David showed up on time and installed 6 skylights and 3 vents into my existing roof. They were professional, polite, and did great work. They communicated well and cleaned up prior to completion. The price was fair as well. If I need Roofing or Siding work in the future I will call them back.

This is all pre-COVID by about a year. Clow is the worst. The guy who gave the bid was nice to work with and very capable. After that it was a drag. We waited months to get the actual work done and could not get a call back no matter how many messages I left. When we did get the work done, the roof vent installation was sloppy, the flashing was badly tied into the existing structure and the off cuts were left on the roofing membrane! To top it off I found a pair of rusty tin snips on the membrane as well which is an indicator of how thorough that final inspection was.
