We wanted to replace our roof before we installed a solar system and Q7 did an amazing job on a very steep pitched roof. There was a small area where the sheeting on the roof appeared to be sagging, I brought this to their attention and they addressed the problem without hesitation and did a great job correcting the issue. The new roof looks amazing, they even painted the vent boots to match the roof.

We had a leak in our roof after the last big storm. I called a few companies and Q7 was very quick to respond. Alfredo came out to look at the leak a couple of days later and we were scheduled for the repair the following week. The work was done quickly and in a timely manner without any issues. We even asked them to come back and paint a tiny strip of metal that was showing, and that was done quickly as well. We also replaced our existing skylight and were given a good price for it.I very much appreciate the speed with which everything was done as well as the quality of the work carried out. Their price was very competitive and Alfredo is easy to work with. I always appreciate when my phone gets answered and that was the case with Alfredo.I definitely recommend this company! Thanks Q7!!

My roof began leaking in the last storm and I had no idea who to call. I did a little research and found Q7 Roofing and Waterproofing. I emailed them and two other companies that I was referred to. Q7 got back to me fast. Alfredo came out and gave me an estimate and the repair was done in a week. I am now looking forward to having install a new roof in Spring. A great experience. Friendly people. Efficient, reliable, and nice. Also a very fair price.

We put off replacing our decades old roof for years fearing the project would be horrific. If we had known of Q7 Roofing & Waterproofing Inc. sooner, we would not have waited so long.Our roof project finished up a few days ago in a timely manner and to a level beyond our expectations. If you are reading this and hesitant like we were, dont put it off, consider getting on Q7s schedule. We had several requests unique to our home and Q7 delivered on those. We are detail-oriented people and handy ourselves, so we seek high quality workmanship.Q7 Roofing & Waterproofing Inc:ogood listeners, good communicatorsonot the low bidder, not the high bidderoa family business with dedicated, easy-to-work-with peopleovery hard workersohad female roofer(s) employed; non-sexist hiring practicedoprofessional and honest management team and ownersQ7 Roofing Team:oindustrious despite unusually high summer tempsocleaned up property and supplies at the end of each dayohad a commendable comradery i.e. no yelling at each other nor dramaOur Management Team: Benjamin, Carlos, and Vicenteoimpressed by individual styles, skill sets, and contributionsoone or more present each day resulting in goodcommunication and oversightoall city inspections approved at first passodelivered on sealing roof openings from squirrel/critter accessoensured attic was cleaned up of debris properlyoimpressed even more on the last day when small finishing details needed completion and managing (pleasing customers is likely harder than city inspectors)Q7 Owners: Geo and Cesar.

We also trust if anything were to happen in upcoming years Q7 would step up to fix the problem.We highly and proudly recommend Q7 Roofing and Waterproofing Inc. based on both their workmanship and our experience with them.

We had a leak on our 2nd floor deck. Q7 Roofing replaced and water proofed our deck. We worked with Alfredo (he's the representative for the project) to get the deck done. We appreciate his responsiveness to our requests.
