Unfortunately, Quintanas Brothers left a massive mess behind after installing our roof including dangerous and toxic materials of several rusted nails, screws, staples, sharply cut metal pieces and tons of roofing material, which is often petroleum based. I spent hours picking up these items from our yard, patios and driveways. I’m sure I still missed some but I hope I dont have to sue Quintanas Brothers if a family member or pet steps on something sharp. It’s industry standard to lay down tarps around the home and then pick everything up and they did not do this.

The Quintana Brothers just finished putting a new roof on my house today and I couldn’t be happier with the work. They show up on-time and go to work with gusto. They work and get it done. Everything we needed was done right and on time. I can’t recommend them enough.

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 7 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 7, of which 6 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
There is not much data on Quintanas Brothers & Associates. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
