Didn’t need a new roof, we just moved in a year ago and have approx a 15 yr old roof. Had a small repaired done. Wanted to change the roof color, but not bad enough to spend $40,000 or more based on quotes we received from others to re-roof. Found roof scientist, talked through their process, got a quote and got booked. Dale and Luke came the day before the coating installation to wash the roof, the next day they and a couple others showed up at 7:30 am for prep of tarping off areas then sprayed their product on the roof. This gives us 30+ yrs more life to the roof and we were able to change the color from brown to black. Very pleased with the results. Would recommend as a great alternative to replacing the roof. The photo shows the new black and the old brown.
