By Greg R.June 5, 2020
Very poor workmanship, failure to get permits or follow requirements for inspections.
Very slow to return for warranty issues.
Shingle manufacturer would not warranty roof due to workmanship.
Was told they were going to remove, and replace 50 to 60 percent of the 3000 sq ft that was installed, but only 12 bundles of shingles were delivered for replacement.
Was advised to file a civil suit, but would only get the 12000 bond money... Paid 20000 for this roof in February 2020

We knew when we were going to get our roof done, we would be using Preferred Roof Services. They are local, family owned and ran and take pride in their craft. This house’s roof was 34 years old as were the gutters and we were dealing with a very difficult HOA that demanded one specific brand and type of shingle to replace the cedar shake. They took extra care and built covers over all of my garden boxes and water features. They made sure they picked up all scraps and residual material. The pride they took in the entire project was worth its weight in gold. They even had an excellent gutter referral and suggested that black gutters would really complete the appearance. Our home, in Gem Heights, originally was the model home when it was built in 1987. It’s definitely a catch with the new roof! Thanks Preferred Roof Services!
