Steer clear - terrible workmanship
We are worse of than before we paid them for a new roof. J&J's new roof has had three major leaks in as many months due to either dumb mistakes or malice - repeatedly destroying newly completed renovations. Roof has been more than half covered by tarps through much of the winter, often causing snow and ice to slide off suddenly, potentially injuring anyone going in or out of the house. Has caused much lost sleep due to noise of tarps in wind, and wondering where next leak might be. J&J wont own up and take responsibility for poor quality work, and keeps blaming new windows for the leaks (no windows in our attic). Do yourself a favor and stay away from this company unless you want your house slowly wrecked from the top down.
-UPDATE- After a lot of fighting and more leaks discovered, we had an independent building envelope specialist company examine the roof - the report confirmed our worst fears, and recommended complete roof replacement. We took J&J to court, won and received a settlement. Got a different company to come out and replace the entire roof, and it's been great. Again, cannot stress enough to avoid J&J Roofing.
