Josh Richmond review about company A Larsson & Sons Roofing

A. Larsson and Sons installed my asphalt shingle roof in 2012. They also improperly installed the dryer vent. It was misaligned with the decking so they didn't even try to connect it. Instead, they let the humidity and flammable lint vent directly into the attic space! Under the permit, they failed an inspection on the flashing and another on the final inspection before getting a pass. Four years later and there's a leak at the flashing. They either ignore my calls or promise to call me back. They don't even have a physical address so I guess I'm out of luck.
