Oregon Roof Consulting recently received an official notice from the State of Washington that was sent to all licensed roofers in Washington regarding widespread improper underlayment installation on low slope roofs. This is a nice start. Now, along with Oregon they need to send similar notices regarding proper fastening, proper installation of vents/pipe jacks and other protrusion fixtures, chimney & skylite flashing, proper perimeter and valley flashing installation, etc.
