Working safely on roofs is essential for commercial roofing contractors to prevent falls and injuries. Proper safety equipment, including harnesses, safety lines, and non-slip footwear, must be worn at all times. Workers should also be trained on how to properly use equipment and navigate the roof terrain. Regular safety inspections and hazard assessments should be conducted to identify and address potential safety risks.

“Outstanding Work”
“In my 40 years, I’ve rarely had the opportunity to work with a hands-on owner like Joe Calderon. His integrity and commitment to the success of his company and in particular the Beaverton Public Safety Center was outstanding.”
