On time. Professional and easy to work with.
Paragon did a fantastic job on our roof here in Portland. Would highly recommend them, and their team. Megan was very knowledgeable and easy to work with. Stayed within my budget and the crew cleaned up after the project was completed.
They were great! I made a appointment for them to come and check out the small leak I had. They were here on time, fixed my leak with out any issues! Cleaned up! Didn't even know they were there! Very respectful! I would definately use them again if I needed to.
Great experience, start to finish! Had the roof on our home and garage replaced and also two skylights installed. The staff was friendly, organized, on time and budget and cleanup was thorough. I’d recommend for sure! Thanks Paragon.

The finished product is stunning, and I couldn't be happier with how my roof turned out.
