They came out and inspected the roof, found and explained several issues I was unaware of, like an improperly installed bathroom vent that was dumping directly into the attic. They took the time to fix old issues and do everything correctly. He gave me several great options to choose from and even matched the vents. The roof got done quickly and on time, and they did a great job cleaning everything up, I didn't find a single nail or anything anywhere. They were honest, great to work with, and I would highly recommend their services.

I actually had a small repair I needed done in a VERY timely manor, Sieren Roofing went up and beyond to take care this. Communication was A+, documentation was more that expected. Quality work! and they worked late to get it done. Would highly recommend

The service was amazing! From the first call to the visit. They were prompt and very knowledgeable. The issue was taken care of immediately. There was no pushy sales to replace the roof. When it's time for a roof, I will definitely be calling Sieren!

Sieren roofing Came out and inspected our administrative buildings roof, explained everything thoroughly and provided pictures. They offered three different quotes to choose from and explained what each quote offered. Out of 4 different roofing companies, we chose sieren. I’m glad we did. They were very professional and communication was great. The roof looks amazing. The owner also took time to look at the gutters and siding, hopefully we will be doing business with them in the near future.

Bob at Sieren Roofing was great to work with. He came out and gave us an estimate and had it replaced it in a very timely manner! We had damage from a storm and he got to it before the next big rain! I would definitely recommend them.

It can provide aerial photos and video, measurements and a roof condition report, with images of hard-to-reach areas and less foot traffic on the roof.

Can Gaco silicone coatings be applied to asphalt shingles?

The company describes Gaco's silicone formula as suitable for most roof types except asphalt shingles.

What does the workmanship guarantee cover?

Sieren says it will repair leaks caused by its workmanship at no cost for as long as the customer owns the property.
