Signs Your Commercial Building Needs a Re-Roof
Persistent Membrane Blisters and/or Wrinkles:
When a flat roof membrane wrinkles, it can prevent proper drainage and place stress on seams, increasing the risk of water intrusion.
Loss of Granules:
Granules protect the membrane from UV and weather; significant loss typically indicates the roof is aging and nearing the end of its lifespan.
Faulty Equipment Seals:
Worn seals, loose flashing, or failed curbs around rooftop HVAC equipment and skylights can allow water to spread beneath the membrane.
Clogged Roof Drains:
Debris buildup prevents proper runoff, causing water to pool. This standing water increases pressure on seams, flashing, and penetrations.
Ponding Water:
Depressions in a flat roof trap water, accelerating membrane wear and leading to leaks.

REVIEWS
WHAT OUR CLIENTS ARE SAYING
Tim and Brandon sent updates at every step including pictures of their work in real time.
We are very pleased and have contracted them for another property.
Highly recommend.
The price was great (as much as it can be for a roof, no small purchase), and the crew was really fantastic. They were professional and got the work done quickly. They had to put sheathing on my roof, since it’s old and didn’t have any underneath (!), and the whole project still only took 4 days.
For me, the best thing was that the crew cleaned up every day. The yard was clear, and there were no nails or debris hanging around. It’s a little thing that was really nice to see— it was really nice to go outside in the afternoon and not worry about stepping on anything/ having that peace to move around in the middle of a project.
I’d recommend this company to anyone.
This company is a class act and I am so pleased to have picked GreatWay Roofing who kept me informed thru email and sent photos as the project was moving ahead.
Great customer service, knowledgeable courteous workers and a satisfied customer says it all
