Why Granite City roofs fail the way they do
Flat and low-slope commercial membrane, multi-layer residential tear-offs, galvanized gutters, chimney and parapet masonry. Those aren't random; they follow directly from dense working-class housing from the 1910s through 1950s, plus industrial and commercial flat roofs.
And because industrial corridor storms with wind-driven rain that finds every open seam, a small unaddressed problem in Granite City tends to become a large one in one afternoon.

Commercial roofing in Granite City - common questions
Do you offer financing?
We do, and we'll walk through the options with you when we give you the estimate. Plenty of roofs get replaced because the alternative is interior damage that costs more than the roof.
How soon can you start?
Emergency work gets same-day attention when we can manage it. Scheduled work depends on the season - after a hail event the whole metro calls at once, and we're honest about the queue instead of promising a date we'll miss.
Will insurance pay for this?
If the damage came from a dated storm event, usually yes. Wear and age, no. We'll tell you which one you have after we look, and we'll document it either way.
Are your crews employees or subcontractors?
Our own crews. The person on your roof works for John Beal Roofing, which is why we can put a lifetime workmanship warranty behind the job.
What happens to my yard and landscaping?
We tarp what needs tarping, keep debris out of the beds, and run a magnet over the yard and driveway before we leave. Nails in a tire is the fastest way to lose a customer.
