Flat and Low-Slope Roofing questions
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.
Do I need to be home?
Not for the roof work. We'd like you there at the walkthrough at the end so we can go over what we did and you can look at it with us.
How far out do you travel?
The whole St. Louis metro on both sides of the river, from St. Charles County out to Jefferson County and across into Madison and St. Clair County in Illinois. Offices in Maryland Heights, Chesterfield, Festus and Edwardsville.
