More about John Beal Roofing

How we do flat roofing

The scope, plainly: single-ply TPO and PVC membrane, modified bitumen where heat welding is impractical, tapered insulation to move water, and heat-welded seams with proper terminations at every edge and curb.

Everything gets installed to manufacturer specification, because that's what keeps the material warranty valid. Shortcuts on nailing pattern or underlayment void coverage, and the homeowner is the one who finds out years later.

St. Louis specifics

ZIPs 63104, 63110, 63116, 63118, 63139, in City of St. Louis. Housing is brick two-flats, gabled four-families and turn-of-the-century townhouses, most built 1890 to 1930, so flat roofing here means low-slope rear additions that were never flashed right more often than not.

Storm exposure: straight-line wind funneling between tall brick rows, and hail that strips granules off south-facing slopes first. We document it accordingly.

Flat roofing in St. Louis - common questions

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.

Do you actually cover St. Louis?

Yes - St. Louis is regular territory for us.

What warranty comes with it?

A lifetime workmanship warranty from us, plus whatever the manufacturer covers on the materials. Being an Owens Corning Platinum Preferred Contractor lets us write their stronger system warranties, which most contractors can't.
