Commercial Metal Roofing, at a glance
Commercial metal roofing covers standing seam panels, metal retrofit over existing roofs, and the metal accents on churches, schools and municipal buildings. It runs long, sheds water fast and lasts decades when the fasteners and seams are specified right. John Beal Roofing installs and repairs commercial metal across St. Louis. Call (314) 429-6000.
The Short Version
Whether This System Fits Your Building
Service life
30 to 50 years for the panel, with coatings and fasteners as the shorter-lived parts.
What to watch
Fastener backout and oil-canning at the panel ends, plus every penetration cut after the original install.
Installation
Where These Roofs Actually Fail
Membrane failures are almost never in the middle of the sheet. They start at the details — the curb flashing, the pipe boot, the wall termination, the drain.
That is why we spend the time on the parts nobody photographs. A field seam takes minutes; a properly rebuilt curb takes an afternoon and it is what decides whether the roof makes twenty years.
We also register the manufacturer warranty on your building, so the coverage exists in writing under your address rather than in a folder somewhere.

Common Questions
How long will this roof last in St. Louis?
30 to 50 years for the panel, with coatings and fasteners as the shorter-lived parts. Our freeze-thaw cycles and summer heat are hard on any membrane, so the install details and a twice-yearly inspection matter as much as the material.
Can we recover over the existing roof instead of tearing off?
Sometimes. If the substrate is dry and the deck is sound, a recover saves real money. If a moisture scan shows wet insulation, tearing off is the only honest answer.
Do you install this system yourselves?
Yes. Our own crews do the work, and we hold manufacturer certifications for the systems we install, which is what makes the full system warranty available.
What does a repair on this system cost versus replacement?
A localized repair is a fraction of a replacement, and on a roof with remaining life it is the right call. We will tell you which one your roof is — with photos.
How disruptive is the installation?
Low-slope work happens on the roof, not inside the building. We coordinate hot work, odor and noise windows with the tenants or residents before we mobilize.
