Flat-To-Metal Conversions On SR 92
Hereford commercial roofing contractor for small commercial buildings along SR 92, including converting a worn flat roof to metal panels over retrofit framing.
Hereford is unincorporated and sits southeast of Sierra Vista along SR 92, near the Hereford Road crossing of the San Pedro River. Small offices, shops, and service buildings here often carry low-slope roofs that have been patched for years.
A metal retrofit adds light framing over the old roof to create slope, then new panels go on top. Rain runs off instead of sitting on a flat surface.
These conditions point toward a retrofit or replacement rather than another round of patches.
Owners who convert a patched flat roof to metal notice these differences once the work is done.
Most Hereford buildings land on one of these two paths after the inspection.

Metal roofs and retrofits
Where a retrofit is the wrong call, a new EPDM roof over a dry, repaired deck keeps the low-slope profile.

What To Have Ready
Five steps take a Hereford building from a patched flat roof to sloped metal panels.
Core cuts check for wet insulation, and the deck and walls are checked for the added load. Drains, scuppers, and curbs are mapped, since each needs a plan under the new framing.
Hereford is unincorporated, so the permit goes through Cochise County Building Safety. A retrofit adds structure, and the county asks for stamped plans when the scope calls for them, so the framing is designed before panels are ordered.
Wet sections are cut out and replaced, and the old surface is sealed. Framing goes only over a dry, solid roof, which keeps trapped moisture from rotting the deck later.
Rows of galvanized framing are fastened through to the structure to create slope. Panels, trim, and gutters follow, with clips or screws spaced closer at the edges for wind.
County inspections happen at the stages the permit lists. You get photos of the framing before it is covered, which helps with any future work on the roof.

Keep patching while leaks stay in one or two spots and core samples come back dry. Replace, or convert to metal, when leaks keep returning in new spots, wet insulation is widespread, or the membrane is brittle, shrinking, or blistered across the roof.
Isolated punctures, split seams, or failed flashing on a membrane that is still flexible point to repair. An infrared scan or core samples during the inspection settle it with evidence.
A retrofit builds light framing on top of an existing low-slope roof, then installs metal panels over it. The framing creates slope so water drains, and the space inside can hold new insulation. The old roof stays in place as long as it is dry and solid.
Most can, but it has to be confirmed. Framing and panels add load to the walls and roof structure, so the existing members are checked before anything is ordered. When the scope requires it, Cochise County asks for stamped plans, and an engineer signs off on the design.
They are closed off or rerouted. Once panels slope water to the eaves, interior drains no longer collect rain, so they are capped and sealed at the old surface. Gutters and downspouts at the eaves take over, sized for monsoon downpours.
Yes, and it is one of the better reasons to retrofit. The cavity between the old roof and the new panels has room for insulation, which helps offices and shops that run cooling much of the year. A vapor retarder is planned in so condensation stays off the panels.
Cochise County Building Safety, because Hereford is unincorporated. A metal retrofit adds structure, so expect plan review on top of the standard commercial permit, which applies to any commercial work valued at $1,000 or more.
Well, when the fastening matches the exposure. Clips or screws are spaced closer at the eaves, corners, and rakes, where uplift is strongest, and trim is fastened tightly so wind has nothing to catch. Loose fasteners are the usual leak source on metal after windy springs.
Commercial metal often lasts 40 years or more with routine care. Service life depends on fastener upkeep, finish condition, and how well the laps are sealed, since loose fasteners, scratched finish, and rust at laps are what shorten it in southern Arizona.
