Is This Building a Fit for a New Metal Roof?
A Florence commercial metal roofing contractor matches the panel to the slope and the building. These lists show when new panels make sense and when the existing roof should be repaired first.
New Metal Fits When
- The roof has enough pitch for the chosen panel and seam
- Old panels are rusted through along eaves and end laps
- A leaking flat roof can take retrofit framing
- Interior drains have leaked for years
- The owner wants concealed fasteners on a public-facing building
Repair Existing Panels When
- Leaks come from screws, washers, or lap sealant
- One or two panels are dented or holed
- Curb and wall flashing has loosened
- Gutters and valleys are packed with debris
- Rust spots are surface-deep and caught early
What a Florence Commercial Metal Roofing Contractor Looks For
Metal roofs tell you where they leak. The chip on each condition shows how soon it needs attention.
- Repair First
Backed-Out or Rusted Screws
Heat cycling walks screws out and dries washers until they crack. Fastener rows near the eave, ridge, and end laps go first.
- Repair First
Leaking Side and End Laps
Old sealant shrinks and lets wind-driven rain past the lap. The fix is scraping it out, adding stitch screws, and resealing with butyl tape.
- Watch
Scratches and Surface Rust
Scratches from foot traffic or hail let rust start at bare steel. Touching them up early keeps the spots from spreading under the paint.
- Repair First
Packed Gutters and Valleys
Leaves and grit hold water against the steel and overflow into the wall. Clear gutters and downspouts keep that water moving.
- Watch
Dripping on Cold Mornings
Condensation forms when warm, humid air meets cold panels over thin or missing insulation. It looks like a leak but needs a vapor retarder fix.
- Call Now
Lifted Trim and Ridge Cap
Wind peels loose closures, trim, and ridge cap first. Refastening them before the next storm keeps a panel edge from lifting.
Why Florence Owners Invest in Commercial Metal Roofing
A well-built metal roof pays back on the roof, inside the building, and in maintenance planning.
On The Roof
Panels Matched to the Slope
Standing seam clips let panels slide with heat, while R-panel suits steeper shop and barn roofs that shed water fast.
Finish That Matches
Ridge cap, eave trim, and gutters in the same finish as the panels age together instead of rusting at the edges.
Inside The Building
Less Condensation Drip
Faced blanket insulation with a sealed vapor retarder keeps humid air off cold steel in shops and warehouses.
Interior Drains Retired
Retrofit framing over a flat roof sends water to new gutters, ending leaks at old interior drains.
For Planning And Budget
A Simple Upkeep Routine
Spring and fall walks check fastener rows, gutters, curbs, and trim, which keeps repairs small and predictable.
Finish Choices by Budget
PVDF paint holds color longer, SMP costs less, and Galvalume steel carries an alloy layer that resists rust.
Commercial Metal Roofing Options for Florence Buildings
Two panel types cover most commercial metal roofs. They differ in how they attach and where they leak.
| Factor | Standing Seam | R-Panel or PBR |
|---|---|---|
| Attachment | Concealed clips under raised seams | Screws through the panel face |
| Panel movement | Slides on clips with heat | Held tight by fasteners |
| Slope | Lower slopes allowed with the right seam | Needs more pitch to shed water |
| Leak points | Seam ends, ridge, penetrations | Screw washers, side laps, end laps |
| Usual buildings | Offices, schools, churches, retail | Shops, barns, warehouses, plants |
Each manufacturer sets the slope limit for its own panel and seam profile.

The steps on a new metal roof, a retrofit over a flat roof, or a major repair.
1
Inspect Your Roof
Every fastener row, lap, curb, and gutter is checked, and panel profile and gauge are measured. Inside, the insulation facing and the underside of the steel show condensation or rust.
2
Choose Panel And Finish
Slope, building use, and budget set standing seam or R-panel, 24 or 26 gauge, and a PVDF or SMP finish. Ammonia exposure in animal buildings calls for an approved finish.
3
Frame Or Prepare
For a retrofit, light-gauge purlins and sub-framing are set over the old flat roof after an engineer checks the load. For a reroof, old panels and fasteners come off in sections.
4
Set Panels And Trim
Insulation with a sealed vapor retarder goes in, then panels, clips or screws, closures, ridge cap, and eave trim. Curbs get crickets on the upslope side.
5
Seal And Hand Over
Laps, curbs, and penetrations are sealed and checked, gutters are tested, and you get a maintenance list for spring and fall walks.

Commercial Roof Repair detailsCommercial Metal Roofing Questions From Florence Owners
The five metal roofing questions from the owner file, answered for Florence buildings.
Which metal panels are used on commercial buildings?
Two main types: standing seam, held by concealed clips under raised seams, and exposed-fastener R-panel or PBR, screwed through the face. Standing seam slides with heat and allows lower slopes with the right seam; R-panel needs more pitch. Offices, schools, and retail lean standing seam, while shops, barns, and warehouses usually carry R-panel.
What gauge, finish, and insulation should a new metal roof have?
Most commercial roofs use 24-gauge steel for standing seam and 26-gauge for many R-panel buildings. Galvalume steel resists rust, and PVDF paint holds color longer than SMP. Under the panels, faced blanket insulation with a sealed vapor retarder keeps warm, humid air off cold steel, which stops condensation dripping on cold mornings.
Can a new metal roof go over an existing flat roof?
Yes, with retrofit framing. Light-gauge steel purlins and sub-framing build slope above the old membrane and bear on columns or bearing walls. Panels then shed water to new gutters, which can retire leaking interior drains. An engineer checks the added load, the space between roofs is vented, and existing units get raised or new curbs.
How are leaks repaired on an existing metal roof?
By replacing the small parts that seal it while the panels stay. Backed-out screws get new screws and washers, one size up in worn holes. Dented panels are swapped for the same rib profile. Laps are scraped, stitch-screwed, and resealed with butyl tape, and curb flashing is refastened with a cricket upslope.
What routine maintenance keeps a metal roof watertight?
A walk each spring and fall and after hail or high wind. Check fastener rows near the eave, ridge, and end laps; clear gutters, valleys, and downspouts; renew cracked sealant at curbs and boots; refasten lifted trim and ridge cap; and touch up scratches. A dated photo log shows which spots keep needing work before winter.
