Commercial Metal Roofing
Working as a Winchester metal roofing contractor, we install standing seam and R-panel roofs, repair aging panels, and frame new metal roofs over ponding flat ones.
Your First Visit
Is This Roof A Fit?
A Winchester metal roofing contractor weighs fasteners, slope, and upkeep before choosing a panel, since one difference shapes leak risk.
Metal Roof Trouble
Metal roofs tell you where the next leak will be, often well before it reaches the ceiling.
Orange stains along a panel end lap where water has started to sit.
Ridge or rake trim with missing closures and loosened fasteners.
Leaks lining up with purlins where washers have cracked.
Stains on the insulation below a leaking sidewall flashing.
Heads lifted off the panel by years of heat and cold cycling.
Hail dents or foot traffic damage that opens the lap.
A dried bead around a rooftop unit curb letting water in.
Metal Roof Options
Panels, gauge, finish, and framing are chosen for the building and how long you plan to keep it.
Standing seam is often 24 gauge with concealed clips; R-panel is often 26 gauge with exposed screws. Trim pieces match the panel finish to avoid mixed-metal corrosion.
Fits: New roofs on offices, schools, shops, and warehouses.
Backed-out or rusted screws are replaced with new screws and washers. Leaking end laps are separated, cleaned, taped with butyl, and restitched.
Fits: Aging R-panel roofs with leaks along screw rows and laps.
A light steel sub-frame sits over the existing roof, adding slope and room for insulation between new purlins. An engineer confirms the structure can carry it.
Fits: Ponding flat roofs or worn R-panel kept as a dry ceiling.
Benefits
Metal suits buildings with slope, and a retrofit frame gives slope to buildings that lack it.
The Main One
Standing seam panels hide their fasteners under raised seams and slide on clips as the steel expands and contracts, so the screw holes that leak on older R-panel roofs are gone from the field.
Heavier gauge panels and solid ridge cap fastening resist both.
PVDF holds panel color in strong sun; SMP and bare Galvalume cost less.
Retrofit framing leaves space to add insulation without a tear-off.
Call and tell us whether the panels have exposed screws, how old the roof is, and where water shows up inside.
Metal Roof Steps
Each metal roof starts with the fasteners and laps, then moves to the bigger choices.
We walk the panels checking screw heads, washers, end laps, gutters, valleys, pipe boots, and ridge and eave trim, then look for rust and wet insulation from inside. Rust stains under a lap or along a screw row show where the next leak will appear.
Scattered fastener and lap leaks get repaired. Rust holes across the field, crushed panels, or a flat roof that ponds point to new panels or retrofit framing.
Standing seam or R-panel is picked by slope and upkeep, then gauge and PVDF, SMP, or bare Galvalume finish, with trim matched to avoid mixed metals.
Panels, trim, and new curbs go on, then a twice-yearly walk is set, plus a check after hail or strong wind, with a written log of each repair.

Industrial roofingMetal Roof FAQ
On standing seam vs R-panel commercial roofs, the difference is the fasteners. Standing seam hides them under raised seams on clips that let panels move, while R-panel screws through the face of every sheet. R-panel goes on faster and costs less material; standing seam suits buildings where fewer exposed fasteners matter long term.
Most commercial panels are 24 or 26 gauge steel, with 24 common on standing seam and 26 on exposed-fastener R-panel. On metal roof panel gauge and paint finish in Winchester, PVDF holds color best in strong sun, SMP costs less for shops and farm buildings, and bare Galvalume skips paint.
A light steel sub-frame installed over an existing flat or metal roof so new panels sit above it. Retrofit framing over a flat roof in Kentucky adds slope to a roof that ponds, keeps old R-panel in place as a dry ceiling, and leaves room for insulation between the new purlins. An engineer confirms the structure first.
Fastener, panel, and flashing repairs where water has started to get in. Backed-out or rusted screws are replaced with new screws and washers, crushed or dented panels are swapped, leaking end laps get butyl tape and new stitching, and cracked sealant at unit curbs is cut out and redone.
Twice a year, and again after hail or strong wind. Commercial metal roof inspection and maintenance covers screw heads and washers, gutters and valleys, pipe boots and curbs, ridge and eave trim, and the panel surface. Keep offcuts and branches off the panels, since loose steel scraps rust and stain the finish.
Often, yes. Long metal panel runs shed a lot of water to one eave, so gutters and downspouts need the capacity to carry it. Leaves and grit left in gutters and valleys hold water against the steel, and gutters should match the panel finish to avoid corrosion where metals meet.
