Commercial metal roof repair in Tucson for shops, warehouses, and plants: loose screws, open laps, rust at cut edges, and cracked skylight panels.
Metal roofs repair well when the panels are solid and the leaks come from fasteners and laps.
Heat moves metal every day. These six problems come from that movement, from rust, and from age.
Afternoon expansion and overnight contraction slowly turn screws out of the purlin. The neoprene washer cracks in the sun, and each loose screw becomes a small leak at the panel rib. Rows near the ridge and eave move the most and fail first.
Sealant tape between overlapping panels dries and splits. Water runs along the lap during monsoon rain and drips off the purlin several feet from where it entered. Stitch screws along the lap loosen at the same time.
Factory coatings protect the panel face, while cut edges at eaves, penetrations, and old repairs rust first. Rust bloom spreads along the panel from there, faster where water ponds behind a curb or at a low eave.
Fiberglass skylight panels yellow, crack, and pull away from their fasteners after years of sun. Rain comes straight through, and the panel lets in less light each year.
Box gutters fill with dust and leaves, and foam closures at the eave and ridge crumble. Wind-driven rain and birds get in through the gaps, and overflowing gutters send water back under the eave panels.
Water dripping inside a metal building is sometimes condensation on the underside of the panels. The insulation facing and that day’s weather separate it from a leak.
Metal roof repairs replace worn parts with the same parts, so the panels keep moving the way they were built to.
| Repair | When It Fits | What It Involves |
|---|---|---|
| Fastener replacement | Leaks at screws across a section | Remove worn screws and drive oversized screws with new washers into solid purlin |
| Lap and seam resealing | Leaks along panel overlaps | Clean the lap, reseal with butyl tape or sealant, and refasten the stitch screws |
| Panel replacement | Rust holes, dents, or foot-traffic holes | Remove the damaged panel and install a new one of the same profile and gauge |
| Skylight panel swap | Cracked or yellowed fiberglass panels | Install new panels that match the rib profile, with new closures and fasteners |
Tight fasteners and sealed laps protect what sits under a metal roof, from stock to equipment.
Tell us where the water lands and whether it shows up on dry days too. That separates a leak from condensation before anyone climbs up.
Metal roof repairs follow the panel layout, working from the ridge down so water sheds over each repair.
A roofer walks the purlin lines, checks every fastener row, lap, ridge cap, and skylight, and marks loose screws and rust spots on a roof sketch.
Surface rust at cut edges and around fasteners is wire-brushed and primed so the repair sits on clean, solid steel.
Worn screws are replaced, laps are resealed, and panels with holes come out for new ones of the same profile and gauge.
Each repaired row and panel is checked again, and the photos go into a short report for your building file.
Metal buildings often pair with these two services.
Plant roofs that mix metal panels with flat sections get repairs scheduled around fans, stacks, and shifts.

When water shows up inside but every screw looks tight, leak tracing finds the path before panels come off.
Commercial roof leak repair in TucsonDaily movement does most of it. Panels grow in the afternoon heat and shrink overnight, which works screws loose, cracks washers, and splits the sealant in panel laps. Rust at cut edges and ponding spots, and skylight panels that crack or pull from their curbs, cause most of the rest.
Yes, when the same profile is still available. Panel profile, rib height, and gauge are measured on site, and the new panel laps under the one above it so water sheds the right way. Older or uncommon profiles take more time to source, and a matching temporary seal keeps the hole dry in the meantime.
In most cases they do. A slightly larger screw bites into fresh steel in the purlin, and a new washer seals the hole. Holes that are wallowed out or rusted through get a patch or a new panel instead.
Watch when it drips. Water on dry, cool mornings with no rain usually comes from condensation on the panel underside, while drips during or right after rain point to a leak. Torn insulation facing makes condensation worse and is part of the inspection.
Surface rust can be. It is wire-brushed to solid steel, primed, and sealed, starting at cut edges and fasteners where it spreads first. Rust that has eaten through the panel means that panel gets replaced.
Most hail dents are cosmetic and leave the panel watertight. Dents that crack the finish or pull fasteners loose get repaired, and documented storm damage goes to your insurer with photos and dates. Dented skylight panels and crushed ridge caps get checked on the same walk.
