As a Richmond commercial metal roof repair contractor, we replace failed screws, reseal end laps, and swap rusted panels on steel buildings.
A Richmond commercial metal roof repair contractor presses on the steel and counts the failed screws before recommending anything. These signs sort the roof quickly.
Steel roofs leak at the joints and fasteners long before the panels wear out. The featured condition causes most calls.
Water runs straight into the joint where one panel overlaps the next one downslope. On low-slope R-panel roofs it also gets drawn into the lap by capillary action, and rust stains along the lap edge show where it has been sitting.
Usually MeansLap opened, brushed, primed, and resealed with new stitch screws.
Sun dries the rubber under each screw head until it splits and lets water down the shank.
Foam closures fall out or rot, and wind-driven rain blows under the ridge cap.
Blocked downspouts send water back toward the wall and over the eave trim.
Ice dams push meltwater back up under end laps and closures in late winter.
These four repairs cover nearly every leak on an exposed-fastener or standing seam roof.
Firm screws with good washers are snugged down. Screws with cracked washers are replaced, stripped holes get a larger-diameter screw, and roofs with heavy back-out get fastener caps or sealant over the heads.
Rusted lap edges are wire-brushed and primed before new sealant or butyl tape goes in. Missing stitch screws are replaced so the panels clamp together and the lap closes again.
Surface rust on firm steel is brushed, primed, and sealed. Pinholes in a small area take primer plus a reinforced patch or a sheet-metal patch. Panels rusted through get replaced with a matching rib profile.
Gutter end caps and joints are resealed and hangers reset for slope. Rusted valley metal is replaced, and ridge caps are refastened with new closures and sealed laps between cap sections.
Repairing the fasteners and laps keeps a steel roof in service and keeps water off what is stored under it.
That pattern points to washers or laps, which is a repair job. Send us the building address and a note on where the drips show up.
Metal repairs follow the water: fasteners first, then laps, trim, and any steel that has rusted through.
From inside, we look for wet batts and rust at the deck side. On top, the walk covers screw rows, end laps, ridge closures, gutters, and every curb or skylight panel.
Screws that still bite are snugged. Screws with split washers come out, new screws and washers go in, and stripped holes take an upsized fastener.
Laps are cleaned, brushed to bare metal at rust, primed, and sealed with butyl tape or reinforced sealant. Closures and ridge caps are refastened.
Panels that fail the screwdriver test are replaced in a matching profile, along with rusted eave trim and valley metal. Photos go to you when the work is done.
Mixed buildings and busy plants usually need more than one kind of repair.
Where a metal high roof drains onto a membrane section, the joint and low roof need flat roof repair as well.
Water running along purlins can land far from the lap, so roof leak repair traces it before any panel work.
Metal roofs with exhaust fans and dust collectors need industrial roof repair at the curbs and vents.
Answers on screws, laps, rust, and trim.
Two things break the seal: the rubber washer dries and cracks, or panel movement backs the screw out of its hole. Panels heat and grow every day, then cool and shrink, and that motion works against each fastener. A full pass covers every screw, because one leaking row means others are close behind.
End laps leak more than side laps because water runs straight into the joint. The lap is opened or cleaned, rusted edges are brushed and primed, failed sealant and fasteners are replaced, and the joint is sealed with tape or reinforced sealant. Missing stitch screws go back in so the panels clamp tight.
Small rust spots on firm steel can be. Surface rust is brushed, primed, and sealed, and pinholes take a reinforced or sheet-metal patch. Panels rusted through across a larger area need replacing, and rust along the eave usually means new bottom panels or trim. Replacement panels match the rib profile so laps seal.
Gutters get resealed end caps and joints, new sections where rusted, and hangers reset so water runs to the downspout. Valleys are cleared and rusted metal replaced. Ridge caps get new closures, fresh fasteners, and sealed laps. Downspouts are checked too, since a blocked one sends water back toward the wall.
Membrane repairs center on seams, patches, and flashing adhered to the sheet, using a hot-air welder, primer, and roller. Metal repairs center on fasteners, laps, trim, and new steel, using a screw gun, brushes, sealant, and snips. Wet insulation on metal is found from inside, where wet batts and rust show.
Tell us the panel type and where the drips land, and we will set up a fastener and lap check on your steel roof.
