As a Lansdowne commercial roof repair contractor, we repair torn and rusted metal panel edges, laps, and fasteners on shops, garages, and warehouses.
Lansdowne commercial roof repair on metal buildings often comes down to the panel edge: is there enough solid steel left to fasten into?
When there is, the edge gets repaired with a detail that restores secure fastening. We check the adjoining laps and the support underneath before choosing that detail.
When rust or tearing has taken too much metal, the panel gets replaced. Sealant spread along a weak edge looks like a repair for a season and then lets go.
Panel edges show damage before the rest of the roof does. These are the signs to look for.
Panel edges that flutter or lift in wind have lost fastener grip, and each lift loosens them more.
Low panel ends hold water and debris until the steel rusts through, leaving holes right at the drip line.
Steel torn around fasteners at the edge gives screws nothing to hold, so they back out with every gust.
Thick sealant beads along an edge often hide rust that kept spreading underneath.
Side laps near a damaged edge open as the panel moves more freely than it should.
Edge repairs bring back secure fastening, which keeps the whole panel from working loose.
Edges lose grip and lift a little more in each storm.
An edge detail with new fasteners into solid steel holds the panel down again.
Steel at the eave thins until holes open.
Panels too thin to fasten are replaced with matching profiles.
Screws tear through weakened metal at the edge.
Repair plates or new panels restore something solid to fasten into.
Old sealant traps moisture against the metal.
Old sealant comes off so the real condition of the edge is visible before repair.
Edge work ranges from refastening to full panel replacement.
New fasteners go into solid steel and firm supports, with fresh washers to seal each one.
Where a small area is torn, a matching plate restores a solid surface to fasten and seal.
Panels with too little sound metal are swapped for the same profile and fastened along the full edge.
Separated laps next to the edge are cleaned, sealed, and refastened.
A walk of every eave and rake edge finds weak spots before wind finds them.
Call and tell us where on the building it is. Loose edges get worse with every storm, so they go to the front of the list.
Call UsEdge repairs start with how much solid metal is left.
Eaves, rakes, and panel ends get checked for lifting, rust holes, and torn fastener holes.
Steel at each damaged edge is probed for thickness, and supports below are checked for firm fastening.
Each damaged panel is marked for a repair detail or replacement on a sketch with photos.
Edges get new fasteners, plates, or replacement panels, and nearby laps are resealed.

Answers for Lansdowne owners of metal shop, garage, and warehouse roofs.
They are when enough solid metal remains for a secure connection. We inspect the adjoining laps and the support underneath before choosing a detail. Where rust or tearing leaves nothing to fasten into, replacing the panel beats a sealant bead along the edge.
Edge work happens almost entirely from the roof. Only the space directly under a panel being swapped needs clearing, and that panel is closed up before the crew leaves.
A roofer who checks how much solid metal remains, explains repair versus replacement panel by panel, and documents it with photos. Edge repairs depend on that judgment.
By walking every eave and rake, probing steel thickness at damaged spots, testing fastener grip, and checking the supports below.
After strong wind, a walk of the eaves and rakes catches edges that lifted or lost fasteners before the next storm pulls them further.
Most common rib profiles are still made, so a replacement panel usually lines up with the ribs and laps beside it. Color and finish can differ from weathered panels, which we point out in the scope before ordering.
Sealant on a moving edge cracks within a season, and it traps water against the steel underneath. A fastened repair holds the panel still, which is what keeps the edge closed through the next storm.
Yes. Gutters pulling away from the eave or trim with missing fasteners let water back up under panel ends, so loose trim and gutter straps get refastened along with the panel edge.
Send the address and where the damaged edge is. We will check the metal and price the repair.
