Most Common Cause of Metal Roof Leaks
Screws back out as panels expand and shrink, washers crack, and holes widen with each freeze-thaw cycle. A new oversized screw and washer seated into the purlin closes the leak.

Roof Problems
Commercial Metal Roof Repair Problems in Anderson
Metal roofs leak at the joints more than the panels. These six points cause most of the drips we trace.
Metal Roof Flashing Repair
Ridge caps, rake trim, and wall flashing loosen and rust first. Failed sealant comes off, and bent or rusted pieces get replaced with new metal formed to fit.
Metal Roof Repair After Hail
Hail splits panels, cracks skylights and vent caps, and loosens screws near impacts. Each hit gets photographed, and the ones letting water in get repaired.
Rust at Laps and Ends
Water held in side laps and at the low end of each panel rusts the steel from the edge in. Cleaned, primed, and sealed laps stop the spread.
Cracked Skylight Panels
Older fiberglass skylight panels turn brittle and crack along the fasteners. Same-profile replacements drop into the run of metal.
Condensation Mistaken for Leaks
Drips on cold mornings can come from moisture forming under the panels. Checking the insulation and the weather before the drip separates the two.
Why Repair Early
Why Commercial Metal Roof Repair Pays Attention to Anderson Weather
Metal moves with every temperature swing, so repairs focus on the parts that move.
Screws That Stay Tight
Fresh washers and oversized screws grip enlarged holes and seal under the head. Seating each one into the purlin, instead of the panel alone, keeps it from backing out again through the next winter of freeze and thaw.
Panels That Stay Solid
Stopping rust at laps and ends keeps it from eating through the steel.
Trim That Sheds Water
New flashing at walls and curbs sends water back onto the panels.
Dry Floors Below
Shops and pole buildings stop dripping onto equipment and stored stock.
Repair Methods
Commercial Metal Roof Repair Methods in Anderson
Metal repairs stay mechanical first: new fasteners, sealed laps, and replaced steel.
Oversized Fastener Swaps
Stripped holes get a screw one size up with a new EPDM washer, driven snug into the purlin so the washer seals without being crushed flat.
Panel Replacement
Rusted-through or split panels come out and new panels of the same rib profile and gauge go in, lapped and fastened to match the run around them.
Formed Flashing and Trim
Bent or rusted ridge caps, rake trim, and wall flashing are replaced with new metal bent to fit, then fastened and sealed into the panel ribs.
Rust Showing Around the Screws?
Call and describe the panels. Rust at fasteners and laps is easier to stop before it eats through the steel.

Fasteners
How to Fix Leaking Screw Holes in a Metal Roof
Pull the old screw, install a new one a size larger with a fresh washer, and seal the head. It has to land in the purlin; a hole that missed the framing gets filled and sealed.
Should every screw on the roof be replaced?
Only where screws are loose, leaking, or rusted. A row-by-row check finds them, and sound fasteners stay in place.
Hail
Do hail dents on metal panels need repair?
Shallow dents are usually cosmetic. Split panels, cracked skylights, and screws loosened by impact are the repairs that keep water out.
Can photos from a roof walk help with a claim?
Owners often use dated photos of each hit when they talk to an insurer. We take them on the roof walk after a storm.
Cost
What drives the price of a metal roof repair?
The count of screws, laps, and panels needing work, whether flashing must be replaced, how far rust has spread, and how hard the roof is to reach.
Is a coating part of a metal roof repair?
A coating is a separate job. Repairs here focus on fasteners, laps, panels, and flashing so the roof sheds water on its own.
Flashing
What does metal roof flashing repair involve?
Old sealant and loose pieces come off, then the flashing is refastened or replaced and sealed to the panels and walls. Rusted or bent pieces get new metal formed to fit.
Where does metal roof flashing fail first?
At ridges, rake edges, wall transitions, and around curbs and pipes, where panels meet other parts of the building and move against them.
