Patch on Patch
Years of tar and mastic patches stack up at laps. We test whether they hold or cut them out so the coating bonds to clean metal.

Coating That Restores Older Metal Roofs After Screw and Lap Repairs
As a Lyons metal roof coating contractor, we bring older metal roofs back into service with a round of screw and lap repairs, then a full coating.
Metal Roof Coating for Older Lyons Buildings
Lyons metal roof coating jobs often involve roofs that have been patched for years. Coating works only over panels that are still firm, so the walk looks for rust-through, missing screws, and wet insulation first.
Older roofs usually need a full round of fastener replacement and lap reinforcement before coating. Main-street storefronts and ag buildings in town often carry several generations of patches, each tested before it stays.
- Full screw replacement on stripped runs.
- Lap reinforcement with fabric and sealer.
- Old patches tested or removed before coating.
- Moisture readings under the oldest leaks before anything is priced.
Lyons Older-Roof Problems We Fix Before Metal Roof Coating
Older roofs carry a history. These four conditions decide the repair list.
Stripped Screw Holes
Screw holes widen over time. Oversized fasteners grip fresh metal and stop the leak at each hole.
Rust-Through at Eaves
Eaves and gutters rust first on old roofs. Holed sections get patched with matching metal or replaced.
Wet Insulation
Leaks left for years soak insulation. Moisture readings find it, and wet areas come out before coating.
Brittle Lap Sealant
Old butyl and caulk at the laps dries and cracks with age. It gets cut out where loose, and fabric and fresh sealer go in its place.
Long-Running Ceiling Leaks
Stains that came back for years mark the worst laps on the roof. We trace them from inside and add those spots to the top of the repair list.
Benefits of Coating Your Roof
For an older roof, coating after repairs keeps the building in use and adds service life. Compare it with full replacement.
| Roof Factor | Coat The Roof | Replace The Roof |
|---|---|---|
| Older panels | Kept, repaired, and sealed | Removed and replaced |
| Worn screw holes | Oversized screws and sealed heads | New holes in new panels |
| Planning cost | About $2.50 to $4.00 per sq ft | About $5 to $8 per sq ft |
| Business below | Stays open | Disrupted during tear-off |
| Next upkeep | Recoat the topcoat | Screw and seam checks |
Commercial Roof Coating Options for Lyons
Older roofs in Lyons fit these systems. The roof walk, the moisture readings, and the patch tests decide which one your building gets.
Commercial Metal Roof Coating
Older R-panel roofs with stripped screws take the full metal build after a complete round of fastener replacement, lap reinforcement, and rust priming.

Silicone Roof Coating
Low sections with years of ponding take silicone once drains are cleared, wet insulation is cut out, and any sagging deck under the pond is repaired.
Silicone roof coating
Acrylic Roof Coating
Steeper older panels with faded, chalky paint take acrylic over primer, after the chalk is washed off and failed patches at the laps are removed.

Spray Foam Roofing
Leaky, drafty shops on aging lots can take spray foam over dry panels with a UV topcoat, closing hundreds of small leak points under one layer.

Shingle Roof Coating
Shingled fronts that still lie flat on older buildings can be coated in the same visit, once lifted tabs are sealed and the deck passes a probe test.

Call and tell us the roof's age and how many leaks you see. We bring screws to the walk and test a few spots.
How Lyons Metal Roof Coating Brings an Older Roof Back
Older roofs get more repair time up front. This is the order.
Inspect Your Roof
We walk the roof, check every patch and lap, count stripped and missing screws, and take moisture readings wherever leaks have run for years.
Remove Failed Patches
Loose tar and mastic patches come off down to clean metal, and the ones that still hold are tested for adhesion before we decide to keep them.
Full Screw Round
Stripped screws are replaced with oversized fasteners, missing ones are filled, and every head gets sealed, which on old roofs stops many leaks on its own.
Reinforce And Prime
Laps get fabric set in fresh sealer, brittle old caulk is cut out, and rusted areas at eaves and gutters get ground and primed with a rust-inhibiting primer.
Coat And Check
Base and top coats go on to the specified thickness, followed by a final walk with wet-mil checks and photos of every repaired area.

Waterloo metal roof coatingMetal Roof Coating Questions From Lyons Owners
Questions from owners of older buildings in Lyons about old patches, worn screw holes, matching panels, foam, and what the repair list includes.
01
What should Lyons businesses know before coating an older metal roof?
Coating works only over panels that are still firm. We check for rust-through, loose or missing screws, and wet insulation, then fix them, and the coating seals the roof as one surface.
02
Is Any Metal Roof Too Old to Coat?
Age alone is fine. Panel strength, rust-through, and wet insulation decide it, and the roof walk answers that.
03
What Raises Lyons Metal Roof Coating Cost on Older Roofs?
Patch removal, a full screw round, lap fabric, and wet insulation removal. Coating plans at about $2.50 to $4.00 per square foot.
04
Metal Roof Coating for Lyons Businesses: Can You Coat Over Old Patches?
Firm, well-adhered patches stay and get primed. Loose or cracked ones come off first.
05
How many screws get replaced on an older roof?
Every stripped, missing, or backed-out screw. The repair list gives the count from the walk.
06
Should an older roof get foam instead of coating?
Foam makes sense when the building also needs insulation or the roof has hundreds of small leaks. Otherwise, the coating build after repairs costs less and keeps the panel profile.
07
Can you match a replacement panel to the old profile?
Most older R-panel and PBR profiles are still made, and we measure rib spacing on the walk. A replacement panel is primed and coated with the rest of the roof so it blends in.
08
What paperwork comes with the repair list?
Photos, counts of screws and laps, square footage, and the coating system, laid out so you can compare prices line by line with any other roof proposal.
