Metal Roof Repairs Done Right
Leaking screws? Rust spots? Storm damage? We fix Colorbond, Zincalume, and all metal roofs—often the same day. Proper repairs with quality materials.
Metal roofs are durable but not maintenance-free. Frankston's coastal conditions accelerate wear on screws, flashings, and coatings. We use Class 4 fasteners and marine-grade sealants that actually last in salt air.

Why Metal Roofs Fail in Coastal Areas
🔴 The Hidden Problem: Screws
Your metal roof has 400-800+ screws. Each one has a rubber washer that seals against water. After 10-15 years:
- •Rubber washers crack, shrink, and harden
- •Standard screws rust (corroded heads, stained roof)
- •Water enters around every failed washer
This is why metal roofs often leak with no visible damage.
⚠️ Coastal Accelerated Wear
Frankston's proximity to Port Phillip Bay means salt spray reaches even "inland" suburbs. Salt exposure causes:
- •Class 3 screws fail 50% faster than rated
- •Flashings corrode at joints and edges
- •Cut sheet edges rust if not sealed
That's why we only use Class 4 (stainless) fasteners for Peninsula repairs.
Metal Roof Problems We Fix
Screw & Washer Replacement
Replace deteriorated rubber washers and corroded screws with Class 4 stainless-capped fasteners.
Rust Treatment
Treat surface rust with converter, prime, and coat to stop spread. Remove and replace if rusted through.
Sheet Replacement
Replace damaged, dented, or corroded roof sheets with matching Colorbond. Proper overlap and sealing.
Flashing Repairs
Reseal or replace flashings around penetrations, walls, skylights, and roof edges.
Leak Detection & Repair
Track down elusive leaks—often screw washers or hidden flashing failures. Fix the source, not symptoms.
Ridge Cap Repairs
Reseal or replace ridge caps and hip covers. Fix lifting sections and failed sealant.
Why Proper Materials Matter
Screw Quality: Class 3 vs Class 4
| Factor | Class 3 (Standard) | Class 4 (Stainless Cap) |
|---|---|---|
| Coastal Lifespan | 5-10 years | 20-25+ years |
| Rust Staining | Yes—streaks down roof | No—stainless cap |
| Cost | Cheaper upfront | ~30% more |
| 10-Year Total Cost | Higher (needs re-doing) | Lower (lasts) |
We exclusively use Class 4 fasteners for all Frankston and Peninsula repairs—they cost slightly more but last 2-3 times longer in our coastal environment.

Metal Roof Repair FAQs
Why is my metal roof leaking even though it looks fine?
The #1 cause of metal roof leaks is worn screw washers—not visible damage. Every screw has a rubber washer that seals against water. After 10-15 years, these washers deteriorate, crack, and shrink, letting water in around every screw head. From the ground your roof looks perfect, but those 500+ screws are each a potential leak point. We can reseal or replace all screws as part of our repair service.
Can you repair rust on a Colorbond roof?
Yes, if caught early. Surface rust (affecting the paint layer only) can be treated with rust converter, primed, and repainted with compatible metal coating. If rust has penetrated through the steel creating holes or thinning, that section needs replacing. Colorbond rarely rusts unless the coating is damaged by scratches, foot traffic, or corrosive deposits. We'll assess and give you honest advice on repair vs. replace.
What causes Colorbond roof sheets to corrode?
Colorbond is extremely durable but can corrode from: 1) Cut edges where raw steel is exposed, 2) Scratches from foot traffic, branches, or debris, 3) Metal filings or swarf from nearby construction that rust onto the surface, 4) Galvanic corrosion from incompatible metals touching, 5) Severe coastal salt exposure over time, 6) Debris buildup trapping moisture. Most issues are localised and repairable.
How do you fix leaking flashings on a metal roof?
Flashings seal around penetrations (vents, skylights, pipes) and at wall/roof junctions. We repair by: cleaning the area thoroughly, removing old sealant, checking for rust underneath, applying rust treatment if needed, and resealing with premium polyurethane or silicone sealant rated for metal roofs. If flashings are badly rusted or incorrectly installed, we fabricate and install new ones.
Do you use proper Class 4 screws for repairs?
Absolutely. For coastal areas like Frankston, we only use Class 4 (stainless steel cap) fasteners with EPDM rubber washers. Standard Class 3 screws corrode within 5-10 years in salt air. We also carry the correct thread types for different metal profiles—using the wrong screw causes leaks and strip-outs. All our replacement screws are colour-matched to your roof.
Can you replace just one damaged metal roof sheet?
Yes, individual sheet replacement is common. We source matching Colorbond sheets (same profile and colour), carefully remove the damaged sheet, check battens underneath, and install the new sheet with proper overlaps and sealing. Colour matching can be tricky on older roofs as Colorbond fades slightly—we'll advise if there'll be a visible difference.
What warranty do you offer on metal roof repairs?
All metal roof repairs carry our 10-year workmanship warranty. This covers screw replacements, flashing repairs, sheet replacements, and any other work we do. If it leaks due to our repair, we come back and fix it at no charge. We also warranty that we've used appropriate materials (Class 4 screws, compatible sealants, genuine Colorbond for replacements).
How quickly can you respond to metal roof emergencies?
For genuine emergencies (active leak during rain, storm damage, large hole in roof), we offer same-day response—call before 10am and we'll be there. We carry common repair materials on our vehicles for immediate fixes. After hours and weekends, call our emergency line and we'll arrange a temporary weatherproof solution until permanent repairs can be done.
