There’s a drip in the workshop again, right under a row of screws. Or the porch roof on your house has rust stains running down from every fastener, and you can’t tell if it needs a few new screws or a whole new roof. Corrugated metal roofing in Daytona Beach takes a beating from sun, salt air and summer storms, and the screws usually show it first.
The good news is that a lot of corrugated roofs can be fixed rather than replaced. You just need someone who’ll check every fastener, edge and lap and give you an honest answer.

What makes a corrugated roof different
Corrugated and ribbed panels are exposed-fastener roofs. The screws go straight through the face of the metal into the wood or steel framing below, and each screw has a rubber washer under its head that keeps rain from following it in. From the yard you can see the rows of screw heads.
Corrugated sheet has the rounded, wavy profile people picture on an old Florida farmhouse or a barn. Ribbed panels have taller, squared-off ribs with flat areas in between. Ribs make a stiffer panel that can span farther between supports and carry more water down a long slope.
Standing seam roofs work differently. Their fasteners are hidden under raised seams, so there’s nothing exposed to the weather. If you’re weighing the two, our standing seam metal roof page lays out the trade-offs.
Why corrugated metal roofing in Daytona Beach leaks at the screws
Most corrugated roof leaks start at a fastener. A few causes come up again and again:
- Sun-baked washers. Florida sun hardens the rubber washers until they crack and stop sealing, often long before the painted metal around them wears out.
- Heat movement. Metal grows in the afternoon sun and shrinks at night. Over years, that back-and-forth works screw holes into ovals, and the washer can’t cover the gap.
- Bad installs. A screw driven too tight crushes its washer. One driven crooked or too loose never sealed in the first place.
- Salt air. Near the coast, the wrong fastener or an unpainted cut edge can rust fast and leave a stain trail down the panel.
Laps are the other common spot. Where one panel overlaps the next, wind-driven rain can push in sideways if the overlap is short or the sealant has dried out.
Repair or replace a corrugated roof?
If the panels are still solid, a re-screw is often the right fix. Each old fastener comes out and a slightly larger screw with a fresh washer goes in, so the threads bite into new material. That stops leaks at the screw heads and pulls loose panels back down tight. It won’t fix rusted-through panels, split laps or bent trim, so those get repaired or replaced on their own.
Replacement makes sense when rust has gone through the metal across a whole slope, when panels have torn loose in a storm, or when the framing underneath has rotted. One badly damaged panel can usually be swapped out, though new metal won’t match the color of weathered panels around it. Our metal roof repair page covers repairs in more detail.
Getting the details right on a new corrugated roof
A corrugated roof is simple, which is exactly why the details decide how long it lasts. These are worth asking any installer about:
- Fasteners rated for the coast. Screws with a coating suited to salt air, set at the right depth and placed where the manufacturer’s diagram says.
- Enough slope. Exposed-fastener panels need a minimum pitch to shed water. On a nearly flat porch or carport, overlaps start to let water in, and a low-slope membrane is often the better choice.
- Closures and trim. Foam closures fill the gaps under each rib at the ridge and eave so rain, bugs and birds stay out. Trim at the edges should be hemmed and fastened tight so wind can’t catch it.
- Separation from other metals. Copper runoff or contact with pressure-treated wood can corrode some panels, so a barrier goes between them.
On a home, panels go over a solid deck with high-temperature underlayment. On a barn or shed, they often span open framing, and the panel thickness has to match that spacing.
Storm damage and insurance
After a hurricane or a strong summer storm, look for panels lifted at the edges, missing screws or bent trim. If the storm caused damage, you file your own insurance claim and pay your own deductible. We photograph and document what we find, write the estimate and work with your adjuster.
How it works

- Get a clear, honest assessment and estimate. We check the screws, laps, trim and any rust, and look inside for signs of old leaks. You’ll get photos and a written estimate, and a re-screw if that’s all the roof needs.
- The work gets done and the site gets cleaned up. The crew finishes the job and cleans up before leaving.
Corrugated metal roof questions
How often does a corrugated metal roof need new screws?
There’s no fixed schedule. It depends on the washers, the sun exposure and how well the roof was installed. If you’re seeing rust rings or drips at the screws, it’s time for an inspection.
Can you put corrugated metal on a house, or just sheds?
Both. Corrugated and ribbed panels go on homes, porches and carports as well as barns and workshops. On a home, they’re installed over a solid deck and underlayment.
Is corrugated metal good near the ocean?
It can be, with the right coating, coastal-rated fasteners and careful sealing of cut edges. Aluminum panels are another option for homes very close to the water.
Does corrugated metal cost less than standing seam?
It usually costs less to install because it uses simpler panels and goes on faster. It needs more upkeep over time because the screws are exposed. We’ll compare both for your roof.
