So copper roofs. Right. You see them on those older town libraries… the ones with erosion patterns that make ‘em look like they weep green-blue tears. And the rich jerks with those overly tidy garden hedges—yeah, their roofs look like melted-down coins. But they’re sturdy. Like, very. Except, whole thing goes sideways when fasteners crack. You’d think copper would outlast the skeleton of the house. But no. It’s like sword and sheath turning on each other after decades of camaraderie. Galvanic messes.
Okay, but why do fasteners even crack, right? Heat cycles pull at the seams like a bad marriage. Then the wind gets in there, laughs a little too hard, and… pop. Or worse: they shift just enough to invite rain in. It’s a tiny betrayal. One small screw becomes the leak that eats your holiday bonus.
Cracks Aren’t the Whole Problem
Not always split-middle obvious. Sometimes it’s more like the screw’s lost the will to grip. Head’s fine. Threads? Mush. Copper stretches a bit over years, and if it was installed when someone was hurrying home for lunch meat, well—trouble now.
And sure, let’s not even start talking about dissimilar metals. Stainless steel in copper? Really? Who thought that clash would hold forever? That’s like marrying salt and battery acid then asking for a gentle honeymoon.
So yeah, cracked fasteners, or “fatigued,” or just plain played out entirely, usually show up around midlife of the roof. Somewhere between patina-polish and the smell of raccoon in the attic.
When it comes to roofing, the importance of a strong and secure roof cannot be overstated. A key component in ensuring the durability and stability of your roof is the type of screws you use. Roofing screws play a vital role in holding your roof together and protecting your home from the harsh external environment.

Alright—Now What? Tools, Sorta
It starts with knowing if you can even get to the thing. Standing seams aren’t exactly begging you to dig in. You ever try to disassemble a can of anchovies without ruining it? Little like that. So forget drills first—start with gentle prying. And by “gentle” I mean you will almost definitely bend something you didn’t want to.
You’ll need: flat bar, two hand types of pliers (needle and channel-locks help), stubby screwdriver that makes your hand cramp, sealant the color of grandma’s cough syrup (it’s copper-compatible, just trust me), and replacement fasteners. Pure copper ones if you can find. Not that nickel-plated junk masquerading as ‘roof-rated.’
Oh—gloves help except when they don’t. Sometimes you need fingertip feel, which means swearing later when you slice your knuckle on an edge no human should’ve fabricated.
Actual Steps, More or Less
Okay, you’re on the roof. Hopefully it’s not windy and you didn’t skip breakfast. Find the cracked or weepy spot—rain’s probably pointed it out already. Use the flat bar to gently (ha) bend up the seam near the fastener. Try not to deform it worse than the issue.
If the screw’s snapped—welcome to a bad afternoon. You’ll need to extract it without stripping the copper around it. Drill it out slowly. Slow like reading tax forms in French.
If it’s just loose or rusted weirdly, back it out. Replace with same size or one-degree thicker. Use copper if you can, but if not—bronze MAYBE. Definitely no zinc-plated garbage unless you like corrosion poetry.
Tighten. Carefully. Not truck-wrench tight. Just enough for it to hold hands without breaking fingers. Then clean nearby spot with acetone, apply tiny bead of sealant, flatten seam back. Stand up. Curse briefly. It’s fine.
Probably one of the most common mistakes that people seem to make is the type of screw used. There are many different types of screws available in materials and shapes of the head or thread type—all intended to undertake various tasks. Wood screws will work well when drives are made into wood, machine screws are for metal-to-metal fastening, and so on.

Using the wrong screw is sure to result in structural failures, such as snapping of screws with pressure or just pulling out over time. More importantly, screw selection becomes much more crucial when working in different environments where the right screw will avoid issues like corrosion.
Don’t Trust Memory Here
Mark where you’ve fixed things. Sharpie under the seam lip. Something you’ll remember in six years when it fails again. Or be nice and write a note for the future roof-wrangler: “Fixed this in June ‘24 — janky screw pulled from hell. You’re welcome. -D”
Oh. And don’t forget to test your fix. Hose spray works. Ideally not someone else holding the hose while you hiss orders from the peak. Just… make it a solo operation when possible. Easier to blame yourself.
Mistakes—A Greatest Hits List
1. Over-tightening the new fastener. Feeling strong, ruining everything.
2. Using the wrong sealant. Caused more leaks than it fixed. Just ask the 2011 south annex of St. Joseph’s rectory. Disaster.
3. Not checking surrounding fasteners. If one’s gone, three more are thinking about it.
4. Forgetting to measure depth of screw hole—then bottoming out. Snap. Goodbye.
Also, big one? Don’t work too close to midday in July. Copper cooks skin faster than bad relationships burn bridges.
Anyway, Final Thoughts—or Whatever
Look. Copper roofs are like the quiet genius kid in 6th grade who didn’t say much but aced math while you were still chewing your pencil. But even geniuses get tired. The fasteners? Grunts of the roof world. Serve quietly, break suddenly, fix only when the ceiling says “hello rain.”
Repairing them’s a weird mix of sculpture and carpentry and regret. If you’re careful and a little lucky, you’ll get it right without opening a bigger wound. But don’t pretend it’s a one-time job. These roofs whisper to you over years. Sometimes with wind. Sometimes with water. Sometimes just with the sound of cracking metal when you least expected it.
Good luck up there. Don’t drop the screwdriver—they’re murder to find in gutters.
