When you've ever worked with a leaking chimney or a roof valley that simply won't stay dry, you've probably noticed that using rolled copper flashing is the very best way to repair the problem for good. It's one of those materials that professionals swear by, and for good reason. While you could theoretically choose cheaper choices like aluminum or plastic, there is something about copper that just seems right—both in terms of just how it looks and how it really performs when the particular weather gets awful.
I've observed many people try to cut corners with their roofing materials, only to repent it five many years later when they're back on a ladder having a tube of caulk. Copper is different. It's a "set it and forget it" kind of materials. Once you get this installed properly, it's likely likely to outlast the shingles, the particular siding, and perhaps even the person who put it there.
Why the "Roll" Matters More Compared to You Think
When you're buying flashing, you'll usually see it within pre-cut strips or even in big progresses. Choosing rolled copper flashing provides you a level associated with flexibility that pre-cut pieces just can't match. The biggest benefit here is the insufficient seams.
Every period you have to overlap two parts of flashing, you're creating a possible entry point with regard to water. It doesn't matter how much sealant you utilize; over time, houses change, temperatures change, and those joints can fail. When you make use of a long, continuous roll, you can cover an whole valley or even a long stretch of the dormer without an individual break. It's a far cleaner look and also a much safer bet against leaks.
Plus, copper is incredibly malleable. If you're operating around a weirdly shaped chimney or even a custom windowpane frame, you are able to flex, fold, and tuck the copper specifically where it requires to visit. It's gentle enough to work with manual tools but tough enough to hold its shape once it's in place.
The particular Beautiful Reality of the Patina
Let's talk about the elephant in the space: the color. When you initially install rolled copper flashing , it's likely to be that vivid, shiny, penny-orange colour that catches everyone's eye. Some individuals love that "new money" look, but it doesn't stay that way regarding long.
Because copper is a reactive metal, this starts to oxidize the minute it's subjected to the air and rain. On the 1st few months, it'll turn a serious, chocolatey brown. Eventually—and we're talking years here—it develops that will iconic sea-foam green patina.
The cool factor about this isn't just the aesthetic, although. That patina is actually a safety layer. Unlike iron, which rusts and eventually falls apart, copper's "rust" actually seals the metal and protects it through further corrosion. It's basically nature's way of painting the roofing for you personally. If you're creating a high-end home or working upon a historic recovery, you really can't beat that look. It screams high quality.
Getting the Installation Right
If you're arranging on DIY-ing this particular, or even when you're just keeping an eye on a contractor, there are some quirks about rolled copper flashing you need to be able to know.
First off, a person absolutely have in order to use copper nails. I can't pressure this enough. In case you use metal or aluminum fingernails to hammer straight down copper flashing, you're going to run in to something called galvanic corrosion. Basically, when two different metals touch and get damp, they have a little chemical reaction that causes the less strong metal to vanish. If you use steel nails, they'll rot out within no time, as well as your expensive copper may just blow away in the following windstorm. Stay with copper-on-copper.
Secondly, brain the thickness. Copper flashing is generally scored in ounces per square foot. For most residential roofing jobs, 16-ounce copper is the sweet spot. It's thick enough in order to be durable and hold its shape but not therefore thick that you'll need an industrial metal brake only to put a 90-degree bend in it. You are able to usually reduce 16-ounce copper with a good pair of tin snips, though your forearms might feel it the next day if you're doing a lot of trimming.
Is It Worth the additional Cash?
I won't lie to you—copper is expensive. In the event that you compare the price of a 20-foot move of copper to a 20-foot roll associated with aluminum at the particular hardware store, you might have a bit of heart palpitations. It's a premium item, certainly about it.
But you possess to look in the "cost for each year. " A good aluminum flashing may last 15 or even 20 years just before it starts to get brittle or even the coating peels off. Rolled copper flashing can certainly last 70 in order to 100 years. In case you plan on living in your own house for a long time, or even if you would like to increase the resale value, copper will pay for itself. It's one of all those things that home inspectors love in order to see. It informs them that the homeowner didn't inexpensive out on the particular bones of the house.
Also, consider the labour. Most of the cost of a roofing repair isn't the material; it's the guy ascending up there to complete the work. Precisely why pay someone to install a $20 piece of flashing that's going to fail in the 10 years when you could pay them the same labor cost to install a $100 part of copper that will certainly last a hundred years? It is just smart.
Common Mistakes in order to Watch Out Regarding
Even with the best materials, items can go sideways if you're not careful. One typical mistake I notice is people failing to remember about "staining. " As the copper patinas, the rainfall runoff can have a bit of that color by it. If you have light-colored stone or white siding directly under your own copper flashing, you might end up with some green streaks over time. It's not a deal-breaker for most, but it's something to consider when you're planning the layout.
Another factor is the "softness" of the metallic. Because rolled copper flashing is definitely so easy to flex, it's also simple to dent. In case you're walking on the top, try to avoid stepping on typically the flashing. It won't necessarily ruin the ability to keep out water, however it can look a little sloppy if the metal is most crinkled up from boot prints.
Lastly, ensure you're buying "dead soft" or "cold rolled" copper depending on exactly what you need. Most rolls you find for flashing are annealed to become smoother, which is what you want for hand-bending close to chimneys and valleys.
The Consensus on Rolled Copper
At the particular end of the particular day, using rolled copper flashing is about reassurance. There's a particular satisfaction in knowing that the most vulnerable parts of your roof—the valleys, the chimney base, the window headers—are shielded by a material which has been used in construction since the Roman Empire.
It's tough, it's beautiful, and it also deals with the elements better than almost anything otherwise out there. If you're fed up with chasing leakages or perhaps you just would like your home to possess that classic, sophisticated finish, it's really the only way to go. Yes, it'll cost a person a bit more upfront, yet when the rain is pouring down in the middle of the night, you'll be glad a person went with all the good stuff.
Don't overthink this. If the budget allows, get the particular copper. The future personal (and your attic) will thank a person.
