I once had itchy shingles that I wanted to get scratched …
I don’t see the point of a temporary roof on a house.
What is your preference?
A permanent one.
Permanence. Metal roofs look nice and don’t biodegrade and fall apart in 10-20 years like shingles (unless you count slate shingles, but they’re expensive.) Shingles are basically tar paper, a very weak material that doesn’t weather well.
Ok, I just found out metal roofs actually don’t last forever, that’s marketing wank. I assumed they’d be built to last, but only the copper ones last hundreds of years, and that shit is hella expensive and hard to get for roofing. Metal roofs are designed to wear out also.
I had assumed that high-grade stainless would be a common roofing material, because that would likely last the lifetime of the house–but it’s not even an option as far as I can tell. The closest thing to it is galvanized steel, which rusts (albeit much slower than unprotected steel.) That’s also the same material those corrugated metal roofs on old barns and sheds.
I have a metal roof and it’s nice and all but it does have its upkeep costs as well. Plus it isnt “permanent” either. It’ll last twice as long or more but unless youre planning on an early death, or to dump the house down the road, you’ll get it replaced at some point in your life. And it cost 3 times what asphalt shingles would’ve cost. And thats with the exposed fasteners and before the protective coating. Meaning you can go with asphalt shingles, which even the cheapest 3tab come with 25 year warranty, and still pay less during your lifetime. Hell If youre going to fork over the price for metal roofs, you may as well do the Tesla solar panels, now.
What exactly happens to a metal roof that causes it to need replacement? Most of them have a 20 to 50 year warranty.
Metal does deteriorate. Faster if not cared for properly. Contrary to what seems to be popular belief here, it isn’t permanent. It comes with a 50 year warranty, not lifetime, for a reason. That’s only double the 25 year warranty 3-tab asphalt shingles come with. Yeah it’s twice as durable, but for more than 3 times the price. And thats just the roof. The gallons of sealant/protection needed, arent included in the price of the roof itself. Plus we paid extra for the hidden fasteners, as opposed to exposed, to minimize the chance of a leak. Depending on where you live and what type of protection you have on it, the elements can/will do a number on it. Replacing a damaged panel alone will cost me 5x what replacing ashpalt shingles would. Cost is the main reason people buy asphalt or “temporary roofs”. Asphalt shingles wouldve cost me 1/4 of the price i paid. But the wife overruled me.
Thank you for the info. It disgusts me. If I had the money, I’d start a roofing business using stainless steel plating (well, first I would have to calculate the materials cost to see if I could make money pricing it competitively.) I’d use a grade of stainless that won’t rust ever (well, not for hundreds of years at least) thick enough to withstand hard hits with baseballs and grapefruit sized hail without denting, anodized so the coloring would be permanent, with hidden fasteners included, and guaranteed for 100 years without any maintenance whatsoever.
I wouldn’t even care if I got rich as long as the business stayed afloat. It’s just that I have a strong dislike for things that are so inherently flimsy that they’re expected to wear out and fail when there should be a fairly simple and much more permanent solution. I’d take pride in knowing I had made that option available.
