I could quite possibly be wrong about your abilities. I was just basing my assessment on the advice you gave. That was all I had to go by.

The OP was barely informed (probably by some infomercial) and came here to broaden his knowledge base.

Without knowing his roof, it's hard to say whether it would be simple or not. A poorly installed metal roof can be more of a liability than an asset.

metal vs shingles


Do not confuse the warranty period with the actual length a roof will last. I have done over 200 forensic insurance investigations on houses that have been damaged (wind, water, hail, impact, foundation failure etc.) and I have never met anyone who collected on a roof warranty. The reasons they fail to collect are multiple, sometimes the roofer is out of business, usually they did not read the warranty carefully, and did not realize that they were prorated material only, etc.

So in my experience, length of warranty is loosely, or maybe not at all, correlated with product lifespan. For example, those of you married out there, you probably think you have a lifetime warranty, but most marriages will end in divorce. Go try to collect on that warranty.

As to roof materials, I can certainly speak to roof performance in hurricane country, having done about 180 damage inspections after Katrina and Rita. Low cost three tab asphalt shingles are about the worst, they rarely survive even a minor hurricane, and if they do they need to be replaced. Heavy weight architectural shingles do pretty well, especially if they are properly attached (four or five nails per shingle, high grip nails). I have photos of houses along the coast where one house has three tab shingles, essentially destroyed, and the house next to it has architectural shingles, relatively little damage.

High quality metal roof, properly installed, do very well. When I inspected Jim Bob's pool hall after Katrina, the metal siding was destroyed, but the metal roof was perfect. Very interesting case, pretty typical of quality roof installation. Poorly installed metal roof are catastrophic in hurricanes, the roof comes off in sheets, becoming a lethal hazard.

Clay tile roofs did surprising well, the biggest issue was tile damage from flying debris. They are not common, and they require special installation techniques, but they seem to last a long time, and perform well under stress. As do slate roofs. I inspected half a dozen homes in New Orleans area with real slate roofs, absolutely minimal damage. Again, hard to install correctly, heavy, and expensive. A good slate roof might last a hundred years with reasonable maintenance, which is longer than any other type of roof I have looked at.

As to installing a roof yourself, well this is no different than any other skilled trade, it is always MUCH HARDER than you think it is going to be, and the results on the first try are likely to less than optimal. As to saving money, how much is your time worth? If the answer is zero, and you don't mind suboptimal results, have at it. Personally I do a lot of my own work, but I never try to justify it by claiming I am saving money or doing a better job than a trained professional, I do the jobs because I enjoy the experience. I wouldn't touch roofing, too dangerous, too difficult, but to each their own.

Daniel as always your perspective is interesting and based on a great dealo of experience.

On the subject of warranty and marriages, that all depends on what side of the coin you are on, she for instance collected a bundle.......

The newer metal systems out there look better than asphalt when you ask most customers.

That not withstanding, good metal is an investment for certain.
Whether they last that long or not is a matter of many factors.....but even low end shingles have 30 yr warranty

Sure...and the paper they are written on is probably more useful for starting a fire than enforcing the warranty.

True....but it's not the shingles' fault or the manufacturer that roofers don't install them to the specifications in the warranty.....and I know that it is near impossible with some manufacturers to meet their warranty terms.

Is this a joke?

Please don't tell me that you think the primary reason for premature failure of shingle roofs is all installation issues.

We are getting ready to replace 2 roofs that are 10-14 years old and are installed well withing manufacturers required specifications.

Very few 3 tabs get installed around here anymore, but the only ones stocked carry a 25 yr warranty. I think there are some 20 yr shingles still available in limited color selection (black primarily) as special order.

I just looked at Certainteed's site and they only ship 25 and 30 yr 3 tabs to my area. Same shingles that used to have a 20 year warranty. Curious.

A lot of it depends on where you live. I've certainly seen many go this long or longer, especially in climates where it doesn't get excessively hot!

I'm just a homeowner, not a roofer.

I would never install screw-down metal roofing to a house. Only standing seam.

I would never install any roofing material over existing roofing material. I would always remove the old roofing to allow for sub-structure inspection and repair if necessary. I don't want to install a 50 year metal roof and not know the condition of the existing sub-structure.

IF they were installed within the manufacturers specifications, then I assume the roof is under warranty and that warranty would cover the replacement.

And no, I don't think the primary reason for failure is installation, but it is one cause and a pretty common one too.
