Metal / Shingle, other Roof?
Ok, I bout a nice remodled 2000s/f mfg. home and it will be placed on my land next week. I am certain the roof will need to be replaced soon. I would love to put a red metal roof on it. However, I paid cash for the home, septic, getting the land ready, etc. and I don't what to spend money foolishly if I can help it.
In the long term, which would be better, metal, shingles, wood, etc.? Which would be cheaper to install of the three? the home is 27x68 w/about a 4/12 pitch.
If I do choose to use metal can I place it right on top of the old shingles or do i have to rip them off (please say I dont have to rip them off  )...
We are very excited about this house. He was recently outfitted with new Pergo Laminated, floating hardwoods, new vinyl tilt windows, marble bath room sink tops, new carpet, whoop whoop!!!
I also got two large Trex Deck 10x32 & 16x24 with a metal canopy and a 24' carport!!! whoop!
All for 25g!!!

Shingle tends to be the cheap solution and it doesn't last. Figure 20 to 40 years.
Metal is a little more to a lot more expensive and can last for hundreds of years. I like metal roofs for conventional construction.
Our roof is concrete. It is a barrel vault. I expect it will last thousands of years. See: Cottage | Sugar Mountain Farm

Looks like nice housing for the money, congrats!!
I don't know how the cost compares to shingles, but I will recommend a steel roof every time. DH worked for a "cold rolled" corrugated steel manufacturer for many years and that was GOOD stuff. We have some buildings we put steel on 20+ years ago and I bet you couldn't tell them from the "5 years ago" steel. You can get different patterns of corrugations and different colors to help you get the look you want for aesthetics. You can install right over the old asphalt shingle roof as long as the sheathing is sound. We have one old shed, we "temporarily" installed steel right over worn out cedar shingles and many years later, no problem, guess it wasn't a temporary fix after all.

You can overlay a grid of 1x4's or 1x6s and then anchor the metal to them. That is what we did. In the long run, metal gets my vote every time, even if you need to save up a little for it.
Not only that but if you plan any rain water catchment, sure is a breeze with the metal. Our 30 x 60 house, same pitch, ran us 1900 to put metal on it (labor our self). Just be sure, if you choose metal, to get an extra pound of screws or two.

I love my metal roof. I am so glad I spent whatever it was 13 years ago to have it installed. It rains a lot here, but I never worry. That is a great comfort, at night when it is pouring and you know your roof is solid. AND won't catch on fire!

Right now, there isn't much price difference between shingles or metal. I'd go with metal. Make sure there is no damage to the roof, and make sure you have a ridge vent.

Just a suggestion but I would think of putting the metal roof above the structure kind of like a shed, mobile homes tend to run on the warm side and this provides shade for the house and protection.

I have to agree with everyone else - I have a metal roof and I love it! - we put 2X4 stringers with bubble insulation and use less heat and can't even hear it raining.

My brother is a contractor, and he and my husband just put a metal roof on our double-wide. They screwed it directly onto the old shingles. They pulled all the old vents off and cut a ridge vent and just screwed it all down.

On a home I previously owned I wanted to put the painted steel over shingles . I contacted the manufacturer of the steel roofing & asked how I should do it . They said just put roofing felt over the shingles & screw the steel roofing down over the felt . That's what I did .
I have read on other forums that there is a problem with condensation rotting out wooden stringers if done that way & also that you can't use treated wood against the steel roofing .

Metal roofing is generally more energy efficient.

A lot of people think those stringers or strips of lumber make the steel more secure, but it really doesn't. And if you put the stringers down with nails, forget about it. We have a complete 12 X 24 roof to a shed in the pond over on the next property because the nails on the stringers pulled out but the steel that was screwed to them held together, and the whole thing sailed a half mile away in a bad storm.
If you are putting steel on a barn or shed that has no sheathing, then you need the stringers. But if there is good sheathing, you don't.
Make sure to put the trim on the side edges so they are secure. The top edges are secured under ridgecap. Then just the bottom edge is vulnerable to wind but with just a small "drip line" like 1/2 inch and a line of screws near the bottom, it isn't going anywhere.

4/12 roof pitch is about as flat as you want for a shingle roof. They don't last near as long as a 6/12 pitch. This makes it even a better reason to go metal roof. Lots of them are put on over shingles....but.... If there is more than 1 layer I wouldn't. Mobile home roof framing is weak to start with and in high snow zones it can be a problem, a lot of weight up there. If over existing roofing, yes tarpaper under the metal, make sure the screws are long enough to get a good bite into the sheathing....James

Metal is much easier for aving your rain water collection. None of the shingle stuff, those itty bitty bits, to deal with.

My Mom had a metal roof put on her home and says her electric bill dropped significantly (and it looks SO nice!).
If I could afford it right now, I'd do the same.

In some areas you are not allowed to have 2 layers of roofing. Check your codes before installing the roof.

I'd strip it if your going to put metal on, that's the right way to do it. Metal will be quite a bit more, but for some it's easier to put down. The panels aren't too badly priced, but the extras are the expensive part. To me it's a toss up, I don't like the look on metal on a house' it's a barn/shed material. For me I can put down shingles just as fast as meal with a nail gun.
PS if you go with metal put longer screws in that they call for, I've seen a lot of them work their way back out.

In the Deep South, you're lucky to get half that life with shingles. The hot sun really tears 'em up. We're going metal- it matches the local places here in SC, and with a little luck, I'll never have to go up on the roof again!
