Peel and stick roofing

My daughter has a older mobile home she bought as a starter house a few years ago.

This past week she came to me and said she noticed the roof was leaking in the last weeks heavy rains.
My first thought was..... You have a husband!!!!
That's when she give me that daughter look; so I guess I need to fix her roof.
Yes I am a sucker for a daughters sad face.

Anyway I got up there this morning to see what I have.
It is a gable metal roof with about 3 or 4/12 pitch.
The metal has some (best I can describe it) rubber coating spread all over the metal.
This rubber coating is cracking and you can peel it up.

So I looking at my options.
I can get 29 gauge painted steel for .60 a sq ft. Time we add some 1x4 or 2x4 for purlins; some screws; ridge cap; we are at .85 a sq ft give or take a few cents.
So I will use .85 a sq ft as my base price.

I really would much rather use some flat roof roll roofing. No not the old torch down type but the newer peel and stick type.
I looked at the home depot and saw this for .42 a sq ft but then noticed it is really a underlayment.

So then I started searching roll roofing and see most of them are a 2 part system.
This about doubles the price.
The more I looked the more I got overwhelmed with the whole thing.

Then I noticed this (in link)a Menards. Yes the closest Menards is 500 miles away but I could order from a local Owens Corning dealer if I knew this is what I wanted.

So I am open to any and all ideas you guys may have on peel and stick roofing.

Thanks
But it is to late for a paint on coating
As I said the rubber coating over the metal is coming up
and would take any painted on material off with it.

What it really needs is a tar job but with the melting of the tar I am looking for alternatives.

I'd ask a mobile home dealer what they would use/recommend. The peeling rubber coating may not be original to the home, just someone's quick fix.

Just what do you plan on sticking the peal and stick roofing to? You replied to Gregg that roof coating wouldn't work, not just sure why, but then. If I was you I would want to isolate the leaking area first.
Sounds like you need to have a heart to heart talk with the daughter and her hubby and decide weather the trailer which must of had issues with the original roof and this steel roof was added to cure that problem, and then roof coat was applied to the steel because it started leaking, and on and on. You may just be throwing more good money after bad. You may have a problem with wind driven rain, not the roof surface itself.

I used that last year on our laundry room roof. We are still laying out towels when it rains. Ugh. I think I am going to tar over it if it ever stops raining.

Not sure what a heart to heart with my daughter will do as she does not know history of roof.
She bought this home for $5000 3 years ago and knew she would have things to fix as it is 25 years old.
With no house note she has a lot of room to work around upkeep expenses.
Still think she made a good deal for a starter house since the inside looks very well taken care of.

I know little to nothing about metal roofs on mobile homes but from what I have heard that paint on stuff is just to fill seam line leaks.
Do not know if this coating was added by previous owner to fix leaks are if it was factory installed.
Lets assume the P/O had the roof coated.
Well it has made its life time and is coming up.
Some pictures of the roof.













My hope was to get up there and remove any loose pieces and then treat it like a flat roof.
Just trying to explore all options before I commit to hot tar and tar paper layers.
I saw this peel and stick stuff for flat roofs on the internet.
It seems similar to the ice and water guard I have under my shingles on my house but made to go as a top coat with no shingles over it so I figured I would ask about it.

If it turns out to be not what I expected it to be from comments others make here I am going to get painted steel panels and just put a whole new roof on the trailer.
The more I figure up the cost the steel sounds better and better.

Thanks for any and all comments.

That just looks like most every mobile home roof I have even seen. BTDT many many times in the past and have pulled many a mobile home cross country. A good mobile home roof coating will seep under the loose stuff and seal things up if laid down nice and thick but yes if you can pressure wash or some other such thing to get the loose off your better off. Also keeping leaves etc off help the roof last longer since if left on water sits and then the roof rusts

I would find where it's leaking and repair the leak. Cool seal works after you find the crack in the metal roof. Wind causes the metal to flex. There will be a crack. Pella windows has a 4 inch wide aluminum over rubber tape to repair such leaks. Then Cool seal it. Try not to get on the roof. I'm sure others have the same tape. Go to a mobile home parts place, they will have it.

Where I live, single wide, metal roofed mobiles homes are no longer sold. No bank will loan money on a single wide or a double wide. Finance companies will at a higher rate. If they are older than 1987, you can't even get a permit to move one. Many insurance companies run away from them, unless you have been with them when you bought it new.

After seeing the pics., your best bet is to go to HF and buy tarps of your color choice and drape them over the roof, and hang gal clorox bottles filled with water from each eyelet. that will give your daughter maybe, another 3 months before it leaks again.
That roof is land fill material.
Loren, the Acg.

find the rafters, screw wood runners/strips to them and then put a tin roof over.. or deck and shingles. old roofing seal is coming up and unless you can get it off, new goop will probably leak in short order.

I agree to that.

"She bought this home for $5000 3 years ago and knew she would have things to fix as it is 25 years old."

At her $5K divided by around three year works out to only $150 per month for the home so far. She has already gotten her money's worth out of it.

If the roof has been leaking for a while it would be worth checking how wet are the insides of the walls and the insulation. Can they be dried out before mold problems set in?

John I would not waste the time and money with any type of roofing that has to bond to that old roof. The old roof is coming apart. The roof already has a gable line. I would farrow strip it and install NEW metal roofing. If the trailer is a 16 x 70 = 1120 x $.8 = $952 for a new roof that will last longer than the rest of the trailer.

Use a piece of metal or aluminum. Scrape the loose stuff off. Put a layer of tar over the hole. Use metal screws and attach the metal patch over the hole. How many places are leaking?

I'm betting you don't have real rafters under the metal. Good chance you have trusses made form 2x2's, staples and scrap pieces of wood paneling. Stay off the roof. Don't add additional weight. I've seen roof overs in Florida. I've seen a pole barn roof put over trailers in Indiana. They put post around trailer and make a roof like a pole barn's. That is done for older trailers with flatter metal roofs.

You can put a lot of money in roof you will never get back if you sell it.

John, I had a mobile home that hat a coating like that from the factory. Like someone else mentioned the metal rolls in the wind giving you a rumbling sound. I put down 1x4 purlins on 2' centers and put painted steel like you mentioned. It worked great and it lost that rumble sound. It sure cut down others noises as well. You just want to be careful stepping on the metal roofing without a solid sheathing. If you step on the ribs and not on the flats it will kink and make holes.

don't look all that bad for a trailer roof,don't get on it for any reason you can easily create more damage,from what I see in the photo take a stiff wire brush or equivalent attached to a long handle and remove the heavy flaking,then get some good quality high fiber cool seal and apply it using a brush with a long handle made for cool seal, don't be stingy with it apply a good heavy coat, two to the worst spots it will last a long time if applied right,that's what was used from the the factory on a lot of them,I coated a 16' x 40' that the 5V tin was in pitiful shape only had 1 small leak that plagued me until I found a nail hole that the cool seal made a ridge below it and during a hard rain it hold the water back enough to leak another smearing of cool seal over that spot and the roof held close to 10 years before it was replaced due to an addition to the building

So you think we should scrap the whole house because the roof is bad?

Thanks guys.
I have let my daughter read all the responses.
We have zero snow load but do have to worry about wind uplift once every few years.
With this in mind we decided...........

We have agreed that the roof is flacking and as mentioned the roof rolls in the wind; so anything that bonds to the original roof may be bubbling or coming up in short order. So cool seal or peel and stick is out.

She really liked the idea of decking with osb and then putting shingles.
That would cut down on the noise of living in a metal roof house.
It would only cost her about $1.10 per sq ft.
The only problem I have with it is putting that much weight up there.
If I was confident it would hold the weight this is the option we would take.
But since I am not confident the trailer would hold this much weight we would need to put in post and build a pole barn type roof over it driving the cost way up. The peek in the original roof also becomes a problem with putting in joist between the post.

So we have decided to furrow strip over the original roof and install painted steel over the strips.
This will allow her to pick a color she likes; hopefully a light color that reflects the mid day sun; let the metal run a few inches long giving her a small eve; and the metal roof will now outlast the house.
It could even stay up there in a move when she decides to upgrade to a real house one day.

She says to tell you guys thank you for the advise.
And for the naysayers she said...
Yes this may not be the best house but it cost me less than $150 a month to date;
And I can come up with way more than $400 cash on a moments notice;
And I am only 25 years old.
