I live in a "mobile home" in NYS. With zero degrees outside, I've got
icicles hanging down the sides of my trailer. Lost heat.
The roof domes up a little bit, in the center. Hmm. Airspace? Is it possible
to get a DIY cellulose blower, and pump in a couple bags of fluff to
insulate the roof?
I did a google search, but coulnd't find anything on the matter.
You might look into installing rigid foam insulation over your existing roof
and then EPDM. The best time to do this is when you could use a new roof
anyway (I don't know what shape your current roof is in).
Hope this helps,

If you have a metal roof covering it over will not help much.
You still have the air space below.
Blowing in insulation could create huge problems if you fill the airspace
Most mobiles are very long blowing in from each end is tough.
Re roofing can be done and is not that tough.
If you get trusses made you can do it yourself with metal roofing.
Put a nice overhang and a decent pitch that puts the new roof above the old.
Shingles would add too much weight.
You can work a panel at a time.
Leave the original roof trusses in place or you could end up with a structural
problem.. And install the new ones between them but you must remove the sheet
metal roofing itself to install the new trusses.
You can just hack off the roofing as it will be hidden under the new roof.
You can stick frame your own trusses but won't save much.
As you remove each old roof panel insulate and then install your new trusses and
metal roofing. You can do 4 feet at a time. It can go really quick if you have
Hard work, lots of metal to cut but will save you huge money down the road.
In some areas unless you can get an engineer to Ok this you will have to install
nasty posts outside your mobile right to the ground.
But a new metal roof with a decent 2-4/12 pitch can actually reduce snow load in
In a mobile, generally not enough air space to matter, and could cause more
problems than it solves, by trapping condensed moisture that now dries out
or has a place to drain. I'd recommend one of the double-roof systems,
where they glue foam to outside skin, and cover with preformed panels. Not
pretty, admittedly, but gives a much better R value.

Modern MH's already have insulation up there. You're going to have to
take a look to see what kind of space is left. And Home Depot (probably
other places too) will lend you a blower free if you buy _any amount_ of
cellulose. Your credit card has to be good enough, though.
When I had some floor up a couple weeks ago, it looked like it had about 1/8
inch of fiberglass on top of the tarpaper, or whatever was nailed to the
bottom of the floor joists. I'm not expecting to find much insullation up
Yes, I do ahve a credit card. And maybe if I have insullation, I'll have
less credit card debt.
Thanks for the good thoughts.
Just buy some styrofoam panels and put em up on the the roof, perhaps some
plastic sheeting on top of that so water dont cause a problem.........
Maybe hold it all down with some cinder blocks so the wind dont pick it

Depending upon when the 'mobile home' was built, there might be
insulation in there already.
My father had a 12' wide mobile home in DE with a lagoon out back. He
owned the home and the lot it was on. He had a gable roof built over the
top of it, and had that insulated.
Stormy, it can be done, and probably fairly easily. I have done such a
project. What you need to do is cut an opening in the very top of the
two end walls at the highest points and look in and see exactly what you
have in there. The one I worked on had about 3/4" at the most, and
absolultely none in spots. We got about 25-30 feet of 3/4" pipe to use
as a handle and taped the insulation blower hose to it. The guy stuck
the hose into the opening as far as it would go, and slowly pulled it
out, while moving it side to side to try and get as even coverage as
possible.I am sure they were not able to get 100% coverage, but they did
manage to get quite a bit of insulation blown in. I don't remember
exaactly how many bags it was, but it was a bunch. I made a HUGE
difference in heating and cooling. I hired that one done for $300 about
8 years ago. I am working on another one right now, and am going to try
to do it myself. I already checked and it also has nearly no insulation
there now. (about a 1972-3 14X66 approx) The only thing I am
planning to do differently is to use fiberglass instead of that chopped
up newspaper they call cellulose insulation. The fiberglass is much
lighter, and will not grow mold if it ever gets moisture. Both of the
ones I am talking about are over-roofed with "R" panel, so leaks are
less of a worry on them. The over-roof also helps on cooling greatly,
which is the main concern here in S.Tex. BTW, I have already checked
at HD and Lowes, and the only blown-in insulaion they sell is the
cellulose, and will lend the machine free with the purchase of the
insulation. I found the fberglass at a regular lumber yard for about the
same price, but will have to see if I can find the machine to rent at a
rental yard-- can't imagine it would be that expensive. Good luck.

Larry I recommend a different product.
Block filler or vermiculite FIRST.
Not to fill the space but to get down into the narrow spaces.
Just a couple inches.
If you can get a rope through both ends you can carefully drag a piece of carpet
to level and fill all the spaces down to the ceiling.
then blow in GLASS not paper. Paper will get ruined if you have any
condensation under the roof.
Last use the rope to try to get a nice even airspace between the fill and the
A careful installation of a fan blowing in one end sucking out the other will
help prevent problems.
OR even better add two wind turbines on the roof.
I have seen turbines alone reduce condensation and melting to almost nil.
I forgot to add we use the rope for this. With a sled made by curving thin
plywood. The sled drags along without hurt the insulation.
It's a bit hard to describe.
Others make fat wheels out of isoboard and roll the blower hose along.
