saggy roof

[Matt]

I am purchasing a 3 year old singlewide that need some work, but one thing that I am hoping not to have to do is roof it. It looks like all of the sheets of fiberboard between the beams are sagging. it is a regular pattern across the length of the home. they are 4 or 6(ish) feet apart. I have been told 2 things. one is that the beams are just so far apart that they are going to sag over time and the other is that it is probably water damage and needs replacing. does anyone have any idea what I am referring to and does it indicate water? it just seems strange that it would be so regular and pretty much the whole roof.

bare with me here...are you refering to the roof itself or the ceiling? when you say fiberboard im thinking ceiling....what types of repairs are you having to do in a three year-old home? any water damage(floor replacing)?...

Boy am I glad I found this site- if for nothing else but to know I am not alone!

Our house is older (much-1989) but we have the same problem with our roof. It seems like they did not put the rafters close enough together to support the roof itself. It scares me to death but my husband the optimist says not to worry about it because it doesn't leak. To make matters worse the previous owner had a roofover done so we have the weight of 2 layers of shingles on ours.

I would love to know any fix for this outside of tearing the roof off, adding rafters and re roofing.- Melanie

Usually the ceiling is opened up and the damaged wood is either removed and replaced or new wood is sistered up to shore up the old. Generally water damage has caused the damage, but not always. Weight issues can cause the damage also, too much snow, or the added weight of a roof over can also contribute to it. Tom

some manufactures cut cost o "low-end" homes buy using a reduced plywood sheathing HUD requires at least 1/2 equilivent sheathing the actual thickness in some cases is 30/64...which will sag under heavier loads even at 24 inches on center these roofs are designed for the shingle load from the factory ..."we will not do an overlay on a home"....the best thing to do is ,when you need the new roof ..spend the extra money have the shingles torn off,if the sheathing is good it will be fine....if the extra weight has made it warp then its best to have it torn off and replaced with 5/8 plywood sheathing and this way you know your getting at least 1/2 ..measure the thickness if you have to....ITS YOUR MONEY!

there is no water damage on the inside. when i said fiber board, maybe I should have said particle board.

probably doent have plywood clips either

I have been searching the web for new ceiling panels. The roof in my single wide home sprung a leak.My husband fixed it,but now we are stuck with water damaged panels.Can anyone tell me where to look for these panels. Thanks.

[Danny]

do you have a mobile home supply store near you ...you cn try them but alot of the supply houses won't carry them because they break too easy...if that doesn't work then you can try a dealer they may would order you some .

I have same problem. '72 double-wide major roof leaks in the past. The ceiling old panels are stained and 2 or 3 major warp (sags). I had the leaks repaired. I want to improve the looks but cost is a problem so need to be creative.
A friend suggested nailing on some lightweight wood strips to the ceiling, then nailing lightweight enxpensive wall panelling onto that, and then painting. Would this work or be too much wieght to hold? I don't know that there's much wood up there to nail to.
My second is using large sheets of styrofoam. Could I glue or somehow tack styrofoam onto the existing ceiling (then paint)? Any thoughts, ideas, knowledge shared is appreciated. thank you.
