crack in the ceiling is spreading and afraid


i have a question about the construction of the roof. Right now the vaulted roof is made up of 7/16 sheets of whatever they use and i am also told its 2x4 framing. If i went with more than 1/2 in sheeting, say 5/8, am i going to be in trouble structurally? I am thinking of the additional weight being a problem even though I would like to upgrade. The contractor seems to think its all good but I'm not so sure. WOuld like your thoughts? I haven't heard back from the insurance company yet to see what will be covered. My biggest concern is that they are looking at one section as a previous problem that wasn't addressed in a timely manner. The part were the wall is "buckled" or "popped out. They say it is in pictures from 2008 as the same way as it is today so why the urgency now is the feeling I'm getting from them. Have I made a big mistake? Regardless, there are more issues than that one area but i am concerned now....

I roofed a double wide a couple of weeks ago.The trusses were some type of engineered type.They were a "2x2" spanning about13' or so.It seemed the spacing to center on the "2x2" was 12"-14".I replaced some decking and it also was 7/16" O.S.B.Those trailers are manufactured to a certain spec.A Structural test was performed in the design then the manufacturing of your home.A double wide has different spec's for load bearing than a house on a foundation.It is your home but I would consult an engineer before I replaced all the plywood with something other than the manufacture installed materials.

If you think about it,you are wanting to add some sturdy thicker structure above your head,but want to leave the support for the roof the same.I feel if you look at it that way you might have your answer.

ok, been a couple months and I am at the point that the insurance will cover some costs because it was due to the ice damming and water so i am moving forward with a "new" roof. Contractor is starting this week, if we can get a couple days good weather, western ny is infamous for cold, wet stuff this time of year. anyway, as you are aware, this is a mobile home 16x76, gabled roof. the rafters look like 2x2's then the sheets of wood on top of them are 7/16, i am told, of pressed board. i am having a "tear off" done-ok...1. does this mean only shingles or does it mean those sheets of pressed board as well? the reason i am asking is because i thought the sheets were getting "tore off" and 5/8 plywood is going to be used then a rubber thing, then 40 yr shingles. he talkes about the ice and water shield which is going to be added and some other stuff that sounds good, considering the area i live in... ridge vents extended maybe. i don't know off hand. \\ ...ok 2. if the original pressed board sheets are covered with the rubber stuff,(not sure if its a certain amount of feet up from the edges or the whole thing) and the 5/8 in plywood, is this standard practice? i thought the 5/8 was replacing the 7/16 pressed board that is up there. And it does need replaced, it has dips and valleys and is "squishy in spots. leads me to 3... what is the code? standard weight that should be on the roof. i don't want a bunch of extra weight on it well knowing that winter will be here again. believe me, i am right in a snow belt area, go 10 miles up the road and out of it but the lake effect snow is "evil". then, #4. how do we add the insulation if the pressed board is not lifted? i do have some pics and i will try to figure out how to attach them. but thinking i should get going with these questions. one other is that i was initially quoted with the 5/8 board...but i really think it was after tearing off the 7/16th and now the talk is to not do that part... i'm just wondering.. which way is better and, of course, which way is less work/expense. i do want to say that i trust this contractor and him and his family have been doing this for years. but i just want more info, second opinion on things. i don't know if he is really familiar with the mobile home stuff as much. thanks again, so much help here with all the "projects" i have done.

i am freaking out.... no way is that pressed board staying on there... no way......and i even have to question the 5/8. i wouldn't be afraid of 1/2 in as bad, that is pretty close to 7/16.... but definatley not both. and is there a way to "beef up the supports" i thought of sistering the trusses but that doesn't make sense, it would have to come from below.....

posting an update.... insurance claim was filed and the claim approved. The contractor is working with me and i am getting my roof replaced as well as interior work. as it turns out the rafter was not broken but the drywall was. i do have a roofing question now though. like i said this is a manufactured home ( not mobile home after some 1990 something), it has the "vaulted" ceilings/roof. they are tearing off to the decking and putting new decking on top of existing. was told that you can't take off the original decking or the framing would fall apart or something. there were valleys in the old and obviously the water damage but they are covering this. they are adding the ice/water shield to cover the whole thing making sure the soffats and ridge venting is good. i was told this shield is also considered a "rubber roofing" but i don't know. are there different brands of this with "rubber' in it? and also i'm wondering about vents to hot water tank and furnace lining up right with the added height of the roof even though it is small. ideas?
