Question: roof is crooked and doors won't shut in cold weather
(Feb 13, 2014) Re-Posted with space after periods in the text: (3 hours ago) Joseph Matteini said:
It has been very cold 0 degrees plus or minus for a month. My enclosed front porch has sliding windows. slanting roof. The roof is higher on the left side above the doorway,making the door notshut evenly. The differencene is one inch. This is also starting on the inside door to the home. This has never happened before.This is an open porch of redwood and steps before the porch. It is an 1985 mobie home. HELP!
1. a sagging roof in danger of collapse - THIS IS UNSAFE and needs prompt attention; if this is the case you may need someone to rake snow off of the porch roof as well as to inspect for damage to the structure. We don't want the porch roof to fall in on you
2. A second possibility is that the roof structure has not sagged and begun to collapse but instead frost heaves have pushed up one end of the porch foundation. The hazards if this is the case are more subtle: there could be hidden damage to the floor structure - another collapse risk, or there may be just a trip hazard due to a sloped floor.
If the floor to the porch is level and has not changed, but the roof slope has changed then my first guess is more likely correct.
Watch out: doors that don't open or shut can be unsafe - you can be trapped in the event of a fire
Question: mobile home doors stick
(Feb 25, 2014) lisa kirshkaln said:
I too, like Joseph M. seem to be having a problem. I have noticed both my front and back doors are getting harder to close, the deadbolt in not inline anymore. and some of my floors and walls have separated by an inch or more, my ceilings seem to look like they are being jacked up in spots
. I do have an a-frame roof over the top of the mobile home.(metal) no snow build up. and some of my walls look a little slanted. I assume its from the frost heaves but what can be done. it has ruined quit a few walls and ceilings already. and do you know if home owners ins. would cover this type of problem. (my floors make noises now) I live in Maine, and we will still have some frost heaves for quite some time. thank you for any advice you can give.
Reply: frost heave movement in a mobile home, doors hard to open or shut - unsafe conditions!
Lisa it sounds as if your home is suffering from frost heave movement, and I speculate that with the current weather conditions this is not a time when actual repairs are possible. Here are some immediate concerns and suggestions:
1. Fire safety: be sure that you have working smoke alarms and that you can get the exit doors open. The worst would be to become trapped in a home, unable to exit, in the event of a fire.
2. Electrical and gas or oil safety: if building movement has torn or moved wiring or plumbing enough to break connections those systems could be unsafe. If you smell fuel odors and these can be trace to a gas leak it's time to get out and ask for emergency assistance.
If electrical switches or outlets or appliances that used to work start behaving oddly there is an electrical hazard - shut those circuits off and ask for help from a licensed electrician. There could be similar damage to plumbing drains that could be unsanitary, below the home, but those are less immediately life threatening.
3. Structural safety: when walls, ceilings, or floors seem to have moved, if movement has actually broken apart structural connections I'd be worried about a collapse.
I don't know how your home is built so can't have a clear opinion about how much movement would be dangerous, but in concept, if a floor starts feeling bouncy when it wasn't before, and/or if you could stick a finger into a space between floor and wall or ceiling and wall, a more expert assessment is pretty urgent. When the problem is a frost heave movement and there has been some structural movement it may be possible (and not so costly) to provide temporary support or to add connectors for safety.
Finally, yes contact your homeowners' insurance company and ask for an inspection and assistance.

Leaks at the windows of this mobile home led to water entry in its wall below the window.
The photograph (courtesy of Jeremias, some of our readers on mobile home restoration and renovation) shows severe structural rot to the floor frame structure below the leaky window.
Only a "do it yourself" repair was economically feasible in this case.
If you were not sure of the difference between modular construction and a mobile home, notice the presence of a steel frame chassis and even wheels located beneath your mobile home, doublewide, or static caravan.
Also notice that oil line on the crawl space floor. Is it leaking or vulnerable to damage or cold temperatures?
(HVAC) New York is in Thermal Zone 3
At below left our photograph illustrates a cable tie-down securing the mobile home's steel frame to a buried anchor (not visible) . At below right we point out a concrete septic tank that was mistaken for a mobile home foundation slab - do not park a mobile home on top of a septic tank nor over a drainfield or other onsite waste disposal sysetms.
