Stripping shingles from double-wide.

[Rossiter308]

I've got a lot of problems with ice build up on the mfg. home I live in. We get a lot of snow in this particular spot in Michigan and every year I'm up on the roof with a light snowblower clearing away the snow. If I don't we end up with water running down the walls, makeing a mess of the carpet and no telling how much structural damage done to the trailer. So I've decided to strip the shingles from the roof and peel the first six or seven feet of osb back from the eave edge. That way I'll be able to add more insulation all the way to the peak and also make sure there is plenty of air flow from under the eaves. Seems to be a little tight right now. I've done a considerable amount of roof work over the years but always when it came to stripping the old shingles off it was a job done with shingle nails. I'm a little concerned about the amount of extra time it may take with a stapled roof such as this mfg. home. I would appreciate some input from anybody that has done this kind of work and also is the idea sound as far as takeing care of the ice build up. I'll also be adding about four feet of water proof backing along the eaves. Thanks a lot.

You're on the right track. And it will be more time consuming stripping a stapled roof. You do have to be really careful about pulling up the OSB. It is also stapled and the top cord of the roof trusses is likely a 2 by 2 or 2 by 3, so you have to watch closely not to damage the trusses and the eaves. You also need to re fasten with at least as much fastening power as you removed in terms of shear strength. Ice and water shield should help a lot with the ice damming. If you add insulation, think about adding ventilation while you're up there. If the house is over 10 years old there aren't many vents at the ridge now. And you need more ventilation with more insulation. Adding ridge vents will improve the air flow from the eave upward across the bottom side of the decking.

Thanks for the prompt help on stripping the shingles from my double-wide. I did have a ridge vent installed. The Mfg. sent out a repair man after I sued them and got the job done. There is the required amount of venting under the eaves but the insulation is just to close to the roof sheating. I'm not sure but I think somebody recommended two and a half inches to get good air flow. But even then I figure I need more insulation. Got a furnace and a wood stove going all winter just to keep half ways warm. Thanks again.
