JD our roof expert should be along soon, but I would try to find a way to get sealed at least untill warmer weather.
On the plus side at least you know there is a problem BEFORE the ceiling goes up. Greg

Hi and welcome to the forum,

I lived in Seattle for many years and been in B.C. many times. I would certainly think that it is too cold right now for any of the elastomerics to set right now. Rubber coatings can go on in the cold, but it could take a month to set in real cold weather. A lot of things could happen to uncured sealant in a month.

If you can isolate all of the leaks, you could use an asphalt wet or dry type mastic as a bandaid. But this is the wrong sealant to use on a metal roof. It would just get you through to better weather and that stuff is a bear to get off. It really should be thoroughly cleaned off beyond a trace, before applying any "white" sealant.

I don't know if you have a single or double wide, but you could buy the 16' x 100' heavy plastic to cover the roof for now. You would need to open small slits to be able to push your roof vents through and then tape the heck out of it. Of course plastic wood not survive a wood stove chimney, but should be OK on appliance vents. I will fasten them down along the top ot the walls using strips of wood. 3/8" cdx plywood is cheap when cut into 2" strips on a table saw. I "under-roll" the wood a few wraps into the plastic so the folds are in next to the wall and not on the outside catching water. Not pretty and a big storm could take it off. Kind of depends on your weather. People get by with all winter here in Fresno.

Hi,
Need you to be a little more specific. The nature of your problem, are you asking about removal of the attic space plastic and insulation?


Harry
Once you get the roof sealed up as per JDs previous instructions I don't see why you can't start on the inside.

Thanks.

Hi lar3140,

Kind of depends on how much of the insulation is wet. It is is just spots of fiberglass batt insulation, I would just work on the wet areas. Cut the plastic down the middle of a truss to make it easy to staple back up. Make a flap to get the wet insulation out, replace the insulation and add a patch of plastic over the cut. Be sure to overlap the plastic quite a bit.

If this is the blown in loose insulation above visqueen (plastic), I would pull it all out, only because batt would be easier to work with. The loose insulation is good stuff, but hard to replace just a little. You would kind of have to make that judgment call yourself.

The loose blown insulation also tends to hold the water longer and is more apt to warp the ceiling panels.

just started taking insulation out. correct me if im wrong but the metal roof is all wet. i think it is just condensation. if i put insulation back thinner stuff so there is a gap between insulation and roof will that help and then maybe in spring put in a few roof vents
