Roof leak - Qs about roof/ceiling construction
Posted: Thu Mar 15, 2012 11:16 am
I am new to the board - can't believe I haven't found this before now. Been Lonnie Dealing and landlording MHs for over 10 years now.
1973 singlewide, metal/metal. Tenant complains roof leaks: I seal, and pull down ceiling, drain and remove vapor barrier and insulation in the affected area, replace insul only, did not replace plastic v.b., put up sheetrock. This happens a few times over the next several months.
In pulling down the ceiling, though the roof is sealed, there is water beading up like crazy on the underside of the metal roof - I am guessing it is condensation since I did not replace the plastic v.b. Also, I noticed that there is apparently ceiling panel material between the rafters and the metal, but all soaked and saggy. Is this just a type of padding between the metal and the wood, or is it added to insulate?
I have opened up the ceiling above the electric furnace, so that it draws some ventilation through the ceiling area. I added vents outside at the ends up high (had one, added two more per end), I also cut about 4 holes in the roof and screwed and tarred plastic vent caps (all of this progressively to eliminate the moisture.
I am about to just put on a metal siding roof like this site shows, but I don't want to if I dont have to. Short of that, my guess is to tear out previously repaired ceiling, replace insul as necessary, and put a vapor barrier back up. But what about that fibered material between the wood and the metal? Do I need something there?
