I woke up to my roof leaking right around the chimney pipe. I know I need a new roof, but I couldn't afford even to buy the materials this year to do it myself, much less pay someone else to do it.

I've got some large plastic (6 mil) sheeting (100'x25') which will cover the roof, and plan to hold it down with 1x2s.

This is an old mobile home with a certified* free-standing wood stove, and about 7.5' ceilings, and the stove pipe ends about 3' above the roof, with a metal "hat" (I don't know what they're called), and 1/8" wire mesh around the inside (I think this is a spark arrester?).

*"Certified" apparently means tiny fire box.

Questions:
If I put plastic right up to the base of the chimney, will there be enough heat to melt it or cause a fire?

With the wire mesh inside the "hat", would flying sparks be an issue?

Should I use some of that foil tape to hold it to the chimney, or duct tape, or not tape it to the base of the outside chimney at all?

Any and all thoughts welcome. I've got to get this done today, the weather predictions only get worse for the forthcoming week.

Thanks, Sue
