Leaking garage roof - temp repair

[Millwright]

Friend of mine has a leaky garage roof, we can't replace it just yet. It's a flat felt garage roof on ply boards. Could we pour and spread a few tins of black jack on it for the meanwhile do you think?

 

[Harry Bloomfield]

Yes, depending on where the leaks are.

Acrypol

Yes, depending on where the leaks are.

Mostly where some board joins are, I think expansion contraction over the years has torn the felt.

 

[Millwright]

Acrypol

Yes, but too expensive for a temp repair.

It will crack again

Umbrella?

 

[Millwright]

It will crack again

Yeah, but maybe by that time we'll be in a position to do something.

 

[Millwright]

Umbrella?

I've seen those, but again are expensive and need brackets drilling into the walls. Probably not suitable long term because of winds, but I think those roof umbrellas are only really for a few days if you're doing roof work in the wet?

It will, but you can mitigate this be embedding some ordinary scrim over the crack into the Blackjack or - better - Bostik Flexacryl. Won't last for ever but should see out the Winter until you can do something more permanant in the (hopefully) drier Summer.
