Have a small flat roof over the porch (2m x 1m)...
Boarded with t&g & felted over...
Its started to leak in one corner ... no rot yet...
I was think of reparing with fiberglass mat (csm) & resin + gelcoat..
Should I remove existing felt first?
If not how do I prepare surface (brush off dirt & moss & loose
chippings & do anything else?)
If stripping felt ... can I put new resin & mat directly onto t&g or
do I need to cover with something first (thinking of groves in board &
also possible movement between boards with heat etc).
