I've been following the many posts about fitting roof vents, sealing them and reading with interest people who have had leaks and what they have done to reseal the roof vent.
Anyway, hole cut with jigsaw cutter, painted the bare metal edges with Hammerite, used plenty of IDL non setting bedding mastic to bed the roof vent into the hole, fixed it down with marine grade stainless self tapping screws. Cleaned the excess IDL from around the edges and ran a nice bead of Sikaflex 252 around the whole vent. Hopefully it's got a good seal now and not leak!
Fitting the second roof vent tomo.
Tackled the 2nd roof light / vent today. This one was to be fitted over the roof ribs. I made wooden fillers to fix into the ribs to give me a level all round surface to fit the roof light / vent.
Fixed the fillers with Sikaflex 252 and then used IDL mastic sealer to bed the roof vent in. Fixed with marine grade self tappers and a final nice bead of Sikaflex 252 all around the whole vent to give a good final seal.
