We had a problem with our shed workshop flat felt roof leaking and needed a quick repair.
How to repair a hole in roof felt.
For example soak the downhill side of a chimney first then each side then the top on both sides.
The ladder to the roof should have a stand off bracket so it rests against the wall rather than the guttering.
Alternately get more roofing felt and a tube of roofing caulk and glue felt patches over the rips with the caulk.
To make even minor roof repairs you must have an ordinary ladder and a roof ladder.
Make sure the caulk is rated for the temperatures and apply it liberally so you don t create a water pocket.
If a leak is difficult to find enlist a helper and go up on the roof with a garden hose.
The wheels allow it to be pushed up the roof without dislodging loose tiles.
Wind driven water that would normally flow down the felt and into the gutter instead drips onto the soffit and then back onto the ceiling of the room below through gaps in the felt.
From inside cut across the lowest part of the damage from rafter to rafter cut a piece of slaters felt 50 100mm wider than the rafter rafter size and taper this both sides slide the tapered edge into the cut and pin the sides to the rafters using lengths of batten.
Repairing felt around the eaves.
A roof ladder has rubber wheels and hooks at one end.
Start low soaking the area just above where the leak appears in the house.
Instead of replacing the felt roof we decided to use a product call.
Use a caulking gun to apply caulk to seal any holes that appear in the roof.
Isolate areas when you run the hose.
