Our bach roof has leaked off and on for 3-4 years, depending on what direction the rain is coming from.
It all started when the conservatory was put on ….. so first the plumber, then the builder, then my turn … we all pulled off flashings and gunked every possible source of the leak.
Each time we thought we had fixed the leak but soon it was out with 2 buckets and towels.
Expecting we may need a new roof we called back the builder.
Hooray for F, he’s our hero!
He found 3 teeny holes where the tiles had been nailed down in new holes each time.
Now we are drip free!
