Hi all,
Our house is a 1950's linked semi, a house attached on one side, on the other our garage attached to a neighbours garage (over which they've built a two storey extension).
We're putting a rear extension on and looking to bring the pitched roof round in an L shape over the length of the existing garage (using hip roof) to replace existing flat roof.
Now, if we go for a pitch over the garage, the lower edge will need a gutter and also tying in to next doors extension. I have seen this done whereby the gutter sits on top of the wall and then felt or similar is laid underneath the gutter and tied in to a course of mortar on the neighbours extension.
My questions are: 1) is this the best method? 2) Anything else better to use in this instance than felt?
We have some concerns around damp penetrating between the two 'garages' (the rear half of both will be occupied by living space) via the gutter and felt approach.
I have attached an illustration, the red line indicates the position of our proposed roof line - hope it makes sense!
Thanks in advance for any comments/suggestions.
Chris
