Having my slate roof replaced and it's not as painless as I was led to believe. A number of things seem to have been overlooked or botched, the main consequence being it raining into my loft and then into my daughter's bedroom yesterday. That's another story...my query for now is about the effects of a lot of rain falling onto the exposed membrane below. It's now 4 days that my roof has been without tiles, during which time a fair amount of rain has fallen, often heavily.
I understand that the membrane is there to carry water away, but is this true for heavy, persistent rain too? Will its performance/lifespan have been affected by being exposed for so much longer than it should have been?
