We have a 16 degree pitch roof on a new extension. The roofer has so far installed Jewson breather membrane and battens. Concrete tiles to be fitted later.
One visible small hole is visible in the membrane. In addition during rain over the long weekend, three or four spots have let water in, one drip is more than just "spotting" too.
Is the membrane no good and should be redone, or is this adequate?
Before the work I'd asked the builder about having double membrane and he said we didn't need it.
Thanks.
Dave
