A contractor has just laid a warm roof felt roof on my extension. I have noticed horizontal bubbles in top layer of roofing felt across the majority of the new roof. There was a delay in applying the final layer of roofing felt of 2-3 weeks due to bad weather. The final layer has been in place for about 5 weeks.
Please clarify if this is a defect and if so, whether it can be satisfactorily remedied without removal of the new felt roof, or whether the contractor should relay the whole roof.
Thanks
