Hello, Another leaking bay roof! The downstairs bay window has a felt roof and when it rains heavily, the water is dripping constantly and fills a bucket within a few hours. Above the bay window is nothing except sky though on the next floor up is a window that is flush with the cavity wall of the house. One roofer wanted to replace the felt on the bay window roof (he didn't do any inspection). The second roofer wants to take some tiles off the roof of the house, re-felt there, attend to the flashing where the bay window joins the house, and also put 'Aquaseal' on the bay roof. It is expensive, whatever I do. Is this a familiar leaking scenario?
