I have a lean to rosemary tiled roof on the kitchen...approx 10ft long, 3ft high
Its fairly shallow - maybe 30 degrees and has been redone last year by my a local roofer who replaced the tiles, added new batons, new DPM and flashing.
Up to now its been fine but we have been battered by westerly winds the past couple of days and consequently the rain has been coming in the kitchen.
I cut a hole in the kitchen ceiling as the water damage was pretty bad so I could take a look and stop it spreading.
The water is coming in on a 2 foot section of the roof and the water appears to be trickling down the exterior cavity wall on both sides.
The DPM is bone dry throughout as is the rest of the roof apart from this one section.
I'm thinking its possibly rain being driven under the flashing but can't figure out why it would be only in one section.
I'd go back to the lad who fixed it but he's in a bad way with covid.
I've done the usual googling about lead sealants etc but would welcome some real advice
I got up on the roof this morning and lifted the lead flashing a couple of mm and water was released from under the flashing
Any advice would be most welcome...
