Hi
I have a end of terrace property, constructed approximately 30 years ago, with a truss roof, and interlocking concrete tiles. The gable wall is topped with concrete coping stones, there is a lead flashing from the end gable to the roof, and another (drip) flashing which projects from the gable (side facing the roof) and stops any water dripping off the coping running down the face of the gable and behind the flashing.
A damp patch appeared in my daughters bedroom at the base of the roof on the inner face of the gable and in our room (same place)
So far we have:
1. Stripped the coping stones and relaid them.
2. Formed a lead flashing underneath the bottom three coping stones.
3. Checked the cavity for anyhting (mortar etc) bridging the cavity.
4. Replaced the drip flashing which had deteriated over the years with lead.
5. Re-visited the coping stones and re-cemented the cracks that had appeared due dry weather.
For a while theere has been no problems
Butt this morning after a night of heavy rain we had damp patches in both rooms.
Any ideas?????
