Dormers on St. Mellons Properties

A dormer is a small building standing on a roof, It has more junctions per square metre than anything else on a uniform interlocking tile covering: a flat or pitched top, two cheeks, a front, and a line where the whole thing meets the main slope. Every one of those junctions is a place persistent damp off the levels can get in.
What This Covers
- Dormer leaks
- Flashing defects
- Dormer roof coverings
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
Where Dormers Leak
Almost never through the middle of anything, and on these late-twentieth-century estate roofs almost always at a junction. On a uniform interlocking tile covering the leaks are at the cheek-to-roof junction, the flat top's upstand, the soakers down the sides or the window itself. With low-lying, sheltered conditions, rain gets at all of them from the side rather than from above.
Working on a Dormer

A dormer sits mid-slope with nothing flat around it, so with access flat, with driveways and room almost everywhere it usually needs a scaffold to be worked on safely. Because the same failures repeat across whole streets, it is worth dealing with the whole dormer while the access is there rather than returning for the next junction.
Doing the Junctions Properly
Cheeks re-covered or re-clad, soakers interleaved with the covering on these late-twentieth-century estate roofs, the top re-laid with a proper upstand and the whole thing flashed into the slope. On a uniform interlocking tile covering that is what stops a dormer leaking; anything less is sealing a symptom. With persistent damp off the levels, mastic at a dormer junction is a winter's grace at most.
