Shingles on the steep, membrane on the low-slope
Robert C. · Pasco County
The problem
The leak was not in the blue shingles. It was the flat. A big interior field with two turrets, draining onto steep slopes that were never detailed as a transition. Previous crew had shingled what they could reach and ignored the low-slope.
What we did
Two systems, one job. Architectural shingles on the steep perimeter and turrets. Fully adhered membrane on the low-slope center with real drainage, not a coat of silver paint. Transitions lapped the right direction.
The result
The white field in the photo is the membrane. The blue is the shingle. Robert has one contractor responsible for both, which is the only way a two-system roof stays honest.
Complexities on this job
- Steep-to-low transition is where Florida roofs leak. Shingles do not belong on a 1/12
- Two turrets — extra flashing, extra waste, extra days if you pretend it is a simple box
- Interior drainage. If the flat ponds, the steep never gets a chance
- Coastal-adjacent wind in west Pasco. Fastening and edge metal specced for that, not a Midwest book
