When this service matters
Flat and low-slope commercial roofs are systems, not single materials. Drains, tapered insulation, edge metal, and flashings decide whether water leaves the roof or sits until it finds a seam. We design, repair, coat, and replace low-slope assemblies with drainage as a first-class requirement — critical in Portland Metro’s climate.
Why Portland Metro & Vancouver
Ponding after atmospheric rivers is a metro fact of life. Our low-slope work emphasizes drain capacity, overflow paths, and chemistries that tolerate moisture when ponding cannot be fully eliminated.
What's included
- Low-slope condition assessment
- Membrane install and repair (single-ply and related systems)
- Drain, scupper, and overflow evaluation
- Edge metal and termination details
- Tapered insulation discussions on replacements
- Phased work for occupied facilities
- Maintenance programs after install

Questions about flat & low-slope systems
What’s the difference between flat and low-slope?
True zero-slope is rare; most “flat” roofs have slight pitch to drains. We design for positive drainage whenever the structure allows.
Can ponding be fixed without a full tear-off?
Sometimes with tapered crickets, drain work, or membrane repairs. Chronic structural flatness may need a larger replacement scope.
Do you handle both repair and membrane replacement?
Yes. We present repair vs replacement clearly when the deck condition makes either path realistic.
