Low-slope roofing needs a continuous water-resistant system and carefully detailed drainage, penetrations and perimeter conditions. The correct membrane depends on the building and existing assembly.
Where This System Fits
Low-slope roofs are common on commercial buildings, multifamily properties, modern homes, additions, garages and mixed-slope buildings.
What We Evaluate Before Installation
We evaluate existing membrane type, substrate, insulation, drainage, ponding evidence, parapets, scuppers, drains, rooftop units, penetrations and repair history.
Installation Details Matter
The material name alone does not determine performance. Edges, transitions, penetrations, flashings, drainage and substrate conditions must be compatible with the selected system and installed as a complete assembly.
Repair or Replacement
A localized defect may be repairable when the surrounding system is in serviceable condition and compatible repair materials are available. Widespread deterioration, repeated leaks or substrate problems may justify replacement.
Important Considerations
Calling a roof “flat” does not mean it should hold water indefinitely. Drainage and slope remain part of system performance. Material compatibility is also critical when repairing older membranes.
