Rain & Moisture Resistance
Synthetic slate is particularly interesting for Vancouver because many polymer-based products absorb very little water compared with organic roofing materials.
- ✓Low water absorption
Polymer-based synthetic slate is designed to resist moisture absorption and moisture-related deterioration.
- ✓Water-shedding profiles
Some systems use interlocking or overlapping designs to help direct rain away from vulnerable roof areas.
- ✓Underlayment still matters
Synthetic slate works as part of a complete roofing assembly; it does not replace quality underlayment and flashing.
Persistent rainfall makes water management one of the most important considerations when selecting and installing a roof.
