4. Valleys are tight and full of moss debris. This needs to be cleared. Esthetically, the roof would benefit from an overall cleaning of the moss on the face of the tiles. It is particularly bad in certain areas.

Customer:
Project Completed: n/a
Type of Roof: Concrete tile
Materials: n/a
Location: West Vancouver
Roof Analysis:The house’s primary steep pitch waterproofing is a concrete tile manufactured locally by Columbia Concrete Products. The style is that of a “shake”. Other roof systems include a standing seam metal roof system, an SBS membrane gutter system and various vinyl membrane patio decks. Cap flashing is consistent and appears to be installed appropriately. No systems were opened to inspect underlying components.
Issues of Note:
See photos above
Summary and Recommendations:
The tile roof system, and all others are acceptable for the relative age and common with the standards of installation at the time of original construction. The must-do requirements include plumbing vent upgrades, broken tile cover patches and valley cleanings.
