Frequently asked questions
Why does my roof only leak in heavy rain?
Wind-driven rain finds gaps that ordinary rain does not: lifted shingle edges, worn flashing at chimneys and walls, and valleys where water runs faster than the underlayment can shed. These are usually repairable if caught early.
Is a ceiling stain always a roof leak?
No. In Victoria winters attic condensation, a bathroom fan venting into the attic, or an upstairs plumbing issue can all stain a ceiling. Mark the edge of the stain and watch whether it grows after rain.
How fast does moss damage a roof?
Light moss is cosmetic; thick moss holds water against shingles, lifts edges and can take years off an asphalt roof. In shaded Greater Victoria neighbourhoods, treating every 12–24 months is common.
