Honest Roof Inspections & Professional Cleaning
We come out, take a close look, and tell you exactly what's going on with your roof — whether that means GoNano NuRoof treatment, cleaning, repair, or nothing at all. No upsell, no pressure.
What We Offer
Every service is backed by GoNano nanotechnology expertise and years of BC exterior conditions experience.
Roof Condition Inspection
A thorough visual inspection of your shingles, flashing, valleys, ridge, and soffits. We document granule loss, brittleness, moss coverage, and structural concerns — then give you a straight assessment of your roof's remaining life and whether GoNano NuRoof Fortify™ or NuRoof Revive™ treatment is a good fit. If it's not worth treating, we'll tell you.
Moss & Algae Removal
Manual and low-pressure removal of moss, algae, lichen, and biological growth that accelerates shingle deterioration. We use safe methods that protect granule adhesion — no high-pressure blasting. After cleaning, Bio-Boost™ treatment can be applied to prevent regrowth for years.
Fan Blower Cleaning
Included with every GoNano NuRoof treatment — high-volume air blowing clears all loose debris, pine needles, and granule buildup from the roof surface and valleys, preparing the shingles for optimal nano-particle penetration.
Debris & Gutter Clearing
Removal of leaves, pine needles, and debris from the roof surface and gutters — preventing water pooling, ice dams, and premature wear. Often bundled with gutter cleaning for a complete result.
Post-Treatment Inspection Report
After every GoNano NuRoof treatment, we provide a written summary of the roof's condition, what was applied, and what to expect over the coming years — so you have a record for your files and for future buyers.
