What BC Homeowners Are Saying

"Our 18-year-old asphalt shingle roof was losing granules badly and we were quoted $22,000 for a full replacement. NanoShieldBC came out, did a free inspection, and recommended GoNano roof rejuvenation instead. The difference is unbelievable — the shingles look restored and the moss is completely gone. Saved us over $18,000. Highly recommend to any Surrey homeowner."

"I had thick moss covering the north side of my roof in Langley. NanoShieldBC removed it all manually — no pressure washing that would damage the shingles — then applied the GoNano Bio-Boost™ treatment. It's been two months and zero regrowth. The team was professional, on time, and cleaned up perfectly. Worth every penny."

"After the rainy season my roof looked terrible — granules in the gutters, shingles drying out and cracking at the edges. A neighbour recommended NanoShieldBC and I'm so glad I called. The GoNano treatment restored the flexibility to the shingles and the roof looks years younger. The whole job was done in one day. Excellent service in Abbotsford."

"Our cedar shake roof in Burnaby was greying and starting to show moss. We were worried about rot. NanoShieldBC treated it with the GoNano cedar formula and the difference is remarkable — the shakes look revived and the water beads right off now. They were honest that our roof still had good life in it and didn't try to upsell us on anything we didn't need."

"I manage several rental properties in Coquitlam and have used NanoShieldBC on three of them now. The GoNano roof rejuvenation treatment is the best investment I've made in my properties. Each roof that would have needed replacement in the next 2–3 years now has another 10+ years of life. The cost savings across my portfolio are significant."

"North Vancouver gets so much rain and our roof was covered in moss every year. NanoShieldBC did a thorough moss removal and applied the GoNano treatment. The team explained exactly what they were doing and why — I appreciated the transparency. Our roof looks clean and healthy and they gave us a written treatment record for our files."

"We were preparing to sell our White Rock home and the roof was a concern — it was 15 years old and showing its age. NanoShieldBC treated it with GoNano and it looked so much better that our realtor commented on it during the listing photos. We avoided a costly replacement and the home sold quickly. Fantastic service."

"I was skeptical about roof rejuvenation — it sounded too good to be true. But after seeing the before-and-after on my neighbour's roof in Delta, I booked NanoShieldBC. The GoNano treatment genuinely restored the shingles. They're flexible again, the granule loss has stopped, and the moss is gone. I'm a believer now. Saved me $20,000."

"Our Vancouver home has a north-facing roof that gets moss every year without fail. NanoShieldBC's moss removal was thorough and professional — they didn't just spray chemicals and leave, they manually removed all the growth first. The GoNano Bio-Boost™ treatment has kept it moss-free through the entire rainy season. Exceptional work."

"NanoShieldBC treated our Burnaby home's roof last fall and we've been through a full BC rainy season since. The shingles are holding up beautifully — no new granule loss, no moss, and the roof looks years younger. The team was professional, arrived on time, and the price was very fair compared to what replacement would have cost. Strongly recommend."

"We have a large home in Surrey with a complex roof. NanoShieldBC handled the entire job in one day — I was impressed by how organized and efficient the crew was. The GoNano treatment has made a visible difference and we've had zero issues through the rainy season. The free inspection and honest assessment before booking gave us real confidence."

"Our cedar shake roof in Maple Ridge was in rough shape — grey, mossy, and we thought we'd need to replace it. NanoShieldBC's inspection showed the shakes were structurally sound and a good candidate for GoNano treatment. The result exceeded our expectations. The cedar looks revived and the water repellency is remarkable. Saved us $30,000."
