Somerset: Low-Pressure Roof Wash FAQ

​Q: My Somerset property has original clay tiles; can they be cleaned?

A: Yes, but we always advise that old clay is extremely fragile. While we use a professional low-pressure wash, there is always a slight risk of breakage with aged clay. However, if we assess your roof and find the tiles are too fragile for a wash, we will advise our "Scrape & Biocide" method instead.

​Q: Is there a risk of leaks during a low-pressure wash?

A: With any water-based cleaning, there is a slight risk of minor ingress if your roof has existing issues like perished underfelt. If we feel your roof is not watertight enough for a wash, we will recommend a manual scrape and biocide treatment to keep your Somerset home dry.

​Q: Why do my tiles look "sandy" or have black marks after the moss is gone?

A: This is due to years of organic growth. Moss holds moisture against the tile, which physically degrades the protective factory coating. Our low-pressure wash reveals the condition of the tile underneath, and the biocide treatment targets the deep-rooted black spots.

​Q: How long will my roof stay clean?

A: A professional low-pressure wash combined with our biocide treatment typically keeps a roof clear of moss and algae for 2 to 4 years.

​Q: How can I keep my roof looking "just-cleaned" forever?

A: We offer our Roof Care Plan. This involves a scheduled biocide "top-up" that kills new spores before they can grow into moss, ensuring you never have to pay for a full-scale roof clean again.

​Q: Is the biocide treatment safe for my pets?

A: As a safety precaution, pets must stay indoors during the application and for at least 2 hours after the roof clean is finished to allow the treatment to dry completely.
