Can pressure washing damage a roof?

Yes, high-pressure jetting close to the surface can force water under laps and strip the protective weathering off tiles and slates. That's why we use softwash and low-pressure methods rather than a straight pressure wash.

Is the biocide treatment safe for pets, plants and drains?

We're trained in spill management and apply biocide carefully to avoid run-off into planting, ponds or drains. If you have particular concerns about a specific area of the garden, mention it when you book and we'll plan around it.

What if my roof might contain asbestos?

We're asbestos awareness trained, so we know how to identify older roofing materials that may be a concern and handle the job appropriately rather than cleaning straight over it. Flag the roof's age when booking if you're not sure.

Are you insured for roof work?

Yes, we're fully insured for the roof cleaning work we carry out, including work from access equipment.

Left alone it doesn't stop at looking untidy. Trapped moisture works into laps and nail fixings, slates start to slip, and gutters fill with the grit that washes off as it rains. A proper clean and biocide treatment stops that cycle before it turns into a repair bill.

Everything is done from ground level or from access equipment — cherry picker or podium depending on the property — because walking a roof to clean it just isn't necessary with the right kit, and it's the single biggest cause of cracked and slipped tiles we get called out to fix elsewhere.

Victorian terraces and older slate roofs

Built as housing for workers in the former mining and steel industries. means a fair few roofs around Delves Lane are still on original or older-replacement slate, often with tighter, steeper pitches than modern housing. Slate handles moss differently to concrete tile — it doesn't hold growth in a rough surface the way concrete does, but individual slates can be brittle after a century of weathering, and any that are already cracked or slipped need identifying before we clean rather than after.

We survey older slate roofs closely before starting, work entirely from access equipment rather than walking the roof, and flag any tiles needing a roofer's attention separately — cleaning and repair are different jobs, and pretending otherwise on a roof this age is how small problems become big ones.

Hand-scraping tools

For roofs with thick moss cushions we use hand tools designed to lift growth without gouging or cracking the tile beneath it. It's slower than blasting moss off with pressure, but it's the difference between a clean roof and a roof with a dozen new hairline cracks.
