Professional soft-wash moss and lichen removal. No pressure washing — we protect your tiles while eliminating the growth. Covering Bishop Auckland, Shildon, Spennymoor, Coundon and the surrounding area.
Professional soft-wash moss and lichen removal. No pressure washing — we protect your tiles while eliminating the growth. Roof cleaning from £300 depending on size. Free surveys.
Low-pressure application of a proprietary moss-killing solution. Kills moss, lichen and algae at the root without tile damage.
Gentle brushing and scraping to remove dead moss after biocide treatment. No pressure washing that strips tile coatings.
Manual clearance of accumulated moss from ridges, valleys and gutters where growth is heaviest.
Post-treatment biocide coating that inhibits regrowth for 3–5 years. Extends the time between cleaning treatments.
Combined gutter clearance as part of the roof clean — dead moss washed into gutters is cleared at the same time.
Annual or biennial maintenance visits to keep the roof clear long-term at a lower cost than a full clean every few years.
Bishop Auckland's housing stock is predominantly Victorian and Edwardian town centre terraces with Welsh slate; post-war semis on estate fringes with concrete interlocking tile. Understanding the specific roof types and their failure modes is what separates a knowledgeable local roofer from a national firm that sends whoever's nearest.
Elevated position with significant westerly exposure — mortar bedding and flashings fail faster here than in valley towns. This directly affects how quickly specific roofing problems develop and which repair approaches last longest in local conditions.
Wind-driven mortar ridge failure on exposed west-facing slopes; lead flashing damage from wind uplift; nail sickness across post-war estates. We attend these jobs regularly across Bishop Auckland and carry the most common materials on the vehicle to avoid return visits.
Industry-recognised quality and safety standards.
Written workmanship guarantee on all work.
Fixed quote before we start. No surprises.
We get on the roof before quoting. Always.

Moss and lichen growth rate in Bishop Auckland is driven by three factors: slope orientation (north-facing slopes get less UV), shade from trees or adjacent buildings, and local humidity. Wear valley position with westerly exposure from the pennines — higher rainfall than the tees valley and more frost days, accelerating mortar and lead deterioration. Properties in Bishop Auckland that face north or sit in the shade of mature trees accumulate moss significantly faster than equivalent south-facing exposed properties. For these properties, a shorter treatment cycle of 2–3 years is more cost-effective than waiting until growth becomes heavy.
Pressure washing is not a legitimate roof cleaning technique on any Bishop Auckland property. It strips the protective aggregate surface from concrete tiles, forces water under tile laps, and often dislodges loose tiles on roofs with advancing nail sickness — a common condition on Bishop Auckland's post-war housing stock. We use soft-wash biocide treatment as standard — applied at lower pressure than a garden hose, it kills growth at the root without mechanical damage. The growth dies and detaches naturally over 4–8 weeks.
After soft-wash biocide treatment, an anti-moss inhibitor coating applied to the tile surface significantly extends the period before regrowth establishes. On a standard property in Bishop Auckland, treated and then coated, the growth-free period extends from the typical 3–4 years to 5–7 years. For properties in Bishop Auckland with persistent heavy growth driven by wear valley position with westerly exposure from the pennines — higher rainfall than the tees valley and more frost days, accelerating mortar and lead deterioration, this combined treatment programme is significantly more cost-effective than repeated reactive cleans.
Pressure washing strips the protective surface aggregate from concrete tiles, shortening their lifespan significantly. It also forces water under tile laps and into the roof structure. We use soft-wash biocide treatment — lower pressure than a garden hose, applied with a surfactant that kills the growth at the root over 4–8 weeks.
The biocide kills moss and lichen over 4–8 weeks following treatment. You'll see the growth turn brown and begin to detach naturally. A follow-up brush clean can be done once the growth is dead if you want a faster visible result.
Yes, noticeably. Heavy moss is one of the most visible signs of deferred maintenance to buyers and surveyors. A clean roof improves kerb appeal and can head off survey comments that reduce offers. It's one of the cheapest improvements relative to its impact on buyer perception.
