Why the process matters more than the price

The single biggest cause of dissatisfaction in UK roof cleaning is inconsistent methodology. One clean uses soft wash; the next uses pressure. One quote includes gutters; the next doesn't. One team fits scaffold; another balances on brittle tiles. That inconsistency is why we publish our process in full: so you can compare quotes against a known standard, not against marketing copy.

The 10-step process, in full

  1. 1Step 1

    Free inspection & drone survey

    Every job starts with a physical inspection — ground-level assessment plus drone imagery on any roof over 2 storeys or with restricted access. We photograph tile condition, ridge mortar, flashings, valleys and gutters, and note anything that will affect the clean. No obligation, no upsell pressure.

  2. 2Step 2

    Written fixed-price quote

    Within one working day you receive a written quote with a fixed price — no day rates, no 'if it takes longer' clauses. The quote itemises the clean, biocide, gutter clearance and any optional extras (ridge repointing, tile replacement, zinc strips).

  3. 3Step 3

    Job scheduling & pre-visit briefing

    Once accepted we book a firm date, confirmed by email 48 hours ahead. You'll receive a pre-visit briefing covering arrival time, water access, parking, plant protection and neighbour notification if terraced.

  4. 4Step 4

    Site setup & protection

    On arrival we sheet vulnerable planting, cover garden furniture, protect pathways and mask any nearby windows. Ladders, roof ladders or a MEWP are set up with proper anchoring. A pre-work walk-round photo record is taken.

  5. 5Step 5

    Manual moss removal (top-down)

    Working strictly top-down from the ridge, we remove bulk moss using profile-shaped scrapers matched to your tile. No wire brushes, no rotary tools, no high-pressure blasting on tile surfaces. Removed material is contained, not left to load the gutters uncontrollably.

  6. 6Step 6

    Gutter & downpipe clearance

    All gutter runs are cleared of dislodged moss, silt and leaf debris. Every downpipe outlet is water-tested. Photos of before/after gutter condition go into your job file so you can see exactly what was there.

  7. 7Step 7

    Soft-wash biocide application

    A roof-safe biocide is applied at under 500 psi across the entire roof surface, at the correct dilution for tile type and moss load. The biocide kills spores at the cellular level so growth doesn't return for 3–5 years, not just 12 months.

  8. 8Step 8

    Ridge, flashing & tile check

    While access is on site we inspect ridge mortar, chimney flashings and any visibly compromised tiles. Small issues are photographed and quoted; genuinely urgent finds are flagged before we leave the site.

  9. 9Step 9

    Site de-rig & final walk-round

    Sheeting is removed, planting checked, pathways cleaned, gutters flushed one final time. We walk the perimeter with you (or via a video call if you're not on site) and confirm you're satisfied before mobilising.

  10. 10Step 10

    Aftercare report & maintenance plan

    You receive a written aftercare report — before/after photos, biocide product used, treatment dates, and a maintenance schedule tailored to your property. We diarise a reminder for your next recommended treatment window.

What's non-negotiable

  • Soft-wash methodology on any concrete or clay tile — no exceptions
  • Physical moss removal before biocide, never chemistry-only
  • Gutter clearance included in every roof clean
  • Written before/after photo record with every job
  • Public liability certificate provided on request before booking
  • Fixed pricing — no day-rate creep once the quote is signed

Timing per property

Most Nottingham semis complete in a single day (7–9 hours on site). Larger detached properties and heritage jobs typically run 1.5–2 days. Bungalows are usually a half-day. We quote firm timings on every job so you can plan around us — no vague "sometime next week" scheduling.

What happens if it rains

Light rain doesn't stop soft-wash work — the biocide is designed to bond quickly. Heavy or persistent rainfall does. We watch the Met Office forecast for your postcode 72 hours ahead and re-schedule proactively rather than turning up and turning back. Re-scheduled jobs move to the next available dry window at no additional cost.

Frequently asked questions

Does following this process add to the cost?
No — the process is the standard we quote against. Nottingham pricing for the full 10-step service starts around £400 for a bungalow, £450–£950 for a typical semi and £900–£1,600 for larger detached or heritage properties. There are no add-ons for the process itself.
How often should the process be repeated on a Nottingham roof?
The full 10-step clean every 3–5 years is standard. We recommend a shorter-form biocide top-up every 24–36 months on shaded or tree-lined properties to hold results between full cleans.
Why doesn't the process include pressure washing?
Because pressure washing damages the tile surface and forces water past laps and flashings. Our soft-wash methodology kills moss and algae at the root, preserves tile life, and is the method specified by every major UK tile manufacturer.
How long do results from this process last?
3–5 years of visibly clean tiles for most Nottingham roofs, extending to 5–7 years of heavy-moss control when combined with a mid-cycle biocide top-up. We warranty biocide performance for 24 months.
