Roof Cleaning &Moss Treatment Shrewsbury

Shrewsbury has a moss problem. The River Severn loop creates a persistently damp microclimate that is among the most favourable in the Midlands for moss and lichen growth. North-facing pitches on Victorian terraces in Belle Vue and Monkmoor can accumulate a full moss covering within 8–10 years. Left untreated, moss lifts tiles, blocks valleys and retains moisture that accelerates surface decay.

Why Shrewsbury roofs grow moss faster

The Severn valley microclimate creates two conditions ideal for moss growth: persistent atmospheric moisture and limited drying time on shaded north-facing pitches. Properties near The Quarry park and the riverside walkways benefit from high tree canopy, which keeps roofs shaded and damp for longer. This is particularly evident in Castlefields and Kingsland where many north-facing pitches receive direct sunlight for less than two hours a day in winter.

Soft wash — the correct method for period tiles

High-pressure washing forces water under tiles, saturates the roof deck and can break down pointing on ridge and verge mortar. For Shrewsbury’s clay peg tile and Welsh slate stock, soft wash biocide treatment is the only correct approach. A low-pressure biocide application kills moss at the root, allows it to die back naturally over 2–4 weeks, and is followed by a light rinse. No tile damage, no structural risk.

What Shropshire Homeowners Say

★★★★★

"North-facing roof was completely covered in moss. Soft wash treatment in the morning, returning to rinse a month later. Completely clear now and they found two cracked tiles while up there. Great service."

Sandra P. · Monkmoor, Shrewsbury
★★★★★

"Had been quoted for pressure washing by others. These guys explained why that would damage the clay tiles and did the soft wash instead. Roof looks like new."

Ken B. · Castlefields, Shrewsbury
★★★★★

"Roof cleaning and treatment on a Victorian terrace. Thorough, professional, and the 5-year moss prevention coating means I won’t need to think about it again for a long time."

Lesley M. · Kingsland, Shrewsbury
FAQ

Frequently Asked Questions

Shrewsbury’s position inside the River Severn loop creates persistently higher atmospheric moisture than surrounding Shropshire towns. North-facing pitches near the riverside and The Quarry park are the worst affected, as tree canopy limits drying time and keeps surfaces damp.

In most of Shrewsbury, north-facing pitches near the riverside need treatment every 5–8 years without a sealing coat. A biocide treatment combined with a protective sealer extends this to 10–15 years. South-facing pitches in open positions may never need treatment.

Call 01743 537230 and describe what you've seen. We'll confirm whether a same-day visit is appropriate or book a survey within 2–3 working days. The surveyor accesses the roof, photographs the defects, and provides a written fixed-price quote the same day or the following morning. There is no call-out charge and no obligation to accept the quote.

Yes — soft wash is the only method we recommend for Welsh slate and clay peg tile, which are the dominant materials on Shrewsbury's pre-1950s period housing stock. High-pressure washing is not appropriate for these materials and we will not carry it out regardless of customer request.

Yes. Gutter clearing is included as standard with every roof cleaning treatment in Shrewsbury. While on the roof we also carry out a condition survey and report any defects requiring attention — at no extra charge.

No. High-pressure washing forces water under tiles, can dislodge pointing and saturates roof decks. For the clay peg tile and Welsh slate common on Shrewsbury’s period housing, only soft wash biocide treatment is the appropriate method.

In most of Shrewsbury, north-facing pitches need treatment every 5–10 years without a sealing coat. A biocide treatment combined with a protective sealer can extend this to 10–15 years. South-facing pitches in drier conditions may never need treatment.

A typical semi-detached costs £300–£600 for a full moss treatment. Detached properties are £500–£1,000. Free no-obligation surveys available.

Why Homeowners in Shropshire Choose Us

Honest Surveys

We survey every property physically before quoting — never from the ground or from photographs. If repair is the right answer we say so. We do not push replacements when they are not warranted, and we do not recommend repairs when replacement is the more economical decision over a five-year horizon.

Written Fixed Prices

Every quote is written, itemised and fixed before any work starts. No verbal estimates, no day-rate pricing, no additions once the job has begun without prior agreement. You know the exact cost before we lift a tile — and the price does not change unless the scope changes and you agree to it.

Our Own Team

No subcontractors, no agency labour. The team that surveys your roof is the team that carries out the work. We have been building our reputation in Shropshire since 2003 by taking direct responsibility for every job — something a contractor who farms work to subcontractors cannot offer.

10-Year Guarantee

All re-roof and major repair work carries a written 10-year workmanship guarantee issued at job completion. We are fully insured with £5m public liability cover. NFRC registered. We have been trading in Shropshire for over 20 years — our guarantee means something because we will be here to honour it.

Coverage Across Shrewsbury and Shropshire

We cover the full Shropshire area from our Shrewsbury base, with no additional travel charge for any location within our coverage area. The same team, the same standards, and the same written 10-year guarantee apply on every job — whether we are working in a Victorian terrace in Belle Vue, a 1960s semi in Harlescott, a period villa in Church Stretton, or a modern estate in Telford.

Our coverage includes all Shrewsbury suburbs — Bayston Hill, Meole Brace, Monkmoor, Belle Vue, Harlescott, Copthorne, Radbrook and Kingsland — and all surrounding Shropshire towns including Telford, Oswestry, Whitchurch, Newport, Shifnal, Wem, Church Stretton and Market Drayton. We also cover the villages and rural properties between these centres across all SY and TF postcodes.

Free surveys are available across all of this coverage area with no call-out charge and no obligation to proceed. Call 01743 537230 to book.

Before You Book: What to Expect

Every job starts with a free survey — not a quote over the phone, not an estimate from the ground. We access the roof, inspect the defect and its cause, check for related issues in the surrounding area, and photograph the condition. The survey takes 20 to 45 minutes depending on roof size and access. You receive a written fixed-price quote the same day or the following morning.

We do not use pressure tactics, we do not offer discounts for booking on the day, and we do not manufacture urgency. If a job can wait a week safely we will tell you. If it needs addressing quickly we will tell you that too — along with the specific reason why.

Payment is never requested upfront for repair jobs. For larger replacement work, a deposit of 10 to 25 percent covers materials, with the balance due on satisfactory completion. We accept bank transfer and card. We do not operate as a cash-only business.

Our Approach: Survey, Quote, Complete

Every job starts with a physical survey — not a quote over the phone, not an estimate from the ground. We access the roof, inspect defects and their causes, check for related issues in surrounding areas, and photograph the condition. The written fixed-price quote is issued the same day or the following morning. Survey visits are free across all Shropshire postcodes with no call-out charge and no obligation to proceed.

We do not use pressure tactics, do not offer day-of discounts to rush a decision, and do not manufacture urgency. If a job can wait two weeks safely we tell you. If it needs addressing immediately we explain exactly why. Every quote is written and itemised — no verbal estimates, no additions once work has started without prior agreement.

Pricing and Payment

All prices are fixed before work starts. For repair jobs under £500, payment is due on completion. For larger jobs — re-roofs, full guttering replacements, chimney rebuilds — a deposit of 10 to 25 percent covers materials, with the balance on satisfactory completion. We never ask for full payment upfront on any job. We accept bank transfer and card. Full VAT receipts are issued at completion on all work.

Any contractor requiring full cash payment upfront, offering large on-the-spot discounts, or approaching you unsolicited at your door should be treated with caution. Legitimate roofing contractors do not operate this way. If you are unsure about a quote you have received, call us on 01743 537230 for an independent assessment.
