Moss thrives on Peartree's shaded and north-facing roofs. Peartree's century-old slate roofs suffer nail sickness, and the exposed stacks take the brunt of Midlands storms. Peartree's Victorian terraces share Normanton's tight terraced access, with rear work often needing careful scaffold planning. We clear it by hand and treat with biocide — never pressure washing, which harms the tiles.
Peartree sits under Derby City Council, and we handle the local permit side — scaffold licences and skip permits — as part of the job. Peartree's Victorian terraces share Normanton's tight terraced access, with rear work often needing careful scaffold planning. You deal with one local roofer, not a chain of subcontractors.
Pressure washing strips the weathering layer from concrete tiles, making them more porous and accelerating future moss growth. We use biocide treatment and careful mechanical removal on all Pear Tree moss jobs — producing better long-term results without tile damage. Any Pear Tree contractor offering pressure washing alone is not giving you the best long-term outcome.
On every moss treatment visit to a Pear Tree property, we include a ridge and verge mortar inspection. Heavy moss regularly conceals failing mortar beneath it — the moss holds the visual appearance of the ridge together while the mortar has lost its bond. Finding this during a treatment visit avoids a separate call-out and allows both jobs to be addressed in one scaffold hire.
Pear Tree's mixed Victorian and post-war housing sits on the urban fringe where industrial-era pollution has historically accelerated stonework and mortar deterioration beyond the city average. For roof moss treatment work in Pear Tree, the correct specification must account for these local conditions rather than applying a generic Derby-wide approach. We have carried out roof moss treatment work across Pear Tree and understand the specific requirements of the area.
All quotes in Pear Tree are free, provided in writing, and fixed before any work starts. Call 0133 240 5131 to arrange a free inspection. We typically respond to Pear Tree enquiries the same working day.
Biocide treatment only: £150–£300 | Full treatment + mechanical clean: £300–£600 | Mortar inspection: included | Combined with ridge repoint: best value option
Peartree's shaded, north-facing and tree-canopied roofs grow moss faster than most, and heavy moss does real harm — holding damp against the tiles and shedding into the gutters and valleys. Careful clearing and biocide, never pressure washing, is what protects the tile surface while solving the problem.
“Victorian terrace on the urban fringe — lime mortar used correctly, no prompting needed.”
“Ridge repoint and moss treatment combined in one scaffold hire. Best value.”
“Emergency call-out after storm. On site fast, professional, no fuss.”
When a Peartree roof starts giving trouble, the symptoms point the way. Moss thrives on Derby's north-facing and shaded roofs, especially near the Derwent and in tree-canopied suburbs. Heavy moss is not just cosmetic — it holds water against the tiles and blocks gutters and valleys. On Peartree roofs the warning signs tend to come early, because peartree's century-old slate roofs suffer nail sickness, and the exposed stacks take the brunt of midlands storms, so it pays to act promptly here.
You'll typically spot one or more of these:
When it is not the answer: If tiles beneath the moss have already failed, cleaning is only the first step — the covering needs attention too, and pressure washing sound tiles does more harm than good Read the full guide.
We check the extent of moss and the condition of the tiles underneath before touching the roof. For Peartree jobs we factor in the local access from the outset — peartree's victorian terraces share normanton's tight terraced access, with rear work often needing careful scaffold planning.
A fixed price for careful clearing and biocide treatment — never aggressive pressure washing.
Booked at a suitable dry window for treatment to work.
Moss is scraped and brushed off by hand and a biocide applied that continues to kill regrowth over the following weeks.
Gutters and valleys cleared of shed moss, and advice on keeping it from returning.
| Job | Typical duration |
|---|---|
| Moss clearing (semi) | half a day–1 day |
| Moss clearing + biocide | 1 day |
| Biocide treatment only | 2–4 hours |
| Clearing + gutter clear | 1 day |
| Large/detached roof | 1–2 days |
Biocide needs a dry spell to work — we time treatment for suitable weather. On Peartree's period stock these are realistic timeframes, not optimistic ones.
Moss clearing is done carefully from ladders, a tower, or roof ladders; we never walk sound tiles unnecessarily. Scaffold is specified for: large or steep roofs where safe roof access is needed - always itemised in your written quote, never a hidden extra, and we arrange it.
Peartree's Victorian terraces share Normanton's tight terraced access, with rear work often needing careful scaffold planning. Pavement scaffold and skip permits go through Derby City Council; allow a few working days on streets like Pear Tree Road, Portland Street where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Moss clearing (semi) | £250–£500 | Manual, no pressure wash |
| Clearing + biocide | £350–£700 | Continued kill |
| Biocide treatment only | £150–£350 | Per roof |
| Clearing + gutter clear | £350–£650 | Combined |
| Large/detached roof | £500–£1,000 | Per scope |
Worked example: Manual moss clearing and biocide on a north-facing semi in Allestree near the park — about £480.
No deposit on moss treatment — payment on completion. VAT included.
Covering DE23 and surrounding postcodes.
We guarantee the roof is cleared and treated properly; the biocide continues working for weeks, and we never pressure-wash, which strips the tile surface and shortens its life. Every Peartree job carries it, whether you are near Pear Tree Road or out toward Portland Street.
If covered work ever fails, you call us and we sort it, at no further cost.
Low-disruption external work — some moss debris cleared from below, gutters flushed, and nothing left behind. You do not need to stay home for external work - we just need power and access agreed in advance.
Biocide treatment needs a few dry days to take effect; Derby's damp Derwent-valley air and shaded northern slopes make moss a recurring issue we treat to slow, not just clear. Peartree's century-old slate roofs suffer nail sickness, and the exposed stacks take the brunt of Midlands storms.
Biocide-only treatment on a standard Pear Tree semi: £150–£300. Full treatment including mechanical clean: £300–£600. Free quotes on all Pear Tree moss treatment work.
Typically 4–7 years depending on aspect and tree cover. North-facing Pear Tree properties with significant tree cover closer to 4 years; open-aspect properties 6–7 years.
Yes — pressure washing strips the weathering layer from concrete tiles, making them more porous and accelerating future moss growth. We use biocide treatment and mechanical removal only.
October or November — after summer growth slows and before winter rainfall. The wet winter following treatment washes dead moss off the roof naturally. Spring is a reasonable second choice.
There is no permanent prevention for moss on concrete tile roofs. Zinc or lead ridge capping inhibits regrowth on adjacent tiles. Regular 5-year treatment cycles are the most cost-effective long-term approach.
Yes — thick moss responds well to combined biocide and mechanical removal. Very heavy growth may require a second treatment pass. We include a follow-up check at 6 months on request.
No call-out fee. Fixed price. 10-year guarantee on all work.
