Roof Coating & Restoration in Derby

No, and we will tell you plainly if that is what your roof actually needs. Coating and restoration is for a roof that is still structurally sound — the covering, fixings and underlay are basically doing their job but look tired, chalky or mossy — not for a covering that has genuinely failed. Where nail fatigue is widespread or the underlay has perished across the roof, the honest answer is roof replacement and re-roofing, and selling a coating over that would only delay the real fix while making it look temporarily better.

It comes down to the free on-roof survey, not a guess from the pavement. We check the tiles or slates and their fixings, the state of the underlay where it is visible, the ridge and hip mortar, and any render or roofline around the covering, and we look for signs of the widespread failure that would rule restoration out. A roof with isolated faults — a few loose ridges, some eroded pointing, a handful of cracked tiles, general dirt and discolouration — is usually a strong candidate; a roof with fixings failing across the board is not, and we say so in the written quote.

Yes, if the wrong product goes on the wrong build-up, which is exactly why the coating choice follows a survey rather than a default. A non-breathable, film-forming coating applied where the roof space cannot otherwise ventilate can trap moisture inside instead of keeping it out, creating a condensation risk that BS 5250 — the British Standard covering moisture and condensation control in buildings — exists to manage. Using a breathable coating system where the construction calls for it, and not coating at all where the build-up is unsuitable, is how that risk is avoided rather than created.

Roof cleaning removes moss, algae and grime from the surface of a sound covering and is a job in itself — see roof cleaning and moss removal for that on its own. Restoration includes a clean as one step but goes further, re-pointing eroded ridge and hip mortar, re-bedding ridges that have worked loose, and replacing broken or slipped tiles found during the work, before any protective coating is applied. If all a roof needs is the dirt and moss removed, a clean is the right and cheaper job; if the ridges are loose or tiles are cracked underneath the grime, that is restoration.

It covers the render above the eaves and the roofline boards — fascias and soffits — beneath the gutter, which age alongside the covering on Derby's solid-wall Victorian and Edwardian terraces. Work typically means cleaning and repairing hairline cracking or chalking render, and cleaning, repairing or refinishing fascia and soffit boards that have flaked or streaked with algae, restoring the whole roof line rather than leaving newly restored tiles above tired brickwork and boards. It is scoped alongside the roof restoration itself, using the same access, rather than as a separate visit.

There is no fixed rate, because the price is driven by the roof's size, its condition, and how much repair — re-pointing, re-bedding, tile replacement — the survey finds before any coating goes on. A small, already-tidy roof needing mainly a clean and protective coat costs a good deal less than a larger roof or terrace run with several ridges to re-bed and tiles to replace first. We give a fixed written quote after the free survey, itemising the repair scope and the coating separately, so you see exactly what you are paying for and why.

A straightforward restoration on an average pitched roof — clean, re-point, re-bed a ridge or two, coat — is typically completed within one to two days on site, weather allowing, since coating work stops in rain. A larger roof, a full terrace run, or one needing several tiles replaced and more extensive re-pointing before coating takes longer. We set a realistic programme in the written quote once the survey has scoped the actual repair work, rather than quoting a generic figure before seeing the roof.

Yes — any broken, cracked or slipped tile found during the survey or the clean-down is replaced to match before the roof is coated, because coating over a broken tile only hides the gap it leaves rather than fixing it. Matching tiles are sourced to suit the existing covering, whether that is a concrete interlocking tile on a Littleover or Mickleover semi or a clay plain tile on older Derby stock. Restoration is scoped to leave the whole covering sound, not just visually refreshed.

Drier stretches in spring through early autumn suit coating work best, because the covering needs to be dry for cleaning, re-pointing and the coating itself to cure properly, and Derby's roughly 779 mm of rain a year is spread fairly evenly through the seasons rather than concentrated in one obvious window. Winter restoration is possible between spells of wet or freezing weather but is more likely to be delayed, since coating and mortar work both stop in rain or frost. We build realistic weather contingency into the programme whatever time of year the survey happens.

The repair element — re-pointing, re-bedding and any replaced tiles — carries a workmanship guarantee like any other roof repair we coordinate, and any coating product applied follows the manufacturer's own stated terms, which are set out at quote stage rather than promised verbally. We do not attach an invented lifespan figure to a coating, because how long a finish performs depends on the roof's construction, ventilation and exposure, which is exactly why the survey and the correct breathable system matter more than the coating alone. That way the guarantee you are given is one we can stand behind in writing, rather than a headline number that means little once the weather gets to work.
