Get a quote →A rooflight is a roofing job before it is a window job. Most rooflight leaks are flashing kit failures or wrong-pitch installations, not faults in the window itself. Across Yarm the pattern is fairly consistent: Georgian High Street properties, Victorian villas and modern executive estates.
When it is not the answer: If a rooflight is sound and only the seals have perished, replacing seals costs a fraction of a new unit. Whole-unit replacement is worth it when the frame has gone or the glazing has failed.
Yarm's housing stock is predominantly Georgian townhouses on the High Street and adjacent streets with clay plain tile and Welsh slate; Victorian semis on the residential fringe; modern detached on the outskirts toward Eaglescliffe. Knowing the specific roof types and their failure patterns is what separates a knowledgeable local roofer from a national firm that sends whoever's nearest.
River Tees on three sides creates higher humidity than inland towns, accelerating moss growth and mortar decay. Conservation area status applies to much of the town centre, restricting material choices on period properties. This directly affects how quickly specific problems develop and which repair approaches last longest in local conditions.
Lead flashing failure on Georgian and Victorian town centre properties; moss accumulation from river humidity on north-facing slopes; clay plain tile slippage on older properties; conservation area material constraints. We attend these jobs regularly across Yarm and carry the most common materials on the vehicle.
The roof pitch and the covering type determine which flashing kit is correct — getting this wrong is the single most common cause of rooflight leaks. On Yarm stock we allow extra time at this stage.
Unit size, glazing spec and the matching flashing kit named, with any structural work to form the opening priced separately.
Scaffold or tower to the working elevation with the roof protected below.
Rafters trimmed and structurally supported where a new opening is being formed, to building regulations.
Window set to correct plane, manufacturer flashing kit installed to the covering type, underlay dressed and sealed.
Reveal made good where agreed, unit operation checked, guarantee and manufacturer documentation handed over. For Yarm customers the guarantee document follows within 24 hours of sign-off.
One Yarm-specific note on scheduling: Yarm High Street is a conservation area with cobbled frontages, wynds too narrow for a wagon and heavy footfall — scaffold there is a licensed,… That gets confirmed before we give you a date, not after.
| Job | Typical duration |
|---|---|
| Like-for-like unit replacement | Half a day |
| New rooflight into existing roof | 1–2 days |
| Multiple units same elevation | 2–3 days |
| Flashing kit renewal only | 3–4 hours |
| Dormer window repairs | 2–4 days |
The roof is open while a unit is swapped, so we do not start a rooflight in unsettled weather. It is a same-day watertight job or it is not started.
Timings hold for typical Yarm stock. Tees loop position brings river fog and damp still air that keeps north-facing roofs green.
Rooflight work needs a working platform — tower on a bungalow, scaffold on anything higher. Scaffold is specified for: any rooflight above single storey, all new openings, and multiple-unit installations - always itemised in your written quote, never a hidden extra, and we arrange it.
Yarm High Street is a conservation area with cobbled frontages, wynds too narrow for a wagon and heavy footfall — scaffold there is a licensed, carefully programmed job through Stockton-on-Tees Borough Council. Pavement scaffold and skip permits go through Stockton-on-Tees Borough Council; allow a few working days on streets like High Street, Atlas Wynd, Silver Street where space is tight.
| Job | Typical range | Notes |
|---|---|---|
| Like-for-like unit replacement | £650–£1,200 | Including new flashing kit |

Worked example: Two rooflights replaced on a loft conversion in Hummersknott — like-for-like units, new manufacturer flashing kits matched to the plain tile covering, reveals made good — £1,950 including scaffold to the rear elevation.
Units are ordered to your specification once you accept the quote; a materials payment is taken at that point on bespoke sizes only, and never on stock units. Balance on completion.
All Yarm quotes itemise scaffold and waste separately so you can compare like for like.
Workmanship guaranteed for 10 years. Velux and equivalent units carry their own manufacturer warranties — typically 10 years on the unit and 20 on the glazing seal — which we register for you.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
On Yarm properties we note the covering type and fixing specification on the guarantee document itself, which matters on Georgian High Street properties, Victorian villas and modern executive estates.
A day or two with the roof open above one room, so that room wants clearing. Some dust from cutting, contained with sheeting. You do not need to stay home for external work - we just need power and access agreed in advance. For Yarm properties we confirm parking arrangements with you in advance.
Rooflights go in year-round but never into rain, because the covering is open during the swap. We book against the forecast. Tees loop position brings river fog and damp still air that keeps north-facing roofs green.

New Velux window installations in Yarm are generally permitted development — no planning permission required — provided the window sits flush with the roof slope and doesn't project more than 150mm. The main exceptions are listed buildings and conservation area properties, both of which exist in Yarm. Georgian townhouses on the high street and adjacent streets with clay plain tile and Welsh slate in Yarm — if your property is period construction we'll confirm any planning constraints at survey before materials are ordered.
The most common cause of Velux window leaks in Yarm is failed flashing rather than a fault with the window unit itself. Velux flashings are tile-profile specific — the wrong flashing kit for the tile type, or a degraded kit after 15–20 years, allows water to track around the frame and into the reveal below. Yarm's higher annual rainfall compared to southern England means flashings that might last 20 years in a drier climate show deterioration in 12–15 years. We replace flashing kits as the first step for any leaking Velux before recommending full unit replacement.
Yarm has a significant stock of older properties — Georgian townhouses on the High Street and adjacent streets with clay plain tile and Welsh slate, Victorian semis on the residential fringe, modern detached on the outskirts toward Eaglescliffe — where Velux installation requires matching the existing tile profile exactly. Velux manufacture flashing kits for most common UK tile profiles including Welsh slate, clay plain tile, and the standard concrete interlocking profiles used across the area's post-war housing stock. Where an unusual or discontinued tile profile is involved, we confirm the correct flashing specification before ordering to ensure a weathertight installation from day one.
In most cases no. Roof lights that sit flush with the roof slope and don't project more than 150mm are permitted development on most residential properties. Exceptions are listed buildings and conservation area properties — we'll flag this at survey.
The most common cause is failed flashing rather than a fault with the window unit itself. Velux flashings are tile-profile specific — the wrong kit or a degraded kit allows water to track around the frame. We can usually replace just the flashing kit, which is significantly cheaper than replacing the window.
A single window installation typically takes half a day to a full day including making good the tile work. Multiple windows take longer. We'll give a realistic estimate in your quote.
