📞 Call Now: 0122 528 7924Most Bath roof repairs trace back to a handful of failure points: a slipped slate, cracked mortar, or tired lead flashing letting water past. The tell-tale signs usually show inside before the roof looks obviously wrong.
When it is not the answer: If more than about a third of the covering has failed and slates lift by hand across the whole slope, repairing tile-by-tile is money wasted. Read the full guide.
Velux window installation in Bath carries considerations not present in most UK locations. The majority of Bath's Victorian and Georgian housing has pitched roofs in Welsh slate or clay plain tile, and the integration of a roof window into these surfaces requires careful attention to flashing specification, tile or slate cutting, and, for conservation area properties, planning and material compliance.
For Victorian properties in Oldfield Park, Bear Flat, Widcombe and Bathwick, the Velux EDL lead-clad flashing kit is the most conservation-sympathetic installation option. This kit uses lead-finished flashings that integrate naturally with the surrounding Welsh slate and is the system most commonly accepted by Bath planning officers for permitted development Velux installations. For listed buildings and more sensitive locations, we advise on planning implications and alternative systems before any work is committed.
For concrete interlocking tile roofs in Twerton, Foxhill, Whiteway, Keynsham, and the wider BA2 and BS31 catchment, standard Velux EDW or EDP flashing kits are used, sized to the specific tile profile. We cut tiles cleanly, seal all joints, and test for water tightness before leaving the site. Standard centre-pivot installations on a concrete tile roof are typically completed in 3 to 5 hours.
Failed flashing kits on existing Velux windows are a common repair call across Bath. The original flashing kits on Velux windows installed in the 1990s and early 2000s are now reaching the end of their service life, and water ingress around the window perimeter is the first sign of failure. We replace flashing kits on all Velux models without removing the window unit, and include inspection of the surrounding tile or slate bed to confirm no secondary water paths.
Single Velux GGL (centre-pivot, fitted): £450–£800
Velux with EDL lead flashing (period property): £600–£1,100
Flashing kit replacement (existing Velux): £200–£450
Broken glass replacement: £150–£350

| Job | Typical duration |
|---|---|
| Slipped or cracked slate refix | 1–2 hours |
| Lead flashing repair | Half a day |
| Ridge or verge re-bed (per section) | Half to full day |
| Rear valley rebuild | 2–3 days |
| Multiple-fault repair visit | 1 day |
Wet or high-wind days pause work at height — we build weather margin into every Bath booking and never leave a roof open.
Most Bath repairs run from roof ladders or a tower; scaffold is specified only where the job needs safe standing time at height. Scaffold is specified for: chimney-side repairs, full valley rebuilds, and anything beyond a day at height - always itemised in your written quote, never a hidden extra, and we arrange it.
Bath's Georgian and Victorian terraces mean tight pavements, controlled parking, and rear-access scaffold on many streets. Pavement scaffold and skip permits go through Bath & North East Somerset Council; allow a few working days on streets like Milsom Street, Broad Street, Margaret's Buildings where space is tight.

Workmanship on the repaired section is covered for 10 years in writing; any replacement slates or tiles carry their manufacturer warranties on top.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
A repair is usually a day of ladder or tower work with a small amount of debris — we sheet below the work area and clear everything before we leave. You do not need to stay home for external work - we just need power and access agreed in advance.
Repairs run year-round; if rain stops work mid-job we fit temporary weatherproofing the same day so no more water gets in. Bath's valley setting holds humidity, so north-facing slopes dry slowly and moss builds up through autumn.
“Two Velux windows installed on our Victorian semi in Oldfield Park as part of a loft conversion. Bath Roofing matched the EDL lead flashing to the surrounding Welsh slate perfectly. The conservation officer raised no objections to the installation.”
“Velux on our 1970s semi in Twerton — straightforward installation into the concrete tile, done in half a day. Good price, no mess.”
“Failed flashing kit on a 10-year-old Velux on our Bear Flat property was letting in water around the perimeter. Bath Roofing replaced the flashing kit, re-dressed the surrounding slates, and confirmed no water ingress on the first rainfall. Quick and effective.”

For conservation area properties, the dimensions must balance light output against visual impact on the roof plane. We can advise on the appropriate size as part of any loft conversion or window installation consultation.
