What we do
What Is Skylight Installation?
A skylight, or roof window, is a glazed unit fitted into the roof structure to bring natural daylight and often ventilation into the room below. Velux is the best-known brand, though there are various roof-window manufacturers and styles.

What a Skylight Does
A roof window brings natural daylight, and often ventilation, into the room below — usable light without the cost of an extension.
Why It's Important
Loft conversions and top-floor rooms are often the darkest in a house, with only small dormer or gable windows if any. A skylight adds usable natural light without the cost of an extension.
Types of Skylights
Fixed skylights let in light but don’t open, and tend to be the most leak-resistant. Opening or ventilating skylights, manual or electric, add fresh air alongside light. Roof lanterns and flat-roof skylights suit extensions, while tubular sun tunnels bring daylight into rooms where a full skylight isn’t practical.

Signs You Need Roof Repair in Bristol
If any of these sound familiar, a new or repaired roof window is usually a straightforward fix.
Dark, Airless Loft Rooms
If a converted loft or top-floor room relies entirely on artificial light during the day, a skylight is often the simplest fix.
Condensation Between Panes
Misting or condensation trapped inside the glazing itself, rather than on the inside surface, usually means the seal has failed and the unit needs replacing.
Water Staining Around the Frame
Discolouration or damp patches around an existing skylight frame point to a flashing or seal failure rather than a problem with the glass — often a targeted roof repair.
Difficulty Opening or Closing
Stiff or jammed opening mechanisms on older ventilating skylights are a common repair rather than a sign you need a full replacement.
Root causes
What Causes Skylight Problems
Nearly every skylight problem traces back to flashing or seals — rarely the glass itself.
Flashing Failure
The vast majority of skylight leaks come down to flashing that’s aged, was poorly fitted, or was damaged during other roof work — not the skylight unit itself.
Age and Seal Breakdown
Double-glazed units eventually lose their seal, letting condensation build up between the panes — a sign the unit needs replacing rather than repairing.
Poor Original Installation
A skylight fitted without a proper flashing kit, or into a roof not correctly prepared for it, is far more likely to leak. One fitted correctly during a full roof installation rarely gives trouble.

The cost of waiting
Why Skylight Problems Shouldn't Be Ignored
Water Damage to Ceilings and Timbers
A slow skylight leak can damage plasterboard, insulation and roof timbers for months before it becomes obvious inside the room.
Energy Loss
A failed seal doesn’t just look bad — it lets heat escape, pushing up heating costs in the room below.
Escalating Repair Costs
A flashing repair caught early is inexpensive. Left long enough to damage the surrounding roof structure, the job becomes considerably more involved.
How we work
Our Skylight Installation Process
Five steps, no guesswork — the diagnosis drives the repair, not the other way round.
01
Consultation and Roof Assessment
We look at the roof pitch, structure and the room below to recommend the right skylight type and size for the space.
02
Preparing the Opening
Where fitting a new skylight, we cut the opening in the roof structure and prepare the surrounding rafters to manufacturer specification.
03
Fitting and Flashing
The skylight unit is fitted and sealed with a proper flashing kit — the single most important step in preventing future leaks.
04
Interior Finishing
Internal plastering, lining and, where relevant, blinds are completed to finish the job neatly from inside the room.

Skylight-Related Components
Flashing Kits
A correctly matched flashing kit for the roof covering — tile, slate or flat roof — is essential for a watertight installation, and worth checking as part of a roof maintenance plan.
Loft Conversion Structure
Skylights are often installed as part of a wider loft conversion, so timing the roof-window work alongside structural changes makes sense.
Blinds and Ventilation Accessories
Many skylights can be fitted with integrated blinds or trickle ventilation, worth considering at installation stage rather than adding later.

How Much Does Skylight Installation Cost in Bristol?

Factors Affecting Cost
Skylight type and size, roof pitch, and ease of access all affect the final price. A complex flat-roof or steep-roof job needing scaffolding costs more than a simple pitched-roof fit.
Typical Price Ranges
Average skylight installation in Bristol runs around £550 to £1,000, with a straightforward replacement of an existing unit typically costing somewhat less.
Planning Permission
Most skylight installations don’t need planning permission, but conservation areas may have different rules, and all work must comply with building regulations.
The honest comparison
Fixed vs Opening Skylights
When Fixed Skylights Make Sense
Fixed units suit spaces that need light but not ventilation, and their simpler construction means fewer potential leak points over time.
When Opening Skylights Are Better
Bedrooms, bathrooms and kitchens generally benefit from an opening skylight for ventilation, particularly where there’s no other window in the room.
Cost comparison: fixed skylights are generally the more affordable option, while electric or solar-powered opening models cost more — both for the unit and installation — but add convenience where reaching a manual handle isn’t practical.
Done properly
Benefits of Professional Skylight Installation
Natural Light
A well-placed skylight brings usable daylight into rooms that would otherwise depend on artificial lighting during the day.
Improved Ventilation
Opening skylights help clear moisture and stale air from loft rooms and bathrooms, reducing condensation problems.
Energy Efficiency
Modern double- or triple-glazed skylights are well insulated, adding light without the heat loss older single-glazed units used to cause.
Increased Property Value
A bright, well-converted loft with proper natural light is a genuine selling point for Bristol’s period and terraced housing stock.

Frequently Asked Questions
Skylight installation in Bristol typically costs around £550 to £1,000, depending on the type of window, roof pitch and access. Replacing an existing skylight is usually somewhat cheaper than a first-time installation.
Generally not for a standard domestic skylight, though conservation areas may have additional restrictions. All installations still need to meet building regulations regardless.
The great majority of skylight leaks come from failed or poorly fitted flashing rather than the glass unit itself. If a well-installed skylight starts leaking years later, ageing flashing is usually the first thing to check.
Yes, in most cases. Many roof windows can be fitted with external work limited to the immediate opening and flashing, without full scaffolding or re-roofing.
A standard single skylight installation usually takes about a day. Multiple skylights or more complex roof structures can take two to three days.
