Detailed Service Guide

Skylights and roof windows are a transformative addition to any property, flooding dark attics, extensions, and stairwells with natural daylight and vastly improving ventilation. However, introducing an aperture into a solid roof creates a significant vulnerability. If not installed with absolute, uncompromising precision, a skylight will rapidly become a source of severe, persistent leaks. We provide expert installation and specialized repair services to ensure your roof windows perform flawlessly.

Our installation process for new skylights is meticulous and structurally sound. We begin by carefully removing the existing slates or tiles and cutting through the roof deck, often necessitating the precise modification of timber rafters to frame the new opening. The critical phase involves the integration of the window frame with the roof using proprietary, weatherproof flashing kits. These kits must be perfectly matched to the specific profile of your roof covering—whether flat tile, slate, or deeply profiled concrete—to guarantee a watertight seal.

Beyond new installations, we routinely repair failing skylights. Often, homeowners assume a leaking skylight needs total replacement, but the issue frequently lies with a degraded exterior flashing kit, a buildup of moss blocking the drainage channels around the frame, or a blown double-glazing unit. Our diagnostic approach identifies the exact fault, allowing us to clear blockages, replace perished seals, or install new glazing panes, restoring the integrity of the window at a fraction of the cost of a full replacement.

Warning Signs & When to Act

• Dripping from the Frame: Water dripping from the wooden or plastic interior frame of the skylight during or immediately after rainfall.
• Condensation Between Panes: A misty, foggy appearance inside the glass unit itself, indicating the hermetic seal has blown.
• Draughts and Whistling: Noticeable cold air entering around the closed window, suggesting the rubber weather seals have perished.
• Rotting Timber Surrounds: Dark, soft, or flaking wood on the interior frame, pointing to long-term, slow water ingress.

Scope of Work

Cutting roof openings, modifying rafters, installing Velux windows with appropriate flashing kits, replacing blown glazing units, and re-sealing old windows.

Our Process

1. Measuring and preparing the roof aperture from the inside.
2. Removing tiles and cutting the external felt.
3. Securing the window frame and fitting the weatherproof flashing kit.
4. Making good the interior plasterboard surrounds.

Inspection & Quality Checks

• Confirmation that the specific flashing kit perfectly matches the existing roof covering material and pitch.
• Thorough insulation and sealing of the gap between the window frame and the roof structure to prevent cold bridging.
• Smooth, bind-free operation of the hinges and locking mechanisms post-installation.
• Water testing the exterior perimeter of the installed unit to verify the absolute integrity of the flashings.

Project Preparation

Installing or repairing a skylight involves work both on the roof and inside the room below. Please clear the floor space directly beneath the window location, cover immovable furniture with dust sheets, and remove any valuable items, as the process generates unavoidable dust and debris.

Aftercare & Maintenance

To maintain your skylights, occasionally wipe down the exterior flashing channels to ensure leaves and moss do not obstruct the flow of rainwater around the window. Keep the interior timber frames clean and re-varnish them every few years if required to protect against ambient room moisture.

Quotation Checklist

• Ensure the exact brand, size, and glazing specification of the proposed skylight is clearly detailed.
• Verify that the appropriate flashing kit for your specific roof type is included in the price.
• Check if the quotation covers the internal 'making good' (plastering or trimming) around the new aperture.
• Confirm the specifics of the manufacturer's warranty on the glazing unit and the guarantee on the installation work.

FAQs

Can you fit a skylight into my existing roof?

Yes, we can retrospectively fit skylights into almost any pitched or flat roof without needing to rebuild the entire structure.

Why is my Velux window leaking?

Usually, the flashing kit around the window has failed, or leaves and moss have blocked the water channels around the frame.

Do I need planning permission for a skylight?

Typically, skylights fall under permitted development, provided they don't protrude too far from the roof slope, but we can advise on your specific situation.

Can you replace just the glass if it's misty?

Yes, if the timber or uPVC frame is sound, we can often replace just the blown glazing unit to clear the condensation.

Are skylights suitable for flat roofs?

Yes, we install specifically designed flat roof skylights and light tubes, complete with appropriate kerbs and flat roof membranes.
