Why Skylights Leak (and How We Fix It)

Most leaks are not from the glass—they come from installation details:

• incorrect or aged flashing kits
• poor upstand detailing on low-pitch roofs
• missing insulation around reveals causing condensation confusion
• failed previous patching with short-life sealants

We repair the full interface, not just the visible symptom.

Our Installation Process

1. Suitability check — roof pitch, orientation, and structural spacing reviewed.
2. Product selection — fixed, vented, or solar options based on room needs.
3. Precision fit and flashing — installed to manufacturer and weatherproof standards.
4. Water test and quality check — full seal verification before handover.

Best Rooms for Skylights

• attic conversions and loft bedrooms
• kitchens and open-plan living spaces
• hallways and landings with limited wall windows
• bathrooms (vented units help reduce humidity)

Common Upgrade Options

• solar venting for bathrooms and kitchens
• integrated blinds for glare control
• upgraded glazing for energy performance
• larger formats for open-plan spaces

Skylight Installation Standards and Long-Term Performance

Skylights add major value when they are integrated properly into the roof system. Most recurring skylight leaks are caused by flashing, perimeter detailing, or insulation continuity issues rather than the glazing unit itself. Our process prioritizes weatherproof integration so your skylight performs well in Irish rain and wind over the long term.

Before any installation or repair, we assess roof pitch, covering type, rafter spacing, and internal finishing constraints. This ensures unit selection, flashing kits, and opening preparation are aligned with the roof system instead of being forced into an unsuitable configuration. We also check ventilation and condensation risk, which are often overlooked in fast-fit installations.

For replacements, we inspect the existing opening and surrounding detailing to decide whether a direct swap is appropriate or whether perimeter correction is needed. For new installs, we plan structural support, weatherproof sequencing, and internal finish transitions in one scope so homeowners avoid hidden extras later in the project.

What is included in a professional skylight scope

• roof suitability check and product-fit confirmation
• opening preparation with structural and weatherproof considerations
• compatible flashing and perimeter detailing
• insulation and condensation-risk control around the opening
• internal finishing coordination guidance
• final water-shedding and seal checks
• handover care and maintenance guidance

Common skylight issues we correct

• persistent leaks around the skylight curb or flashing line
• draft complaints from poor perimeter insulation
• condensation concerns linked to ventilation imbalance
• degraded seals and aged legacy units
• repeat patch repairs that never addressed core detailing

New installation vs replacement: budgeting clearly

Replacement projects are usually faster and lower cost where the opening and surrounding details are sound. New installations may involve extra structural and finishing work depending on roof build-up and internal layout. We provide clear line-by-line scope so homeowners can compare options properly.

Planning and compliance considerations

Many skylight projects can proceed as exempt development, but this can vary by property type and location context. We recommend checking local authority guidance for protected structures or conservation-related constraints. Where needed, we can sequence technical inputs so the project remains compliant and practical.

How to compare skylight quotations

When reviewing quotes, make sure each proposal clearly states:

1. skylight model/specification and glazing type
2. flashing kit type and compatibility with roof covering
3. inclusion of internal making-good scope
4. access requirements and safety setup
5. cleanup/disposal responsibilities
6. workmanship and product warranty details

Ongoing maintenance for Irish homes

A simple annual check of flashings, drainage paths, and interior moisture signs can prevent expensive failures. In high-exposure locations, post-storm visual checks are recommended. If your skylight has leaked previously, a full perimeter detail review is usually better value than repeat sealant-only patching.

If you are planning a loft, attic, or daylight upgrade, we can provide staged options that balance performance, aesthetics, and budget while keeping weather resilience as the top priority.

Quick checklist before approving a skylight quote

• confirm flashing kit compatibility with your roof covering
• verify what internal finishing is included or excluded
• ask for condensation and ventilation guidance in writing
• check access assumptions and setup requirements
• confirm final handover checks for water-shedding performance

These points reduce surprises and help ensure your skylight performs long-term in Irish weather.

FAQs: Skylights Ireland

How much does a skylight installation cost in Ireland?

Typical installations range from €1,200 to €3,200, depending on roof type and unit specification.

Are Velux windows worth it?

Quality skylights improve natural light and can improve comfort and ventilation, making them a strong long-term upgrade.

Can you fix a leaking skylight without replacing it?

Often yes—if the unit is sound, flashing and perimeter detailing can be repaired.

Do skylights increase heat loss?

Modern double or triple-glazed units are efficient when installed correctly with proper insulation detailing.

Can skylights be added to older roofs?

Yes, in many cases. We assess structural spacing and roof condition first.
