Skylight replacement for Grangemouth: the essentials
We handle skylight replacement across the Forth Valley, including Grangemouth. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Tenements and flats are common in Scottish towns and cities, where rooflights over stairwells and top-floor flats need the owners' and factor's agreement. Skylight replacement suits older extensions due a modern rooflight.
From Grangemouth to Falkirk, Bo'ness and Alloa, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Roof window replacement in pitched roofs
- Dome to flat glass upgrade
- Like-for-like size replacement
- Upstand rebuild and insulation
- Fixed to electric opening
- Usually done in a day
- Better thermal performance
Before you order: points to check
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Planning and building rules for Grangemouth
In Scotland most rooflights on houses fall under Class 2B permitted development; in a conservation area, or on a listed building, consent is needed. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 3.3 W/m²K. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
