What do commercial & industrial rooflights in Machynlleth involve?
Our commercial & industrial rooflights service in Machynlleth covers rooflights for warehouses, schools, offices and retail units. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. In Machynlleth, as anywhere, commercial & industrial rooflights are the usual choice for industrial roofs with tired or fragile rooflight sheets.
We work across Powys, including Machynlleth, and in neighbouring towns such as Dolgellau and Aberystwyth. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Machynlleth
- GRP or polycarbonate in-plane rooflight sheets
- Smoke and natural ventilation vents
- Modular glass rooflights
- Continuous barrel-vault rooflights
- Polycarbonate domes
- Fall-protection planning included
- Smoke-vent options where needed
What to check first
- Non-fragility classification should be confirmed for new products
- Fire performance of rooflight materials matters near boundaries
Building control and safety duties in Machynlleth
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Are old rooflights a safety risk?
Older plastic rooflight sheets can become brittle. Anyone working on the roof must treat them as fragile unless proven otherwise.
Do you supply O&M information?
Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
Can you replace old warehouse rooflight sheets?
Yes. We match the roof profile, replace discoloured or damaged sheets and plan safe access while the building stays in use.
Do you fit commercial & industrial rooflights in Machynlleth?
Yes. We survey and fit commercial & industrial rooflights in Machynlleth and across Powys. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Machynlleth?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
