What do commercial & industrial rooflights in Dagenham involve?
For Dagenham homes and buildings we offer commercial & industrial rooflights: rooflights for warehouses, schools, offices and retail units. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of commercial & industrial rooflights for industrial roofs with tired or fragile rooflight sheets.
Jobs in Dagenham are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Regulations for commercial & industrial rooflights in Dagenham
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Can you replace old warehouse rooflight sheets?

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.

Yes — product data, manufacturer warranties and maintenance notes are handed over at completion.
