The right service depends on your system, site and agreed responsibilities. Here are the installation packages we can discuss.
Lantern systems for suitable flat or low-pitched roof projects, coordinated with upstands and waterproofing details.
Fixed or opening rooflights for prepared flat-roof openings, depending on product system.
Roof windows and skylight installations where the roof build-up and manufacturer requirements are suitable.
Assess replacement of existing rooflight units, subject to compatibility, access and surrounding roof condition.
Fit contractor-supplied roof glazing where product suitability and divisions of responsibility are clear.
Agree upstands, drainage, flashing, weathering, safe access and sequencing with the roofer.
Discuss glazing details without pretending the roofer must be the window specialist too.

Arrange fitting after support and upstands are ready and before final adjacent finishing where appropriate.
Check specified roof pitch, fixings, structural support and system instructions before acceptance.
