Roof glazing installed with care.
Installation services for builders, extension companies and roofing trades requiring roof lanterns, flat rooflights or pitched roof windows for suitable Hertfordshire and North London projects.
Discuss supply responsibility, programme, site readiness, product specifications and access before a project is confirmed.

Installation support for real projects.
The right service depends on your system, site and agreed responsibilities. Here are the installation packages we can discuss.

WHY WORK WITH DF?
Built around trade priorities.
Product-specific preparation
Check pitch, upstand or kerb size and fitting instructions before finalising the job.
Roof trade coordination
Agree sequencing, temporary waterproofing and who completes final roof coverings.
Safe lifting and access
Glazing size and site arrangement inform the installation plan.
Handover and checks
Agree opening operation, seals and the scope of final testing.
PRACTICAL PROJECT PLANNING
A rooflight is part of a wider roof system.
Roof glazing interacts with insulation, vapour control, roof covering, drainage, support and internal finishing. We need clarity over the responsibilities for each interface so an otherwise well-fitted unit is not blamed for unrelated water entry.

Review the specification

TRADE QUESTIONS
Frequently asked questions.
A few practical details to settle before appointing a glazing subcontractor.
What is the difference between a roof lantern and a flat rooflight?
A roof lantern typically rises above the roof on glazed sides; a flat rooflight is a flatter glazed unit. Both need an appropriate roof build-up and compatible upstand or kerb.
Do you fit contractor-supplied roof windows?
Suitable products can be assessed with manufacturer instructions, flashing details and roof construction information.
Can these be used on new extensions?
Potentially, subject to the project design, structural support, planning and applicable Building Regulations.
Who completes surrounding roof membranes?
The roofing contractor and installer must agree this interface before installation.
What areas do you cover?
DF Installations is Hatfield based and considers projects across Hertfordshire, parts of North London and nearby Bedfordshire, subject to location, capacity and scope.
