SPECIALIST TRADE SERVICES

Installation support for real projects.

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

01 / TRADE SERVICE

Roof lantern installation

Lantern systems for suitable flat or low-pitched roof projects, coordinated with upstands and waterproofing details.

02 / TRADE SERVICE

Flat rooflights

Fixed or opening rooflights for prepared flat-roof openings, depending on product system.

03 / TRADE SERVICE

Pitched-roof windows

Roof windows and skylight installations where the roof build-up and manufacturer requirements are suitable.

Replacement roof glazing

Assess replacement of existing rooflight units, subject to compatibility, access and surrounding roof condition.

05 / TRADE SERVICE

Trade installation only

Fit contractor-supplied roof glazing where product suitability and divisions of responsibility are clear.

06 / TRADE SERVICE

Roof interface planning

Agree upstands, drainage, flashing, weathering, safe access and sequencing with the roofer.

WHY WORK WITH DF?

Built around trade priorities.

Specialist installation conversation

Discuss glazing details without pretending the roofer must be the window specialist too.

Clear waterproofing split

Identify exactly who completes membranes, flashings, roof covering and sealing interfaces.

Better sequencing

Arrange fitting after support and upstands are ready and before final adjacent finishing where appropriate.

Manufacturer-led details

Check specified roof pitch, fixings, structural support and system instructions before acceptance.

PRACTICAL PROJECT PLANNING

Roof glazing relies on the roof beneath it.

Roof lantern and rooflight projects need more coordination than ordinary replacement windows. We need the roof construction, opening sizes, upstand details, manufacturer instructions, safe access arrangements and a clear waterproofing responsibility matrix before offering an installation scope.

01

Send the details

Tell us the project address, intended systems and what needs installing.

02

Review the specification

Share drawings, unit schedules, manufacturer details and access requirements.

03

Agree scope & timing

Confirm supply, lifting, installation interfaces, finishing, programme and compliance responsibilities.

04

Fit & hand over

Carry out agreed work, check operation and discuss any outstanding items.

TRADE QUESTIONS

Frequently asked questions.

A few practical details to settle before appointing a glazing subcontractor.

Can DF fit a lantern that our roofing company supplies?

We can consider installation-only work for suitable systems when manufacturer instructions, component lists and the opening details are provided.

Who is responsible for waterproofing the roof?

The division between roof covering, upstand weathering and rooflight installation must be agreed explicitly with the roofing contractor before work starts.

Do you install pitched roof windows?

Suitable roof window enquiries are welcome, subject to the roof structure, covering type, supplier and access arrangements.

What should we send for a rooflight quote?

A roof plan, opening dimensions, pitch, upstand specification, product link or datasheet and project postcode.

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.
