Support Services

We offer advice and technical assistance on the application and specification of all rooflights and accessories. Full technical support is available, including site surveys, condition reports and budget costings, technical specification writing, NBS specifications, design and fully detailed quotations. You can also use the Whitesales NBS+ Creator.

A comprehensive library of product information and rooflight CAD drawings is available in our downloads area along with NBS specifications. And for projects where we have undertaken a rooflight site survey, we also offer a CAD roof plan drawing service. 


NBS Plus

Whitesales subscribe to the NBS Plus library of product clauses offered in NBS specification format. For a step by step overview of our specification support framework, download our Total Specification Support Brochure.

For continuous and bespoke products, especially the glass range, we can offer advice and design input. Talk to our design team on 01483 271371 to discuss any rooflight requirements that are a little out of the ordinary.


With depots strategically located in England and Scotland, our service driven team is readily available, from your initial enquiry through to aftersales support. Project and larger consignments are delivered on Whitesales’ own transport.


All our rooflights can be installed to a builders curb (timber, concrete, metal etc.) or our proprietary PVC or GRP Em-Curb, suitable for use with most flat roof systems including single-ply, felt, hot-melt, asphalt and liquid-applied membranes. Check with your waterproofing membrane manufacturer for specific compatibility guidance.

Where asphalt is specified, we recommend the use of PVC upstands with pre-fixed sheathing felt and expanded metal lathe. This must be specified if required. 

For installation guidance go to the relevant product page in the product area where you can find Installation Instructions.


All Whitesales rooflights, when installed on Em-Curbs or Em-Collars and in accordance with manufacturer’s instructions, are guaranteed against the effects of defective design, materials or construction for a period of 10 years from date of supply by Whitesales. Furthermore, the glazing element of all Whitesales  rooflights is guaranteed against discolouration for 10 years subject to certain conditions. A 20-year ‘special projects’ guarantee is also available. Further details available on request.
