Who Are We?

Sterlingbuild is a fast growing, successful company based in Folkestone, Kent. We moved here as the growing success of the company meant we needed much bigger premises. Within 6 months of moving, we had grown so fast we had to build an office extension!

We sell "daylighting solutions"; that is, roof windows, skylights, sun tunnels, flat roof windows and domes, as well as flashings, blinds and other accessories. We're known for having a successful relationship with roof window manufacturers, including VELUX, FAKRO, RoofLITE, Lightway and Korniche.

The products we sell are primarily used in loft conversions, home extensions, self-builds and other renovation projects. Take a look at our Pinterest account for examples of how our products are used.

The Sterlingbuild brand is growing rapidly, and is regularly searched by our customers to find reasonably priced pitched and flat roof windows, rather than brand names. We're rather proud of that! Our logo and logotype are trademarked.

Our history

In 2006, was launched after Nick West saw the potential for selling VELUX windows online. He created the Sterlingbuild website with the aim of creating a different service for DIY enthusiasts:

“We want to give homeowners the convenience of a one-stop shop that offers a broad range of quality finishings for their home improvement projects.”

In 2008, Sterlingbuild Ltd was formed, based in Dover, and was joined in 2010 by former VELUX sales manager David Mayo as the sales and marketing director.

Unlike many other online retailers, we sell the entire product catalogue of our suppliers, the majority of which is available on our website. We aim to guarantee the best delivered prices to customers and do this with our popular Price Match Plus guarantee.


In 2009, the team created a new website, It was created to provide the cheapest lead roof flashing online for the UK roofing industry. Lead rolls were – and still are – sold based on weight. After the initial success of the website, Ubbink products were added to the site, which has rapidly grown to include many more roofing brands and supplies at low prices.

A trade counter was set up in 2010 where we sold roof windows and roofing supplies to local roofers, builders and DIY enthusiasts. A small warehouse stocking popular products meant the team could deliver roofing products to customers to Kent and London delivery addresses at lower prices.

Roofinglines has rapidly grown in size and revenue. We regularly work with roofing materials manufacturers, such as Cromar, to provide training days for employees and local roofers.

Roofing supplies shop

Following the company’s move to much larger premises, the Roofinglines shop was established to sell roofing materials, loft windows and uPVC windows to local businesses and homeowners. Customers are able to test products in the Concept Room – a mock-up of a loft with VELUX windows installed.

Present times

Following the rapid success of the Sterlingbuild and Roofinglines websites, the directors realised the need to hire more staff to support the number of orders and growth of the company.

With the help of the Regional Growth Fund, Sterlingbuild moved to larger freehold premises in Folkestone in July 2014. The strategically placed 1.1 acre site on the Park Farm Industrial Estate includes a large bulk warehouse, despatching warehouse, and larger offices, as well as the Roofinglines shop and customer parking.

Within 6 months, the team quadrupled in size, fulfilling the terms of the Local Growth Fund to take on new employees from the local area.
