The Silverstone Guarantee

You should never have to bear any risk when you’re choosing what to put on your roof. If you can’t rely on the roof over your head, what can you rely on?

That’s why, at SSQ, we guarantee our Silverstone roofs for 30 to 75 years – letting you sit back and enjoy a pristine slate for three-quarters of a century.

Testimonials

We specified SSQ First Domiz Blue-grey roofing slate for both technical and aesthetic reasons:its strength and quality gives the performance needed and its cold, hard, colour provides a dramatic foil to the rich warmth of the western red cedar walls.

Mark Webber, Architect, Nichols Brown Webber

Testimonials

Everyone liked Sarria: the client was delighted with its appearance and its consistency made it easy to cut and lay.

Gary Lambert, Complete Roofing Contractors

Testimonials

With the roofs being such a visible feature, the choice of roofing slate was a significant decision. We involved the roofing contractor at an early stage in the selection process and they recommended SSQ’s Del Carmen Blue-black slates. Although it’s not an indigenous slate, it is an excellent match for the originals and, having used Spanish slate on other projects, we know the quality is there.

Richard Thorpe, Ridge and Partners LLP

Testimonials

It was an absolute pleasure to meet you today, and I just wanted to take a moment to thank you for your time and a wonderfully informative CPD.

The whole team really enjoyed it, and you definitely conveyed your passion and knowledge of your products!

I would say I will keep SSQ in mind for future projects, but they always have been. However, I have definitely left with a need to utilise more slate in my design work!

Michael Clifton BSc ACIAT - Oakbridge Bespoke Homes Ltd

Testimonials

The choice of SSQ Del Carmen was made easier after confirmation that it had gained approval for use in the Welsh National Parks as an alternative to indigenous materials. We were also pleased with the level of technical, design and on-site support we received from SSQ.

The Hafod Renewal Office

Testimonials

The quality and strength were there, the colour was similar to indigenous Welsh slate and its ‘traditional’ look was in keeping with the surrounding community. In fact, as I had used it on my own Edwardian house, I knew it was a good slate!

Julian Bohling, OSP Architecture

Testimonials

SSQ Matacouta slate was chosen as the most sympathetic option. Its consistency and competitive price make it a clear winner over indigenous slates.

Historic Scotland

Testimonials

It is a very attractive development and we needed something equally attractive and of equally high quality for the roofing material. SSQ Del Carmen slate is top quality, and we liked the colour and texture. What’s more, it is very good value. I’d have no hesitation choosing it again.

Mr Keith Wills, Clancy's Building Manager

Testimonials

With so many ‘interested parties’ the local planners set their minds on a natural slate roof at a very early stage of the project and, from this starting point, we needed something that would satisfy a number of technical and aesthetic requirements – SSQ Domiz blue-grey, was the one chosen for use to compliment the local ‘Shere Green’ colour.

Ben Hunt, Total Project Integration

Testimonials

The choice of slates was made easier due to the quality of product you provide and the support of Gary Firth throughout the process – which I much appreciate. Gary is a good ambassador for your company.

Pat Murray, Senior Project Engineer, Alvance Group

Testimonials

We put forward Riverstone as a cost-effective, yet high quality alternative to Welsh Slate, and it was accepted on that basis. The refurbishment work has now been completed and both the owners and ourselves are very happy with the result.

Keith Hicks Architect at Pave Hall

Testimonials

SSQ Rocaber Blue-grey slate was actually chosen at the initial design-concept stage. A natural slate roof was in keeping with the traditional local architecture.
