A cost effective alternative to zinc, Catnic Urban steel standing seam roof and cladding met the desired aesthetics – with the quick fit system offering a fast and problem-free installation.

Hilary and Robert Garner wanted to open up their existing kitchen with a build that used full height glazing to flood the area with light and give them an unobstructed view of their garden. In response, architect Tim Hannon, from Brooks Architects in Leiston, designed a contemporary extension that provides a stunning focal point, reconnecting the inside to out.

“After we were convinced that Catnic Urban could achieve our desired aesthetic, our next concern was that the roofing and cladding could be exactly matched to the window frames and that the colour would stand the test of time. Again, we were assured of the system’s colour matching and stability credentials by everyone working on the project and we’re overjoyed with the result. Catnic Urban has really given the project the wow factor.”

The vaulted roof was designed to bring drama to the space, with a ridge that was purposely higher than the roof of the main house, so visitors are instantly given a glimpse of the striking design as soon as they approach the house. An overhang provides a covered outside eating area and works to reduce solar gain, with the sleek lines of the standing seam continued down the side of the extension, which is wrapped in matching cladding. Typical of the area, the design also includes a lean-to roof on an area that houses the utility room and cloakroom.

“I’ve worked with Catnic Urban on a number of projects and particularly like the fact that it is fully recyclable at end of life. The ease of installation also instils confidence that there will be no problems at fitting stage and the technical support offered by the Urban team is also excellent, with a good level of technical detail provided on abutments and ventilation, so that all the work is neatly finished.”

Catnic Urban steel standing seam roofing and cladding in Anthracite Colorcoat HPS200 Ultra was used across the project, recommended by project contractor Kerslake Construction Ltd, as a cost effective alternative to the zinc roof initially specified, when cost became a concern. “If a customer wants the look of zinc without the price tag, I recommend Catnic Urban”, said Jon, “and in most cases as soon as people look into the product they switch, as it looks great, achieving really smooth, clean lines that flow beautifully.”

Catnic Urban’s recommended contractor Steel Roof Installers UK was commissioned by Kerslake Construction to install the roof, as they have worked together on similar projects in the past. After attending a training course back in 2010, owners Chris Bates and Andy Morris were soon turned onto the benefits of building with Catnic Urban and now exclusively work on Urban projects.

“We came from a traditional tile and slate background and have found the move to only installing Catnic Urban immensely beneficial to our business. Being able to provide such a close aesthetic match to zinc at a significantly lower price appeals to all customers, no matter what their budget is. The ease of installation is also a big plus point for us, the quick fit system is exactly that, with invisible fixings developed specifically to offer fast, simple, on-site installation.”
