Warm Roofs

This new roof extension on a roof in Brentwood, Essex, was relatively straightforward despite the prominent central skylight and the fact it adjoins the main roof. The polymer system's inherent flexibility means details and joins are no problem.

As the photo shows, the finished roof is jointless and seamless, and "perfect forming" around the central skylight. It was also fully mechanically cured within 72 hrs, fully waterproof and weatherproof within a few hours, and is guaranteed to last.

This flat roof on Spear Street in Manchester needed a warm roof installation (click to find out more about warm roofs, cold roofs and flat roofs, or use the nav link above). To ensure good heat efficency, the government set strict U-Values for many types of roof, with lower numbers being better. Using hte polymer system, we were able to achieve a fantastic 0.15 U-Value on this roof.

Take a look through the pictures above to see the finished jointless, seamless polymer roof.

What Now?

This roof in Tal-Y-Bont in Ceredigion (between Aberystwyth and Machynlleth) shows what can happen when previous roofers have not fitted a roof to proper standards in accordance with Building Regulations - in this case, serious condensation problems.

This flat roof in Waunfawr, Aberystwith in Ceredigion (West Wales) required warm roof insulation to comply with government U-values regarding (a measure of the rate of heat transfer across a surface). Roof "obstacles" and detailing are no problem at all for the polymer system but in this case were sparse, being limited primarily to chimney venting.

The abutting roof on this property on St Davids Road in Aberystwth needed full insulation to comply with governmental "U-Value" standards. "Warm roofs" differ from cold roofs in that they do not require ventilation and the insulation is placed above, rather than between the joists. They are required by law on certain roof types such as where people will live and/or work beneath or, as here, where an extension meets the main roof (see warm roof section for more on this).

This seaside property in Borth (Ynyslas) on the west coast of Cerdigion in Wales really put the polymer system through its paces, using the system's incredible versatility to achieve multiple ends that ultimately involved not just roofs but walls and windows.

The house now has a polymer lined balcony, converted from an existing roof area, a fully sealed and watertight Dorma window, and coated walls, protecting it from the worst of the Welsh weather and sea winds for many years to come.

This rubber clad plywood on this balcony flat roof in Flint, North Wales had failed, deteriorating in several places. This was the third time the roof had had to be replaced in the space of 12 years and the owner was now seeking alternatives. As the pictures show, the flat roof was over a hollow storage area which adjoined the house. A new substrate was required along with a waterproof covering.

QA Project reroofing the Llandinam Building, a laboratory on Aberystwyth University's Penglais Campus:

Multiple factors problematised the successful waterproofing of this laboratory refurbishment, including issues with keeping the building itself waterproof while the works progressed.

The laboratory roof has a series of higher levels draining into central chute outlets and discharging onto lower level roofs. These lower roofs have glazing along their entire lengths.

Troon, on the west coast of Scotland, is known not only for its golf course but also for its strong winds, which come from the Atlantic and from the north down the Firth of Clyde. This makes it an excellent spot for windsurfing and kitesurfing, but a challenging spot for roofs!

One new 14 apartment development on the main seafront road illustrates this well - the roof area wrapped around the complex, each area presenting its own requirements and each requiring reliable longterm protection from the corrosive salt-rich sea air and the worst weather the Atlantic will throw at it.

Knowing the polymer system's flexibility and our high standard of work, Aberystwyth University in West Wales asked us to solve a tricky skylight issue...

Flashings and kerb upstands tend to be manufactured to particular sizes, meaning that non-standard skylights made to special size requirements can often present a challenge.
