Flat Roofs

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.

This wraparound roof in Talybont in Ceredigion, West Wales, was badly leaking and in desperate need of repair and refurbishment. Water was pooling everywhere, the existing surface was ripped, lifting and leaking, and moss had formed in clumps over much of the surface.

Despite this, the underlying roof was still sound and able to be reused!

This row of eight garages in Troon, South Ayrshire (less than 40 miles west of Glasgow), was in need of a roof, quickly.

The area, as can be seen from the photograph, was relatively large, around 160m2, and required a full flat roof system. Because of continuity of work, the contractor needed a quick turnaround and dry storage needed to be preserved.

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. 

The roof of the Ceredigion Training Centre at Llanbadarn on the outskirts of Aberystwyth was in dire need of proper insulation. The existing roof did not conform to government U-values and the cold roof was costing the training centre money in heating. 

We worked with the existing mastic asphalt roof, saving time, money and resources. The entire area was cleaned, with increased ply fascias fitted in preparation for the roof to receive the tapered insulation - a thickly insulated power deck designed for foot traffic.

Two balconies demonstrate the outstanding waterproofing properties of the polymer balcony system. The system is guaranteed 100% waterproof over all areas of application. Drainage channels are of course then installed so that water can drain away!

This flat roof in Barry in the Vale of Glamorgan was in need of refurbishment as its existing single ply membrane was leaking. With the high winds and rain of Autumn and Winter 2015, this was causing problems for the owners, who needed to find a lasting solution quickly.

We over-coated the roof with a jointless, seamless liquid membrane system which would wholly prevent any further leakage or water ingress, saving electro testing, as well as ensuring the roof would stay leak-free for at least another 20 years.

This building at Stratford-upon-Avon in Warwickshire required a warm roof with a u value of .13 in order to compensate for an unusually large surface area of glass below (from patio doors & other glass elavations).

The system insulation was 220mm thick, fully adhered, and did not need an extra layer of ply decking to sandwich the insulation, as the insulation we used is specially manufactured to be walked on for limited access without damage.

This onetime-garage flat roof in Comins Coch a mile outside Aberystwyth in West Wales needed to conform to strict U value standards as it was being remodelled as a family kitchen and would be attached to the main property, thus making it a warm roof as well as a flat roof.
