Case studies

Brander lane

04 Apr 2020

The client had a recent survey on the property before she brought it and knowing all the underlying problems the poorly installed failing felt roof was causing after she brought the property. The client contacted the flat roofing company addressing the problems she had occurred we all agreed the best option to stop any problems in the future and assurance of longevity and performance.

Existing felt roof is failing miserably with sections of blistering water under the felt system that had previously been installed and felt. I find it hard to understand how someone has installed this for a customer.

We done a complete strip off taking it down to the existing joists and insulation these being in pretty good condition considering. New 18mm marine plywood was installed to existing joists and a new opening for skylight created. Evalon VSK was fully adhered to new ply substrate. Old ridge tiles wee taken off and this allowed us to re-ply and membrane the parapet wall. Once completed the existing ridges were installed.

Leydene Road

04 Apr 2020

Flat roof area upgrades before + after at 6 Leydene Road.Our client decided to upgrade all the flat roof areas to warm roofs. The old skylight had water coming through it as well as multiple areas of pooling water becoming a concern. We completed a core sample test to show how much insulation each roof needed to meet the required U-values. The top bedroom roof we installed a tapered insulation scheme and drop down to eradicate any pooling issues. Eva-therm insulation has been bonded to the existing felt roofs with Alwitra Evalon VSK single ply membrane fully adhered to the insulation. The kitchen extension old skylight frame was removed, and a new timber frame was built correctly, and skylight lantern installed once membrane completed. Matching trims all round as well as a new sky lantern supplied by the flat roofing company.

River way

04 Apr 2020

River way project was a refurbishment of a domestic property with a new side extension in the Christchurch area. We gave the client several different options and different systems that suited the client and more importantly being the most cost effective for them. Once all details were confirmed the client agreed they would be insulating the extension from inside. The Roof was completed with 18mm OSB plywood and a 300mm lay board joining the pitch to the flat. A 50 mm drip batten was installed on the outside perimeter to have ample distance for when fascia and gutter is installed. Evalon VSK single ply membrane was fully adhered on to the ply substrate finished with a 100mm water check and 50mm drip detail.

Salisbury Racecourse

04 Apr 2020

We had the pleasure of installing a warm roof on the new paddock bar at Salisbury racecourse. The ply substrate roof was built with a 1:40 fall with box gutter to meet all standard requirements. A polythene BBA certified loose laid vapor control layer firstly installed for condensation purposes and Evatherm 150mm insulation mechanically fixed to stop any potential wind uplift happening. Evalon self-adhered single ply membrane was laid and all laps homogeneously welded. After Drainage calculations were taken 3 x 110mm vertical outlets installed to take the volume of water coming off the cladded roof and newly installed membrane roof.

Flat roof refurb - Canford cliffs

24 Oct 2019

*Flat roof refurb*
We recently completed this small project in Poole. The flat roof was leaking and caused a power cut. In 1 day we created a slight pitch using timber furrings and plywood. After insulating the sides we used a single ply membrane to waterproof the area. Just the tiles left to be all new!
This membrane allows us to overlay the existing roof meaning there are no penetrations or openings. Perfect for this time of year!
20 year warranty and full insurances.
