This flat roof extension had been on for about 25 years so the built up felt system had lasted well.
Since undertaking full training in the GRP glass re-inforced plastic roofing materials I suggested the 20 year GRP Scott Bader system for this roof. The felt and boards were completely removed, an upgrade in insulation to the latest standards and then a new timber substrate and the grp system applied on top.
There were some timber repairs and remedial work to be done and the removal of the old gas vent which came through the roof. With the current spate of wet weather the newly installed roof covering has more than shown it is the material for the future and does it’s job very well indeed.
The garage flat roof here has come to the end of its life and I was asked to replace it with a new 3 layer felt roof system. Click the images to enlarge for more detail.
This is the garage completed with a torch on mineral felt. I used a high-grade felt with minerals as a top coat. A first layer is laid loosely to allow for movement, a second layer
torched on with a burner going opposite way to first layer then a last third layer with edge details torched on to finish.
As you can see the finished roof in a mineral top coat surface. Compared to the original lime stone chippings on the roof shown below, the roof I supplied and installed it’s a lot neater looking and a more durable finish.
A flat roof replaced with three layers of built up felt with a torch on mineral top coat to finish. The original felt never went up under the neighbours ridge tiles on the adjoining wall so I removed the ridge tiles carefully and put my felt up and over the wall, then bedded the ridge tiles back on with sand & cement.
Carrying out the work using this method gave a more weatherproof finish to the new felt roof covering and with the re-fitting of the ridge tiles it gave the fabrics an upgrade for both properties.
