Recently a customer of Irish Roofers asked us the question "how do you install Flat Roofing" so I decided to write a series of articles on roofing from flat roofs to slate and tiled roofs.
First of all for flat roofing we require a good solid base made of timber joists. The size of these joists will depend on the span of the roof.
Next we install 8x4 plywood sheeting which is screwed to the joists, ensuring that there is no give where the plywood sheets meet.
We then torch on two layers of roofing felt using a blow torch, ensuring that it's set to just the right heat so as not to heat the felt too much.
