Due to massive improvements over the last couple of decades traditional bitumen felt roofing is once again a very viable product to use. Primarily for use on flat roofs, this is the alternative to the more modern EPDM rubber and GRP roofs that are now being fitted.
This traditional bitumen felt roofing system looks great on older houses or on roofs where people like to stick with what they know. Not only does this material look great when fitted correctly it also works amazingly and we still have roofs that are 20 years old plus still functioning and looking good.
Polyester felt is the base material used to make bitumen roof shingles and bitumen roll roofing.
Used for decades as waterproof coverings in residential and commercial roofs, these bitumen felt compositional membranes incorporate two layers.
The first underside polymer membrane is used as a solid background, nowadays reinforced with glass fibers, which are much stronger than the old types used and then mineral granules are added to make up the self-protective top layer, with a final bituminous mixture encapsulating them both.
Bitumen felt roofing felt is manufactured in roll format. Rolls of base felt are pulled on rollers through large tanks of bitumen mixes until they are saturated with the tar-like bitumen mixture, producing rolls of water-resistant but breathable material.
what we do to make your new bitumen felt roof?
When doing this type of job we completely strip the existing felt roof and take it back to the existing timber base.
If the base is damp or rotten, we remove and replace it with a thick water resistant ply.
As mentioned above we then apply a 2mm torch on layer of fibreglass reinforced bitumen felt and heat seal all the seams to make it completely watertight.
Next comes the protective top layer which is a 4mm mineral coated bitumen felt system which is dressed up any walls or edges upwards to keep the water contained on the main roof area.
Finally we nail on and dress up protective bitumen felt flashings to all edges to make a third seal against water ingress.
Due to having worked with this product for so long and being so knowledgable with it we can guarantee this type of roof for 10 years, and it is highly likely you will get double that time out of your roof due to the massive improvements in the material that has come about over the last 20 years.
