Roofing felt deteriorates over the years because of exposure to sunlight and other elements. The membrane becomes porous with age and needs servicing. Sometimes a simple patch repair is all that is needed, or if the damage is extensive it may be necessary to replace the entire roof.
There are many roofing service companies which are able to give competitive roofing quotes. These estimates are usually free and a good company will back up their work with a guarantee and insurance. These roofing service professionals can do quick, clean and reliable roof replacements and repairs.
Bitumen roof membranes have improved over the years and now a high quality torch on roofing felt can last up to twenty years. There are also many DIY products available which can save the homeowner a lot of money. A torch on roofing felt is easier to apply than the old pour and roll method. The new bituminous reinforced membranes may look similar to the old felt roof; however, the materials used in their production have improved dramatically. This has made the roofing felt easier to apply as well as more durable.
Purpose made roofing gas torches should be used for applying torch on roofing felt. Two types of torches are needed, one with a short stem for detail work and the other with a long stem and high output burner for the main work. Timber surfaces can not be torched directly and require a torch receivable surface to be nailed on before the application of the rood felt. A roll bar should be available for the application of the membrane and a trowel for angle work. Full protective clothing should be worn and a bucket of cold water readily available to treat any burns. The membrane needs to be cut and laid so the side and ends are overlapping. A side lap should be a minimum of 75 mm and end laps should be a minimum of 100 mm. A good bead of bitumen should be formed at all laps to insure proper waterproofing. The roofing should be rolled forward as the film and bitumen melt; this is best achieved by applying the flame at the low point where the roll meets the underlay.
The company which supplies the torch on roofing felt should have a help line. These professionals can give advice on how to apply the membrane and also give any instructions about safety measures which should be taken to reduce the risk of injury or fires. Time should be taken to study and prepare before applying the new membrane.
