Re-felting your flat roof can be a complicated and time consuming process if you don't know what you are doing. However, it can be a DIY job if you have the right information and a little insider knowledge.
Using roofing felt
Most people only consider using roofing felt on flat roof extensions, but as technology moves apace, the amount of people using this material on standards roofs is increasing exponentially. Where once roofing felt was deemed to be an inferior roofing material this is most definitely no longer the case.
In the past a roof fitted with roofing felt usually had a life span in the region of 10 years before the felt would need to be replaced. However, the new torch-on roofing felts currently available mean the time between re-felting has increased. And now most torch-on roofing felts come with a much longer guarantee, especially when they are used with a torch-on roofing felt underlay.
All a competent installer needs are the right tools to complete the job successfully. However, working on any roof can be extremely dangerous, so if you are in any doubt you should contact a roofing specialist.
