For many homeowners, the task of replacing a flat roof on a garage is likely if the property is more than a few years old. Flat roofs are renown for leaking in and if not addressed problems and damage escalate requiring even more remedial work to be carried out. The options open to people needing to replace a flat roof used to be limited and felt roofing was really the only choice but in recent years as a wider variety of roofing materials have become available the options are more varied.
Re-felting is still an option and is seen as a good, relatively cheap, solution to the problem of a leaking roof. The downside to using this material is that it is affected by the elements and so does deteriorate over time meaning that it will probably need replacing in about ten years.
A roofing material that many people are turning to is rubber roofing. Sheets of a rubberised material are glued to the stripped roof of the garage and edged appropriately to ensure it is watertight. Although more expensive the life of this type of roof is upwards of twenty-five years so for many people it will only need to be done once. Unlike felt it is not affected by the elements so should not deteriorate in the same way.
