Flat Roof Flashbanding Repair and Cleaning Needed in Cowes
There are about 12m of flashbanding needed on a single-storey flat roof of around 10m². The roof is very dirty, so it will need pressure washing and cleaning before repairs can be carried out.
What Is Flashbanding and Why Is It Needed?
Flashbanding is a self-adhesive, weatherproof tape used to seal joints and prevent leaks on flat roofs. Over time, weather exposure can cause existing flashbanding to deteriorate, leading to water ingress. Proper cleaning and application of new flashbanding help extend the life of an asphalt roof and improve its waterproofing.
Steps to Repair the Flat Roof with Flashbanding
The process involves:
- Pressure Washing: The roof surface is thoroughly cleaned to remove dirt, moss, and debris.
- Inspection: Any cracks, holes, or weak areas in the asphalt are identified.
- Preparing the Surface: Once dry, the surface is primed to ensure the new flashbanding adheres properly.
- Applying Flashbanding: A 12m length of self-adhesive flashband is carefully applied over joints and problem areas.
- Sealing and Finishing: The flashband is pressed firmly into place and sealed with a protective coating if required.
