Corrosion on metal sheets at step in roof(Emergency) - 02/08/2021
Quantity: 14 EA
Deficiency:Corrosion has been found on the metal under sheets and flashing at the step in the roof, some areas show an advance corrosion state, the rust is eating through the metal creating holes on the system. This is happening in 14 different areas across the roof due to build up of debris holding moisture under the turndown and in turn corroding out the flashing and metal sheets. The metal sheets are very weak and brittle in this location and requires major intervention work to make this roof safe and waterproof.
Corrective Action:Due to the location of the rust on the under sheets and complexity of carrying out any repair works to this area which occurs across the entire roof on both sides, we strongly propose a re-roof solution as the best approach as we can also design a better flashing detail to prevent this from occurring in the future.
We are happy to discuss some local temporary solutions to this area but due to the location and complexity will only help temporarily extend the serviceable life of the roof. Please note these will only be a temporary solution in order to try to stop the corrosion prosses and it will require regular maintenance.
