How much does roof coating cost — and how to preserve it
Lots of New Zealanders find it easy to ignore roof maintenance on commercial buildings, and this leads to deterioration of the paint coating and in time damage inside the structure supporting the roof. What building owners soon discover is that neglecting the roof becomes problematic, to a point where the whole roof could need to be replaced versus just a recoat.

Cleaning the roof
This is the first and most crucial step. Using a pressure washer, remove all the moss and any debris that may be on the roof. Do this when required.
Inspect the roof
Inspect the roof to see if there are any cracks or broken tiles that need to be fixed. If there are, make sure the cracks are repaired before moving on. If you cannot fix the roof yourself, get professionals to do it for you. Never take chances with your safety.
Applying the roof coating
Once everything is checked, cleaned and prepared, ensure the roof is 100% dry. Moisture and condensation can impact on coating adhesion, so check the weather forecast. Put on all necessary safety wear and confirm all areas are safe before you begin work.
Benefits of maintaining the roof coating regularly
