Fixing Roof Water Leaks
Insurances agencies state that 80% of building insurance claims come from water leaks and water damage.
Costly and extensive damage to houses & buildings are often the end result of roof water leaks.
Paul Evans, Managing Director Findlay-Evans Waterproofing (F.E.W) and Vice President of the Australian Institute of Waterproofing (AIW) says " water can track a significant distance from the point of roof entry which makes fixing roof water leaks all the more challenging".
"I've seen devastating consequences of not fixing leaking roofs - once water is in , the whole problem escalates, " said Mr Evans.
Surface Preparation Prior to Waterproofing Application
As with all waterproofing membranes, the surface must be dry and free of anything that could adversely affect adhesion.
- You should be sure to remove all loose, scaling, peeling, blistering, chipping, cracking, chalking or gravel, dust, dirt, sand, soot, grease, oil, uncured tar, wax, soap film, animal fats or petroleum-based residue, coal tar, chlorine, salts, efflorescence, or any other chemically reactive substance (solvents) that may affect adhesion.
- Wire brush or if needed high-pressure water blast should be used to thoroughly clean all surfaces prior to application if any of the above conditions exist.
- Surface should be free of mould, mildew, dirt & as dry as possible.
- Mildew and similar growths can be killed with 1 part household bleach to 2 parts water, followed by a thorough rinse with clean water.
- All surfaces must then be allowed to THOROUGHLY DRY before proceeding with application.
