Many roof refurbishment projects don't fail because of the waterproofing system.
They fail because the wrong decisions were made long before installation began.
Here are five of the most common reasons
01Inadequate Roof Assessment
Without a proper inspection, hidden issues such as moisture, substrate deterioration or structural movement can easily be overlooked.
02Choosing a Product Instead of a System
A waterproofing membrane alone cannot compensate for poor detailing, inadequate drainage or incompatible components.
The entire roof build-up must work together.
03Ignoring Existing Roof Conditions
Every existing roof tells a story.
Previous repairs, trapped moisture, ageing materials and structural movement all influence the refurbishment strategy.
04Poor Detailing
Many failures occur at
- Upstands
- Rooflights
- Penetrations
- Outlets
- Expansion joints
These areas require the greatest attention—not the large open roof areas.
05Lowest Price Becomes the Main Specification
A refurbishment should deliver value over the expected service life of the roof.
Selecting a system based solely on initial cost can often lead to higher maintenance costs and earlier replacement.
Successful roof refurbishment starts with understanding the building—not simply selecting a waterproofing product.
Inspect. Assess. Specify. Perform.
Because the right specification is built long before the first bucket is opened.
The right specification is built long before installation starts.
