Another cold wet Monday morning on the roof and another roof leak due to poor workmanship. Why do so many flat roofs leak? It's a question we get asked all the time, and unfortunately, the answer often comes down to one thing: poor installation.
In this article, we'll explore the hidden costs of poor workmanship and why investing in quality installation from the start can save you thousands in the long run.
The True Cost of a "Cheap" Roof
When homeowners and businesses are quoted for a new flat roof, it can be tempting to go with the cheapest option. After all, a roof is a roof, right? Unfortunately, this couldn't be further from the truth.
"The bitterness of poor quality remains long after the sweetness of low price is forgotten." - This old saying couldn't be more true when it comes to flat roofing.
What Makes a "Cheap" Roof Expensive?
- Early failure: Poorly installed roofs often fail within 5-10 years, rather than the 20-35+ years you should expect
- Repeated repairs: Constant patching and repairs add up quickly
- Interior damage: Leaks can cause significant damage to ceilings, walls, and contents
- Mould and damp: Water ingress can lead to health hazards and expensive remediation
- Complete replacement: Often, a poorly installed roof needs to be completely redone
Common Signs of Poor Workmanship
Over the years, we've seen the same issues time and time again when we're called out to fix other people's work:
1. Poor Detailing
The details are where most flat roofs fail. Upstands, edges, corners, and penetrations (like skylights or vents) need to be properly detailed. Rushed or inexperienced installers often cut corners here.
2. Inadequate Preparation
Failing to properly prepare the substrate before installation is a common shortcut. This can lead to poor adhesion and early failure of the membrane.
3. Incorrect Materials
Using the wrong materials for the application, or inferior quality products, is a recipe for disaster. We've seen roofs where the wrong adhesive was used, or where incompatible materials were combined.
4. Poor Drainage
Flat roofs need proper falls (slope) to ensure water drains away. Puddling water is a major cause of premature roof failure.
Warning Signs to Look For
If you notice standing water on your roof after rain, water stains on ceilings, bubbling or blistering on the roof surface, or damp patches on walls - these are all signs that your roof may have been poorly installed.
