I've been seeing people using Aluminium as fascia board or as a decorative parapet. 🤣 This is just covering blockwork with no proper reinforced concrete coping. Roofers l working directly on it during installation.
⚠️ DANGERS & DRAWBACKS OF USING ALUMINIUM FOR PARAPET/FASCIA:
1. No Structural Strength, this thing cannot carry load—it is purely decorative, not structural.
During roof installation or future maintenance, if someone steps or leans on it, it can buckle or collapse, causing injury or fall 😭
2. No Protection Against Water Pe*******on
Parapets are meant to act as protective shields for block walls from rain.
Without reinforced concrete coping and proper screeding, water will seep into the blocks, leading to:
Damp walls
Mold growth
Premature cracks and degradation
I dey tell you truth oo
3. Easily Dismantled or Vandalized
Aluminium sheets are lightweight and can be easily stolen or removed.
In areas with theft risks, this is a real concern.
4. Thermal Expansion & Contraction
This thing can expands under heat and contracts when cool. This causes:
Buckling or warping of the fascia/parapet
Gaps opening up over time, allowing rainwater pe*******on
5. False Appearance of Concrete
Clients or potential buyers may assume it is a reinforced concrete parapet, which is misleading. You can't confuse someone like me.🤣
In reality, it offers no actual structural or weatherproofing value.
6. High Wind Risk
Strong wind can lift or tear off the aluminium parapet if not properly fixed with anchors.
This becomes a flying hazard, especially during storms.
✅ PROPER SOLUTION
If the goal is aesthetics and protection:
Use reinforced concrete parapet or coping beam.
Apply proper waterproof screeding and flashing.
Then you can still cover the front with decorative aluminium fascia for finishing.
