What is polycarbonate roofing and why is it used in Kenya?
Polycarbonate roofing is a lightweight, high-impact plastic roofing material used for transparent and semi-transparent roofing applications. It is widely used in Kenya due to its durability, UV resistance, and ability to allow natural light into buildings.
It is commonly used in car shades, skylights, greenhouses, walkways, and modern commercial roofing structures.
Polycarbonate roofing is preferred because it:
- Reduces energy costs through natural lighting
- Withstands heavy impact and harsh weather
- Performs well under strong UV exposure
- Requires less structural support than glass
Is polycarbonate roofing strong and durable?
Yes. Polycarbonate roofing is extremely strong and can withstand high impact forces, making it one of the most durable transparent roofing materials available in Kenya.
It is significantly stronger than glass and does not shatter easily, making it ideal for high-risk or high-traffic construction environments.
Durability depends on:
- UV coating quality
- Sheet thickness (commonly 6mm–10mm)
- Installation quality
- Environmental exposure
Does polycarbonate roofing work in hot and sunny climates like Kenya?
Yes. Polycarbonate roofing performs well in hot and sunny climates due to its UV-resistant coating and heat-dispersing properties.
It reduces heat penetration while still allowing natural light, making it suitable for both residential and commercial roofing.
Regional performance factors:
- Nairobi: stable UV exposure
- Mombasa: high humidity and salt air require premium UV protection
- Kisumu: high rainfall and heat cycles
- Eldoret: cooler temperatures and wind load considerations
What thickness of polycarbonate roofing is best?
The best thickness depends on the application, but most roofing projects in Kenya use 6mm to 10mm sheets for a balance of strength and flexibility.
Thicker sheets provide better impact resistance and insulation but require stronger structural support.
Typical usage:
- 6mm: car shades, pergolas, greenhouses
- 8mm: light commercial roofing, walkways
- 10mm+: industrial skylights and heavy-duty roofing
Structural support systems often include:
- Zed Purlins
- Square Hollow Section (SHS)
- Rectangular Hollow Section (RHS)
- Circular Hollow Section (CHS)
Does polycarbonate roofing turn yellow over time?
Low-quality polycarbonate sheets may turn yellow over time due to UV exposure, but high-quality UV-protected sheets maintain clarity for many years.
Proper material selection and installation significantly reduce discoloration in Kenyan conditions.
Key factors:
- UV protection level
- Sun exposure intensity
- Cleaning and maintenance
- Material grade
Is polycarbonate roofing waterproof?
Yes. Polycarbonate roofing is fully waterproof when properly installed with correct overlaps, sealing, and structural spacing.
Leakage issues usually come from poor installation rather than material failure.
To ensure waterproofing:
- Maintain correct roof slope
- Use proper fixing accessories
- Avoid overtightening screws
- Ensure correct sheet overlap
Drainage systems often include:
- PVC Gutters
- Pipe systems from the pipes catalog
Can polycarbonate roofing be used for commercial buildings?
Yes. Polycarbonate roofing is widely used in commercial and industrial buildings across Kenya for skylights, canopies, and covered walkways.
It is valued for durability, natural lighting efficiency, and low maintenance.
Common uses:
- Shopping mall skylights
- Petrol station canopies
- Factory roofing systems
- School walkways
- Airport structures

What is the difference between solid and hollow polycarbonate sheets?
Solid polycarbonate sheets are clear and glass-like, while hollow sheets contain air channels that improve insulation and reduce weight.
Choice depends on project needs.
Comparison:
| Feature | Solid | Hollow |
|---|---|---|
| Transparency | High | Medium |
| Weight | Heavier | Lighter |
| Insulation | Moderate | High |
| Cost | Higher | Lower |

How do you maintain polycarbonate roofing?
Polycarbonate roofing should be cleaned using mild soap and water to maintain clarity and prevent surface damage.
Avoid abrasive materials or harsh chemicals.
Maintenance steps:
- Clean every 3–6 months
- Remove dust and debris
- Avoid scratching surfaces
- Inspect fasteners regularly
Is polycarbonate roofing expensive in Kenya?
Polycarbonate roofing is moderately priced but offers long-term value due to durability, low maintenance, and reduced structural requirements.
Initial cost is higher than basic roofing materials but lifecycle cost is lower.
Pricing factors:
- Thickness
- UV protection level
- Sheet type
- Installation complexity
