In this article, we explore 7 of the best roofing options for house construction in Sri Lanka, highlighting their benefits, common uses, and maintenance tips to help you make the right choice for your dream home.
So, without further ado, let’s start reading…
1. Asbestos Cement Sheets
Asbestos cement sheets are roofing materials made by combining cement with asbestos fibers. This combination results in strong, lightweight sheets that have been widely used in residential construction due to their durability and affordability.
Benefits
Asbestos cement sheets offer several advantages for house construction:
- Strength: The addition of asbestos fibers reinforces the cement, making the sheets sturdy and long-lasting.
- Affordability: Compared to other roofing materials like tiles or metal sheets, asbestos cement sheets are cost-effective.
- Longevity: With proper installation, these sheets can last for many years without significant deterioration.
Concerns Associated With Asbestos Cement Sheets
While asbestos cement sheets are strong and durable, there are serious health considerations:
- Health Risks: Asbestos fibers can be hazardous when inhaled, potentially causing lung-related illnesses over time.
- Safer Alternatives: Due to these risks, many homeowners now prefer fiber cement sheets, which provide similar benefits without the health hazards.
Common Uses
These sheets are commonly used in:
- Economical residential roofing for houses on a budget.
- Outbuildings, such as storage sheds and garages.
- Temporary shelters or structures requiring affordable roofing.
Maintenance Tips
To ensure safety and extend the life of asbestos cement sheets:
- Regularly inspect for cracks, chips, or damage.
- Avoid drilling, cutting, or breaking sheets to prevent releasing fibers.
- Consider replacing old sheets with fiber cement alternatives for a safer long-term solution.
2. Aluminum Roofing Sheets
Aluminum roofing sheets are lightweight metal sheets commonly used in house construction. Made from high-quality aluminum, these sheets provide a durable and practical roofing solution that suits a variety of residential structures. Their lightweight nature makes them easy to handle and install, reducing construction time and labor costs.
Benefits
Aluminum roofing sheets offer several advantages for homeowners:
- Corrosion Resistance: Aluminum naturally resists rust, making it ideal for Sri Lanka’s humid and coastal regions.
- Easy Installation: The lightweight design allows for quicker and simpler installation compared to heavier roofing materials.
- Long-Lasting: With proper care, aluminum roofs can last for decades while maintaining their appearance and structural integrity.
Maintenance Tips
Even though aluminum sheets are low maintenance, a few simple practices help maintain their durability:
- Clean the sheets periodically to remove dust, dirt, and debris.

Maintenance Tips
Proper maintenance ensures long-term performance:

5. Zinc-Aluminum Coated Steel Sheets
Zinc-aluminum coated steel sheets are metal roofing materials made by applying a protective layer of zinc and aluminum over steel. This coating enhances the sheet’s durability and resistance to corrosion, making it suitable for Sri Lanka’s humid and coastal environments.
Benefits
These sheets provide several advantages for residential construction:
- Strong: Steel core offers excellent structural strength.
- Rust-Resistant: The zinc-aluminum coating protects against corrosion, even in salty or humid conditions.

Maintenance Tips
Proper maintenance ensures longevity:
- Inspect the roof annually for scratches, dents, or loose fasteners.
- Touch up any damaged coating to prevent rust and corrosion.
- Clean off accumulated debris to maintain the protective layer.
6. Tile Roofs
Tile roofs are made from clay or concrete tiles and have been a popular choice in Sri Lanka for both traditional and modern homes. These tiles are known for their durability, aesthetic appeal, and ability to provide natural insulation against heat.
Benefits
Tile roofs offer several advantages:
- Attractive Appearance: Tiles give homes a classic, elegant look that enhances overall architecture.
- Heat Insulation: Clay and concrete tiles help maintain cooler indoor temperatures in hot climates.

To keep tile roofs in optimal condition:
- Replace broken or cracked tiles promptly to prevent leaks.
- Remove moss, leaves, and other debris that may accumulate on the roof.
- Check for loose tiles, especially after storms or strong winds, and secure them as needed.
7. Fiber Cement Roofing Sheets
Fiber cement roofing sheets are made from a combination of cement and reinforcing fibers, without the use of asbestos. This makes them a safer alternative to traditional asbestos cement sheets while maintaining durability and strength.
Benefits
Fiber cement sheets offer several advantages for residential construction:
- Strong and Durable: More resistant to breakage compared to wood or plastic sheets.
- Fire-Resistant: Provides added safety for homes, reducing the risk of fire damage.

FAQs
How long do different types of roofs last in Sri Lanka's climate?
Clay tiles can last 30 to 50 years with maintenance. Additionally, treated teak wood roofs last 25+ years if properly maintained. On the otherhand, metal roofs last varies based on coating and maintenance but can suffer faster corrosion near coasts.
What are the maintenance tips for roofs in Sri Lanka?
Regular maintenance includes cleaning gutters twice a year, checking and fixing loose or broken tiles after storms, sealing cracks promptly, trimming nearby tree branches, and inspecting flashing around vents to prevent leaks and damage.
Are clay tiles or metal roofs better for Sri Lankan homes?
Clay tiles are generally better for keeping homes cooler and resisting termites. They also blend well with tropical and colonial architectural styles. Metal roofs are more prone to corrosion, especially in coastal areas, but can be cheaper and quicker to install.
How to pick the right roofing company in Sri Lanka?
Choose companies with at least 10 years of experience in local roofing, licenses and insurance, good customer references, and knowledge of local weather challenges. Avoid companies with unrealistically low quotes, no proof of previous work, or lack of proper permits.
What are the common problems faced by roofs in Sri Lanka?
Common issues include leaks, mold growth, termite damage, rusting of metal roofs, and damage caused by strong monsoon winds and heavy rains.
How do coastal areas affect roofing material selection in Sri Lanka?
Coastal salt air accelerates rust on metal roofing and can degrade concrete and wood faster. Roofs near the coast require more resistant materials and coatings to handle salt corrosion and stronger weather impacts.
