Imagine spending time and money renovating your home, only to find leaks and cracks in the roof after just a few years. Frustrating, right? Choosing roofing materials isn’t just about price—it’s about longevity and durability. Today, we compare popular roofing options to determine which truly stands the test of time.
The market offers a dizzying array of roofing materials, from budget-friendly choices that may need replacing sooner to premium options that promise durability. To help you make an informed decision, we’ve analyzed the pros and cons of the most common roofing materials.
Polycarbonate sheets are a popular choice due to their strength, durability, and light transmission. They are relatively easy to install and versatile, suitable for garden pergolas, carports, and more.
The lifespan of polycarbonate sheets depends on material quality, installation, and climate. High-quality sheets can last over 20 years. They come in various colors and thicknesses, with options like solid or multi-wall panels. Proper installation with aluminum locking systems can further extend their lifespan.
Lifespan: 20+ years
Acrylic sheets resemble polycarbonate but are cheaper. However, they have significant drawbacks: lower strength, shorter lifespan, and installation challenges. Acrylic is 17 times stronger than glass, while polycarbonate is 250 times stronger. Its lifespan is typically 5–10 years, and it’s prone to cracking during installation.
Lifespan: 5–10 years
Corrugated stormproof sheets are among the most durable transparent plastic roofing options. Made from high-strength resin, they are 200 times stronger than glass of the same thickness. UV protection prevents brittleness, ensuring clarity and longevity. With proper installation, these sheets can last over 20 years.
Lifespan: 20+ years
Corrugated PVC sheets are a budget-friendly alternative to stormproof sheets. While less durable, they are lightweight and suitable for small garden roofs or pergolas where high impact resistance isn’t required.
Lifespan: 5–10 years
Bitumen sheets are affordable and easy to install, making them a common choice for sheds or garages. However, their lifespan is limited—typically 10–15 years—depending on climate and maintenance.
Lifespan: 10–15 years
Corramet sheets, made from a specialized plastic composite resin, offer a durable, corrosion-proof alternative to bitumen or metal roofing. They can span up to 4 meters without overlaps, reducing the need for excessive support. Ideal for low-maintenance garden structures.
Lifespan: 20+ years
Metal sheets are durable and can last up to 30 years with maintenance, but they are prone to rust and corrosion, especially in humid or coastal areas. They are also among the most expensive options, with longer lead times.
Lifespan: 15 years (varies by type and rust resistance)
Made from cement, cellulose fibers, and water, fibre cement sheets are highly durable and impact-resistant, commonly used in agricultural settings. Their industrial appearance limits residential appeal, but they can last up to 40 years.
Lifespan: 40 years
For long-lasting performance, Corramet and stormproof corrugated sheets are the top choices. Both offer corrosion resistance and lifespans exceeding 20 years. For transparent roofing, stormproof sheets are unmatched, while Corramet is ideal for solid panels. Metal and fibre cement are also durable but come with higher costs or aesthetic limitations.
