How can I cover a balcony roof?

A balcony roof can be covered using several different options, depending on the level of protection needed:

• Polycarbonate or acrylic panels – Lightweight and affordable
• Fixed glass roofs – Allows natural light while offering weather protection
• Solid flat roof systems (felt or GRP) – Provides full rain protection and durability

An experienced installer should be able to recommend a suitable, long-lasting solution that’s right for your balcony, and budget.
