Can you repair a balcony roof?

Yes – in many cases, a balcony roof can be repaired rather than replaced. Repairs are often suitable if:

• The structure underneath is sound
• Damage is limited to the roof covering
• Leaks are coming from joints, seals, or surface cracks

That said, if the roof has widespread rot, sagging, or long-term water damage, replacement may be recommended instead.

How do you stop a balcony roof from leaking?

The right fix to stop a balcony roof from leaking depends on where the water is getting in. Common leak causes include:

• Failed waterproof membranes
• Cracked felt, fibreglass, or rubber roofing
• Poor drainage or blocked outlets
• Worn seals around walls or doors

Repairs usually involve resealing joints, patching damaged areas, or replacing sections of the waterproof layer to restore protection.

What is the best material to repair a balcony roof?

Common balcony roof repair materials include:

• Felt roofing: Affordable and easy to patch
• GRP (fibreglass): Long-lasting with seamless repairs
• EPDM rubber: Flexible and resistant to cracking
• Liquid waterproof coatings: Ideal for flat balcony roofs

Tip: Always aim to match repair materials to the existing roof if possible. This helps create a watertight finish and looks better.

Do you need permission to repair a balcony roof?

In most cases, no planning permission is needed for balcony roof repairs.

However, flats, listed buildings, or shared balconies may require approval from the freeholder or building management.
