Flat Roof Maintenance Tips
Preventive maintenance helps prolong the lifespan of your flat roof and minimizes repair costs. Follow these tips to avoid damage:
- Clear Debris Regularly: Remove leaves, branches, and other debris that can block drainage and cause water pooling.
- Inspect After Storms: Check for cracks, loose flashing, or punctures after storms or heavy winds.
- Clean Gutters and Drains: Ensure gutters and downspouts are clear to prevent water from overflowing onto the roof.
- Limit Foot Traffic: Avoid walking on your flat roof unless necessary, and use protective boards if access is required.
- Annual Inspections: Schedule a professional inspection annually to identify potential issues before they escalate.
Cost of Flat Roof Repairs
The cost of flat roof repair depends on the extent of the damage and the materials used:
- Patch Repairs: £100 – £300 (for minor cracks or punctures).
- Sealing with Liquid Coating: £500 – £1,000 (depending on roof size).
- Membrane Replacement: £1,000 – £3,000 (for partial section repairs).
