Flat Roof Maintenance Guide
A flat roof can be a smart and cost-effective choice for many homeowners, but like any part of your home, it requires proper care to stand the test of time. Whether you've recently installed a flat roof or you’ve had one for years, regular maintenance is key to preventing costly repairs and prolonging the lifespan of your roofing system.
Why Flat Roof Maintenance Matters
Flat roofs are more susceptible to water pooling, debris accumulation, and weather-related wear. Routine inspections and upkeep can help you spot early signs of damage, avoid leaks, and maintain your home’s energy efficiency.
1. Inspect Your Flat Roof Regularly
Check your roof at least twice a year — ideally in the spring and autumn — and after major storms. Look out for:
- Standing water or pooling
- Cracks, splits, or blisters in the membrane
- Loose or missing flashing
- Signs of moss or algae growth
- Blocked drainage outlets
2. Clear Debris and Clean the Surface
Leaves, branches, and dirt can clog your drainage and cause water buildup. Use a soft broom or brush to clear debris gently. Avoid pressure washers as they can damage the surface membrane.
3. Check and Maintain Drainage
Ensure all outlets, scuppers, and gutters are clear of blockages. Poor drainage is a leading cause of leaks and water damage in flat roofing systems.
4. Address Small Repairs Promptly
If you notice minor damage — like a small tear or blister — get it repaired before it worsens. DIY patch kits can work for very small fixes, but always consult a professional for larger issues.
5. Look After Surrounding Features
Check adjacent features like skylights, vents, and chimneys. Sealant around these areas can wear out and become entry points for moisture.
6. Schedule an Annual Professional Inspection
A qualified roofer can spot underlying problems you might miss. At Armstrong Roofing, we offer comprehensive flat roof inspections and maintenance plans to give you peace of mind.
