Turf roofs have been part of Norwegian building tradition for thousands of years. The living roof provides natural insulation, dampens sound and fits perfectly into Norwegian nature. With proper maintenance, a turf roof can last for many decades.
Annual inspection is key
Inspect the roof thoroughly at least twice a year – spring and autumn. Look for signs of erosion, areas where the turf has slipped, or places where weeds have taken over. Early detection of problems makes repair easier and cheaper.
- •Check that the drainage is working optimally
- •Remove leaves and twigs that have accumulated
- •Look for signs of moss or lichen growth
- •Check that the gutters are clean
- •Inspect penetrations and flashing
Managing vegetation
A healthy turf roof should have lush growth of grass and herbs, but no trees or large shrubs. Trees that take root can damage the roof membrane and must be carefully removed. Lack of growth is often a sign of too much shade or moisture.
Fertilising and maintenance
Most turf roofs need fertilising every 2-3 years to maintain lush growth. Use a fertiliser suited to grass growth, and apply it early in spring. Avoid overwatering – turf roofs should be able to withstand drought, and too much moisture can lead to fungal growth.
When should you call in professionals?
Some tasks require professional help. If you notice leaks, large areas of damaged turf, or if the roof starts to slip, you should contact a specialist. We offer inspection and maintenance services for all our customers.
