Flexible Ridge & Hip Mortar for Clay Roof Tiles
We recommend Flexim® as a faster, cleaner alternative to traditional sand and cement mortar.
What is Flexim Roof Mortar
When installing ridge and hip tiles on a clay roof, choosing the right mortar is essential.
We recommend Flexim®, a ready-to-use flexible ridge tile mortar designed as a long-lasting alternative to traditional cement mortar systems.
At Northern Roof Tiles, we’ve recommended Flexim for years because it reduces installation time while improving long-term performance.
Why We Recommend Flexim for Clay Roof Ridges
After decades working with clay roof systems, we’ve seen how traditional cement mortar can crack and fail over time — especially in changing climates.
That’s why we recommend Flexim for ridge and hip installations.
It comes ready to use, requires no on-site mixing, and becomes waterproof immediately. Unlike rigid cement mortar, it remains permanently flexible, allowing the roof to move naturally without cracking.
For installers, it’s faster and cleaner.
For homeowners, it provides long-term reliability.
