Why Flexim Roof Mortar May Appear to Fade Over Time — and Why That’s Actually a Good Thing
When you first install Flexim Roof Mortar, the vibrant color and clean finish stand out immediately. But over the months and years, you might notice the color softens slightly. This isn’t a sign of product failure — it’s a completely natural and expected part of how Flexim weathers outdoors.
Understanding the Subtle Change
Flexim is made with natural linseed oil and mineral pigments, designed to cure and harden without cracking. Because it’s a natural product, the surface can slowly pick up a fine layer of dust, dirt, and environmental pollution. This thin film dulls the initial brightness, giving the mortar a softer, more integrated look that blends beautifully with your roof tiles.
In most climates, this mellowing effect happens gradually and evenly, helping new repairs or installations blend with existing roof sections. Rather than looking freshly patched, Flexim develops a natural patina — similar to how clay tiles, brick, or copper gain character over time.
Why the Color Doesn’t Actually “Fade”
It’s important to note that the pigments in Flexim don’t bleach or fade from sunlight. The base color remains intact beneath the surface layer of dirt. In fact, if you wipe or gently clean a small area with mild soap and water, you’ll see the original tone return almost immediately.
This means the color change is cosmetic and reversible, not a sign of aging or product deterioration.
Real-World Advantages
Natural appearance: Blends seamlessly with traditional roof tiles.
Low maintenance: No need for repainting or sealing.
Weather-resistant: Stays flexible even as temperatures change.

Keeping Your Roof Looking Its Best
If you prefer to restore the original color tone, a light rinse or soft brush cleaning once a year will do the trick. But most homeowners find that letting the mortar weather naturally creates a more authentic, established look that complements older clay tiles.
