Thick Roof Moss Is More Than an Appearance Problem
Your roof used to look clean. Now the concrete tiles are covered in green moss, stubborn lichen and dark organic growth.
Some areas may have thick clumps forming around tile overlaps, ridges and shaded sections.
Ignoring it can become expensive.
Moss holds moisture against roofing materials. Heavy growth can contribute to deterioration, interfere with drainage and conceal existing damage.
And when growth returns season after season, the problem becomes harder to ignore.
But aggressively water blasting your tiles can create another risk.
Concrete roof tiles can become fragile as they age. Poor cleaning techniques may damage protective coatings, dislodge tiles or push water into vulnerable areas.
You need a targeted treatment that addresses the organic growth without unnecessary force.
DryGutts provides professional roof moss and lichen treatments for Hamilton homeowners. Our approach focuses on treating the growth at its source, rather than simply blasting away what's visible.
How Our Concrete Tile Roof Treatment Works
1. Assess the Roof and Existing Growth
We review your roof's condition, tile type, access requirements and visible moss coverage. We identify areas requiring additional care before recommending an appropriate treatment.
2. Apply a Targeted Moss and Lichen Treatment
Our team uses professional roof treatment products and controlled application methods. We take precautions around surrounding gardens, drainage and rainwater collection systems.
3. Allow the Treatment to Work
Unlike aggressive pressure cleaning, moss treatment works progressively.
Moss and lichen begin dying after application. Dead growth then breaks down and washes away over time through natural weathering.
Results are not instant, particularly where growth is heavy.

Treat the Moss Before It Creates Bigger Problems
Heavy moss rarely disappears permanently on its own.
The longer organic growth remains untreated, the longer moisture can sit against your roofing materials.
