Polycarbonate Roof & Panel Cleaning — What to Expect

We were asked to clean a polycarbonate roof that looked like it needed a simple wash. From the ground, it seemed like a normal window/surface job. Once we started, we saw the real issue: the panels were very old and worn. Tiny cracks let in moisture, dust, and algae spores over time.

What We Did

• Gentle exterior clean: pro tools, soft brushes, no harsh pressure.
• Better surface look: the roof looked cleaner and more even after washing.
• Limits showed up: the inside of the panels stayed cloudy and stained.

Why? Because the dirt wasn’t only on the surface — it was inside the polycarbonate layers.

What You Can’t Clean Out of Old Polycarbonate

Even with professional cleaning, we can’t restore factory transparency if the issue is internal. Typical causes:

• Micro-cracks & UV wear: they let moisture and fine dust in.
• Trapped growth: algae/biological film inside the channels.
• Material aging: yellowing or haze within the plastic itself.

Cleaning services remove outside dirt, algae, and buildup. Internal discoloration and moisture damage cannot be washed away.

Before You Book Polycarbonate Cleaning, Consider

• Age: older panels get cloudy and brittle with UV and time.
• Damage: cracks or holes allow dirt and moisture inside.
• Expectations: washing improves appearance, but won’t “re-make” degraded plastic clear.

Our Promise: Clear, Honest Expectations
