Joseph’s field notes · Practical advice
The moss matters. So do the shingles underneath it.
Before we celebrate what came off, let’s think about what we’re trying to keep.
Have a closer look
In this video I’m looking at growth spreading across the shingle surface. What catches my attention is the way it sits around the granules. That changes how I think about physically removing it.
The moss is visible, so it’s easy to make it the entire focus. But you paid for the roofing material underneath it. That needs our attention too.
Every extra pass needs a reason
Scrubbing can remove protective shingle granules. IKO explicitly warns about that in its moss-removal guidance. So I’m interested in the buildup that needs addressing and the treatment options for the remaining growth.
I don’t need to give you a dramatic number for how many granules might come off. The practical question is whether more contact with the shingles is justified.
At what cost?
Installation, upkeep, eventual replacement and waste all belong in the conversation. I want the decisions we make on a maintenance visit to respect the material you already have.
That’s what I mean by preservation. We look at the growth and the roof together, and explain why we’ve chosen a stopping point.
