Does sweeping the roof remove granules from the shingles?
I have a large tree that overhangs the back side of my roof.
The roof was installed in 11/2009. It was swept once about a year later when a roofer fixed a leak at a vent flashing. Over the last 4 years it has gotten a lot of leaves and broken twigs and debris on it from the tree.
I went up to sweep it about 2 weeks ago. Was that a mistake?
Did i remove a lot of granules in the process?
