Why metal wins under trees
Moss needs a rough, absorbent surface to take hold. A standing-seam panel gives it nothing, and debris slides off instead of damming at the course line — the exact failure that kills composite roofs on shaded lots.
Metal Roofing in Western Washington
Metal costs more on day one and less over thirty years. It sheds moss and fir needles instead of holding them, handles uplift far better than composite, and is the right answer for shops, barns and exposed valley properties.

Metal Roofing questions
- Is a metal roof loud in the rain?
- Not over a solid deck with underlayment and an insulated attic. The noise complaint comes from bare panels on open purlins.
- Can you put metal over my existing shingles?
- Sometimes, but we usually recommend a tear-off so we can see and fix the deck.
