Is $725+tax for roof moss + gutter cleaning reasonable? 1900 sqft two storey house

Just had a roof moss + gutter cleaning and it cost me $725+tax. There is moderate moss on the roof so the technician brushed the moss off then applied chemicals. He also cleaned the gutter and removed the debris from my yard.

I think he did a good job cleaning, but I wonder if the price is reasonable. Any recommendations for gutter cleaning in Seattle area?
