Roof Moss Removal & Treatment
Shaded roofs under firs and cedars grow moss that lifts shingle edges.
DetailsGraham sits farther south and east of Tacoma than Parkland or Spanaway, in unincorporated Pierce County. Where trees stand close to a house, they shape most of the roof work we do.

Short answer
Graham is unincorporated Pierce County, a longer drive from Tacoma than Parkland or Spanaway. Where tall trees stand close to a house, moss, needles and limb strikes are the problems we check first. The county's reroof rule covers detached garages as well as homes, which matters on properties with more than one roof.
OSU Extension describes roof moss as a shade problem: it grows where the roof stays damp, holds moisture against the shingles and can lift their edges. Seattle Public Utilities adds that moss revives with the fall rains and is most visible from early winter to late spring.
On a property where firs or cedars shade the roof for much of the day, a moss treatment alone buys time but rarely ends it. Trimming branches back so sun and air reach the roof is the long-term fix. Until then, we hand-scrape moss, clean the valleys and treat the surface to slow regrowth.
One caution if your gutters are copper: zinc treatments corrode copper. We pick a treatment that suits the metal on your house.
February 2019 brought nearly 8 inches of snow to Sea-Tac, the snowiest February since 1949, and crews spent days clearing fallen trees around Tacoma. Wet snow loads branches until they break, and a heavy limb landing on a roof can crack rafters as well as shingles.
If a limb comes down on your roof, take photos from the ground, keep people out of the rooms below and call any hour. We tarp the opening and look at the framing from the attic before planning the repair. Our storm guide covers what to check from the ground after any big storm.

With 32,658 residents spread across unincorporated land, Graham properties often have more than one roof to think about. Pierce County needs no building permit to reroof a home or garage steeper than 2:12 if the coverings total 7.5 pounds per square foot or less. The rule names homes and garages, so ask the county before assuming it covers a barn or large shop.
Outbuildings are where metal roofing often makes sense. It sheds needles and snow well and handles a lower pitch than shingles. Whatever the material, replacing sheathing is not exempt under the county rule, so we check the decking before we quote.
