Four different jobs
These barely resemble each other in practice. Knowing which one you have saves a week of talking past each other.
One of these is a construction project, one is a diagnosis, one is an insurance conversation and one is cosmetic maintenance that half the valley mistakes for a dying roof.
Replacement
A two to four day construction project, where the decisions that matter are all invisible by the end of day one.
Leak repair
Almost never the roof. Almost always one detail, and finding it is most of the job.
Storm damage
More often wind, debris and the tail of a Gulf system than the hail that dominates further west.
Algae and streaking
The black streaks on half the north slopes in the valley. Living, mostly cosmetic, and routinely mistaken for a dying roof.
