Do you pressure wash asphalt shingles?
Roof work is matched to the roofing material and condition. We do not treat a roof like concrete; the goal is to remove or treat growth without unnecessary force.
Will every patch of moss disappear the same day?
Not always. Some roof treatments continue working after the visit, and dead growth can loosen gradually. We explain the expected timeline for your roof before the job.
Can roof care be part of the annual plan?
Yes. Routine roof blowoff and roof-safe wash or check can be scheduled within Complete Home Care. Heavier moss remediation is confirmed separately before extra work.
