Southern Wisconsin’s cold, wet climate is hard on a roof. The damp keeps organic growth alive year after year, and algae, mold, and especially moss take hold on shingles all over the area. That growth does more than darken the surface. It holds moisture against the shingles and works its way in over time, so clearing it early protects the life of the roof.
At Jet Wash Exterior Cleaning, we clean roofs with no high pressure at all. Our soft-wash method lifts the moss and algae with the right cleaner instead of force, so the growth comes off while the protective granule layer on your shingles stays put. That is the whole point of how we work: get the roof clean and leave the surface it depends on intact.
If your roof has gone green or dark and you want it handled the safe way, call us at (608) 577-9681 and we’ll walk you through it.
