Take the Pressure Out...
DiPonzio's uses the ARMA (Asphalt Roofing Manufacturers Association) method of non-pressure roof cleaning.
Your roof will be cleaned in the safest manner possible without pressure. And unlike most companies, DiPonzio's PROTECTS YOUR PLANTS WITH TARPS.
Washing with a high pressure system is likely to cause damage to asphalt roofing and should not be used.
The Pitfalls of Pressure Washing Roofs:
Pressure washing does not kill mildew & algae spores - it only temporarily removes stains
Pressure forces water where it shouldn't be, creating leaks that can lead to costly repairs
Pressure discolors tile roofs, removes glaze & loosens mortar from joints, ridges & end caps
High pressure blows off the granules taking years of life off your roof
Pressure only lasts about 1 year...NON-Pressure will last 3-5 years!
Don't let this happen to your roof!
