Does pressure washing damage my roof?

Pressure washing reduces shake thickness. If the roof is 1 - 10 years old, typically the roof is okay to wash. Roofs 11 years of age and older are determined on a case-by-case basis. Air cleaning, however, is the least abrasive of all cleaning methods.

Does walking on my roof damage it?


Is it better to wait for summer to do maintenance on my roof?

No! Fenix Roof Wash works year-round. There are many steps to the maintenance of a roof (clean, repair, treatment). A cedar shake roof takes one day to two weeks to complete. A composition roof, however, typically takes one day to complete. All Fenix Roof Wash services are warrantied to give you a worry-free experience.

Is roof treatment really necessary?

If you want to save thousands of dollars by not replacing your roof, you must have a maintenance program. Having oil in your engine is the equivalent of having treatment on your roof.

What damages my roof the most?

  1. 1. Sun (dries every material out, even tile)
    2. Moss (eats away roof material)
    3. Debris (rots roof material)

How often should I have a roof washed?

Every three to five years, depending on accumulated roof debris. For homes near trees, a roof blow-off and gutter cleaning would be recommended once per year in most cases.
