DIY Roof Cleaning: The Upsides and the Downsides

Pros of DIY Roof Cleaning

Cost Savings

Initially, DIY seems cheaper because you avoid labor fees.

Flexible Timing

You can clean your roof whenever you find the time without booking a service appointment.

Cons of DIY Roof Cleaning

Serious Safety Risks

Roof cleaning is dangerous—especially on steep, wet, or slippery surfaces.

  • Ladder falls are a leading cause of home injuries.
  • Slippery moss and wet tiles are serious hazards.
  • Roofs higher than a single storey require specialist equipment for safe access.

Inadequate Equipment

Most homeowners don’t own industrial-grade water blasting machines or biodegradable moss treatments.

  • Garden hoses and domestic pressure washers don’t clean deeply enough.
  • DIY methods often leave moss roots behind, leading to rapid regrowth.

Potential Roof Damage

Using incorrect pressure or poor techniques can:

  • Crack tiles or dislodge shingles
  • Force water under roofing materials, causing leaks
  • Strip protective coatings off roofs

Incomplete Cleaning

DIY cleaning often misses hidden moss patches, clogged gutters, and early signs of corrosion.

Common DIY Roof Cleaning Mistakes We See in Auckland

Using the Wrong Pressure Settings

Too much pressure strips tile coatings or cracks asphalt shingles.

Standing in Unsafe Positions

Homeowners overreach or walk on fragile tiles, leading to slips and broken roofs.

Ignoring Small Moss Patches

Leaving moss behind allows it to regrow quickly and cause hidden structural problems.

Inadequate Rinsing

DIY jobs often leave soap, moss spores, or salt residues that continue damaging the roof.

When DIY Might Be Acceptable

DIY roof cleaning might be suitable if:

  • You have a small, single-storey home.
  • Your roof has minimal debris or no heavy moss.
  • You have proper safety gear (harnesses, roof anchors).
  • You are experienced and confident working at heights.

(Still, even then, scheduling professional roof cleaning once a year is highly recommended.)

Why Auckland’s Coastal Homes Should Avoid DIY Roof Cleaning

If you live anywhere near the sea — from North Shore to West Auckland — you are dealing with:

  • Higher salt exposure
  • Increased organic growth rates
  • Faster material corrosion

Professional roof washing is necessary to properly remove these elements without harming your roof.
