If you’re a homeowner wondering whether you can clean your roof yourself instead of hiring a professional, you’re not alone. DIY roof cleaning can seem like a great way to save money. But before grabbing a ladder and a bottle of bleach, it’s essential to understand the risks, effectiveness, and long-term costs of doing it yourself.
In this post, we’ll break down everything you need to know about DIY roof cleaning, including the pros, cons, safety concerns, and when it’s best to call in a company for a professional roof cleaning service.
Why People Want to Clean Their Own Roofs
Let’s be honest moss, algae, and stains on your roof aren’t just unsightly. They make your home look aged and poorly maintained. And with online tutorials and cleaning products easily available, DIY seems like a quick win.
But just because you can doesn’t always mean you should.
The Real Risks of DIY Roof Cleaning
1. It’s Dangerous
Climbing on your roof with wet, soapy surfaces and cleaning equipment is extremely risky. Most homeowners don’t have the safety gear or training to move around on roofs safely. Every year, thousands of people are seriously injured in falls while attempting home maintenance.
Steep pitches, wet moss, and fragile tiles create a perfect recipe for accidents. No discount is worth risking a trip to A&E.
2. You Might Damage the Roof
It’s a common misconception that using a pressure washer will blast away all the moss and dirt quickly. While that’s true, it can also:
- Strip away the protective top layer of roof tiles
- Force water under tiles, leading to internal leaks
- Dislodge tiles and flashings, causing expensive future repairs
Even using a standard hose with the wrong chemicals can weaken materials or void your roof warranty.
3. Ineffective Cleaning (Short-Term Wins, Long-Term Losses)
DIY methods often involve household bleach, vinegar, or over the counter cleaners that may seem to work, but only on the surface.
Without professional-grade biocide treatments (used by certified cleaners), you won’t kill the root systems of moss and lichen. This means it comes back faster, thicker, and more stubborn than before, costing you more in the long run.
What Professionals Do Differently
At JM Exterior Cleaning, we’ve helped hundreds of homeowners inEdinburgh, West Lothian, and the surrounding areas restore their roofs in a safe and effective way.
Here’s how we approach it:
Steam Cleaning (Soft Wash)
We use low-pressure steam cleaning to gently remove organic growth without damaging your tiles. This method is safe, efficient, and ideal for delicate roofs.
Biocide Application
After cleaning, we apply an industry-grade biocide that kills remaining spores and helps prevent future moss and algae regrowth for years not weeks.
Full Rinse & Rubbish Removal
We never leave behind a mess. All moss, debris, and waste are cleared from gutters, paths, and gardens.
DIY vs Professional Roof Cleaning: Quick Comparison
| Aspect | DIY | Professional |
|---|---|---|
| Safety | ❌ High risk | ✅ Fully insured & trained |

| Risk of Damage | ❌ High | ✅ Very low |

So, Should You DIY?
If your roof just has some loose leaves or light dust, a long-reach brush or gutter vacuum might be fine.
But if you’re dealing with:
- Moss
- Lichen
- Black streaks
- Discolouration
- Persistent algae growth
…it’s worth investing in a professional roof clean. Not only does it improve your home’s kerb appeal, but it extends the lifespan of your roof, boosts energy efficiency, and protects your home from future damage.
