DIY vs Pro at a glance
| Factor | DIY | Professional |
|---|---|---|
| Method & water | Tap water; basic brush/squeegee | DI/RO water + soft‑bristle flow‑through brushes |
| Safety | Limited PPE; ladder risk | Harnesses, ladder stabilizers, insured crews |
| Time & effort | Longer; learning curve | Fast, repeatable process |
| Risk to panels/roof | Higher if using pressure washers or hard water | Low: gentle methods; trained handling |
| Proof of results | Visual check only | Before/after photos; notes on issues spotted |
| Typical cost | Low out‑of‑pocket if gear exists | Service fee; 25% off second cleaning |
When DIY makes sense
- Easily accessible, single‑story roofs with gentle pitch.
- Short panel runs near a hose connection and no tight valleys.
- Comfortable with ladders and basic fall safety.
Avoid pressure washers and harsh detergents. If using tap water, finish with a light DI rinse (if available) to minimize spotting.
When to hire a professional
- Two‑story access, steep or fragile tiles, complex roof lines.
- Heavy soiling (ash, sap, bird debris) or performance drop.
- Need for quick turnaround, photo proof, or routine maintenance.
Balancing cost and value
Consider the value of recovered production and your time. Pros bring DI systems, soft brushes, and experience that reduce risk and often improve output more consistently. Booking a bi‑annual plan simplifies upkeep—and we offer 25% off the second cleaning when booked together.
Prep tips (either route)
- Clear access (gates, pets, parked cars) and note outlets/spigots.
- Check forecast; avoid peak heat and high winds.
- Have a simple checklist: panel count, roof notes, and any issues to photograph.
Bottom line
DIY can work for simple, safe setups. For many homes, professionals deliver faster, safer, and more consistent results. Choose the route that fits your roof, tools, and schedule.
