Smart Tips to Make Your Roof Look Like New

Let’s face it—your roof takes a beating. Between valley heat, airborne dust, and seasonal moisture, it’s no surprise those dark streaks and moss patches creep in. Whether you live in Northridge, Sherman Oaks, Woodland Hills, or Van Nuys, roof washing is one of the most impactful (and overlooked) home maintenance tasks.

We’ve compiled the most effective techniques to help your roof look brand new—without damaging shingles or putting yourself at risk. Let’s dive into the best practices for keeping your roof in top shape

1. Know What You’re Dealing With

Not all roof grime is created equal. Most staining is caused by Gloeocapsa magma, a type of algae that thrives in humid or shaded parts of the Valley, especially under overhanging trees and in areas with poor drainage. Left untreated, it can damage shingles and lower your home’s curb appeal.

If you spot:

• Black streaks – likely algae
• Green fuzz – moss or lichen
• Heavy buildup – debris from wind, trees, or pollution

…it’s time to call in the pros—or follow the steps below.

2. Skip the Pressure Washer (Seriously!)

High-pressure washing might feel satisfying, but it can shred shingles and void your roof warranty. Instead, opt for a low-pressure soft wash, which uses eco-friendly detergents to lift grime gently.

At Neon Clean, we use a soft wash system specifically designed for the roofing materials common in the San Fernando Valley—no damage, all shine.

3. Use the Right Cleaning Solution

For DIYers, a safe and effective solution is:

• 1 part bleach
• 1 part water
• A squirt of biodegradable dish soap

Spray the mix on a cool, overcast day (or early morning) to prevent evaporation. Let it sit for 15–20 minutes, then rinse thoroughly with a garden hose.

Protect your plants—cover them before spraying or rinse immediately afterward.

4. Safety First: Roof Work Isn’t a Solo Job

Climbing on your roof? Only do so with:

• A secure ladder
• A harness
• A buddy on the ground

If your roof is steep or slippery, leave it to professionals. A roof washing service like Neon Clean in San Fernando Valley ensures safety and results.

5. Regular Maintenance Pays Off

Washing your roof once a year keeps algae and moss from taking hold—and saves you big on long-term repairs.

Here’s a good roof care checklist for SFV homeowners:

• Clear off debris every season
• Trim overhanging branches
• Check for broken or curling shingles
• Schedule a professional soft wash yearly
