When was the last time you looked up at your roof and thought, “Wow, that looks clean”? Probably not recently, right? Most of us spend plenty of time cleaning the inside of our homes but forget that the outside needs love too. One of the most ignored areas? The roof. Keeping your roof clean isn’t just about appearance. It’s about protecting your home. Dirt, algae, and moss can slowly eat away at your shingles, causing damage that’s expensive to fix. That’s why learning how to clean your roof shingles properly is so important.

If you live in Surrey, you’ve probably noticed how fast roofs can collect grime, especially during the rainy months. Let’s go over some smart and safe ways to clean your roof shingles.

Why Cleaning Your Roof Shingles Matters

Your roof isn’t just a cover for your home; it’s your first line of defense against the elements. Over time, leaves, dirt, algae, and moss can build up. When that happens, your shingles can trap moisture, leading to leaks, mold, and even structural damage.

A dirty roof can also make your house look older than it is. Regular cleaning gives your home that fresh, well-kept look that everyone appreciates. It also helps you catch early signs of damage before they become big problems.

Step 1: Remove Black Streaks

If you’ve seen black streaks running down your roof, that’s not dirt. It’s algae, specifically, a type called Gloeocapsa magma. It spreads through the air and loves humid environments.

You can remove these streaks with a chemical cleaner made for roofs. Spray it on, wait for about 15–20 minutes, and rinse it off gently with a garden hose.

Bleach mixed with water can also do the trick, but use it carefully. Too much bleach can harm your plants or damage your roof if not rinsed properly. Always protect your landscaping before starting.

Step 2: Get Rid of Moss

Moss looks soft and harmless, but it’s one of the worst things for your shingles. It traps moisture and can lift the shingles, making room for water to seep in.

You can scrape off moss carefully with a roof brush or plastic scraper. But that’s hard work and time-consuming. Another option is to use a moss-killing solution available at hardware stores. Spray it, let it sit for a while, and rinse it off.

A mixture of diluted bleach and water can also help remove moss, but again, rinse thoroughly. Avoid harsh scrubbing; it can damage the shingles.

If the moss keeps coming back, you might want to install zinc or copper strips along the ridge of your roof. When it rains, metal ions wash down and stop moss and algae from growing again.

Step 3: Avoid Pressure Washing

Many homeowners think pressure washing is a quick fix. It’s fast and powerful, but it can also be risky. The strong water pressure can loosen or crack shingles, making your roof more vulnerable to leaks.

Unless your roof is extremely dirty and you know what you’re doing, it’s best to avoid pressure washing. Instead, use a low-pressure garden hose to rinse after applying a cleaner.

If you do choose to pressure wash, keep the nozzle at least a few feet away from the surface and aim downward to avoid forcing water under the shingles.

Step 4: Gather the Right Tools

Cleaning your roof isn’t a job to rush through. Having the right tools makes all the difference. Here’s what you’ll need:

• A sturdy ladder
• A garden hose
• A cleaning solution or roof cleaner
• A spray bottle or sprayer
• A soft brush or scraper
• Safety gear (gloves, non-slip shoes, safety harness)

Always prioritize safety. Never climb your roof when it’s wet or windy. If the slope is too steep, it’s better to hire professionals like Sweepy Scrub who have the right training and equipment.

Step 5: Schedule Regular Cleaning

Your roof doesn’t need cleaning every month, but it should be done at least once or twice a year. The best time is during spring or early summer when the weather is dry and mild.

Regular maintenance keeps your roof looking new and prevents buildup before it gets out of hand. It’s also a great chance to check for missing shingles, cracks, or any early signs of damage.

If you can, plan to clean your roof shingles routine along with your exterior house cleaning in Surrey. That way, the entire outside of your home stays spotless, from the walls to the gutters to the roof.

Step 6: Know When to Call the Pros

• Keep gutters clean to prevent water buildup.
• Install zinc or copper strips to stop algae and moss from growing again.
• Check your roof after heavy storms or rain.

A little prevention goes a long way. By keeping up with maintenance, you’ll save money on costly repairs later to clean your roof shingles.
