Est: RM300-450
Professional roof cleaning costs vary based on the cleaning method, roof size, height, and soiling condition. Here are the average rates for 2026:
RM0.18 - RM0.30/sq ft
Min charge: RM300
Fast & effective for most roofs
RM0.22 - RM0.38/sq ft
Min charge: RM350
Gentle, kills moss/algae at root
RM0.25 - RM0.40/sq ft
Min charge: RM400
Gentlest, best for fragile roofs
Double-storey homes add 20% and triple-storey homes add 40% due to increased difficulty and safety equipment requirements. Heavy moss or lichen adds up to 50% to the base price.
Larger roofs cost more but have lower per-sq-ft rates. Concrete and clay tile roofs are the most common in Malaysia and easiest to clean. Metal roofs require lower pressure to avoid denting. Asphalt shingles need the gentlest approach to avoid granule loss.
Higher roofs cost more due to safety equipment (scaffolding, harnesses), longer hose runs, and increased risk. Single-storey roofs are the base rate, double-storey adds 20%, and triple-storey or bungalows add 40%.
Light dust and dirt is quickest to clean. Moderate moss and algae buildup requires pre-treatment and multiple passes (+25%). Heavy black stains and lichen are the hardest to remove, often requiring specialised chemicals and extended treatment time (+50%).
Pressure washing is the most affordable and fastest. Soft washing costs more due to chemical solutions but is safer for older roofs. Manual scrubbing is the most labour-intensive and expensive but causes zero risk of pressure damage.
Anti-moss treatment extends the time between cleanings by 1–2 years. Roof coating/sealant protects against UV damage and water absorption. Gutter cleaning and roof inspections are commonly bundled for a complete roof maintenance package.

Recommended: Pressure washing for general dirt, soft washing for moss/algae. These are the most durable roof tiles and can handle moderate pressure (1,500–2,500 PSI). Avoid very high pressure on old tiles that may be cracked or loose. Clean every 2–3 years.
Recommended: Soft washing or low-pressure washing. High pressure can dent metal panels and strip protective coatings. Metal roofs are naturally resistant to moss but accumulate dirt and oxidation. Clean every 3–5 years. Consider roof coating to restore shine.
Recommended: Soft washing only. Never pressure wash asphalt shingles — it strips the protective granules and shortens roof life by years. Soft wash chemicals safely remove algae stains (those black streaks) without physical damage. Clean every 2–3 years.
Recommended: Pressure washing or manual scrubbing. Flat roofs accumulate standing water and debris, making them prone to algae and moss. Regular cleaning every 1–2 years prevents water damage. Always check for drainage issues during cleaning.
Recommended: Manual scrubbing or very low-pressure wash. These materials scratch easily and can become cloudy if cleaned aggressively. Use soft cloths and mild detergent. Clean every 1–2 years to maintain light transmission for car porches and skylights.
Green patches indicate moss or algae growth. Black streaks are usually caused by Gloeocapsa magma, a type of blue-green algae. Both retain moisture and accelerate roof deterioration if left untreated.
Blocked gutters and moss-covered tiles can redirect water flow, causing leaks. If you notice water stains indoors, your roof likely needs cleaning and inspection before it becomes a costly repair.
Gradual darkening is caused by accumulated dirt, pollution, and organic growth. You may not notice it daily, but compare with old photos — the difference is often dramatic. Clean roofs also improve your home's kerb appeal.
If similar homes in your area look cleaner, your roof is probably overdue for a wash. In Malaysia's tropical climate, most roofs need cleaning every 2–3 years. Don't wait until moss is visible from the ground.
A dirty roof absorbs more heat. Moss and algae act as insulation in the wrong way — they trap heat in your roof space, making your air conditioning work harder. A clean roof can noticeably reduce indoor temperatures.
⚠️ Safety warning: We strongly recommend professional roof cleaning. Falls from roofs are a leading cause of serious injuries in Malaysia. The cost difference does not justify the risk of climbing onto a wet, slippery roof without proper safety equipment and training.
