Roof Coating services in Singapore involve applying specialized protective layers (often elastomeric, silicone, acrylic, polyurethane, or cool roof formulations) over existing roofs to restore waterproofing, reflect heat, extend lifespan, and prevent leaks. This is a popular, cost-effective alternative to full re-roofing for flat RC roofs, tiled roofs, metal roofs, and other substrates in HDB top-floor units, condos, landed homes, commercial buildings, and industrial facilities. In Singapore’s hot, humid, rainy climate, roof coatings combat UV degradation, ponding water, cracking, and corrosion while providing energy savings through solar reflection.

Buildbest Roofing & Construction Pte Ltd offers professional roof coating as part of their comprehensive roofing and waterproofing services. With nearly 40 years of combined team experience, they apply high-performance coatings using airless spray techniques for even coverage, durability, and minimal disruption—ideal for both restoration and preventive maintenance.

Popular Types of Roof Coating in Singapore

• Silicone Roof Coatings — 100% silicone; highly waterproof, UV-stable, flexible; excellent for flat roofs and restoration.
• Acrylic Roof Coatings — Water-based; cost-effective, easy application; often ceramic-fortified for heat reflection and dirt resistance.
• Elastomeric Roof Coatings — Rubber-like flexibility; bridges cracks, withstands movement; good waterproofing and UV protection.
• Polyurethane (PU) Roof Coatings — Tough, durable; high abrasion/chemical resistance; often used for industrial or high-traffic roofs.
• Cool Roof / Solar Reflective Coatings — High SRI (Solar Reflectance Index) formulations; reflect sunlight/IR rays to reduce heat absorption (e.g., RD-Sunguard or similar waterborne options).
• Ceramic-Fortified Acrylic — Enhanced with beads for superior heat reflection, fungus control, and longevity (e.g., WAPOL CFA).

Key Features of Professional Roof Coating

• Solar Reflectance & Cool Roof Properties — High reflectivity (albedo 0.70–0.90+); reduces roof surface temperature by 10–20°C, lowering indoor heat.
• Waterproof & Seamless Membrane — Forms a continuous, breathable barrier; prevents leaks while allowing trapped moisture to escape.
• UV & Weather Resistance — Blocks harmful rays; resists cracking, peeling, chalking in intense sun/rain cycles.
• Flexible & Crack-Bridging — Elastomeric properties accommodate thermal expansion/contraction without failing.
• Low VOC & Eco-Friendly — Water-based options minimize odor/disruption; many are green-certified.
• Easy Application — Airless spray for uniform coverage; quick curing (hours to days); low-maintenance post-application.
• Anti-Microbial & Self-Cleaning — Reduces algae/mold growth; dirt pickup minimized for longer clean appearance.
• Fire-Retardant Options — Enhances roof fire rating in some formulations.

Benefits of Roof Coating in Singapore

• Extends roof life by 10–20+ years; delays expensive re-roofing.
• Significant energy savings — lowers air-con usage by reducing heat gain (studies show 15–35% cooling cost reduction in tropical climates).
• Prevents leaks, mold, efflorescence, and interior damage.
• Improves indoor comfort and productivity with cooler spaces.
• Cost-effective (often 30–60% cheaper than full replacement).
• Enhances aesthetics (restores faded roofs; available in various colors).
• Reduces urban heat island effect; contributes to greener buildings.
• Minimal disruption — no major demolition; suitable for occupied properties.

Typical Roof Coating Process with Buildbest

1. Free Site Inspection — Assess roof condition, leaks, substrate; thermal/moisture checks.
2. Surface Preparation — High-pressure cleaning, repairs (cracks/seals), priming.
3. Application — Primer coat + 1–2 topcoats via airless spray; focus on seams/flashings.
4. Curing & Testing — Allow drying; optional flood test for waterproofing verification.
5. Handover — Cleanup, warranty docs (often 5–15+ years), maintenance tips (e.g., periodic cleaning).
