What is Roof Repairing , Waterproofing Specialist Works
Quick‑look Guide to Singapore Roof Care
| Topic | What it means | Why it matters |
|---|---|---|
| Roof waterproofing | A protective layer that keeps water out of the roof deck. | Prevents leaks, mould, and structural damage. |
| Structural repair works | Fixing or reinforcing the roof’s load‑bearing elements (beams, trusses, joists). | Keeps the building safe and prolongs its life. |
| Concrete repair | Filling cracks, patching spalling, or applying a new concrete overlay. | Stops water ingress and stops further deterioration. |
| Water leakages | Water finding its way onto the interior – often a symptom of hidden damage. | If ignored, can turn a small problem into a costly disaster. |
1. Spotting the Signs
| Symptom | What’s likely wrong? | Quick fix |
|---|---|---|
| Damp patches on ceilings | Seepage through roof or walls | Inspect roof eaves, flashings, and drains |
| Cracked or peeling tiles | Falling tiles expose the membrane | Replace or re‑seal damaged tiles |
| Persistent mould or mildew | Water trapped in roof deck | Drainage fix + mould remediation |
| Cold spots on walls/ceilings | Leaking roof or poor insulation | Add insulation or repair leak |
2. Choosing the Right Roofing Specialist in Singapore
| Criterion | What to look for | How to verify |
|---|---|---|
| Licensing & Certification | Singapore Building & Construction Authority (BCSA) or local industry bodies. | Ask for licence copy, check BCSA website. |
| Specialist Experience | Minimum of 5–7 years doing both waterproofing and structural repairs. | Portfolio, case studies, ask for references. |
| Material Knowledge | Familiar with local climate‑resistant materials (e.g., EPDM, TPO, bitumen, concrete overlays). | Discuss preferred products; ask why. |
| Warranty & Guarantees | Clear workmanship and material warranties (at least 2‑5 years). | Get in writing, check terms. |
| Transparent Pricing | Itemised quotes, no hidden fees. | Compare 3‑5 quotes, watch for “price too good to be true.” |
| After‑care & Maintenance Plan | Scheduled inspections, maintenance packages. | Verify service contract. |
| Reputation | Positive online reviews, testimonials, and local industry awards. | Search Google, Facebook, and request references. |
Quick Interview Checklist

- Do you provide a post‑work inspection?
3. Best Waterproofing Materials for Singapore’s Climate
| Material | Key Properties | Ideal Usage | Rough Cost (per m²) |
|---|---|---|---|
| EPDM (Ethylene Propylene Diene Monomer) | Flexible, UV‑stable, excellent heat tolerance. | Flat roofs, shingle backs. | SGD 20–35 |
| TPO (Thermoplastic Polyolefin) | Heat‑reflective, recyclable, good UV resistance. | Commercial flat roofs. | SGD 25–40 |
| PVC (Polyvinyl Chloride) | Durable, easy to install, handles thermal expansion. | Flat to slightly pitched roofs. | SGD 22–38 |
| Bitumen Membranes (TPO‑Bitumen Hybrid) | Combines bitumen strength with TPO flexibility. | Heavy‑traffic commercial roofs. | SGD 30–45 |
| High‑Performance Concrete Overlay (e.g., concrete‑based waterproofing) | Strong, fire‑resistant, can levelling. | Flat roofs with structural concrete decks. | SGD 40–60 |
| Roofing Cement/Sealant (e.g., Sika‑Cement) | Excellent for patching and sealing cracks. | Spot repairs, seams, flashings. | SGD 15–25 |
Tip: In Singapore, the humidity and sudden rainstorms mean you need a membrane that can handle thermal expansion and UV degradation. EPDM and TPO are the most popular for this reason. Choose the best roofing contractors
4. Common Concrete Repair Methods
| Repair Type | When to Use | Typical Process |
|---|---|---|
| Concrete patching | Small cracks (< 5 mm) | Clean, apply epoxy or polyurethane patch, cure. |
| Spalling repair | Surface spalling from water ingress | Remove spalled area, apply surface‑level concrete overlay. |
| Re‑decking | Major structural loss | Remove damaged deck, install new reinforced concrete panel. |
| Overlay coating | Preventive maintenance | Apply waterproof concrete overlay (e.g., cementitious sealant). |
5. The Bottom Line
- Inspect promptly – the earlier you catch water leakage, the cheaper the repair.
- Pick a specialist who is fully licensed, has a proven track record, and uses the right materials for Singapore’s climate.
- Choose the right material – EPDM and TPO are generally the go‑to membranes; concrete overlays work best for flat, concrete decks.
- Plan for ongoing maintenance – regular roof inspections (at least twice a year) can save thousands in future repairs.
