At in Singapore, our team has consistently provided homeowners with critical, fact-driven roofing information for over 30 years, helping them navigate the often sceptical roofing industry. Here, we offer a comprehensive guide to understanding and managing your roof inspections effectively.

What is a Roof Inspection?

A roof inspection involves a detailed evaluation of your roof’s current condition to determine if it’s performing as expected. The purpose of a roof inspection is multifaceted, aimed at ensuring the longevity and functionality of one of the most critical components of your home. Typically, homeowners opt for inspections to assess the remaining lifespan of their roofing system, determine the necessity for a replacement, or to identify and repair leaks.

Why Roof Inspections are Crucial

Roof inspections are essential for several reasons beyond the obvious leak checks. They can be particularly critical before selling or purchasing a home, after significant weather events that could have caused damage, and as part of routine home maintenance. Regular inspections can detect minor issues before they escalate into significant problems, potentially saving homeowners substantial repair costs.

How Does a Roofer Inspect a Roof?

Our roofing specialists conduct comprehensive inspections by examining several key elements of your roof:

1. Number of Layers:

  • Regulation: Singapore’s building codes allow a maximum of two layers of roofing material for fire safety and structural integrity reasons.
  • Procedure: Our inspectors use calipers and depth gauges to measure the thickness of existing roofing layers. Removing excess layers during a replacement can increase labor costs by approximately 20%.

2. Drip Edge:

  • Importance: A drip edge is essential for directing water away from the fascia and underlying roofing structures.
  • Compliance: Installation of a drip edge is mandated under the Singapore Standard Code of Practice for Roofing.
  • Observation: Inspections involve checking for corrosion or improper fitting, with 15% of roof leak issues stemming from inadequate drip edges.

3. Roof Decking:

  • Material Analysis: Common materials include plywood and oriented strand board (OSB); both are inspected for moisture content using a wood moisture meter, with safe levels typically below 20%.
  • Damage Indicator: A spongy feel underfoot suggests a moisture content over 25%, often necessitating replacement of affected sections, which can cost SGD 500 to SGD 1,000 per 10 square meters.

4. Roofing Material:

  • Durability Assessment: Typical materials like asphalt shingles, clay tiles, and metal panels are assessed. Asphalt shingles, for example, should have a granule loss of less than 20% to be considered in good condition.
  • Lifespan Statistics: Asphalt shingles generally last 15-20 years in Singapore’s climate, whereas metal and tile can last over 30 years with proper maintenance.

5. Roof Penetrations and Flashing:

  • Inspection Focus: Areas around chimneys, vent stacks, and skylights are checked for seal integrity.
  • Cost Impact: Repairing or replacing flashing involves costs ranging from SGD 200 to SGD 750, depending on material and extent of damage.

6. Gutters and Downspouts:

  • Function Check: Inspectors assess for clogs, alignment, and proper slope using levels and measuring tapes. Incorrect gutter slope (less than the standard 1/4 inch per 10 feet) can lead to standing water.
  • Repair Costs: Cleaning or repairing gutters typically costs between SGD 100 and SGD 300, depending on the length and condition of the gutter system.

7. Attic Space:

  • Ventilation Check: Adequate attic ventilation is crucial to prevent heat and moisture buildup that can shorten roof lifespan. Ventilation rates should be at least 1:300 (roof area to vent area).
  • Moisture and Insulation: Moisture meters and thermal cameras are used to detect insulation effectiveness and any moisture intrusion, which could indicate leaks.

Duration and Frequency of Inspections

Depending on the size, complexity, and accessibility of the roof, an inspection can take between 1 to 2 hours. In Singapore, where environmental factors such as high humidity and frequent rainfall can significantly affect roof materials, it is advisable to conduct inspections bi-annually. This regular schedule helps maintain your roof in optimal condition, adapting to seasonal changes and addressing any emergent issues promptly.

Cost of Roof Inspections

The cost of a roof inspection at ranges from SGD 150 to SGD 500, depending on the complexity of the roof and the specific requirements of the inspection. This fee includes a comprehensive report detailing the condition of the roof and any recommendations for maintenance or repair.
