Understanding Wind & Fire Ratings in Shingle Codes (IBC & IRC)

Roofing in India—especially in weather-intense regions like Kerala—demands a clear understanding of safety codes. Homeowners and architects often ask:

“Are these shingles rated for strong winds?”
“Will they withstand a fire hazard from nearby structures or wildfires?”

The answers lie in shingle codes and certifications—specifically from standards like IBC (International Building Code) and IRC (International Residential Code). In this guide, Scaffs India breaks down what wind and fire ratings really mean, and how our roofing solutions meet or exceed global safety standards.

🏗️ What Are IBC & IRC Shingle Codes?

The International Building Code (IBC) applies to commercial structures, while the International Residential Code (IRC) governs homes and low-rise dwellings. Both specify:

• Minimum requirements for wind uplift resistance

• Fire classification based on how shingles respond to flame exposure

• Installation best practices and material integrity

Shingles compliant with these codes have been lab-tested for real-world threats, such as storm-driven winds and flying embers.

🌬️ Wind Ratings: What Do They Mean?

Shingles are tested under ASTM D3161 and ASTM D7158 standards. Based on the performance, they receive:

• Class A (Highest Wind Rating)
  Can withstand wind speeds up to 210 km/h (130 mph)
  👉 Ideal for storm-prone or coastal areas

• Class D or F Ratings
  Suitable for moderate to high wind zones, depending on local code requirements

✅ Scaffs India’s Architectural Shingles and Premium Designer Shingles are Class A or F rated and suitable for Kerala’s stormy monsoon conditions.

🔥 Fire Ratings: A, B, and C Class Explained

Fire ratings for roofing shingles are classified using ASTM E108 (or UL 790) fire tests. The classes are:

• Class A
  🔺 Most flame-resistant
  🔺 Resists severe fire exposure
  🔺 Won’t ignite or allow flames to spread easily
  🔺 Best for urban zones, forest-adjacent homes, and wildfire-risk areas

• Class B
  ⚠️ Moderate fire resistance

• Class C
  ❗ Only protects against light surface burning

🔥 Our 3-Tab Asphalt Shingles, along with the Tejas Borja roofing tiles, comply with Class A fire rating standards, giving Kerala homes maximum protection.

🏘️ Fire & Wind Code Compliance in India: Why It Matters

India does not yet enforce a universal shingle fire code. But international clients, resort developers, and villa owners increasingly demand code-compliant materials for:

• 🌪️ Monsoon protection

• 🔥 Fire risk zones (near factories, dry plantations, or forest edge homes)

• 🏢 Export-quality construction

• 📐 Architect-specified guidelines for luxury builds

👉 Whether you’re building mudroom cottages, wooden chalets, or A-frame designs, understanding wind/fire ratings helps you select the safest shingles available.
