When it comes to roofing, shingles often get the spotlight, but the underlayment beneath them plays a critical role in protecting your home. Especially in Kerala’s monsoon-prone regions, proper underlayment is essential for preventing water damage and extending the life of your roof.
What Is Roofing Underlayment?
Roofing underlayment is a protective layer installed between the roof deck and the shingles. It serves as a secondary barrier against water, wind, and other elements that can compromise the roof’s integrity.
Key Functions of Underlayment
Waterproofing: Prevents water from seeping into the roof deck during heavy rains or if shingles are damaged.
Protection from Wind-Driven Rain: Acts as a barrier in high-wind conditions, reducing the risk of leaks.
Temperature Regulation: Provides insulation support, helping maintain interior comfort and protecting shingles from thermal stress.
Types of Underlayment
Felt Underlayment: Traditional, cost-effective option, usually made of asphalt-saturated material.
Synthetic Underlayment: More durable, lightweight, and resistant to tearing; ideal for areas with high rainfall.
Rubberized Asphalt Underlayment: Self-sealing properties, excellent for leak-prone areas like valleys and roof edges.
How Underlayment Works With Shingles
High-quality shingles such as:
…are only as effective as the underlayment beneath them. A strong underlayment ensures that even if a shingle is damaged or displaced by wind, water penetration is minimized.
Installation Tips
Proper Overlap: Ensure underlayment sheets overlap to prevent water seepage.
Secure Fastening: Avoid wrinkles and gaps that can compromise waterproofing.
Use With Roof Accessories: Valleys, ridge lines, and roof edges benefit from additional underlayment protection. Check Scaffs India Accessory Products for compatible solutions.
