When investing in a premium roofing system, most homeowners focus on shingle style, colour, and durability. However, one detail that can make or break your shingle warranty is the underlayment—the layer beneath the shingles that acts as an extra barrier against water, heat, and wind. At Scaffs India, we’ve seen many cases where improper underlayment selection has compromised warranty claims.
Why Underlayment Matters in Warranty Terms
Shingle manufacturers, whether for Premium Designer Roofing Shingles, Architectural Roofing Shingles, or Asphalt 3-Tab Roofing Shingles, usually specify exact underlayment types in their warranty documents. Using a non-approved material or skipping underlayment entirely can void your warranty—even if your shingles were installed perfectly.
Common Underlayment Types
Felt Paper – Traditional option, still acceptable for many warranties.
Synthetic Underlayment – Stronger, lighter, and highly resistant to tearing.
Ice and Water Shield – Required in cold climates to protect against ice dams.
How Incorrect Underlayment Voids Warranties
Manufacturers set underlayment requirements for specific reasons:
Water Resistance – Without a proper underlayment, water penetration during storms can be blamed on installation, not the shingles.
Thermal Protection – Some shingles, especially Dynasty Roofing Shingles, require heat-resistant underlayment to maintain adhesion and granule integrity.
Wind Uplift Resistance – Advanced products like Armourshake Roofing Shingles may specify premium underlayment to achieve maximum wind warranty ratings.
If your installer ignores these specifications, warranty inspectors can deny coverage.
Best Practices for Warranty Compliance
Follow Manufacturer’s Recommendations – Always refer to the shingle brand’s technical documents.
Use Approved Accessories – Pair your shingles with Scaffs India accessory products to meet warranty requirements.
Document Installation – Keep records of underlayment type, brand, and lot number.
Hire Certified Installers – Professional installation ensures your warranty remains intact.
