When you're hiring a roofing contractor, you'll see a lot of claims — 'experienced,' 'licensed,' 'trusted.' But one credential actually carries weight: CertainTeed ShingleMaster Certified.

What Is CertainTeed ShingleMaster Certification? CertainTeed is one of North America's leading manufacturers of roofing materials. Their ShingleMaster program recognizes contractors who have demonstrated a high level of product knowledge, craftsmanship standards, and ongoing training.

To earn ShingleMaster status, a contractor must:

• Have installers pass CertainTeed's rigorous knowledge assessment
• Demonstrate consistent adherence to installation best practices
• Maintain an active relationship with CertainTeed

Why Does This Matter for You? The biggest reason: your warranty.

When a non-certified contractor installs CertainTeed shingles, you typically receive the standard manufacturer's warranty. But when a ShingleMaster-certified contractor does the work, you're eligible for SureStart PLUS — CertainTeed's enhanced warranty that provides non-prorated coverage for up to 50 years.

That's a massive difference in protection.

What Else Do You Get?

• Peace of mind that installers know the product inside and out
• Assurance of proper installation techniques that maximize shingle life
• A clear path to warranty claims if anything goes wrong
