Frequently Asked Questions

What is the purpose of waterproofing in a roofing system?

Waterproofing protects vulnerable areas of the roof — such as eaves, valleys, and penetrations — from leaks and moisture damage. It acts as a secondary barrier under shingles to help ensure long-term roof performance.

What is the difference between underlayment and waterproofing?

Underlayments cover the full roof deck to provide a general layer of protection, while waterproofing membranes are specialized products designed for areas most prone to leaks and water accumulation.

Can TAMKO® waterproofing be used under all roof types?

Yes. TAMKO® waterproofing products are compatible with asphalt shingles, metal, tile, and other common roofing materials.

Where should TW Flashing be installed?

TW Flashing is recommended around chimneys, skylights, vents, and roof valleys — anywhere water runoff may concentrate or penetrate.

Do TAMKO® waterproofing products come with a warranty?

Yes. TAMKO® waterproofing products may be covered under TAMKO’s Limited Warranty. See tamko.com/limitedwarranties for complete details.
