FELT PAPER - #15

Asphalt-saturated #15 felt paper has been a trusted roofing underlayment for over a century, laid directly on the roof deck of sloped roofs beneath asphalt shingles, wood shakes, and tile. It acts as a secondary water barrier, shedding any moisture that gets past the primary roofing and protecting the deck during installation before the shingles go on. The asphalt saturation gives the organic felt water resistance and tear strength while still breathing to let the deck dry. Rolled out and fastened course over course, it is the standard base layer for a durable, weather-tight sloped roof.

Key Features:

• Secondary Water Barrier -- Sheds moisture that gets past the primary roofing to protect the deck.
• Asphalt-Saturated -- Saturation adds water resistance and tear strength to the felt.
• Deck Protection -- Shields the roof deck during installation before shingles go on.
• Proven Underlayment -- A trusted sloped-roof base layer for over a century.
• Breathable -- Lets the roof deck dry while resisting water intrusion.

Where to Use:

• Sloped roofs -- Underlaying asphalt shingles, wood shakes, and tile.
• Roof repair -- Replacing worn underlayment during re-roofing.
• Deck protection -- Covering a deck to keep it dry until roofing is installed.
