Ice and rain protective underlayment.

Ice damming is a common cause of winter roof leaks. Temperature differential (inside to outside) and improper ventilation or insulation often cause snow to melt and run down to the roof edge where it collects and refreezes. The ice mass then traps water behind it that backs up under shingles and penetrates the deck, resulting in interior damage. Moisture Guard Plus creates a barrier that helps prevent water from penetrating the roof deck and coming into your home.

Shingles alone aren't always enough.

Tile. Shake. Slate. Asphalt. No roofing material is completely immune to the ravages of cold, wet weather. Ice dams caused by excessive snow, fluctuating temperatures, and improper insulation and ventilation systems can trap water in vulnerable areas and allow it to back up beneath your shingles. Powerful sheets of windblown rain can force their way under roofing as well. Without a waterproof barrier over your deck, moisture can penetrate the best roofing—and create costly damage to your home's interior.

Moisture Guard Plus: helping your roof withstand nature's worst.

Moisture Guard Plus provides an extra layer of waterproofing protection you can use to help prevent damage from ice damming and windblown rain. The self-adhering modified-bitumen underlayment creates a watertight barrier by sealing to the deck and around nails to provide continuous protection year after year. You can use it to help protect the entire deck of a properly-ventilated roof or just in problem areas where water collects or drainage is slow. And since it can go under any roofing material from asphalt shingles to tile, you can enjoy maximum roofing protection with the architectural look you want.

• Use Moisture Guard Plus and TAMKO shingles together over the entire deck with proper ventilation for maximum roofing protection
• Extra roofing protection for vulnerable areas. Use on valleys, eaves, flashings, hips, ridges, rakes, and around dormers and skylights
• Self-adhesive backing seals to the deck. SBS-modified asphalt coating helps seal around nails for a watertight finish
• Split-plastic release film eases installation and handling
• Can be used in new construction or in reroofing requiring a complete tear-off
• Helps extend the life of your roof
• Fiberglass mat is stronger and provides better tear resistance than saturated felt
• Easy to install
• Nonskid surface for better traction and safer application 
• Provides extra protection under most types of roofing including tile, wood shake, asphalt, slate or composite shingles. Not recommended for use under metal roofing. Use TAMKO TW Metal and Tile Underlayment or TW Underlayment under metal roofing applications.
