Protect your Roof From Premature
Deterioration By Providing Effective Attic Ventilation.

Effective attic ventilation is critical for a long lasting roof!
A properly balanced attic ventilation system will help to remove excess heat
and moisture to protect your roof from premature deterioration; prevent roof rot
in your attic or roof deck; minimize peeling and extend the life of exterior and interior paint;
safeguard your attic possessions against mildew damage; guard against
ice damming in harsh winter climates and may even reduce excessive heating
and air conditioning costs.

the best and safest choice for protecting your most valuable asset. The Weather Stopper Roofing System has also earned the Good Housekeeping Seal which means that Good Housekeeping

Including Timberline, the #1 selling architectural shingles in America - your safest choice in roofing.
From the name homeowners have trusted since 1886!
4. Effective Attic Ventilation
Cobra (roll or hard plastic) and Master Flow Ventilation Products help protect against premature roof deterioration (when used in a properly balanced ventilation system.)
5. Distinctive Ridge Cap Shingles
Timbertex and TimberRidge Ridge Cap Shingles enhance the appearance of your home while guarding against leaks at the ridge line.

Calculating your Ventilation requirements
Balanced ventilation requires 1 square foot of ventilation for every 300 square feet of attic floor space.

1. Calculate the total square footage of the attic floor area (round up to the highest number). This number will determine the minimum total linear feet of Cobra Sof-Edge air intake vent that is needed.
2. Find the appropriate amount of Cobra Sof-Edge air intake vent and minimum exhaust ventilation that corresponds to the total attic square footage.
