How it works

Warmer air in the attic rises to the ridge and flows out through Roof Saver® ridge vent. Soffit vents at the eaves allow fresh, outdoor air into the attic. Removal of hot, moist air from the attic reduces cooling costs and deters the growth of mold.

Protecting against cold weather

Roof Saver offers a ventilation approach aimed at limiting attic moisture and heat, thus preventing mold and mildew by moving damp air out before damage develops. The benefits extend beyond warm weather performance.

In colder climates, proper ventilation reduces moisture condensation that can accumulate when warm interior air meets cold roof surfaces, helping prevent mold, wood rot and ice-related damage. The system is also designed to resist wind-driven rain infiltration, an important consideration during winter storms.

A poorly ventilated attic means

1. Increased moisture condensation: Prime condition for the growth of molds and fungal allergens

2. Less effective insulation due to moisture: Higher heating bills

3.Excessive heat build-up: Higher cooling bills

4. Shorter lifespan for the roof: Long-term structural degradation of the attic structure

Save your attic from poor ventilation.

Roof Saver solution

Avoid mold and mildew growth by ventilating the attic. A balanced system of soffit vents beneath the eaves and a continuous ridge vent allows overheated and moisture laden air out and fresh air in. Relief of excess heat makes your home more comfortable and saves on cooling costs. Moist air must be allowed to exit the attic to avoid growth of mold and mildew. Roof Saver is nearly invisible when installed on your roof. You’ll appreciate the superior ventilation features and cosmetically pleasing appearance for your home. Roof Saver rolled ridge vent is offering homeowners nationwide a means of promoting safe, clean and environmentally responsible venting options for the attic.

Installation

• Remove ridge cap shingles along entire length of roof.
• Measure 1” from ridge peak on each side of ridge. For ridge board construction measure 1 3⁄4” on each side of ridge.
  • Snap chalk line along entire length of ridge.
  • Cut opening in sheathing along ridge. DO NOT CUT through roof trusses or ridge board.
  • Remove sheathing to create slot.
  • Leave a minimum of 12” of sheathing closed at each end of ridge.
• Tack one end of Roof Saver ridge vent, with netting side down, over the slot to hold in place at one end of the ridge. Unroll entire length of vent, pull to remove sags and tack in place so vent is snug and centered over slot. If more than one piece of Roof Saver® is needed, simply butt the multiple pieces together and tack in place with a nail.
• Install ridge cap shingles directly over Roof Saver. Use galvanized roofing nails included in package to secure in place. When properly installed, Roof Saver fills the 3⁄4” space between the underside of the cap shingle and the top surface of the roof shingles. Do NOT drive nails through shingle.
