Ventilation

Ventilation

Ventilation consists of both air intake [soffit vents] and exhaust air [roof vents]. Without efficient ventilation the attic will be unbearably hot in the summer, reducing the life of your shingles. Moisture in the attic can damage the roof deck and contribute to wood rot and mildew. A combination of insufficient venting and insulation can produce ice dams and interior water damage. Insufficient ventilation can also negate your shingle warranties.

A custom calculation will determine the most efficient roof ventilation system.

Insulation Shingled Roof

• Hidden ridge vent/exhaust

  

  Hidden ridge vent/exhaust

  An efficient, active vent that exhausts a high volume of airflow and gives a clean look to the roof lines.

• Maximum Vents/exhaust

  

  Maximum Vents/exhaust

  For roofs with insufficient ridge length the Maximum vent clears up to 1200sq.ft. of attic space and captures wind flow from any direction. The design prevents snow and water infiltration and a wire mesh protects against rodents and birds.

• Static Vents/exhaust

  

  Static Vents/exhaust

  Used on smaller attics with clear spans, our static vents allow 80 sq.ins. of exhaust air meaning fewer vents on the roof.

• Soffit Venting/intake

  

  Soffit Venting/ intake

  Soffit vents should be checked to ensure there is a clear passage of air to the attic and the soffits are not covered by insulation or soffit board. Let It Rain may remove aluminum soffit, cut holes in the board and install baffles to ensure intake ventilation.

• The Edge Vent/intake

  

  The Edge Vent/intake

  Used where there is no soffit and is hidden at the eaves for a clean looking finish. Care should be taken to ensure this vent is not covered if further insulation is added.

• Slant Back Vents/intake

  

  Slant Back Vents/intake

  Used where it is not possible to install soffit venting. These vents are installed above the insulation line and evenly spaced around the attic.
