FINISHED RIDGE VENTS WITH RIDGE SHINGLES ON TOP OF THE RIDGE VENT.
THESE ARE 3-TAB SHINGLES CUT AT TAB.

Designing A Balanced System

House Roof Ridge Venting

Air Vent ShingleVentII - Image Courtesy of Air Vent Inc.In independent tests against competitive ridge vents, Air Vent products produced the greatest amount of low pressure above the vent, which resulted in a greater ability to exhaust air from the attic. Two unique features contribute to the superior performance of Air Vent, making it the best roof ridge vent:

  1. External Wind Baffle deflects wind—even the slightest breeze—up and over the vent, creates low pressure to “pull” air out of the attic, and help prevent windblown rains and snow infiltration.
  2. Internal Weather Filter deflects rain, snow and insects to provide a more complete weather barrier. This filter is NOT treated with any oils or chemicals.

Unbaffled Ridge Vents:

  • Air problems of an unbaffled ventAn unbaffled ridge vent allows wind and elements to blow directly in through the ridge vent. Air entering the vent can create pressure in the attic which prevents air and moisture from being pulled out.
  • Wind and elements can blow directly in through the ridge vent. Air entering the vent can create pressure in the attic which prevents air and moisture from being pulled out.

The Simple Mathematics of a Balanced Ridge Ventilation System:

A balanced ventilation system is one that best employs three natural forces: air pressure, thermal effect and diffusion. For every square inch of ridge (exhaust) vent you must balance it with at least one-square inch or more of soffit (intake) vent. Most building codes define a “balanced” ventilation system as one-square foot of ventilation for every 300 square feet of attic floor space, with half the ventilation represented by intake vents and half by by exhaust vents.

Air Vent Roof Ridge VentFor an attic ventilation system to work properly, the volume of air intake must be equal to or exceed the air exhaust. With a ridge vent system, intake vents must be placed low on the roof, usually in the eaves. Years of research have proven that Air Vent ridge vents, combined with under-eave venting, are the most efficient and effective system you can install.

This balanced system provides greater airflow than any other fixed vent—and it’s the most attractive system.

BBB ACCREDITED

Posted: June 24, 2012 in Uncategorized

BBB ACCREDITED – INSURED -LICENSED – LOCAL TO DFW

THE VALLEY IS BY FAR THE WORSE PLACE TO HAVE A LEAK.  

AFTER A ROOF IS INSTALLED, IF THEY DID NOT INSTALL ICE&WATER SHIELD

SOMETIME IN THE FUTURE THIS WILL BE A PROBLEM.  

ICE AND WATER SHIELD ADHERES TO THE DECK, MAKING IT IMPOSSIBLE FOR

WATER TO MIGRATE UNDERNEATH IT.  IT IS A THICK RUBBER LIKE MATERIAL

AND IS WHAT A ROOFER SHOULD PUT IN YOUR VALLEYS.   METAL IS THE OLD WAY AND

ICE AND WATER SHIELD IS THE UP TO DATE MATERIAL TO USE.

1.         THE CONTRACTOR SHOULD BE WITH AN ACCREDITED MEMBER OF THE BBB.

2.         THE CONTRACTOR SHOULD BE LOCAL TO YOUR AREA. 

             THIS IS IMPORTANT BECAUSE OF WARRANTY WORK.

3.         THEY SHOULD BE INSURED: AND YOU SHOULD CHECK THEIR POLICY TO SEE THAT 

              IT IS UP TO DATE.

4.          THEY SHOULD SUPERVISE THEIR JOBS FOR QUALITY WORK.  THEY SHOULD NOT EXPECT

              THEIR ROOFER TO – YOU HAVE TO HAVE QUALITY CONTROL.        

5.          THEY SHOULD HAVE GOOD REFERENCES.

6.          YOU SHOULD HAVE A WRITTEN ESTIMATE.

I WILL BE GLAD TO ANSWER ANY ROOFING QUESTIONS YOU MAY HAVE.  YOUR ROOF IS THE MOST IMPORTANT PART OF YOUR HOME.

IT PROTECTS YOU AND ALL OF YOUR BELONGINGS.  YOU MIGHT SAY IT HAS YOU COVERED AND HAS YOUR BACK.
