NEW CONCERNS HAVE BEEN RAISED ABOUT ROOF VENTING OR THE LACK THEREOF. THERE ARE SOME HOMES THAT DO NOT HAVE THE REQUIRED HIGH SPACE ROOF VENTING AT ALL. HOMES THAT HAVE EXISTING ROOF VENTS, WERE NOT DISTRIBUTED UNIFORMLY ON OPPOSITE SIDES OF THE BUILDING AS REQUIRED BY CODE. OUR ROOF VENTING IS NOT IN COMPLIANCE WITH THE BUILDING CODE BECAUSE THEY LINED UP 5 ROOF VENTS ALL ON ONE SIDE OF THE ROOF WHEN THEY SHOULD HAVE DISTRIBUTED THEM EVENLY WITH 3 ON EACH SIDE. IT IS KNOWN THAT SIGNIFICANT ROOF DAMAGE CAN OCCUR SUCH AS WOOD DECAY, BUCKLING ROOF SHEATHING AND REDUCED LIFE OF ASPHALT SHINGLES AMONG OTHER PROBLEMS DUE TO INADEQUATE VENTING. THE BUILDING CODE FOLLOWS:

Section 9.19. Roof Spaces

9.19.1.1. Required Venting
(1) Except where it can be shown to be unnecessary, where insulation is installed between a ceiling and the underside of the roof sheathing, a space shall be provided between the insulation and the sheathing, and vents shall be installed to permit the movement of air from the space to the exterior.

9.19.1.2. Vent Requirements
(1) Except as provided in Sentence (2), the unobstructed vent area shall be not less than 1/300 of the insulated ceiling area.
(2) Where the roof slope is less than 1 in 6 or in roofs that are constructed with roof joists, the unobstructed vent area shall be not less than 1/150 of the insulated ceiling area.
(3) Required vents are permitted to be roof type, eave type, gable-end type or any combination of them, and shall be distributed,
(a) uniformly on opposite sides of the building ,
(b) with not less than 25% of the required openings located at the top of the space, and
(c) with not less than 25% of the required openings located at the bottom of the space.
(4) Except where each roof joist space referred to in Sentence (2) is separately vented, roof joist spaces shall be interconnected by installing purlins not less than 38 mm by 38 mm on the top of the roof joists.
(5) Vents shall comply with CAN3-A93-M, "Natural Airflow Ventilators for Buildings".

FIRST VIEW HOMEOWNERS SHOULD CHECK OR HAVE THE CITY INSPECTORS INSPECT THEIR ROOF VENTING FOR COMPLIANCE OF THE APPROPRIATE SECTIONS OF THE CODE,

UNFORTUNATELY, THE TRUE NUMBER OF BUILDING CODE VIOLATIONS CAN NOT BE DETERMINED AFTER CONSTRUCTION IS COMPLETED AND THING ARE COVERED. WE EXPERIENCED NEARLY 30 BUILDING CODE INFRACTIONS WE ARE AWARE OF IN OUR HOME. YOU HAVE TO CONSIDER THAT IF A BUILDER IS WILLING TO ALLOW ANY BUILDING CODE VIOLATIONS, THEY SHOULD NOT BE TRUSTED BY ANYONE TO BUILD THEIR HOME.

IT APPEARS THESE DAYS THAT THE HOMEOWNER HAS TO BE WELL VERSED ON THE BUILDING CODE BECAUSE THE BUILDERS APPARENTLY AREN'T AND YOU DEFINITELY CAN'T RELY ON THE BUILDING DEPARTMENT IN BARRIE TO PROTECT YOUR INTERESTS IN WHAT IS FOR MOST PEOPLE, THE LARGEST INVESTMENT OF THEIR LIVES.
