Eco Metal Roof Installation VS Traditional Installation 
​

LIFETIME ENERGY SAVINGS  OR EVER INCREASING ENERGY COSTS?

There are essentially 2 TYPES OF METAL ROOFING INSTALLATION. 

1. Double  Strapped or Batten Mounted Installation with ASV (Above Sheathing Ventilation)

Metal roof systems  mechanically attached over wooden strapping systems optimize attic ventilation by means of DUAL RIDGE VENTILATION . Heated air beneath the metal roof panels is vented out of the roof via a dual ridge ventilation system which draws fresh cool air into your roof attic in Summer.  This is known as ABOVE SHEATHING VENTILATION and it is 50% more energy efficient than deck mounted roofing. All LONDON ECO ROOFS are mounted on battens and feature DUAL RIDGE VENTILATION that saves money on energy.

2. Sheathing or Deck Mounted Installation with External Stack Vents

Traditional asphalt shingles and sheathing mounted metal roofing systems transfer heat energy from the sun directly in to your attic . This drives up your Summer cooling costs and means air conditioners must work harder to keep your home cool.

In Winter, Eco roofs roofs built on double strapping  save on Winter heating energy.  Because ridge vents are connected to the double strapped sheathing ventilation system , Eco Roof has no external roof vents protruding from your roof. . Eco Roof's  ridge vent is concealed within the roof,  unlike traditional  Maxi Stack Vents that protrude from your roof to create maximum air turbulence in  both Summer and Winter. This attic air turbulence disturbs the heat flux layer in your roof  and drives up energy costs. A dual ridge vented roof with double strapping and ASV provides for more stable air mass in the attic. Less air turbulence in your attic means that that the  heat flux layer on top of your insulation provides better insulation due to a more stable attic air mass.  

Sheathing or deck mounted metal roofing  by comparison generally require standard roof ventilation - typically protruding vents like the Maxi and Whirlybird vents designed to maximize attic air turbulence.


ENERGY FACTS TO CONSIDER DIRECTLY RELATED TO THE TYPE OF ROOF SYSTEM YOU CHOOSE FOR YOUR HOME
​

  •  ALMOST 60% of ENERGY GAINED AND LOST  FROM A HOMES BUILDING ENVELOPE TAKES PLACE THROUGH ITS ROOF
  • UP TO 45 % OF  ALL RESIDENTIAL ENERGY COSTS ARE SPENT ON SUMMER COOLING
  • AVERAGE ONTARIO HOME AIR CONDITIONING ENERGY COST -  $650 -$800 /YR 
  • WITH ECO ROOF  YOU GET A 45% REDUCTION IN HEAT TRANSFER IN TO YOUR ATTIC IN SUMMER ,  YOU ENJOY BOTH SUMMER & WINTER HEATING SAVINGS
  • THE AVG. ENERGY SAVINGS WITH ECO  METAL ROOFS -  SAVE $250- $400 /YR ON SUMMER COOLING PLUS SAVE $150-$250/YR ON WINTER HEATING*
  • OVER 15 YEARS ( TYPICAL LIFE EXPECTANCY OF AN ASPHALT SHINGLE ROOF ) HOMEOWNERS CAN SAVE $6000 OR MORE IN ANNUAL ENERGY COSTS
     
      ( Ref *1 & *2 )


    *  ENERGY SAVING ASSUMPTIONS
    *1  Based on  avg. R20 home with 1500 sq.ft.  floor area and typical 2000  sq. ft. roof area including eave overhangs with 18 inch soffits
    * 2 Using 1200 BTU  or higher HVAC system for Summer cooling 8 hours /day for 5 months /year, and  intermittent day/night Winter heating ( to 20C ) for 6 months a year
