The Roofing System

How can you tell if your roof needs to be replaced? Find out what should be installed by professional roofers in your roof and attic to achieve the most durability and energy efficiency through our roofing system diagram!

  • The Shingled Roof

    The Shingled Roof
    The shingles are the primary protection for a roof and are the most visible aspect of your roof. However, it is the unseen components that offer secondary protection and are often the cause of problems throughout the shingle’s life. The installation of pre-painted steel drip-edge and flashings that neither rust nor contract, full cover underlay, and the proper protection of roof penetrations require top-quality materials and superior craftsmanship to be effective in protecting your home from the extremes of the Canadian climate.
    • Drip Edge
      Drip Edge

      Drip Edge

      Custom 6 inch, pre-painted steel, seals the gap between the roof deck and fascia protecting this area against rain, snow and animal intrusion.
    • Ice and Water Shield
      Ice and Water Shield

      Ice and Water Shield

      Building code requires a layer of underlay from the eaves to a point 1foot inside the interior wall. Let It Rain installs 6 foot of ice and water shield above the eaves and also at valleys to seal these vulnerable areas at the points in the roof where snow and ice dams cause major damage.
    • Deck Armor
      Deck Armor

      Deck Armor

      Ice and snow cling to the roof during the winter months which is why, for complete protection, Let It Rain covers the complete roof with underlay. Deck Armor allows the roof to breath releasing moisture from the attic.
    • Valleys
      Valleys

      Valleys

      Pre-painted steel flashing is installed at the valleys to clear water run off and eliminate shingle damage at these areas.
    • Step Flashing
      Step Flashing

      Step Flashing

      Wherever a roof meets a wall, flashing is installed to seal the joint. On a slope a step flashing is used under a counter flashing creating a clean finish to the roof lines. Let It Rain uses a pre-painted steel flashing, rather than aluminum, for it’s strength. Steel contracts and expands less than aluminum meaning the caulking is under less strain.
    • Chimney flashing
      Chimney Flashing

      Chimney flashing

      Chimneys are surrounded with ice and water shield before the step flashing and back pan is installed. All other roof penetrations, such as plumbing stacks, are protected with ice and water shield.
    • Hip and Ridge Caps
      Hip and Ridge Caps

      Hip and Ridge Caps

      These are heavy 12 inch accessory caps installed at exterior joints in the roof and over ridge vents for a clean looking line.
    • Weather Blocker starters
      Weather Blocker starters

      Weather Blocker starters

      continuous starter strips with a properly positioned adhesive to prevent blow off.
  • 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.


    • Hidden ridge vent/exhaust
      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

      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

      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 Vent/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

      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

      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.
  • Insulation

    Insulation
    An attic upgrade reduces energy consumption and keeps attics dry preventing damage to the roof deck.Without sufficient insulation and adequate air sealing, common problems such as ice dams and interior moisture damage can occur. Warm air travels to colder spaces and when it makes contact with a cold surface it condenses and can lead to leaks inside the home. With inadequate insulation, heat is transferred from the attic to the living space in the summer and during the winter heat and moisture move from the living space to the attic.
    • Dysfunctional Attic
      Dysfunctional Attic

      Dysfunctional Attic

      A dysfunctional attic space allows heat to escape from the house, moisture to damage the roof deck and can reduce the life of the shingles. The attic should always be inspected as an essential part of a roof estimate!
    • Air sealing
      Air sealing

      Air sealing

      An attic floor penetration that is not sealed allows excessive heat and moisture into the attic space. Plumbing stack gaskets, B-vents and electrical penetrations need to be sealed.
    • Bathroom and Kitchen Fans
      Insulated Flex Hose

      Bathroom and Kitchen Fans

      Fans must be vented to the exterior of the house otherwise heat and moisture is being vented from the fan into the attic increasing heat and moisture damage. An insulated flex-hose should be connected from them to a damper vent on the roof.
    • Pot Lights
      Pot Lights

      Pot Lights

      Air sealing around pot lights to reduce heat transfer.
    • Baffles
      Baffles

      Baffles

      The soffit vents should be open and baffles installed to allow an intake of cool air from the exterior. Together with roof vents an air flow is created keeping the attic cool and dry.
    • Insulation
      Cellulose fibre insulation

      Insulation

      Top-grade Cellulose Fibre insulation is the basic ingredient for an energy efficient home. To install the insulation at the correct density it has to be installed from the attic interior and be blown into all the attic crevices. Insulation blown in from a roof vent will not be efficient.
    • Damper Vent
