Roofing Process

Why do we only offer the asphalt shingle roofing system?

Firstly, we have found that specializing in only one service makes us experts in providing that service. We have gotten this installation process down to a science. Secondly, we believe that this roofing system is superior to any other system because of 3 main points:

  1. Durability - The system is hermetically water-proofed, preventing any seepage leading to water damage.
  2. Light-weight Material - Lesser load on the roof structure, ensuring structural integrity stays intact over time.
  3. Cost-effectiveness - Provides quality protection without burning a hole in your wallet! 

Here are the practices we follow during a shingle roof installation/replacement:

Roof Deck Preparation

In the case of re-roofing, old asphalt shingles and any old underlayment are to be removed and discarded appropriately. The deck gets a thorough inspection for any rotten spots and repaired using same thickness wood. After that we ensure the deck is smooth, firm and dry before application of the roofing starts. 

METAL DRIP-EDGE: For efficient water shedding, a metal drip edge is installed at the edge of the roof over eaves. 


Once the roof deck has been prepared, an inspection is done to see that it contains enough vent holes. Proper ventilation is important, in order to remove the excess attic heat during the summer and excess water vapor during the winter. Alberta building codes specifications are followed accordingly. We provide and install a range of venting solutions, includding goose neck vents, attic vents, phoenix vents, ridge venting etc. For maximum durability and higher performance we recommend Ventilation Maximum air vents.

Ice and Water Protection

For protection against ice and water daming, eaves protection or ice and water membrane ought to be installed for at least 3' from the eave. Areas with severe icing and frequent freeze/thaw cycles, 5' from the eave or two rows of the membrane are recommended. A layer of the waterproofing membrane is used as underlayment in the valleys before the valley metal installation.


The building code states that for fiberglass shingles below 8/12 slope, 1 ply of an approved underlayment parallel to eaves over the portion of roof deck not already covered by ice and water membrane. Instead we cover the entire roof with underlayment, except the areas with ice and water membrane. We provide and install a range of synthetic underlayments. 


Most roofs have joints and breaks such as valleys, dormers, chimneys, vents etc.. Care must be taken that flashings are waterproof to avoid leakage at these danger points.


VALLEY METAL FLASHING: For longer roof performance, metal valley flashing is crucial. After the ice and water membrane is applied, valley metal is nailed on the edges and tight to the deck. When the shingles are applied, the valley metal can be covered with shingles, called a closed valley, or cement applied on the edges and the shingles cut in a straight line parallel to the valley. 


CHIMNEY FLASHING: The most common chimney flashing is made of sheet metal, and is the only type we install. Once the roof deck is prepared, we know if the chimney needs a partial or full reflashing. We will inform you as soon as something like this is noticed and options will be discussed along with anything else that might be concerning. 


STEP FLASHINGS: Anywhere the roof meets a house wall it is an dangerous area for possible leaks if not done right. There need to be a step flashing for every layer of shingle long enough to overlap over each other by at least 2''. The shingles overlapping the flashing have to be cut so they fit perfect next to the flashing to prevent any leaks. 

Shingle Installation

Out of all the phases of the roofing process, shingle installation is the one that can make or break the end result. Listed below are the steps we undertake to ensure the shingle system meets and exceeds manufacturer standards of installation. 


Even distribution along nailing strip of shingles with a minimum of 4 nails properly driven. All nails are galvanized and corrosion-resistant.


Caution must be exercised to ensure that end joints are no closer than 2" from fastener in the shingle below and that side laps are no less than 4" in succeeding courses.


Shingles are precision cut around vents, flashings, valleys and side edges of roof. Extra cement is applied along the flashings within 3" of the edge of the shingles.

Ridge cap shingles

Ridge cap shingles are applied beginning at the bottom of the hip or the ridge opposite the direction of the prevailing winds. 4 nails per ridge cap shingle are used, 2 on each side, 1" from the edge so succeeding shingles conceal nail heads.

There are 2 kinds of ridge cap shingles, namely, regular and high profile ridge cap shingles.


Consists of single layer cut-up strip shingles.


Ready made, double layered shingles that ensures multi-layer protection at the highest stress areas of the roof (the hips and ridges). Accentuates the natural beauty of your new shingle roof providing the look of thick wood shakes. 

Fastening and Clean-up


The bottom of vents, chimneys, skylights and wall flashings are not to be covered by shingles to prevent ice and water damming. The fasteners (nails and screws) holding them down are cemented with high-grade roofing silicone. 


The last important step of a properly installed roof is the clean-up. All debris is removed from site and we use a magnetic roller to remove any and all loose nails and staples.
