We supply and install many sloped roofing products: Asphalt Shingles, Composite Roofing Materials and Metal Roofing. We also offer 2 ply membrane systems for single family residential applications. Roofing materials are available in 1000’s of designs and colours from a number of North American manufacturer’s.

We are factory certified installers through IKO, GAF, BP Canada and CertainTeed.  What this means for our clients is that we have met the requirements of these manufacturers in product knowledge, proper installation techniques and business ethics.  We are therefore able to offer factory backed extended material and labour warranties, in some cases for up to 50 years, against manufacturing and/or installation deficiencies.

Today’s roofing materials have designs that are amazing.  Between the material properties and the visual appearance there is a roofing material that will meet your need for great curb appeal and performance.  With weather damage of concern roofing manufacturers have risen to the occasion and offer options for both high wind and impact resistance.  Some of these products may even qualify for a reduction in insurance premiums.

Basic Guide to How We Install a Typical Roofing System:

When we replace a roof the first step is to remove the existing roofing materials.  Best practice is to remove the existing roofing materials, while some may say it is OK to go over the existing materials we always remove them as this provides a superior surface to maintain the integrity of the new roofing materials being installed.  Once the materials are removed and disposed of we clean the roof deck of debris and protrusions.  The roof deck is checked for integrity and all damaged roof decking is replaced as needed.

The next step is the installation of eave protection and underlayment on the roof surface.  The Alberta Building Code (ABC) specifies the minimum requirements of what materials can be used as well as where they need to be installed.  While not necessarily required by the ABC good roofing contractors will always recommend the installation of a quality underlayment as additional protection against wind driven rain and blow-offs.  Eave protection can take the form of a non-self-adhered SBS (a special type of modified asphalt used to construct the material) “Base Sheet” or fully-self-adhered SBS “Ice & Water” membrane.  The self-adhered products are also self healing meaning they seal around nail penetrations to prevent leakage, they also provide superior protection against potential “Ice Dams”.  Once the eave protection has been installed the underlayment will be install to lap over the eave protection and cover the entirety of the balance of the roof surface.  The most common type of underlayment is known as 15# (“15 pound”) Felt Paper.  This is a cellulose base material impregnated with asphalt.  Synthetic underlayments are a more recent addition for roofing systems.  These materials are generally made from synthetic woven fibers with properties from non-breathable to breathable, slip resistant surface and high tensile strength.  When it comes to underlayments we recommend the use of a breathable product to ensure moisture is not trapped which may lead to wood and shingle damage.  Felt Paper is considered a breathable underlayment.  

Next is the installation of the edging details.  This can include the use of drip edge flashings.  These can be installed at the eaves and rake ends of the roof surface.  These edge flashings promote the draining of water away from the building and reduce the opportunity of the drain water “wicking” back onto building preventing damage.  

Special “Starter Strip” shingles are installed along the outer edges of the roof.  The come with a factory installed adhesive to seal to the roofing material.  The aids in the prevention of wind damage by bonding to the shingles.  Most shingle manufacturers require the use of starter shingles in order to qualify for wind damage protection.  

Now that the foundation of your roof has been installed it time to get the roofing material of your choice installed.  

While the above noted procedures are the most common there are variations depending on what roofing material you choose.  In any case the methods followed are to ensure an excellent looking and superior performing roofing system.

Roofing materials are available in a wide variety of styles, shapes and colours.   They can be made of asphalt, wood, cement,  ceramic, and composite (synthetic) product.  Each has their own distinct characteristics when it comes to looks and performance.   Some important features are fire ratings, impact resistance, and curb appeal.

The most common is the asphalt shingle.   Asphalt shingles are popular because they provide long term protection at a relatively low cost.  The colours and designs available offer an almost unlimited palette to suit the look you are looking for.  When installed according to manufacturers directions they have the highest fire rating, UL Class A.  

Popular Asphalt Roofing Materials:

This is an example of an “Architectural Shingle” also known as a “Laminate Shingle”.  It is constructed of a base layer with a cut-out layer laminated to the base layer to provide a dimensional appearance.  When installed the overall look has a random pattern in an attempt to mimic the look of a cedar shingle type roof.

This is an example of a “Designer Shingle”.  These are generally high end super thick and durable shingles.  Most carry a UL Class 4 impact rating (IR) recognized as the highest standard against hail damage resistance for asphalt shingles.

Starter Shingles

These shingles are installed along the eaves and up the gable ends.  They provide coverage where the first course of shingles are placed together, the joints, so that at the joints there is an underlying course of material.  These won’t be seen once the first course of asphalt shingles are installed.  What is important about these shingles is that they have a factory installed sealing strip along the outer edge.  This seal strip bonds to the shingles placed over these shingles.  This adhesion is critical to maintain a strong resistance to wind uplift .  The eaves and gable ends are considered key in the fight against wind uplift.  In general if the shingles are not sealed along the edges a failure will result in further damage to the field shingles.  

Eave & Valley Protection

The Alberta Building Code 2014 (ABC) requires heated eaves of specific slopes to have an eave protector installed.  An eave protector is basically a non-breathable, impermeable membrane.  It can be either non-self-adhered or fully self-adhered.  An example of an eave protector would be IKO Deckbase 44″ or GAF Weather Watch membrane.  Where required, the eave protection needs to extend from the edge of the eave to a distance of not less than 1′ from the inner face of the wall as measured along the roof slope.  The purpose of an eave protector is to provide an additional barrier to protect against possible ice dam issues at the the most likely and critical location for their formation.  

The advantage of using a self-adhered membrane is that the membrane “heals” around nail penetrations.  While a standard non-self-adhered membrane provides adequate protection for most circumstances and weather conditions it is best practice to install a self-adhered membrane to guard against more severe and unlikely weather conditions.  We recommend that an ice & water protector also be installed in the valleys of a roof.  Here too we find an increase in ice damming to which a self-adhered membrane can provide additional protection against.

Underlayments

Over the remaining roof surface an underlayment may e installed.  Most shingle manufacturers recommend an underlayment be installed previous to the shingles being installed.  The ABC does not require that an underlayment be installed however it is best practice to install an underlayment.  This barrier can prevent infiltration of moisture into the attic from wind driven rain and provide protection in the event of wind damage.  There are many different types of underlayment available on the market today.  They can be generally broken down into two categories.  The first being a breathable type the other a non-breathable type.   Breathable underlayments will allow the diffusion of moisture through the roof system to the outside whereas a non-breathable underlayment will limit the movement of moisture and in certain circumstances trap this moisture within the roofing system which could lead to damage.
