Asphalt Shingles

Top Rated Asphalt Roofing in Calgary

There are a few reasons behind why we prefer asphalt roof systems. For years it was one of the only systems our Calgary roofing company would install. This was because by specializing in one service we were able to excel at it. Since starting National Star Roofing Specialists in 2003, we’ve gotten the installation process down. Our expertise allows us to get a job done efficiently and reliably.

We use asphalt shingles because we strongly believe they are superior as a roofing system. One reason we feel that way is because of the durability asphalt roof tiles provide. The system is hermetically water-proofed, preventing any seepage from leading to water damage.

Asphalt shingles are also made of a light-weight material, which leads to less load on the roof structure, ensuring the structural integrity stays intact over time. There are different kinds of asphalt shingles and applications that can be used to ensure your residential roofing system stands the test of time. Asphalt shingles are a cost-effective option that provide quality protection for your home, without burning a hole in your wallet!

At National Star, we offer a standard roof package and will work with our clients to combine different products to create a roofing solution that best fits each client’s individual needs and wants. We can discuss better options for wind and hail product applications, as well as various ice-damming and condensation applications.

Over time your roof will stop looking its best. When it does, you’ll have to decide if you need a full roof replacement or a roof repair.

In Calgary, we’re prone to hail in the summer months. With the wrong kind of roofing system in place hail can quickly ruin shingles, leading to damage on the membrane and eventually impacting the vapor seal which is essentially the last line of defense before you start to see the effects in your home.

Before it gets to that point though, there are a few things you can keep an eye out for. If you’re concerned about hail damage look for signs of cracking or granules missing from the asphalt shingles. With Chinooks come high winds, if you’re worried a broken tree branch may have hit your roof on the way down, look for missing or misshapen shingles.

Fixing a problem now can save you from damage down the road, which is why all of our roofing contractors are Haag Certified. National Star can provide a full inspection, make you aware of any damage to your system and provide a full roof repair in an efficient and timely manner.

It’s inevitable that you will need a roof replacement at some point while owning your home. When the time comes, you want a company that can deliver the highest quality materials and workmanship. We believe in educating homeowners, which is why we always take the time to walk through the process and explain what we’re doing.

Replacing your roof is an important step in protecting your investment. Our contractors are Haag Certified and can inspect your roof first, to help you determine if it’s time to repair it or replace it. By holding off, you could end up paying more in collateral costs from interior damage to your home or any concealed deterioration of the roofing structure.

A replacement, also known as reroofing, is when we strip the roof down to the frame and start fresh. Fortunately, with regular maintenance, a full roof replacement isn’t something you’ll have to deal with on a regular basis. Providing it was also installed properly in the first place. A roof replacement cost can vary based on materials and the scope of work, which is why it’s always best to call and get an estimate ahead of time.

Our Roofing Process

Top Rated Asphalt Roofing in Calgary

1) Roof Deck Preparation

Before beginning any roofing project, the deck must be prepared for the shingles and system. In the case of re-roofing, or roof repairs, old asphalt shingles and any underlayment are removed and discarded appropriately. The deck then gets a thorough inspection for rotten spots and is 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.

2) Ventilation

Once the roof deck has been prepared, an inspection is done to make sure it contains enough vent holes. Proper ventilation is important in order to remove the excess attic heat during the summer and excess water vapour during the winter. As with every part of the process, Alberta building code specifications are followed accordingly. We provide and install a range of venting solutions, including goose neck vents, attic vents, phoenix vents, ridge venting and more. For maximum durability and better performance, we recommend Ventilation Maximum air vents.

3) Ice and Water Protection

Protecting your home from ice and water damage can save you from costly repairs down the road. For protection against ice and water damning, eaves protection or the ice and water membrane ought to be installed for at least 3′ from the eave. Areas that have 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.

4) Underlayment

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

5) Flashings

Most roofs have joints and breaks such as valleys, dormers, chimneys, vents etc. When replacing a roof, or installing one on a new build, care must be taken to ensure the flashings are waterproof which will help avoid leakage at these danger points. At National Star Roofing Specialists, we use Valley Metal, Chimney and Step Flashing to ensure a leak-free roof.

6) 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 specific steps we undertake to ensure the asphalt shingle system we install meets and exceeds the manufacturer’s standards.

Even distribution along nailing strip of shingles is done, with a minimum of four nails properly driven. All the nails are galvanized and corrosion-resistant. Caution must be exercised here to ensure the 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 then applied along the flashings within 3″ of the edge of the shingles.

7) Ridge cap shingles

The next step is the ridge cap shingles. These are applied beginning at the bottom of the hip, or the ridge, in the opposite direction of the prevailing winds. Four nails are used per ridge cap shingle – two on each side – 1″ from the edge. This allows succeeding shingles to conceal nail heads.

There are two kinds of ridge cap shingles, namely, regular and High Profile Ridge Caps shingles. Regular caps consist of single layer cut-up strip shingles, whereas High Profile Ridge Caps are ready made. High Profile Ridge Caps are also double layered shingles that ensure multi-layer protection at the highest stress areas of the roof (the hips and ridges). This accentuates the natural beauty of your new asphalt shingle roof, while providing the look of thick wood shakes.

8) Fastening and Cleanup

Now that the ice and water membrane, underlayment, flashings, shingles and ride caps are in place it’s time to fasten everything and begin cleanup.

The bottom of vents, chimneys, skylights and wall flashings are not covered by shingles. This is to help 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 cleanup. At National Star Roofing Specialists, we make sure all debris is removed from site, and use a magnetic roller to catch and remove any loose nails and staples.
