Asphalt Shingles Calgary – Roofing Calgary

Timberline HD Barkwood House PhotoThe original Canadian roof system, asphalt shingles have stood the test of time and have evolved about as much as the automobile has!

Once upon a time, asphalt shingles were made with layers of wood, asphalt, and granule and lasted between 5-8 years after having been installed. Although the fabrication process is still fundamentally similar, modern asphalt shingles are made with a fiberglass base, layers of specially formulated asphalt, and specifically cut and shaped granules, allowing the typical shingle to last, realistically, for roughly 25 years in a properly ventilated roof system. Some asphalt shingles can even last up to 40 years.

Now let’s talk about warranties, and how long a well installed Calgary asphalt roof system should last. Shingles have a manufacturers’ rating that differs a fair bit from their realistic life span. Let us differentiate here between manufacturer’s defect warranty and realistic life span.

A manufacturer’s defect warranty means exactly what it is called. It is a warranty against defective products. If an asphalt shingle in Calgary wears down from age, wind, snow, ice and sun exposure, it did so naturally, this is not classified as a manufacturers warranty. A manufacturer’s warranty covers a product that wears down, falls apart, changes color or deteriorates abnormally quickly. Therefore, if a shingle is called a “30 year shingle by manufacturers warranty”, this means the manufacturer will cover any defects, often pro-rated, for that 30 year period. If your shingles deteriorate naturally before that 30 year warranty is over, this does not qualify as a warranty claim as no defect has presented itself.

The realistic life span for Calgary asphalt shingles is roughly 20% less than their manufacturers’ warranty coverage period. This is mostly due to a combination of our dry climate, Chinook winds, rapidly changing temperatures, and the infamous Canadian winters. Therefore, a 30-year shingle will typically last roughly 24 years, a 40 year shingle will typically last roughly 32 years and a 50 year asphalt shingle in Calgary will last roughly 40 years.
