Choosing a Roof Type

Which Type of Roof is Right for Me?

“Roof shingles” are any type of roofing material that is laid in overlapping sections to protect a structure from water intrusion and weather damage. While most roofing shingles are flat, some can be curved, rectangular, diamond-pattern, or laid in a variety of styles. There are many exciting options of roof styles.


Here are the most important factors to consider when comparing your options:


Cost is a factor in every decision we make as consumers. There are many factors to consider, such as whether the investment will pay off over the product’s lifetime, or whether it is truly worth paying for a luxury item on appearance alone.

Wind Warranty

In the last five years, Calgary has seen wind gusts upwards of 80 kilometres per hour. If a piece of roof is blown off, it can have dire consequences to the roof’s underlayment once it is exposed to the elements.

Hail Resistance

Hail resistance is a roof’s ability to withstand impact without sustaining damage. The higher the resistance, the better your roof will do during a hail event. Hail damage is one of the most common precursors to a leaky roof, as well as many other headaches such as mold and structural damage.

Required Maintenance (Running Costs)

In the time we’ve been installing roofs, we have yet to come across a customer that wants to spend more time and money maintaining their roof. While all roofs require some maintenance, you should always keep the running cost in mind when considering a roof type.
