What are the best shingles to use?
If you are looking for an affordable and durable shingle that will stand up to Calgary weather and have a class 4 hail-resistance, many roofing contractors recommend going with Malarkey Legacy. They are not only extremely durable, they also look attractive and come in a variety of colors. Their lifetime warraenty for up 209 km/h makes them a go to option for Calgarians. Another added benefit to these is that they come with an optional Scotchguard TM Protector from 3M for protection against algae.
