We will go through what Class 4 Impact resistant shingles are and why you should consider spending a bit more on these shingles for your home in Calgary. We will also look at the City of Calgary rebate available for these kinds of shingles and potential home insurance savings.
What are Class 4 Impact Resistant Shingles?
Roofs are known to be the first line of defence against severe weather for your home. Having Impact Resistant shingles (IR Shingles) makes that line of defence more durable against the extreme weather your roof can experience here in Calgary, Alberta.
Many factors contribute to a shingle’s ability to withstand hail damage and other severe weather. Class 4 shingles can be some of the best roofing shingles you can get to protect your home.
How are IR shingles more durable?
- Polymer-based mesh for improved reinforcement is placed on the back of the shingle, mitigating splitting and other damage from impact from extreme weather like hail.
- SBS (Styrene-butadiene-styrene) polymers or other Rubber-like polymers are built into the composition of the shingle to create a ruggedization of the material. This leads to more give in the shingle from impacts, even from objects in high wind conditions.

This additional cost can be offset by reduced insurance premiums and a new rebate that the City of Calgary is now offering.
