What should I know about hail damage and roofing when buying a Calgary home?
Calgary can experience significant hailstorms, so roof condition and exterior damage are important considerations when purchasing a property. During a showing, we'll look for visible concerns involving shingles, siding, eavestroughs, and other exterior components, although damage isn't always obvious. I recommend asking about previous hail claims, repairs, and the age of the roof. A qualified home inspector or roofing contractor can provide a more detailed assessment when needed. Understanding the condition of these components can help you anticipate future maintenance expenses.

Hail Damage and Roofing: Key Points


  • Calgary is one of the most hail-prone cities in Canada.
  • Roof, siding, and eavestrough damage isn't always obvious.
  • Ask about past hail claims, repairs, and the age of the roof.
  • Impact-resistant roofing can reduce future damage and may lower insurance costs.

Hail Season in Calgary


Most severe hailstorms occur from June through August. Major storms, including the June 2020 storm in northeast Calgary, have caused more than a billion dollars in damage.


Signs of Hail Damage


  • Dents or granule loss on shingles
  • Cracked or dented siding, especially vinyl
  • Dented eavestroughs, downspouts, and vents
  • Damaged window screens or frames
  • Granules collecting in eavestroughs

Questions to Ask the Seller


  • How old is the roof?
  • Have there been any hail claims?
  • Were repairs completed, and is there documentation?
  • Is the roof made of impact-resistant materials?

Impact-Resistant Roofing


Class 4 impact-resistant shingles are designed to better withstand hail. Some insurers offer discounts for these materials, and some builders now install them as standard on new homes. The City of Calgary's former roofing rebate program has ended.


Assessing Risk Before You Buy


A home inspector can identify visible damage, and a roofing contractor can provide a closer assessment. Checking insurance costs during your condition period can also help. I'll help you ask the right questions so you understand the home's condition and future maintenance needs.
