Building Systems: Frequently Asked Questions
- How long does a furnace last in Calgary? +
- A well-maintained mid- or high-efficiency forced-air furnace typically lasts 15–20 years in Calgary. High-efficiency condensing units commonly run 18–25 years with annual servicing.
- How long does an asphalt shingle roof last in Calgary? +
- Standard 3-tab asphalt shingles last 15–18 years; architectural and impact-rated shingles 20–30 years. Calgary's hailstorms can cut that significantly — many roofs are replaced after a single insurance claim.
- How long does a hot water tank last? +
- Standard atmospheric gas tanks: 8–12 years. Power-vent and high-efficiency tanks: 10–15 years. Anode rod replacement extends life; soft water shortens it.
- What is a home envelope inspection? +
- It evaluates the components that separate inside from outside — cladding, windows, doors, roof, foundation walls — for water, air, and thermal control. It is the most common source of expensive repairs in Calgary homes.
- When is thermal imaging useful in a home inspection? +
- Thermal imaging finds missing insulation, air leakage, moisture intrusion, overheating electrical components, and radiant floor loop layout. It is most accurate when there is a meaningful temperature difference between inside and outside.
