What to Watch For:
• Missing, curled, or damaged shingles

What to Watch For:
• Cracks, peeling, or warping

Siding keeps the elements out and the comfort in. Damaged siding can lead to insulation problems and hidden rot.
3. HVAC Systems (Heating + Cooling)

• Tankless (On-Demand): 15–20 years
• Heat Pump Water Heaters: 10–15 years
What to Watch For:

Hot water touches every part of daily life from hygiene to laundry. Knowing your heater’s lifespan helps prevent cold surprises.
5. Electrical System
• Service Panel: 25–40 years
• Copper Wiring: 50–70+ years

6. Plumbing System

• Cast Iron (for drains): 75–100 years

If you’re buying your first home, this isn’t just trivia—it’s a survival guide. Every system has a lifespan. Knowing what lasts, what’s failing, and what to look for helps you ask better questions, budget wisely, and avoid major surprises after closing.
