What the inspector told me about your roof

roof partsIf a real estate listing does not give the roof’s age, it’s likely near the end of its life. Roofs are expensive (as are new windows and furnaces). When looking at buying a home, pay special attention to roofs.

A new roof can cost anywhere from $4000- $10,000, depending on the size of your roof. Generally speaking, if you measure the size of your roof, then calculate the cost of shingles at your local Rona, Lowes or Home Depot then double it to add labor cost. That will give you a good idea of what your new roof should cost.

Asphalt shingles last 12-20 years. Don’t rely on manufacturers’ ratings. 25 year shingles might need replacing in 12 years. 40 year shingles often need replacing in 20. Shingles wear out faster where there are lower slopes and with more sun exposure. The southwest roof will wear out faster than the northeast roof.

The average roof life is 15 years. If your house is 30 years old, you’re likely due for a new roof.
