Roof Replacement vs. Repair

Roof Replacement vs. Repair: How Glenview Homeowners Can Decide

One of the most common questions we hear from homeowners is, “Can my roof be repaired, or do I need to replace it?” The answer depends on several factors, from the type and extent of the damage to the age of your roof. Making the right call can save you thousands in the long run.

Step 1: Evaluate the age of your roof

In Glenview, weather conditions mean asphalt shingle roofs often reach the end of their life around 20–25 years. If your roof is:

  • Under 10 years old with isolated damage → repairs are usually the smarter choice.
     
  • Over 20 years old with multiple issues → replacement is often more cost-effective long term.
     

Step 2: Assess the extent of the damage

  • Localized damage (e.g., a few missing shingles from wind) can usually be patched.
     
  • Widespread deterioration (e.g., curling shingles across large areas) often signals it’s time for a new roof.
     
  • Structural damage (e.g., sagging or rotting decking) may require replacement for safety.
     

Step 3: Consider recurring problems

If you’ve had to repair the same leak or problem area more than once, it may indicate an underlying issue that won’t be resolved without replacing the roof.

Step 4: Compare costs over time

A repair might be cheaper upfront, but if your roof is near the end of its life, repeated repairs can add up to more than the cost of a replacement.

Step 5: Factor in energy efficiency and home value

New roofing materials can improve insulation, reduce cooling costs, and boost curb appeal — all of which can increase your home’s resale value.
