Roof Repair vs. Replacement in NJ: How to Decide

Should you repair the damage or replace the entire roof?

Your roof is one of the most important parts of your home — but it won’t last forever. When problems arise, the big question for New Jersey homeowners is: Should you repair the damage or replace the entire roof?

At LGM Roofing, we’ve helped countless homeowners in Bloomfield and across NJ make the right call. Here’s a practical checklist to help you decide.

Step 1: Assess the Age of Your Roof

Asphalt shingles: Typically last 20–25 years in NJ’s climate
Metal roofs: Can last 40+ years with proper maintenance
Flat roofs: Usually last 15–20 years

💡 Rule of Thumb: If your roof is nearing the end of its expected lifespan, replacement may be the smarter investment.

Step 2: Evaluate the Extent of Damage

✅ Repair May Be Enough If:

✔️ Damage is limited to a small section

✔️ Only a few shingles are missing or cracked

✔️ There’s no widespread water damage or sagging

❌ Replacement May Be Best If:

✔️ Damage affects more than 30% of the roof

✔️ You have recurring leaks in multiple areas

✔️ There’s structural damage to the decking

Step 3: Check for Water Damage

Leaks aren’t just annoying — they can lead to mold, rot, and compromised structural integrity.
If water damage is extensive, replacing the roof may prevent ongoing repair costs.

Step 4: Consider Your Budget & Long-Term Plans

✔️ Short-term solution: Repairs cost less now, but may not last if the roof is aging.

✔️ Long-term investment: Replacement costs more upfront but provides decades of protection.

If you plan to sell soon, a new roof can also increase home value and boost curb appeal.

Step 5: Factor in New Jersey’s Climate

NJ’s hot summers, heavy rains, and snowy winters can accelerate wear.
A replacement may better protect against the extreme seasonal changes that can weaken older roofs.
