Roof Repair vs Replacement: How to Decide What Your Home Needs

When your roof starts showing signs of wear and tears — missing shingles, ceiling stains, or sagging spots — the big question becomes should you repair it or replace it?

At Eleven Exterior, we offer free roof inspections in Middlesex County, NJ and Montgomery County, PA to help homeowners like you make the right decision. Before you schedule an inspection, these helpful guides will empower you to make informed decisions, saving both time and money on your roofing project.

1. How Old Is Your Roof?

The age of your roof is often the first clue.

Roofing Material	Typical Lifespan
Asphalt Shingles	20–35 years
Metal Roof	50–70+ years
EPDM / TPO (Flat Roof)	20–40 years
Slate or Tile	70–100+ years

If your asphalt shingle roof is more than 15–20 years old, and you're seeing leaks or shingle loss, replacement is usually more cost-effective in the long run.

There are 50-year or lifetime architectural asphalt shingles produced in the US, but they have not been used for the full duration. If you suspect any potential leaks or internal damage, a professional inspection is essential to assess the condition of the shingles.

2. What’s the Extent of the Damage?

Here's how to gauge whether you’re dealing with a roof repair vs replacement situation:

Choose Repair If:

• Damage is localized (e.g., one section of the roof or flashing is affected)

• The roof is relatively new

• No structural decking is compromised

• It’s a first-time issue

Choose Replacement If:

• Multiple areas are damaged

• You’ve already repaired the same spot before

• There are sagging spots or signs of wood rot

• You see granules in gutters or curling shingles across large areas

TIP: if your roof has multiple visible issues from the ground or aerial photos, it’s time for a deeper look.

3. Is There Water Intrusion?

Roof conditions visible from the ground often appear normal, but hidden issues beneath the surface—like water leaks—can lead to costly repairs, including structural damage.

Watch for:

• Water stains on ceilings

• Bubbling paint or drywall

• Musty smells or mold

Water stains surround a ceiling light fixture, indicating a potential leak in need of urgent repair.

Leaks reaching your interior ceilings or walls are a serious warning sign. If such damage is detected, immediate action is essential to prevent costly repairs.

4. Cost Comparison: Roof repair vs Replacement

Let’s break it down:

Option	Average Cost Range (1,700 sq ft roof)	When to Consider
Repair	$500–$3,000+	Minor damage
Replace	$10,000–$20,000+	Age + widespread damage

Short-term vs long-term:

• Repairing your roof is more affordable in the short term, but it typically doesn't increase your home's value. It also carries the risk of recurring issues, leading to repeated repair costs and time. If the damage is isolated and unlikely to return, a repair can be a practical and cost-effective solution.

  
  

• Roof Replacement is more expensive upfront, but a full replacement adds long-term value, improves energy efficiency, and offers peace of mind — especially if you plan to sell your home within the next 5 to 10 years.

Speak with a professionally trained roofing contractor to assess your roof and help you choose the best option based on your home, goals, and budget.

5. Are You Planning to Stay or Sell?

• Staying long-term? A new roof improves energy efficiency, comfort, and long-term value. If the damage is minor, a repair may be a smart, budget-friendly option.

  
  

• Selling soon? A roof replacement boosts curb appeal and buyer confidence, helping you sell faster and often at a higher price. However, if the roof is in good condition with only minor issues, a professional repair can help you pass inspection without the full cost of replacement.
