Roof Repair or Replacement? How to Know.

In this video Heriberto Garcia Jr from Carpenters Touch goes over 5 signs that it might be time to replace your roof. He also offers other explanations that should be investigated.

5 Signs You Need a Roof Replacement

These are the five signs that you need a roof replacement before it's too late.

1. Missing Shingles

If you're walking around your home and notice missing shingles, that's a clear warning sign. This is often caused by wind damage, hail damage, or improper installation. If shingles were nailed incorrectly, they can easily come loose and slide off over time.

A few missing shingles on an otherwise sound roof can be a repair; our guide to replacing a damaged shingle shows what that involves.

2. Roof Leaks Inside Your Home

If you see water leaking inside your house during rain, it's likely a roofing issue. However, some leaks can come from plumbing or HVAC systems, so it's important to confirm the source. If the leak is consistent during rainfall, it's often a sign that your roof may need replacement.

3. Sagging Roof Decking

If your roof appears to be sagging, especially in the middle, this is a serious structural warning sign. This is often caused by excess weight from snow, multiple roofing layers, or prolonged water damage. A sagging roof typically means it's time for a replacement, not just a repair.

Our roof decking repair cost guide explains how damaged decking is replaced.

4. Granules in Your Gutters

If you notice a buildup of shingle granules in your gutters, your roof may be deteriorating. Granules protect the asphalt layer from sun, rain, and weather damage. Once they wear off, shingles become brittle, crack, and fail much faster.

Our guide to what roof granules in your gutters mean explains how much is normal.

5. Algae or Moss Growth

If your roof looks like it has moss, algae, or even "grass" growing on it, that's a major sign of aging. This typically means the roof is past its expected lifespan and losing its protective qualities.

Other Warning Signs Inspectors Look For

Home inspectors and roofers also check for these signs of an aging roof:

• Cracked or curling shingles

• Worn shingle edges, or the fiberglass mat showing through

• Daylight visible through the roof deck from the attic

• A roof at or past its expected lifespan (25 to 30 years for architectural shingles)

Our guide to how to tell when your roof is nearing the end of its life covers these from a home inspector's point of view.

When Should You Call a Roofing Professional?

If you're seeing one or more of these signs, it's time to have your roof inspected. In many cases, these issues indicate that a full roof replacement may be necessary rather than a simple repair.

If you notice multiple signs like leaks, sagging, or widespread shingle damage, it's best to have a professional inspection as soon as possible. Early evaluation can prevent more expensive structural damage.
