Not all roofing problems are obvious. Some start small, but if ignored, they can lead to major damage and costly repairs. Whether you own a newer home or live under an older roof, staying alert to warning signs can save you thousands.

In this blog, we break down the five most common signs that your roof needs repair right now in 2025. If you notice any of these, it is time to call a professional before things get worse.

1. Water Stains or Leaks Inside Your Home

One of the most obvious red flags is seeing water spots on your ceilings or walls. Even small stains can be a sign of a slow leak.

If left untreated, leaks can lead to:

• Mold and mildew

• Damaged insulation

• Weakened drywall and framing

• Higher energy bills due to moisture problems

Do not wait until water is dripping. Act at the first sign of staining.

2. Missing or Damaged Shingles

Shingles protect your roof from water, wind, and UV rays. If some are missing, cracked, curling, or losing granules, your roof is vulnerable.

Common causes include:

• Storm damage

• Aging materials

• Poor installation

From the ground, you might notice uneven sections or bald spots. If you see any, book an inspection quickly.

3. Sagging Areas on the Roof

A roof should have a straight, even surface. If parts of it appear to sag or dip, that is a major structural concern.

Possible causes:

• Water damage weakening the decking

• Poor ventilation causing trapped moisture

• Rotting support beams or plywood

Sagging is not just a cosmetic issue. It can lead to a full roof collapse if ignored.

4. Higher Energy Bills Without Explanation

If your heating and cooling bills suddenly go up, your roof might be the reason. A damaged roof lets air escape and makes your HVAC system work harder.

Signs of poor insulation or ventilation include:

• Hot or cold spots in rooms

• Drafts near attic or upper levels

• Ice dams in winter

Getting your roof checked can stop energy loss and lower your monthly costs.

5. Moss, Algae, or Mold Growth

Moss or green patches on your roof might look natural, but they are a serious warning. These growths trap moisture and speed up wear and tear.

They also:

• Damage shingles

• Cause rot

• Attract insects

Cleaning might help temporarily, but if growth returns fast, it is time to repair or replace that section of the roof.

Bonus Sign: Your Roof Is 15 Years or Older

Even the best roofing materials wear down over time. If your roof is over 15 years old, regular inspections are a must. You do not have to wait for damage. Preventative maintenance can extend your roof’s life and reduce the chance of expensive surprises.
