How to Spot the Signs That Your Roof Needs Repair

Your roof works hard year-round to protect your home from rain, wind, snow, and sun—but over time, even the best roofs can show signs of wear and tear. Knowing what to look for can help you catch small issues before they become expensive problems.

At Precise Exteriors, we’ve seen how early detection can save homeowners time, money, and stress. Here’s how to tell if your roof needs repair.

1. Missing or Damaged Shingles

If you notice shingles that are cracked, curling, buckling, or completely missing, it’s a clear sign your roof is compromised. These gaps can allow moisture to seep into the underlayment, leading to leaks and structural damage.

What to do: Check after storms or strong winds, and look for debris like shingles in your yard or gutters.

2. Water Stains on Ceilings or Walls

Brown or yellow stains inside your home may indicate a roof leak. These often show up in the attic or on upper-level ceilings and walls and can mean water is seeping through under the shingles.

Tip: Don’t ignore even a small stain—water damage spreads quickly and can lead to mold and rot.

3. Sagging Roof Lines

Your roof should appear straight and even. If you notice dips, sags, or a wavy appearance, it could point to serious structural issues caused by prolonged water damage or weakened decking.

Act fast: A sagging roof is a red flag that needs immediate professional attention.

4. Granules in the Gutters

Shingle granules help protect your roof from UV rays and weather damage. If you’re finding granules in your gutters or downspouts, your shingles may be deteriorating and nearing the end of their life.

This is especially common in older roofs or after a hailstorm.

5. Moss, Mold, or Algae Growth

While moss may look harmless, it retains moisture and can break down roofing materials over time. Mold and algae can also be signs of trapped moisture and poor ventilation.

Best practice: Keep your roof clear of debris and schedule regular maintenance to prevent growth.

6. Increased Energy Bills

If your energy bills are rising without explanation, your roof’s insulation or ventilation might be to blame. A damaged or aging roof allows heat to escape in winter and traps it in summer, forcing your HVAC system to work harder.

An inspection can determine if the roof is contributing to your energy inefficiency.
