Your roof is your home’s first line of defense against the elements, but over time, exposure to Wisconsin’s harsh weather can lead to wear and tear. From heavy snowfall in winter to strong summer storms, your roof endures a lot throughout the year.


Many homeowners don’t realize there’s a problem until a leak appears, but by that point, damage may already be extensive. Being proactive and recognizing the early warning signs of roof damage can save you from costly repairs and unexpected headaches. In this guide, we’ll walk you through the most common indicators that your roof may need professional attention.

1. Water Stains on Ceilings or Walls

One of the most obvious signs of a roofing issue is water stains on ceilings or interior walls. This usually means water is seeping through the roof, possibly due to:

  • Damaged or missing shingles

  • Cracked flashing around chimneys, vents, or skylights

  • Poor attic ventilation causing moisture buildup

Ignoring water stains can lead to mold growth, structural damage, and ruined insulation—all of which can be expensive to fix.

2. Missing, Curling, or Cracked Shingles

Shingles act as a protective barrier for your roof. When they start to crack, curl, or go missing, your home becomes vulnerable to leaks and further deterioration. Common causes include:

  • Aging roof materials

  • Extreme weather like hail, strong winds, and ice buildup

  • Poor initial installation

Regular inspections can help identify problem areas before water starts penetrating your home.

3. Sagging Roof Sections

If your roof appears to be sagging, it could indicate structural weakness due to:

  • Water saturation from leaks

  • Excess weight from snow accumulation

  • Deteriorated roof decking or support beams

A sagging roof is a serious problem that should be addressed immediately to prevent potential collapse or more extensive damage.

4. Granules in Gutters

Asphalt shingles shed granules over time, but if you notice an excessive amount in your gutters, it may be a sign that your shingles are deteriorating. Granule loss can lead to:

  • Weakened UV protection, making your shingles more brittle

  • Reduced lifespan of your roof

  • Higher risk of leaks and internal water damage

Checking your gutters periodically can help catch this issue early.

5. Drafts or Moisture in the Attic

Your attic is a key indicator of your roof’s condition. If you experience:

  • Cold drafts even when windows are closed

  • Moisture buildup or mold growth

  • Visible daylight coming through the roof boards

Then it’s time to have a roofing professional inspect for potential insulation gaps, ventilation issues, or leaks.

6. Increased Energy Bills

A damaged roof can lead to poor insulation and ventilation, forcing your HVAC system to work harder to maintain indoor temperatures. If you’ve noticed unexplained spikes in your energy bills, your roof may not be properly protecting your home from temperature fluctuations.
