Your roof is your home's first line of defense against Michigan's harsh weather — from heavy snow loads to summer hailstorms. But most homeowners don't think about their roof until water is dripping through the ceiling. By then, the damage is usually far more expensive to fix.

Here are 7 warning signs that your roof may need replacement soon:

1. Missing or Curling Shingles — If shingles are visibly missing or the edges are curling up, your roof's protective layer is compromised. This can happen due to age, poor installation, or wind damage.

2. Granules in the Gutters — Asphalt shingles shed granules as they age. Finding excessive granules in your gutters is a sign your shingles are nearing the end of their life.

3. Daylight Through the Roof Boards — If you can see sunlight from your attic, you've got gaps. Water and cold air will follow.

4. Sagging Roof Deck — A drooping or sagging roof deck indicates structural damage, often from long-term moisture exposure. This needs immediate attention.

5. Your Roof Is 20+ Years Old — Most asphalt shingle roofs last 20-30 years. If yours is approaching that age, it's time for a professional inspection.

6. Moss and Algae Growth — Green or black streaks on your roof indicate moisture retention, which accelerates shingle deterioration.

7. Increasing Energy Bills — Poor roof insulation or ventilation causes HVAC systems to work harder. A spike in heating or cooling costs can point back to your roof.
