Your roof is one of the most important parts of your home, yet it’s easy to forget about it—until something goes wrong. At Twin Mar Roofing, we’ve seen firsthand how small issues can quickly turn into major (and costly) problems when left untreated. Regular roof inspections and early repairs are essential to protecting your home from water damage, mold and structural issues.
Here are 10 key signs you may need roof repair in Harrisburg before things get worse:
1. Missing or Damaged Shingles
If you notice bare spots, curled edges or shingles that are cracked or completely missing, it’s a sign your roof is compromised. Damaged shingles can’t protect your home effectively and can lead to leaks.
2. Water Stains on Ceilings or Walls
Brown stains inside your home are often a sign that water is seeping in from the roof. Even small stains can indicate a significant problem that needs immediate attention.
3. Sagging Roof Line
A roof that sags or dips in the middle can point to structural damage. This can be due to prolonged water exposure or poor roof installation and should be addressed immediately.
4. Granules in the Gutters
If your asphalt shingles are shedding their granules, you’ll notice them collecting in your gutters. This is a sign the shingles are wearing out and losing their ability to protect your home.
5. Light Shining Through the Attic
If you can see daylight coming through your attic ceiling, water can get in, too. This is an urgent issue that needs to be fixed before a major leak develops.
6. Increased Energy Bills
A damaged roof can lead to poor insulation and ventilation, which forces your HVAC system to work harder. If you’ve noticed rising energy costs, your roof might be part of the problem.
7. Mold or Mildew on Exterior Walls
Mold growth or dark streaks along your siding may be caused by improper roof drainage or leaks. Ignoring these signs can lead to serious health and structural concerns.
8. Damaged Flashing
Flashing around vents, chimneys and skylights keeps water out. If it’s bent, rusted or missing, water has a clear path into your home.
9. A Roof That’s Over 20 Years Old
Even if your roof looks fine from the ground, its age matters. Most asphalt shingle roofs last around 20 years. If yours is older, it’s time to start looking for signs of deterioration.
10. Moss or Algae Growth
While it may seem harmless, moss and algae can trap moisture and speed up roof decay. Their presence often signals poor drainage or underlying issues.
