Common Causes of Roof Leaks and How to Prevent Them in Janesville, WI

A sturdy roof is the shield that protects your home from the elements. But even the strongest shield can weaken over time. Roof leaks are a homeowner’s worst nightmare, causing water damage, mold growth, and a hefty repair bill. The good news is that many leaks can be prevented with proactive maintenance and awareness of potential problems.


At Wisco Roofing and Windows, we’re committed to keeping your home dry and safe. In this blog, we’ll explore the most common causes of roof leaks and provide valuable tips to help you prevent them.

Common Culprits of Roof Leaks:

Worn or Damaged Shingles: 

Shingles are the first line of defense against rain and snow. Over time, asphalt shingles dry out, crack, and curl, losing their ability to repel water. Wind, hail, and excessive foot traffic can also damage shingles. 


Solution: Regularly inspect your roof for signs of shingle damage. If you notice missing, cracked, or loose shingles, contact a qualified roofing contractor like Wisco Roofing and Windows for repairs or a roof replacement.


Flashing Failures: 

Flashing is the thin metal used to seal around chimneys, vents, skylights, and other roof penetrations. Improper installation, corrosion, or loose nails can cause gaps in the flashing, allowing water to seep into the underlayment and eventually into your home. 


Solution: Pay close attention to the flashing during your roof inspections. Look for rust, cracks, or gaps that need to be addressed by a professional.


Clogged Gutters: 

Gutters are designed to channel rainwater away from your home. When they become clogged with leaves, debris, and shingle granules, water can back up under the shingles and seep into the roof. Overflowing gutters can also damage the fascia boards and soffits. 


Solution: Clean your gutters regularly, especially after heavy storms. Consider installing gutter guards to minimize future clogging.


Ice Dams: 

In cold climates, ice dams can form at the edge of your roof where warm interior air meets the cold exterior. As snow melts and refreezes, it builds up under the shingles, creating a dam that prevents water from draining properly. This trapped water can find its way under the shingles and into your home. 


Solution: Proper attic ventilation helps reduce ice dam formation. You can also install ice and water shield underlayment in vulnerable areas.


Poor Attic Ventilation: 

A stuffy attic is an invitation for trouble. Inadequate ventilation traps heat and moisture, which can lead to condensation under the roof sheathing. This moisture can cause roof rot, mold growth, and eventually leaks. 


Solution: Ensure proper airflow in your attic by installing soffit vents, ridge vents, or a combination of both.


Preventative Measures for a Leak-Free Roof:

Schedule Regular Roof Inspections: 

Don’t wait for a leak to discover a problem. Having your roof inspected by a qualified professional like Wisco Roofing and Windows at least once a year is crucial for early detection and prevention of potential leaks.


Keep Up with Maintenance: 

Regular cleaning of gutters, trimming tree branches away from the roofline, and addressing minor issues promptly can go a long way in preventing major problems down the road.


Consider Roof Replacement: 


Roofs have a lifespan, typically lasting between 15-30 years depending on the material. If your roof is nearing the end of its expected lifespan, consider a proactive roof replacement before leaks become a concern. Wisco Roofing and Windows offers a variety of high-quality roofing materials and expert installation services.


When to Call a Roofing Contractor:

If you suspect a roof leak, don’t delay! Ignoring a leak will only worsen the damage and increase the repair cost. Here are some signs that indicate you need to call a professional roofing contractor:


  • Visible signs of water damage on ceilings or walls:
     Water stains, peeling paint, or discolored drywall are all telltale signs of a leak. The leak may be originating from the roof, but it could also be caused by plumbing issues or condensation. A qualified roofing contractor can diagnose the source of the leak and recommend the appropriate course of action.
  • Mold growth in the attic: Mold thrives in damp environments. If you discover mold growth in your attic, it’s a strong indication of a roof leak or inadequate ventilation. Mold can pose serious health risks, so it’s crucial to address the issue promptly. 

  • Unexplained increases in your utility bills:
     A drafty attic due to a roof leak can force your HVAC system to work harder to maintain comfortable temperatures inside your home. This can lead to a noticeable increase in your energy bills. 

  • Sagging or buckling roof deck:
     The weight of water pooling on your roof can cause the roof deck to sag or buckle. This is a serious problem that requires immediate attention. 

  • Increased exposure to sunlight in the attic: 
    Tiny holes or gaps in your roof can allow streaks of sunlight to shine through into your attic. While this may seem minor, it’s an indication that water can also be getting through and causing unseen damage.

  • Animal activity in the attic: 
    Animals like squirrels and raccoons can sometimes gain entry into your attic through gaps or holes in your roof. Their presence can damage insulation, chew on electrical wires, and leave behind droppings that can attract further pests and contribute to mold growth.
