Knowing the most common causes of roof leaks can help you spot potential issues early. By recognizing warning signs like water stains or missing shingles, you can take action sooner. You’ll be able to hire a professional roofing contractor to fix your roof before more problems arise.


In this blog, we’ll discuss some of the most common causes, so you can be better prepared.


Water damage from a leaking roof can be dangerous if left untreated


Even the smallest leaks can impact your roof down the road. Over time, water damage can compromise the integrity of your home. 


If water is able to seep through your ceilings and walls, it can lead to mildew and potential mold growth causing the framework of your home to warp and rot. 


You want to prevent water damage before it can reach your drywall, insulation, and electrical wiring. Protecting your home from the effects of roof leaks will keep your home safe and secure. 


What are some common causes of leaks?


Water damage to your roof can occur for various reasons, including: 


  • Worn or damaged asphalt shingles and roof flashing

  • Severe weather, including heavy rain, wind, and hail 

  • Ice dams caused by water build-up in the winter 

  • Improper installation of roofing materials, worn or damaged shingles 


Damaged Shingles and Flashing 


Damaged shingles and flashing are among the most common causes of roof leaks, especially in older homes. Over time, shingles become more susceptible to cracking and curling, making it harder to protect your roof from water entering through the gaps.

Damaged shingles and flashing are common culprits of roof leaks.

Flashing is a material used to direct water away from vulnerable areas on your roof. It is found on joints and seams and around chimneys and skylights to seal gaps and prevent water from seeping through. 



Regular roof maintenance and roof inspections can help identify damaged shingles and flashing before they lead to costly repairs.





Severe Weather 


Severe weather, like strong winds and hail, can harm your roof. Hail can crack your shingles, while heavy winds may cause them to tear off completely. Wind can also blow debris onto your roof, further weakening it.

You can help protect your roof with high-quality roofing materials like shingles that can withstand hail impact, like Impact Resistant Shingles. However, this damage can still leave your roof vulnerable to leaks over time. 


Ice Dams 


Ice dams form when warm air from your attic melts the snow on your roof, and the water flows to the cold edges and refreezes. Ice build-up affects proper drainage. 


Excess water can clog your gutters and seep into any small cracks in your roof causing water to seep into your attic. 


Improper Installation 


Improperly installed shingles and flashing can increase the risk of roof damage. While it’s normal for roofing materials to deteriorate over time, it’s not normal for a new roof to leak. 


When hiring a roofing company for roof repairs or replacements, you want to ensure the contractor is fully licensed and insured and comes highly recommended by other homeowners.
