It’s never fun to discover that your roof is leaking. Not only is it a hassle to fix, but it can also cause various issues inside and outside your home. A leaky roof can lead to big problems, from mold and mildew to structural damage.

The top issues caused by a leaky roof are:

  • Water Damage: Water damage is one of the most common issues caused by a leaky roof. Water can enter your home through a hole in the roof or a crack in the shingles or flashing. It can result in water stains on the walls and make the paint peel or bubble up.
  • Mold Growth: Mold growth is another common issue caused by a leaky roof. The moist environment created by a leaky roof is the perfect environment for mold to grow. Mold spores cause health issues, such as allergies and headaches.Mold growth can cost a significant amount of money to get rid of once it has taken hold.
  • Structural Damage: A leaky roof can cause structural damage to your home over time. If the leak is left unchecked, it can wreck your entire roof structure, starting from the wood beams and joists, weakening the support for your roof.
  • Attic Damage: If you have a leaky roof, don’t be surprised if your attic is the first area to be affected. Anything inside the attic, from the insulation to the wooden structure and your personal belongings, will get wet and eventually grow mildew. And worst case, sustain damage and rot.
  • Energy Loss: If your roof is leaking, it can cause your energy bills to skyrocket. The water can damage your insulation or create holes in your ceiling and cause heat to escape from your home, leading to higher energy bills.
  • Pest Infestations: The moist environment caused by a leaky roof can attract pests like rats and insects into your home. Meanwhile, stagnant water may become a breeding ground for disease-carrying mosquitoes. 
  • Health Risks: The dampness caused by a leaky roof can also cause health risks. The mold and mildew that grow in the moist environment can cause respiratory problems, exacerbate existing allergies and asthma and bring disease-carrying pests like rodents and mosquitoes.
  • Damage to Personal Belongings: The moisture from a leaky roof can also damage your personal belongings. Your furniture, books, and electronics might get soaked.
