Mould Damage from Roof Leaks

Moulds caused by roof leaks can damage your home and your health.

Without proper leak barriers and attic ventilation, you may experience leaks or excess moisture causing mould growth. Mould can grow not only in your attic but anywhere in the home that an undetected leak is present.

Most homeowners don’t even consider mould to be a problem unless they can actually see it. But mould damage often starts in invisible areas like attics, basement, air ducts, or even wall cavities.

Mould is a Bigger Problem Than You Think

There are many articles and studies that confirm mould is a serious health issue:

  • Health Canada considers mould growth in residences to be a potential health hazard.
  • According to a Mayo Clinic study, nearly all chronic sinus infections are a result of moulds.
  • It is estimated that 50% of homes have mould problems.
  • A 300% increase in the asthma rate over the past 20 years has been linked to moulds.
  • The Environmental Protection Agency considers all moulds to have the potential to cause health effects.

Mould Can Cause Many Health Issues

Anyone may suffer adverse effects from the existence of mould. Those most susceptible include the elderly, pregnant women, infants and young children, and people with allergies, chronic respiratory illness and/or chemical sensitivities, as well as those with weakened immune systems.

According to Canada Toxic Mould Inspection & Remediation, mould can cause the following reactions:

  • respiratory problems, such as wheezing and difficulty in breathing
  • nasal and sinus congestion
  • eyes-burning, watery, reddened, blurry vision, light sensitivity
  • dry, hacking cough
  • sore throat
  • nose and throat irritation
  • shortness of breath
  • skin irritation
  • central nervous system problems (constant headaches, memory problems, and mood changes)
  • aches and pains
  • possible fever

Check for Mould Damage

Although leaks and excess moisture can come from many sources, it is a good idea to check your roof and attic and make sure there are no problems.
