Potential Damage from Roof Leaks

Structural Damage

When a roof leak occurs and is left unattended, it can lead to severe structural damage. Water seeping through the roof can weaken the support beams and rafters, causing them to rot and deteriorate over time. This can compromise the integrity of the entire roof structure, potentially leading to a collapse or significant damage to the overall building.

Mold and Mildew Growth

Another consequence of ignoring a roof leak is the growth of mold and mildew. Moisture from the leak provides an ideal environment for these fungi to thrive. Mold and mildew not only cause unsightly stains and discoloration on walls and ceilings but can also pose serious health risks. Prolonged exposure to mold spores can trigger respiratory issues, allergies, and other health problems.

Damage to Insulation

Roof leaks can also damage the insulation in your home. When insulation gets wet, it loses its effectiveness in regulating temperature and can even become a breeding ground for mold.
