There are different ways water can get into the home through the roof. The most common one is when the shingles have gaps, cracks, or other deformities that allow water, ice, or snow to get underneath them, and eventually into the home.
Small leaks can take months and sometimes even years before they become evident to the homeowner. During this time the water is slowly eroding wood, underlayments, insulation and drywall. Over time, these materials lose their effectiveness for their intended purposes.
Wooden materials can start to rot from too much water, which can lead to mold and mildew. Another issue is where they are exposed to periods of wetness and dryness. This causes pre-treated wood to lose its protection and could attract wood eating pests, like termites, as well as to weaken.
With insulating materials, when they are wet, the water causes heat/cold air to transfer from the interior/exterior of the home. So you home will seem warmer in the summer and colder in the winter. In addition, the insulation can rot, as well as promote mold and mildew growth.
Common Causes of Roof Leaks
There are different causes why roofing systems will leak, and cold include one or more of the following:
- Broken, Cracked or Missing Shingles
- Cracked/Broken Roof Vent Seals/Bootings
- Cracked/Damaged Skylight Seals/Bootings
- Cracked/Damaged Chimneys
- Damaged/Missing Flashing
- Improper Sealing of Valleys
- Improper Installation of Eaves/Gutters
Determining the source of a roof leak requires the help of an expert and professional roofer. While you will already know where the water is leaking inside the home, or are noticing discolouration on your ceiling or walls, the actual source of the leak is rarely, if ever directly above these areas. Rather the source of the leak is often in an entirely different location due to how the water is flowing once it gets under the roof and into your home.
Furthermore, there is one type of leak that is not a roof leak – when it is caused from condensation in your attic. This type of leak occurs when your attic does not have sufficient insulation. As cold and hot air meets in the attic, it creates condensation, which can create enough water to make it appear like you have a roof leak.
Why Leaks Need Repaired
There are several safety issues with not addressing and fixing a leaky roof. Support structures can rot, collapse, and sink into the home. The ceiling could collapse and there could be damage to interior support structures. Even the roofing system could start sagging and collapse into the attic.
Ignoring a leak will not resolve the problem, but rather allow it to become worse. If you notice signs of roof leaks in your home, call Logik Roofing at 905.424.7469 today to schedule a roof inspection. We also can help resolve problems where your home has insufficient attic insulation.
