WHAT ARE THE COMMON CAUSES OF ROOF LEAK?

Repairs are one of the most dreadful tasks for any homeowner, especially if it is a roof leak. Water in a roofing system can easily find its way into the home through vulnerable structures like a clogged gutter, missing shingle or punctured layer on the roof. Once the water is inside, it can cause significant damage to your house. A small unnoticed drip may seem harmless but it could be a sign of water damage. A damaged eavestrough or a clogged gutter can cause your roof to leak. So get your Kitchener eavestrough repair done. Following are some of the common causes for a roof leak:

  1. Old Material for Roofing:
    All roofing materials are bound to get old with time and when they do, you will have to spend more and more money on their repairs. With time, the roof becomes exposed to varying temperatures, which causes the material to expand and contract and eventually causes cracking. Since the roof is exposed to sunlight, the harsh UV rays of the sun cause the roofing material to deteriorate and turn brittle. It is one of the main reasons why the roof starts to leak during the end of its life expectancy.
  2. Damaged Chimney:
    As most chimneys are made out of bricks, hence, they are bound to each other by mortar. Though these chimneys could last for several years, the mortar could start to get eroded when exposed to harsh weather conditions, which can cause the water to leak in through the joints. However, this can be easily fixed by applying patches on the joint in order to stop the leak.
  3. Compromised Flashing:
    Usually made out of metal, flashings are applied on danger points to prevent the roof from leaking. For example, flashing can be used to join the roofing material and the chimney at a 90-degree angle. If it hasn’t been sealed properly then water can easily seep in. Poor insulation is another issue with flashing. Flashing needs to remain in place to avoid rusting or cracking.
  4. Missing Shingles:
    When roof shingles go missing, they need to be replaced immediately. Replacing shingles is an easy and one time task. All you have to do is remove the nails from the course below and then slide down the new shingle until it fits perfectly. Once that has been done, you can nail the new flashing securely and properly on the roof. There might be a slight difference in colour after replacing the shingle, this is because the old shingles have weathered over time.
  5. Faults in Vent Boot:
    It is that section of the roof which slides over the plastic vent pipes which protrude from the roof. This vent boot helps to prevent the water from getting into the junction of the roof and pipe. Plastic, metal and rubber are some of the materials which are used in making the vent boot. A damaged vent boot can easily be replaced with a new one.
