Roof leaks are no strange thing, especially during heavy downpours. Yet, most people seem to overlook the most common causes for roof leaks. While some people may claim they are safe because their roofs are well maintained or are fairly new, they are aren't exempted from roof leaks, unfortunately.
That's right, the causes for roof leaks do not recognise a new property or a well-maintained structure; far from it. But here's what you need to not overlook when evaluating the possible causes for a roof leak before performing roof repairs.
Just in case you didn't know, gutters are the reason water travels out of your roof. Therefore, when these get clogged, probably due to some blockage, water stops flowing out of your roof. Instead, the water pools in one of the roof areas, after which, in no time, it starts seeping through cracks, resulting into a roof leak.
A Cracked Flashing
Well, flashing is often sealed together by use of tar. Over time, however, the tar is likely to corrode, leaving the flashing exposed. This, then, makes the flashing vulnerable to things like wind and water, leading it to crack. And, it goes without saying, a cracked flashing means a leaking roof.
A Cracked Vent Booting
Roof vents are usually fixed by use of some flashing -- before a tight rubber boot is slipped over the area. During harsh weather conditions, however, this flashing can break, leaving a crack in the vents. Furthermore, the roof is likely to decay over time, too, making the vents vulnerable, hence a leaking roof.
Issues with Skylights
Upon installation, it's possible that skylights are not only measured improperly but also are fitted improperly. Such installation mistakes are the reason a roof could leak. Moreover, when the insulation along the edges of the skylights decays, it can be a sure way for a roof to leak.
A cracked Chimney
The motared area around the top of the chimney is the culprit here. Morta, just like we know, is a thick blend of water, sand, and cement. Consequently, it erodes easily during unfriendly weather conditions. Which is enough to cause cracks that let water into the house. You might also want to be on the lookout for holes in the mortared joints, as well as loose flashing, which are just but other pinpointers.
Improperly Sealed Valleys
Valleys, the areas where two planes of the roof meet, are usually sloped. As a result, if these are not done properly or are cracked by being stepped on, rain water can penetrate inside as it flows over the roof. Which is enough to cause a roof leak.
