Your roof may occasionally experience intermittent leaks, which may lead you asking “why does my roof only leaks sometimes?” This is normal because when we think of a leaky roof, what usually comes to our mind is water continuously dripping from the roof through your ceiling. While this may be the case most of the time, there are also instances where the roof leaks are intermittent. And there are several reasons why.
In this blog post, we’ll discuss some of these reasons. This way, you’ll know what to do to address these intermittent roof leaks and prevent them from causing significant damage to your roof and home in general.

Damaged roof
If your roof’s leak is intermittent, it might be because your roof has been damaged by either hail, storm, or strong winds. While other roofs are designed to withstand extreme weather conditions, there are also others that are less weather resistant and are more vulnerable to damage. In such a case, it is highly recommended that you call a reliable roofing contractor right away and arrange for an inspection to determine the extent of the damage and prevent them from causing leaks.
Horizontal or windy rain
From the name itself, this pertains to the type of rain that runs horizontally rather than vertically. This usually happens when heavy rains are combined with strong winds allowing water to seep through the inside of your roof. Keep in mind that water is supposed to hit your roof at a 90-degree angle and then run off. If the rain falls parallel to the roof, instead of running off and draining to your gutters, water can easily enter the interiors of your home causing significant damage.
Heavy rains
If you ask “why does my roof leak,” the sheer amount of rain in your area can also be the answer. Normally, the rain runs off directly from the roof and drains through the gutters, away from your house. However, with heavy rains, your gutter might not be able to keep up. The water may become stagnant and end up seeping through the inside of your roof causing intermittent leaks.
Ridge vents
If you have ridge vents, a type of vent installed at the peak of a sloped roof to allow air to escape the building, then your roof may also be more susceptible to leaks. While vents are generally designed to prevent water from entering the interiors of the building, some types are not as water-resistant as the others (especially if the vents’ initial installation was done poorly). This means that they are less effective in waterproofing the roof to keep water out.
Chimneys
Another possible reason for the intermittent leak in your roof involves chimneys. Just like the other parts of your roof, chimneys should also be checked periodically since some of them may have been installed poorly, are old and rusted, or may already have cracks as a result of the constant expanding and contracting caused by the heat difference between the fireplace and the cooler external temperature. Any of these three makes the chimney more susceptible to leaks that may cause more damage to your home in general.
