What Causes Leaks During Severe Wind and Rain?
While there are many causes for a roof leak, they typically show up when the rain is pouring down. Small showers don’t seem to always leak either because simply not enough water has leaked into the home to get to a level where it can be seen, or the roof leak only occurs when it is severely raining and the wind is blowing. Here are some reasons why your roof may be leaking:
Your Skylight is Damaged
As with any type of roof penetration, there is a chance for a roof leak. Skylights are especially vulnerable to leaks due to their location and the fact that they are exposed to the elements. If your skylight is cracked or broken, it can be a source of your roof leaking. Since the skylight has seals around them heavy rain can remain on those seals longer which can create the problem with water leaking in.
Clogged Gutters
Gutters play an important role in keeping your roof dry by directing rainwater away from your home. If your gutters become clogged with leaves and debris, they won’t be able to do their job properly. This can cause water to back up onto your roof, leading to leaks. During colder months of the year in areas that have freezing temperatures this can create another problem known as a roof ice dam. Roof ice dams can lead to roof leaks as well.
Damaged or Missing Shingles
Shingles are the first line of defense against rainwater. If your shingles are damaged or missing, it’s much easier for water to penetrate your roof and cause a leak. Since shingles can become damaged during high winds, it can make a roof especially problematic with rain and wind. Wind can also cause shingles to bend upward which allows water underneath the shingle. When this happens, it can lead to a roof leak. What’s worse is when you look at the roof later the shingle is laying back down in place which can make locating the roof leak a problem.
Chimney issues
Chimneys can be a source of roof leaks as well. If the flashing around the chimney is not properly sealed, water can get in and cause a leak. Additionally, if the chimney is cracked or damaged, it can also lead to a roof leak. Over time the seal around the chimney can become cracked over time which allows the roof leak to happen.
Sometimes simply apply roof cement will stop the chimney leak while other times the entire flashing would need to be replaced to stop the roof leak. If the roof only leaks during heavy rains and wind then chances are the flashing is damaged further up the chimney rather than level with the roof surface.
Pipe boot failure
Pipe boots are the rubber or plastic boots that go around pipes that penetrate your roof for air vents usually. These boots can sometimes be known as vent pipe flashing. They are designed to keep water from entering the home around where those pipes go through the roofing surface. If the pipe boot becomes cracked or damaged, it can lead to a roof leak. Since most of these boots are made of plastic and rubber they can crack over time which ends up causing a roof leak.
Damaged roof flashing
Flashing is a thin metal material that is used to seal the joints between different roofing materials. It helps to keep water out of those joints and prevents leaks. If your flashing is damaged or missing, it can be a source of your roof leaking. Damaged flashing can allow water to penetrate the roof and cause a leak. This can happen due to high winds, hail, or other weather.
Most flashing is located in key areas of the roof which are prone to having problems. Around chimneys, in valleys, etc. are common places to have flashing installed. There are different materials used for flashing including aluminum, copper, and even plastic. Strong winds and hail can cause flashing to crack and leak.
Sitting debris in roof valleys
Roof valleys are areas of the roof where two planes meet, creating a V-shape. These areas can be prone to collecting debris such as leaves and twigs, which can lead to roof leaks in heavy rain. When debris sits in the valley, it can block water from flowing off the roof properly. This can cause water to back up onto the roof and eventually seep into your home. If the debris sits long enough it can also cause dark spots and discoloration and damage the shingles on your roof which can decrease your home’s curb appeal and value. It’s important to properly maintain your roof and inspect it regularly clearing any debris from the roof and cutting back any branches or tree limbs. Lack of roof maintenance is one of the biggest problems for property owners when it comes to a roof leak and water damage.
Metal corrosion
Metal roofs are becoming more popular due to their durability and longevity. However, metal roofs can be prone to corrosion which can lead to roof leaks in heavy rain. Corrosion occurs when the metal is exposed to moisture for an extended period of time. This can cause the metal to rust and weaken, leading to a roof leak. If you have a metal roof, it’s important to inspect it regularly for signs of corrosion. If you do find any, it’s important to repair or replace the affected area as soon as possible to prevent further damage. Sometimes you may need to get a complete roof replacement to remedy the problem.
Horizontal rain and heavy winds can put your roof to the test
The older your roof gets the less likely it will protect your home from strong and severe storms which have heavy rainfall. Asphalt shingle roofs are the most susceptible when they get older as well. Since the rain doesn’t strike the roof at a downward angle it can get under roof shingles and cause water damage to the roof. The more pitch the roof has the less likely it will cause a problem. Flat roofs typically don’t have this problem as well. This can also be why you intermittent roof leaks as well if it’s caused by horizontal rain.
What Should You Do if Your Roof Leaks in Heavy Rain?
Now that you know some of the common problems and reasons for roof leaks during strong winds and heavy rainfall, what can you do about it? Whether it is a sporadic roof leak or a constant rain leak, here are some tips to help.
Find the source of the roof leak (it could be a plumbing issue)
It’s important to understand just when the roof leaks. There are typically plumbing pipes as well as HVAC ducts which can make it look as if the roof is leaking when there is actually a plumbing problem causing the water leak. On some roofing with drains that handle roof water there could be a leak so don’t discount plumbing problems before you understand where the leak is located.
If you have a roof leak during heavy rain, it’s important to find the source of the leak. This can be done by inspecting your roof for any signs of damage such as missing shingles, cracked flashing, or corroded metal. You may also want to check around chimneys and other areas where water could enter your home. The best place to start looking is the attic of the home looking for wet spots in the attic. If you have a roof leak chances are that the attic is the first place it will show up. Look for signs of your roof leaking and note where it is in relation to the exterior portion of the roof.
It’s not advised to go on your roof yourself to look for leaks. Instead look at the roof using a drone or binoculars. And if you need to get a roof inspection by a qualified roofing contractor. This is especially true during winter months or if you have metal roofing installed on your home. It’s best to leave this task to a professional roofing company for roof leak repair.
Clear the area where the roof leak is located
Once you have identified the source of the roof leak and roof damage, it’s important to clear the area in your home where the leak is located. This can help to prevent further damage and make it easier for a roofing contractor to repair the issue. If there is a chance for more rain make sure the area in your home is cleared as well including any electronics, furniture, or rugs to prevent further damages.
Try to contain the water leaking from the ceiling
If you have identified the source of the leak and cleared the area, it’s important to try to contain the water until the roofing issues are resolved. This can be done by placing buckets or tarps underneath the leak to catch any water that may be dripping. If possible, turn off any electricity in the area as well to prevent any potential hazards. You should also open windows and doors in the room to help with ventilation and drying the home once it stops raining. If you have a humidifier in your HVAC system it’s best to turn it down until the issue is resolved.
Call the roofing professionals to repair your leaky roof
If you have identified the source of the roof leak and tried to contain it, it’s important to call a professional roofing contractor. A qualified roofer will be able to assess the damage and provide you with an estimate for repairs. They can also advise you on any preventative measures that may need to be taken in order to avoid future leaks. It’s important to hire a reputable contractor who has experience in dealing with the type of roof you have installed and can provide you with a warranty on their work. Remember proper roof maintenance is the best way to prevent roof leaks on your property and prevent major damage from water leaking into your home.
