Pipe Boot Failure:

One of the common roof leaks is pipe boot failure where the boot that is attached around the pipe fails to work. A boot is actually a type of roof flashing and goes around the base of pipes that comes out of your roof and waterproofs them. The various types of boot for a roofer are lead, copper and plastic. The main job of a roof is to stop water from the pipe into your room. Generally, the pipe boot lasts for 10 years but location and weather can decide how long it will last

Where does the leak show up?

Roofing Nails Backing out of Shingle:

Another common cause for leaks is when a roofing nail backs out of a single. This can happen with both air- nailed or hand nailed. Generally, if a nail is not driven enough sideways it causes the head of the nail to back out of the shingle. Now when it starts raining the water catches the head and comes down to your rood falling the nail inside. Not only on roofing nails but it also happens on decking nails. If you find any nail sticking up on your roof there are high chances that there will be a leak.

In order to repair the leak, you have to break the shingle, lift the shingle, pull the nail and move it. Now if the nail wasn’t driven properly, then you have to pull it out, drive it in properly, lay some ice and water shield above it. After the nail has been driven through the shingle, then the shingle is again resealed. If you find that the decking nail has not hit the wood, then the nail needs to be moved so as to catch the rafter. After this, the nail hole is filled with cement and the shingle is resealed.


Debris clogging gutters that stop above a roof-line under a valley

A valley is a place where two roof meets in a V shape thereby allowing the water to flow down a roof freely. When a valley stops in the middle of the roof it will have a gutter so that the water can continue flowing down. Generally, the problem happens with the fascia, the fascia is the board that runs along the edge of the roof carrying all the gutters. Such a leak doesn’t happen in normal circumstances. It happens when there is an extreme downpour and the gutter gets filled with debris and leaves it sends the water through the path of resistance. When the water gets to the soffit which is the underside of the lower edge of a sloped roof, behind the gutter, the water can travel anywhere causing great damages

Wear and Tear of Chimney

Generally, when it rains heavily for some days the bricks and mortar joints get saturated.

Sometimes your chimney can be leaking if the masonry top is cracked due to being wet and freezing. In a chimney siding, the water can travel to the corners thereby rotting the boards.

Collar Failure around a gas vent

The gas vent is a metal pipe with a cap coming out of the roof. It is another common roof leak spot. These are extremely important as it makes sure that any carbon monoxide coming out from gas appliances is vented out through the roof. Generally, leaks don’t happen around it however if there is heavy downpour water can splash under the collar and lead to water running down the pipe
