Age of Roof:

The age of the roof is the primary factor that leads to roof leakage.

It is said that a roof would last good for nearly 25 years. When the age of the roof increases, then it might lead to roof leakage.

Due to continuous exposure to rain and sunlight, there are chances for deterioration of the roof.

This would make it easier for the water to enter inside the roof. Thus leakage on the older roof should be addressed with serious concern.

Damaged Shingles:

Shingles are the vital component of your roofing structure. There are chances for the shingles to be damaged by extreme temperature and harsh climatic conditions. Shingles can also be removed due to heavy wind.

Flashing Damage:

Presence of Holes

Flashing is nothing but a thin metal strip for sealing roof transitions. It acts as a water-resistant barrier under the shingles.

There are chances for the damage of the flashing, or it can get misplaced due to various reasons. This would result in leakage in roofs.

Debris in Gutters:

Gutters are the provisions for the outflow of rainwater. Collection of waste like leaves in the roof, can clog the gutters and prevent the flow of water into the drain.

Thus water remains stagnant on the surface of the roof. This may result in leakage. 


There are various penetration and installations in a roof. You have vent pipes, roof vents etc. which should be checked for cracks. These cracks can end up in leakage of the roof.

Roof Slope:

The slope of the roof is the crucial factor to avoid the collection of rainwater in the slope. Avoid shallow slope as it can misplace the shingles and water would seep into it.

Make sure to use the right material for roof pitch failing it would result in leakage.

Presence of Holes:

Ridge Cap

Inspect the roof frequently as there are chances of holes in the roof surface. Holes can be an underlying reason for drawing in water inside the roof.

Make sure that you seal unnecessary holes to avoid leakage.

Ridge Cap:

This is an element used to cover the gap between two slopes in a roof. There are chances for holes in the ridge cap when it is not installed correctly.

This would result in rainwater entering into the roof.


Moisture content is a significant threat to your roof. The presence of moisture in the roof for a long time is a serious issue, and it can result in roof leakage.

The above are some of the common reasons that cause roof leakage.
