The Different Types of Roof Leaks

A roof leak can be a major annoyance and cause water damage to your home or business. But what are the different types of roof leaks, and how do you go about fixing them?

This blog post will answer those questions and more! We’ll discuss common roofing problems that can lead to leaks, and provide tips on how to prevent and fix them. So if you’re dealing with a pesky roof leak, read on for some helpful advice!

Leaking Seams

One of the most common places for leaks to occur is at the seams. Seams are where two pieces of material join together, and over time they can loosen or separate, allowing water to seep through.

You may be able to see signs of a leaking seam by examining your roof for cracks or gaps. If you see any, it’s important to have them repaired as soon as possible to prevent further damage.

Leaking seams are usually caused by improper installation, but they can also be the result of wear and tear over time. If you’re not sure what’s causing your leaking seams, it’s best to call a professional for an inspection. They’ll be able to determine the cause and recommend the best course of action.

Leaking Chimneys

Chimneys are one of the most common sources of roof leaks. Water can enter the chimney through cracks or gaps in the brickwork or mortar, and then run down the inside of the chimney, causing damp patches to appear on the ceiling or walls. In some cases, the leak may be due to a faulty chimney liner or flashing.

Blistering Shingles

One type of roof leak is caused by blistering shingles. Blistering shingles are caused by trapped moisture between the layers of the shingle. This can be caused by several things including:

  • Improper installation of the shingles
  • Damaged or missing flashing
  • Poor ventilation
  • Rainfall or snowmelt seeping in through gaps in the shingles

If you notice any blistering on your shingles, it’s important to have a professional roofer take a look as soon as possible. Left unrepaired, blistering shingles can lead to more serious problems.

Dormer Leaks

Dormer leaks are one of the most common types of roof leaks. A dormer is a projecting structure built on the roof of a building, typically with a window, that allows light and air into the interior.

Dormers are often added to homes for aesthetic reasons, but they can also be functional, providing additional space and headroom. Because they project outward from the roof, dormers are especially susceptible to leaks.

One of the most common causes of dormer leaks is improper flashing. Flashing is the material (usually metal) that is used to seal the joints between the dormer and the rest of the roof. If the flashing is not installed correctly, water can seep in and cause leaks.

Another common cause of dormer leaks is damaged or missing shingles. Shingles can be damaged by severe weather, falling tree limbs, or simply age and wear. If there are any gaps or missing shingles, water can get in and cause leaks.


There are many different types of roof leaks, and each one requires a different approach to repair. If you’re dealing with a roof leak, it’s important to have it fixed as soon as possible to prevent further damage.
