Do you find a dread brown spot on your ceiling? Water is the most common cause of ceilings damage, eventually leading to ugly brown spots. Whether caused by a broken shingle or a faulty pipe, water leaks in your roof can wreak havoc on your home. The good news is that most roof leaks are relatively easy to fix and won’t require a major repair project.

In this guide, we’ll show you some of the most common roof leaks and how to repair them. We’ll also provide some tips on how to prevent roof leaks in the future.

Most Common Roof Leaks

There are two main roof leaks: surface leaks and structural leaks. Surface leaks are usually caused by damaged shingles or flashing, while a damaged roof deck or trusses typically cause structural leaks.

Surface leaks are usually the easiest to repair, while structural leaks can be much more challenging to fix.

1. Pipe Boot Failure

Pipe boots are used to seal around pipes that penetrate your roof. Over time, the rubber seals around the pipe boots can degrade, allowing water to seep in and cause a leak.

The types of boots a roofer could use are lead, plastic, copper, and so on. The main objective of a pipe boot is to cease water from trailing the pipe down through your roof and into the home. They can become cracked over time due to different causes. Some of these include:

  • Harsh weather conditions (strong winds, hailstorms, heavy snowfall)
  • Physical damage (branches falling on the roof, people walking on the roof)
  • Age/wear and tear

When a pipe boot becomes cracked, water will enter through the crack and seep down into the home, causing water damage. To prevent this from happening, it is essential to regularly inspect your pipe boots and repair any cracks that may have formed.

  • There are a few different ways to repair a cracked pipe boot. One is to use a sealant such as silicone or urethane. This will fill in the crack and create a water-tight seal.
  • Rubber collar installation is a simple, fast, and effective way to repair any leaks in your home. It can flang around the old, cracked neoprene pipe boot and last you for another 10-15 years without any issue.
  • Another option is to replace the entire boot with a new one. This is usually only necessary if the boot is severely damaged or leaking in multiple places.

No matter which repair method you choose, fixing the problem as soon as possible is important to prevent further water damage to your home.

2. Leaking Skylights

Skylights are another common source of leaks. Over time, the sealant around the skylight can deteriorate, allowing water to seep in. The main reason is that the sealant is constantly exposed to the elements, which can cause it to break down over time. Also, it can be caused due to improper installation.

If you have a skylight that is leaking, then the first thing you need to do is find the source of the leak. Usually, the leak will be coming from the sealant around the skylight or the flashing.

If your skylight is leaking, then water will come down from wherever it is located in your home. Skylight leaks can be annoying and cause damage to your home if they are not fixed quickly. There are a few ways to fix a skylight leak yourself or hire a professional to do it for you.

  • To repair a skylight leak, you must take the cladding and flashing kit off. This exposes the area around the skylight so that you can access it.
  • Then, you will need to put an ice and water shield around the exposed area.
  • It will provide a watertight seal that will prevent water from leaking in.
  • Finally, you will need to put the flashing kit back on. This secures the new seal and prevents future leaks.

3. Improperly Driven Nails 

Another common source of leaks is improperly driven roofing nails. Over time, the nails can work loose and allow water to seep in. The main reason is that the nails are not driven into the proper location. Also, the nails may be too small or the wrong type of nail for the job.

Also, decking nails that have been driven into the wrong spot can cause leaks. If the nail misses the wood when it is driven in, then over time, the sun’s heat will cause the nail to expand. This can cause the shingle to lift; eventually, water will find its way underneath.

If you have a leak caused by improperly driven nails, then the first thing you need to do is find the source of the leak. Usually, the leak will be coming from around the missing shingles or siding of roofing materials.

  • Once you have found the source of the leak, you will need to remove the old nails and drive new ones into the proper location. Using the correct size and type of nails is essential to prevent future leaks.
  • Breaking the shingle seal is the first step in repairing a decking nail leak. The roofer will need to lift the shingle to access the nail.
  • Pulling the nail out may be necessary if it wasn’t driven in straight. If the nail has worked its way through the shingle, then the shingle will need to be resealed.
  • If the decking nail didn’t hit the wood, then the roofer will fill the nail hole with cement and reseal the shingle.

4. Leaking Gutters

Gutter issues are common and can be easily fixed. The problem happens when there’s no flashing applied to the fascia board, which is the board that runs along the lower edge of the roof that carries all the gutters. Without flashing, water can seep in and cause damage.

  • Gutter location will also help you determine where the water is coming in. If you have a flat roof, the water will likely come in at the seams of your roof.
  • To fix this, you’ll need to apply some flashing around the edges of the fascia board. You can either use metal flashing or install a new layer of asphalt shingles over the top of the board to create a seal. 
  • Once you’ve properly sealed up the fascia board, you should check your gutters to ensure they’re properly secured and not leaking. If they are, you can reseal them with some caulk or replace them entirely.

5. Chimney Wear And Tear

One of the most common areas for leaks is around the chimney. Due to its location on the roof, the chimney is constantly exposed to the elements, which can take its toll over time. Bricks and mortar can begin to erode, crack or crumble, leaving gaps for water to seep through. In addition, the flashing, the metal strips that seal the gaps between the chimney and roof, can also become damaged or dislodged, resulting in a leak.

If you suspect that your chimney is causing a roof leak, it’s essential to have it checked out as soon as possible by a professional.

  • If the leak comes from the flashing around the chimney, a roofer will simply go in and reflash the area around it.
  • Also, if the leak comes from the mortar joints, they’ll have to apply a masonry water repellent to seal it. In either case, repairing the leak should be a relatively straightforward process.

A roofing company can easily identify any damage and carry out repairs to prevent further leaking. So, be sure to contact us in case of emergency.

6. Collar Failure Around A Gas Vent Pipes

The metal or rubberized collar used to seal the gap between the pipe and the roof sometimes deteriorates. The caulking also dries out, cracks and shrinks over time. You can check for a gas vent pipe leak by looking for any of these symptoms:

  • A stream of bubbles comes up through the shingles
  • Shingles that are lifting away from the roof deck around the pipe
  • A telltale black stain on the ceiling below

To repair a roof vents pipe leak, you will need to:

  • Remove the old sealant and caulk from around the pipe with a putty knife or utility knife. Be sure to remove all of the old material so that you have a clean surface to work with.
  • Apply a generous amount of roofing cement or sealant around the pipe, making sure to fill in any gaps.
  • Please place a new metal or rubberized collar over the pipe and press it into the roofing cement.
  • Secure the collar in place with screws or nails.

Do You Need a Roofing Contractor To Repair Your Roof?
