Common Reasons Why Your Chimney Is Leaking

Every area of your roof needs to be sealed tightly to prevent water from seeping through. The chimney is one area of the roof prone to cracks and damage, which can allow water to enter the chimney area and leak into your home.

If your chimney is leaking, the best course of action is to contact a roofing contractor to assess and repair the issue. Read on to learn the most common reasons you may have a chimney leak. If you have a roof leak from your chimney, let Nelson Contracting provide you with a free inspection.

Missing or Damaged Chimney Cover

Your chimney is essentially an exposed tunnel that juts out of your roof. Without the proper covering on the top of the chimney, water and moisture can easily seep in.

Chimney covers (aka chimney caps) play other roles as well. These caps prevent leaves, sticks, and other debris from entering your chimney, which can cause a chimney obstruction and block smoke from leaving the chimney when you light a fire. An obstruction can cause carbon monoxide to enter your home, which can be extremely dangerous.

If you’re experiencing a chimney leak, we recommend first heading outside and looking at your chimney from the ground to identify whether your chimney has a cover. If your chimney has no cover, you must install one as soon as possible. If it does have a cover, the cover could be damaged or cracked, allowing water to enter.

Damaged Chimney Flashing

Chimney Flashing Leak

The chimney flashing is a sheet of metal surrounding the chimney that creates a seal between the chimney and the roof. Having durable, fully functioning chimney flashing is essential to prevent chimney leaks and water entry.

If your chimney flashing is old, damaged, or malfunctioning, you may notice leaking inside or outside the chimney. Here are a few signs your chimney flashing needs a repair:

  • You see discolored bricks near the flashing
  • Your ceiling has water stains or dark areas
  • You notice rust stains along the flashing
  • Your leak is occurring outside the firebox

Damaged Chimney Crown

The chimney crown is a large slab of concrete, metal, or stone that covers the entire opening to the chimney. This feature is larger than the chimney cap, protecting the entire brick-and-mortar chimney structure rather than just the chimney flue. It contains an overhang that acts as a rain gutter, diverting moisture from the chimney.

If your chimney crown is damaged, you may notice water leaking into the firebox or through the chimney flashing. Without the protection of the chimney crown, the bricks that make up your chimney may begin to deteriorate, allowing water to seep in.

Chimney crowns are custom-built to fit each chimney. As a result, if your crown is damaged, you’ll need the help of a professional roofing company to repair it.

Damaged Brick and Mortar Joints

The exterior parts of chimneys are typically made up of bricks with layers of mortar joints between them. This chimney structure can deteriorate over time from precipitation and debris that pelt the roof. When the bricks and mortar joints deteriorate, a chimney leak can occur.

The longer you go without repairing the bricks and mortar joints, the more damage will occur. If you suspect that your bricks and mortar joints have begun deteriorating, you should call for a repair as soon as possible. We can perform chimney tuckpointing and waterproof the bricks to prevent further leaks.

Condensation Build Up

Sometimes, chimney leaks can occur when condensation builds up inside the fireplace. While this event is rare, it could be the culprit if you have exhausted all other chimney leak causes.

Gas fireplaces often give off fumes that produce moisture within the chimney. If your gas fireplace does not have the proper liner or the liner isn’t installed correctly, this moisture can seep through the chimney’s walls, eventually creating a leak.

Scheduling a chimney inspection can help you identify whether your liner is working correctly or another issue is causing your chimney leak.

Gutters Need To Be Removed

Do My Gutters Need to Be Removed Before a Roof Replacement

Gutters Need To Be Removed

If you’re considering replacing your roof, you may wonder: “Do my gutters need to be removed before a roof replacement?”

The short answer is not necessarily. The long answer is that it depends on the condition of your gutters and whether their placement would interfere with the roof installation.

Read on to learn more about gutters and roof replacements. Be sure to contact Nelson Contracting at 402-464-2418 to request your free roof replacement estimate. We service Lincoln, Omaha, and all surrounding cities.

Reasons to Remove Gutters Before Roof Replacement

Roof Replacement

Many roofing contractors will tell you that replacing a roof without removing the gutters is impossible. In reality, it’s not necessarily impossible — but it can be tricky depending on the roof design.

However, if you’re in a position where you don’t mind removing the gutters before the roof replacement, doing so can be helpful. Here are a few reasons to remove gutters before the roof replacement:

  • Allow for easy access to the entire roof: Gutters are often connected directly to the roof. As a result, your roofers may need to remove them in order to remove the sections of the roof attached to the gutters. Removing the gutters may also be necessary to install ice and water shields or other accessories on the roof.
  • Prevent gutter damage: If you decide to keep your gutters on during the roof replacement, they could quickly become damaged during the construction. Damage can occur while tearing off old shingles or carrying roofing materials onto the roof.
  • Ensure proper gutter installation: If your roofers attempt to work around your existing gutters, they may not align correctly with the new roof pitch or design. Removing the gutters and re-installing them after the roof replacement can ensure a better fit.
  • Replace gutters at the best possible time: If your gutters show signs of wear and tear or are older than 20 years, a roof replacement can give you an excellent excuse to replace them.

Can You Wait to Replace Gutters After Roof the Replacement?

If you would rather not replace the gutters before the roof replacement for whatever reason, your roofing company should be able to work around this.

The best roofing companies know how to protect gutters during a roof replacement. They will take extra measures to secure your gutters, such as avoiding leaning ladders against the gutters and taking caution when laying the tiles on the roof edges.

After the roof replacement, your roofing company should blow debris out of the gutters during the clean-up process. You can then determine whether you want to keep the existing gutters or hire a gutter crew to replace them.

Can You Keep Your Existing Gutters When Getting a New Roof?

Perhaps the only reason to leave your gutters on during the entire roof replacement is that you just installed new gutters and do not want to purchase another set yet. If this is the case, your roofers may be able to keep your existing gutters during the roof installation.

However, if your gutters are attached directly to roof shingles or are too challenging to work around during the roofing process, your roofers may need you to remove them before they begin working.

Altogether, if you need new gutters and a new roof, we recommend completing both of these processes in conjunction to prevent your gutters from getting damaged during construction.

Other Things to Know About Roofing and Gutters

As you consider whether to remove your gutters before or after the roofing process or keep your existing gutters long-term, here are a few things to keep in mind:

  • Your gutters are an essential aspect of your roofing system. If they do not function properly, your new roof could become damaged.
  • Your gutters require routine maintenance and cleaning to remain in the best condition. If you decide to keep your existing gutters, be sure to clean them after the roof replacement if your roofers don’t clean them for you.

Altogether, if you’re wondering, “Do my gutters need to be removed before a roof replacement?” we can help. Contact our Nelson Contracting team today at 402-464-2418 to schedule a roof inspection or estimate for roof replacement in Lincoln or Omaha, NE.
