Chimney Repair is Hard

The very first thing that springs to mind in predicaments such as this is, “You Don’t Know What You Don’t Know,” and I have to admit that I was guilty of this when I was a very young contractor. There are occasions when this is beneficial since it allows you to have a heightened sense of confidence. You have a pattern of ignoring the possibility of failing or experiencing a negative outcome.

Let’s take a look at the project involving the chimney. To get things started, may I ask how you plan to work on the chimney? No difficulty at all if you have a straightforward ranch house with a roof that has a modest slope, such as the house where my father-in-law used to live, and if the chimney is located in an area where you can easily stand next to it. But what about roofs that are steeper?

Scaffolding of a certain kind is required for chimney repair. It is utilized by organizations that specialize in chimney restoration to construct work platforms on all four sides of a chimney. In order to put up this scaffolding in a safe manner, expertise is required. There is no room for optimism in this situation. When you load the work platforms with hundreds of pounds of brick and buckets of mortar, the scaffolding’s dynamics shift in a way that makes it more difficult to maneuver.

Due to the fact that the top three to four feet of your chimney have been degraded, you will need to dismantle it. You need to be able to salvage the brick and examine it to see whether or not it is damaged. The same may be said for the liners of the flue.

As is the case with any brick wall that is open to the weather, the mortar will eventually deteriorate and develop cracks while also losing parts of itself over time. In the event that this occurs, you will be required to repoint it. The objective here is to locate the areas in which the mortar has been sufficiently damaged and/or is missing, and then to prepare new mortar so that it may be used in those areas. Find the appropriate kind of mortar, and then mix it in accordance with the directions provided by the manufacturer. The next step is to fill the joints using a mortar bag and a trowel.

In this situation, the most important thing to keep in mind is that you need to remove all of the old mortar. You can’t just shove a glob of fresh mortar into a hole when it seems like part of the old mortar has disappeared, for example. That will result in a connection that is prepared for more failure in the not too distant future. Instead, remove all of the old mortar by grinding it down or chipping it away with a chisel, cleaning the hole with a wire brush, and then adding the new mortar.

You Have an Issue with the Flashing
Flashing is the material that prevents water from entering through the opening in the roof created by the chimney. It is pushed into the bricks with one end, while the other end is tucked beneath the shingles with the other end. In the event that it is broken or separates from one of the two, water will be able to enter.

Because it involves substantial work on both the brickwork and the roof, this is the most difficult external repair that a homeowner should generally contemplate. To paint a broad picture: Flashing is typically made of sheet metal and consists of two parts: the base flashing, which tucks under shingles on one end and nestles against brick on the other; and the cap flashing, which secures into a groove you’ve cut in the mortar and covers the top of the base flashing. Both parts of the flashing work together to ensure that water does not get behind the shingles or behind the brick. Therefore, you will need to cut and bend base flashing in order to line the bottom of the chimney, get it in place underneath the shingles, then grind out a groove around the chimney (stepping up the rows of bricks along the sides), and last, cut and install cap flashing.

Take another look at those specific instructions. There are many different things that may go wrong. Pay attention to the mortar, pay attention to the shingles, and most importantly, pay attention to the orientation of the bends and overlaps so that they truly shed water.
