5 Steps to Install a Chimney Cap

It’s important to install a chimney cap carefully so that you don’t damage your chimney. To make your job easier, here we have laid out some easy steps, let’s check them out!

Step 1: Prepare Things First

The very first thing you need to do is to get onto the roof using a ladder. Make sure the ladder extends 3 feet above the roof, it will let you climb safely. And, climb very carefully as you don’t lose your balance somehow.

Step 2: Go Through the Measurement Process

Now, you need to find the flue (a metal or clay tube) on your chimney. Generally, it extends out from the top of the chimney. Measure the length and width of the flue using a tape measure.

Don’t take risks of forgetting the numbers, better write down the measurements.

And, point to be noted, in case you have a circular flue, measure the diameter rather than finding the length and width. And, in case, there are multiple flues in your chimney, then use a top-mount cap.

Step 3: Purchase the Right-Sized Cap

You need to make sure that the cap has the same width and length as the chimney’s flue.

Chimney caps are totally available at hardware stores, so you’ll find one easily.

Remember, a flue that is made of galvanized steel will allow your chimney to have the most protection. So, try to choose one like this.

And, there’s nothing to worry about if you find the cap dimension is 0.5-1 inch larger than the flue, it will fit somehow.

But larger than 0.5-1 inch may not fit properly, so be careful.

Step 4: Place the Cap Over the Top of the Flue

Now, you are going to install the chimney cap. Firstly, line up the bottom of that cap with the top of the chimney flue. Gently lower the cap on the flue as well as push it down, let it go as far as possible.

Check if there is a minimum of 6 inches between the flue opening and the top part of the cap. Otherwise, the gases and smoke will not be able to vent completely.

Keep in mind that the cap will come with a rim around its bottom. This means you don’t have to place it too low on your flue.

Some of the circular chimney caps don’t fit around outside, they fit perfectly inside the flue. You better push the cap inside the flue and make it feel tight against the sides.

Step 5: Secure the Cap’s Screw Properly

Are you afraid of drilling any pilot holes? Well, don’t be. Because all of the chimney caps come with self-tapping screws. However, you need to feed the screws through every hole in the sides or corners of your cap.

Then, turn them clockwise simply using your hand and dig into the flue. Continue tightening the screws using a screwdriver and make sure the cap isn’t moving or shifting.

Voila! You’re done!

Before you go to repair the chimney cap, there are a few things to do as manual labor. Go carefully on the top of your top and spread a tarp under the area you are going to work. It will keep you from damaging other parts of the roof while repairing your chimney cap.

Step 2: Pull Out the Cap

Now, it’s time to remove the cap or crown whatever you say. Gently get the broken cap away from the chimney using a chisel and hammer. Remember to start from the outside.

Also, be careful so you don’t damage anything near the flue.

Use water and a scrub brush to remove any dirt or algae around the crown of your chimney. Also, look if there’s any crack you need to fix.

Step 3: Make a Stiff Crown Mixture

You need to apply a crown sealant to seal any crack or the broken part of your chimney crown. To make a stiff crown mixture, combine water and powdered mortar in a tray.
