Why you need a chimney cap, who should install it, and how to take care of it. Now we want to share that knowledge with you.

Let's get started.

What is a Chimney Cap?

 

A chimney cap is a protective cover that sits on top of your chimney chase. This is made of strong materials like aluminum, steel, or galvalume. It stops rain, animals, and debris while letting air flow.

The cap prevents sparks from reaching the roof or flammable materials, reducing the risk of fire. Some chimney caps are designed with features that improve the draft, making your fireplace work better. Simple as that!

What is a Chimney Windscreen?

 

A chimney windscreen is a decorative metal screen designed to protect your chimney from downdrafts caused by wind. The chimney cover has a base that fits over the top and sides encased by a screen. It blocks wind but lets smoke and gases escape safely.

Most windscreens are fabricated using standing seam metal roofing. A windscreen is not mandatory but can help with architectural design and hide the spark arrestor.

Who Has the Right Skills to Install Chimney Caps?

 

To install a chimney cap, it's important to hire professionals who can do it safely. For repairs, replacements, or new installations choose an experienced contractor. Below are the professionals who are well equipped to handle chimney cap installations:

  1. Roofing Contractors: Roofing contractors are often the go-to professionals for chimney cap installations. Being adept at working at heights and possessing extensive knowledge of waterproofing. They can integrate chimney cap work with roofing tasks, ensuring all components work and keep the rain out.
  2. Chimney Sweeps: Certified chimney sweeps are not only experts in cleaning chimneys but also proficient in tasks like repairing or replacing chimney caps. Leveraging their knowledge of chimneys, they can also conduct inspections and identify any underlying issues that might need attention.
  3. Handyman Services: Some handymen have the experience to handle a range of home repair tasks, including chimney cap installations. It's important to verify their experience with roofing and chimney work.
  4. Masonry Contractors: For chimneys constructed of brick or stone, masonry contractors are the ideal choice. Their specialized skills enable them to address both chimney cap installations and any structural issues with the chimney itself, ensuring longevity and optimal performance.
  5. Specialized Chimney Repair Companies: Some companies specialize only in chimney-related services, offering expertise in all aspects of chimney maintenance, including cap repairs and installations.

Choosing the Right Professional

When selecting a professional, ensure they are:

  • Licensed and insured for chimney work.
  • Experienced with your specific type of chimney and cap.
  • Equipped with the right safety gear for working at heights, off ladders, or scaffolding equipment.

Crafting the Perfect Fit: The Custom Nature of Chimney Caps

 

When it comes to the world of chimney caps, there's no one-size-fits-all solution. Given that every chimney chase is uniquely crafted, a 'standard cap' doesn't exist in the realm of chimney cap replacement. Chimney chases have a special quality that requires careful measuring and making of chimney caps. Each cap must fit perfectly on its chimney.

RoofCrafters has been replacing chimney caps for more than 30 years. As we traveled across many rooftops, we learned that each chimney cap must fit the chimney it protects. Chimney caps are custom-made to fit and match the unique style of each chimney. This ensures both functionality and aesthetics.

In our experience, we’ve learned that attempting to fit a standard cap to a custom-built chimney is akin to trying to fit a square peg into a round hole. It won’t work. We measure every chimney and make a custom cap to fit perfectly and protect from weather.

Getting Down to Business: How Chimney Caps are Installed

 

Installing a chimney cap isn’t about finesse—it’s about getting the job done right, with accuracy and reliability. Professionals have the knowledge and skills for a secure and proper installation. Here’s the no-nonsense breakdown of how it’s done:

Step 1: Inspection and Measurement

First off, the professional needs to inspect the chimney and take the right measurements. This step is crucial because it ensures that the cap will fit.

Step 2: Custom Fabrication

After getting the precise dimensions, we move to the next stage, but installation doesn’t happen yet. Before anything else, the metal has to be custom-fabricated to fit your chimney chase. A custom ring and storm collar are also fabricated to keep the rain out.

Step 3: Installing the Cap

With the chimney cap in hand, it’s time to attach the cap to the chimney top or chase. It’s important to attach it and seal any joints or seams to avoid any leaks. This step is about making sure the cap is going to stay in place and do its job, keeping out rain, animals, and anything else that shouldn’t be in the chimney.

Step 4.: Final Inspection

Before completion, a final check is conducted for a secure cap, proper ventilation, and solid installation. This final look is about confirming that everything is in place and working as it should.

Straightforward and Essential

Installing a chimney cap is straightforward, but it’s essential to get it right. It’s about practical steps and accurate, reliable work. And that’s what professionals bring to the table. We ensure that we install your chimney cap right to protect your home.

Why Professional Chimney Cap Installation is Crucial

Installing a chimney cap may seem simple, but it requires precision and expertise. We want everything in the installation to fit together well, from the fittings to the ventilation. Experts have the knowledge and dedication to make the installation a work of art. They guarantee that your chimney cap keeps your home safe and brings you peace of mind while you enjoy cozy fires.

The Bottom Line: Evaluating the Cost

 

Installing a chimney cap is an investment in your home. On average, you can expect to spend between $1,500 and $2,500. Prices can increase for chimneys that are complex and positioned high off the roofline. As these chimneys may need extra safety measures and equipment. At first, it may seem expensive, but it protects against damage and saves on repairs.
