Finding Alternatives to Grinding for Stone Chimney Flashing Installation on a Roof
As a resident of Maine or New Hampshire, you know how crucial it is to maintain your chimney's integrity, especially during the harsh winter months. One crucial aspect of this maintenance is ensuring proper flashing installation on your roof. However, when dealing with stone chimneys, grinding can be a significant challenge. In this blog, I'll guide you through finding alternatives to grinding for stone chimney flashing installation on a roof, providing you with the necessary steps, recommendations, and tips to ensure a successful and stress-free process.
For over 12 years, I’ve been helping homeowners in Maine and New Hampshire with their chimney service needs, and one of the most common questions I get is about chimney flashing installation. Flashing is a crucial component that prevents water leaks around the base of your chimney, and it’s especially important here in the North East where we experience harsh winters.
Traditionally, installing a new chimney flashing often involves grinding down the existing stone or brickwork to create a smooth surface for the flashing to adhere to. But what if you don’t want to alter the look of your chimney? Here, we’ll explore some alternative methods for installing chimney flashing without grinding.

Why Grinding Can Be a Problem
Grinding, which involves using a grinder to remove old mortar and debris from the chimney, can be a significant issue when dealing with stone chimneys. This is because stone is a porous material that can be easily damaged by the grinding process. Additionally, grinding can lead to further damage to the surrounding area, including the roof and the chimney itself. Moreover, grinding can:
- Damage the aesthetics: Grinding can leave behind a rough, uneven surface that may not match the surrounding stone or brickwork.
- Weaken the structure: Grinding can remove a small amount of material from the chimney, which could potentially weaken its structural integrity over time.
- Create a mess: Grinding creates a lot of dust and debris, and it can take several hours to complete the job properly.
Alternatives to Grinding for Chimney Flashing Installation
Fortunately, there are several alternatives to grinding that you can use for stone chimney flashing installation on a roof:
