Keep Water Out of Your Flue

Chimney Rain Cap Installation

A rain cap covers the flue opening to keep rain and snow, along with animals and debris, out of your chimney. Without one, water gets into the flue and causes rust, leaks, and interior damage over time. We measure your flue and securely mount a properly fitted, weather-resistant cap that protects the opening while maintaining proper airflow and draft.

Why a Rain Cap Is Important

Without a cap, water enters the flue and causes rust, leaks, and costly interior damage.

An open flue is a direct path for rain and moisture to enter the heart of your chimney. Every storm sends water down into the flue, where it rusts the damper and metal components, soaks the masonry, and works its way toward the firebox and surrounding structure. Over time this leads to rust, leaks, deterioration, and expensive interior repairs, and an open flue also invites birds and animals to nest inside. A properly sized rain cap solves all of this at once. It covers the flue opening to block rain, snow, animals, and debris, while its design maintains the airflow your chimney needs to draft correctly. Installing a rain cap is a small, inexpensive step that prevents a long list of costly problems.
