Cornerstone Chimneys

Identifies Hidden Hazards Caused by Storms and More

Oklahoma homeowners are accustomed to severe weather. Tornadoes, lightning storms, high winds, heavy rain, freezing temperatures, and even earthquakes are part of life here.

What many homeowners do not realize is that these same forces are constantly attacking one of the most exposed parts of the home: the chimney.

Because chimneys sit above the roofline, they take the full impact of Oklahoma weather year after year. Damage often begins small and hidden, but over time it can lead to water leaks, structural problems, or safety risks inside the home. Local experts and national safety organizations like the CSIA and NFPA recommend inspections at least once per year, even for chimneys that are rarely used. 

For four decades, Cornerstone Chimneys has helped homeowners identify and repair weather related chimney damage before it becomes a costly problem. The company is firefighter founded, veteran-owned, and built on safety. Founded by Fire Captain Wendell Evans and operated by firefighters and veterans, the company has specialized in chimney inspection, repair, and safety since 1979.

Cornerstone Chimneys in Tulsa is a licensed, and insured chimney service company featuring technicians with CSIA (Chimney Safety Institute of America) and NFI (National Fireplace Institute) certifications. They are recognized for HeatShield factory-trained expertise and professional, comprehensive inspections. Let’s break-down the offenders…

Lightning Damage to Chimneys

“Because the flue system runs inside the chimney, lightning damage is often not visible from the ground. Professional chimney inspections can identify hidden damage before it causes water intrusion or safety hazards,” explained Cornerstone Chimneys Lead Chimney Inspector Bob. He added, “One sign of damage is a smell like a barbeque grill in your fireplace. We use the latest camera technology equipment.” The inspector begins by inspecting your interior chimney and fireplace. The next step is the exterior inspection of your chimney and surrounding rooftop area. After the inspection is finalized, you receive a diagnostic report and estimate if repairs are needed.

Bob also said damage can include the sealant or the flashing can be compromised which would allow water to leak into your home. Additionally, water damage from hard rains with winds can slowly deteriorate your chimney flue pipe resulting in improper ventilation.

Tornadoes and High Winds Damage to Chimneys

High winds and flying debris can damage chimney caps, loosen flashing around the chimney base, and crack masonry structures. Tree limbs and storm debris can also strike chimneys directly.

Even when the damage appears minor, small openings can allow rainwater to enter the chimney system and begin damaging brick, mortar, and interior components.

Many storm related chimney repairs are covered by homeowners’ insurance, especially when the damage is caused by wind or debris.

Earthquakes and Structural Movement Damage to Chimneys

Oklahoma has experienced an increase in seismic activity in recent years. Even small tremors can affect masonry structures like chimneys.

Because chimneys are tall and rigid, ground movement can cause cracks in mortar joints or damage to flue liners inside the chimney system.

These small cracks can allow smoke, moisture, or combustion gases to escape into areas of the home where they should not be. A camera inspection inside the flue is often necessary to detect this type of hidden damage.

Water Intrusion Damage to Chimneys

Water is one of the most destructive forces affecting chimneys.

Without proper chimney caps, crowns, and flashing, rainwater can easily enter the chimney structure. Over time, moisture begins breaking down mortar joints, rusting metal components, and weakening brick.

Many homeowners first notice chimney leaks when they see stains on ceilings or walls near the fireplace.

By the time those signs appear, damage may already be occurring inside the chimney system.

Routine inspections and preventative maintenance can significantly extend the life of a chimney.

Freezing Temperatures Damage to Chimneys

Oklahoma winters bring repeated freeze and thaw cycles.

When water enters small cracks in masonry and freezes, it expands. This expansion slowly forces bricks and mortar apart.
