Expert Flashing Seal Services in the Front Range

Stop the Moisture from Getting In!

Flashing sits at the base of the chimney and protects the gap where roofing meets the structure. When this area cracks or pulls away, water slides under the shingles and begins to soak the roof deck. Colorado weather puts heavy stress on this joint. Sun, snow, wind, and shifting temperatures slowly break down the protective materials.


We provide complete flashing seal service for homeowners and property managers. This includes sealing open seams, coating worn edges, reinforcing weak areas, and restoring the water barrier around the chimney base. The goal is to stop leaks before they spread. Once the barrier is strengthened, the roof can shed water the way it was designed to.


Many homeowners reach out after noticing stains near the chimney indoors or seeing shingles lifting at the base. Others schedule service as a preventative measure. Flashing issues often stay hidden until they cause major repairs. A proper flashing seal prevents that.

Why Your Flashing Seal Matters

Water Protection

Roof Preservation

Roof Preservation

Flashing is the primary defense against water entering the roof around the chimney. When gaps form, even small ones, water finds its way under the shingles. A fresh flash seal blocks these entry points and keeps the roof structure dry.

Roof Preservation

Roof Preservation

Roof Preservation

Moisture that slips under the chimney base softens wood, breaks down insulation, and increases the chance of rot. Over time, this weakens the entire roof section. Flashing seal work protects the home from this slow damage and extends the life of the roofing materials.

Long Term Safety

Roof Preservation

Long Term Safety

Water around the chimney area impacts both the roof and the structure that supports the fireplace. A strong seal creates a stable boundary that keeps moisture away from framing and prevents damage that can spread quietly over time.

Before You Call

Chimney base issues often show subtle signs. Ceiling marks appear near the chimney. Shingles start to curl or shift. Paint may bubble in the attic close to the chimney line. These signs suggest water is entering through failing flashing. A flashing seal service stops the problem before it grows.


If you see signs of water near the chimney or want to protect the roof before problems start, reach out. We can secure the chimney base and prevent moisture from entering the home.

What Happens if You Do Not Schedule a Flashing Seal

Leaks Spread Through the Roof

Leaks Spread Through the Roof

Leaks Spread Through the Roof

A ceiling that has water damage as a result of having a leaky roof.

Once water enters through a compromised flashing area, it travels along beams and framing. Damage may appear far from the actual entry point. A simple repair becomes much larger if ignored.

Mold and Rot

Leaks Spread Through the Roof

Leaks Spread Through the Roof

Mold growing on the side of a chimney.

Trapped moisture weakens wood and encourages mold growth. This affects indoor air quality and undermines the roof structure. A strong flashing seal prevents these hidden issues.

Damage to the Chimney Base

Leaks Spread Through the Roof

Damage to the Chimney Base

A damaged chimney base.

Moisture can soak siding, sheathing, and trim at the chimney base. When this continues unchecked, repairs become expensive. Flashing seal work protects these areas and prevents deterioration.

The cost of repairing your flashing seal is tailored to your specific roofing needs. Because the extent of the damage and the complexity of the repair can vary greatly, we first perform a thorough inspection, explain the required work in detail, and then provide a clear, no-obligation quote before any service begins.

A water damaged flashing.

A homeowner can watch for water stains, check the attic for damp spots, and keep the area free of debris. These steps help monitor the condition of the chimney base.

What a Technician Handles

A flashing prepared to be sealed on a home near Denver, CO.

A technician inspects the flashing, prepares the surface, removes failing sealant, applies professional grade materials, and reinforces the edges where water pressure is strongest. We also look for hidden moisture and damage around the chimney base. Proper flashing seal work requires knowledge of roofing materials and the chimney structure.

Frequently Asked Questions

Please reach out to owen@highpoint-hvac.com if you cannot find an answer to your question.

Once a year is recommended. The Front Range climate puts pressure on roofing joints, and small gaps form over time.


We clean the area, repair open seams, apply a new protective layer, and strengthen weak points around the chimney base. This restores the water barrier.


Temperature changes, roof movement, wind, and worn sealant all contribute to flashing breakdown. Homes in Colorado experience all of these.


Yes. Flashing problems often occur under the surface, and shingles may appear normal from above.


If the metal has warped, rusted, or pulled away from the chimney, sealing is not enough. A full flashing replacement may be the better choice. We explain this during inspection.
