Chimney Repair Services in Lynchburg, VA

Professional Chimney Repair in Central Virginia

Chimneys are one of the most vulnerable points on any roof. The junction between chimney and roof—protected by flashing—must withstand constant thermal movement, driving rain, and years of weathering. When chimney components fail, water infiltration can cause serious damage to your roof structure, attic, walls, and interior finishes. At Mapleton Roofing, we provide comprehensive chimney repair services that address flashing, caps, crowns, and masonry issues to keep your home dry and protected.

Chimney problems are among the most common causes of roof leaks. Water stains on ceilings near chimneys, musty odors, or visible deterioration of chimney components all signal that repairs are needed. Our experienced team identifies the source of problems and provides lasting solutions that protect your home for years to come.

Chimney Flashing Repair and Replacement

Chimney flashing is the metal barrier that seals the gap between your chimney and roof. Properly installed flashing prevents water from entering this vulnerable junction. When flashing fails, leaks are almost inevitable.

How Flashing Works: Quality chimney flashing consists of two components working together. Step flashing is woven into the shingles along the sides of the chimney, with each piece overlapping the one below. Counter flashing is embedded into the chimney mortar joints and overlaps the step flashing, creating a watertight seal that allows for movement between chimney and roof.

Common Flashing Problems: Flashing fails for various reasons including deteriorated sealant and caulk that hardens and cracks over time, corrosion of metal components especially in lower-quality materials, thermal movement breaking bonds between flashing and chimney, poor original installation lacking proper overlap and integration, and physical damage from storms or impacts.

Our Flashing Repair Process: For minor issues, we can reseal existing flashing with quality roofing sealants. When flashing is significantly deteriorated, we remove the old flashing completely, install new step flashing integrated properly with shingles, cut grooves in mortar joints for counter flashing, set and seal counter flashing for watertight protection, and inspect and repair any damage to surrounding shingles.

We use quality metal flashing—aluminum or lead-coated copper—and high-grade sealants that remain flexible and weather-resistant for years.

Chimney Cap Installation and Repair

Chimney caps (also called rain caps or spark arrestors) cover the top of your flue, preventing rain, snow, animals, and debris from entering while allowing smoke and gases to escape. A damaged or missing cap invites water directly into your chimney, where it damages the flue liner, deteriorates interior masonry, and can migrate into your home.

Benefits of Proper Chimney Caps: Quality caps prevent water infiltration that damages flue liners, keep animals (birds, squirrels, raccoons) from nesting in your chimney, stop downdrafts that can blow smoke into your home, arrest sparks that could ignite roof debris, and reduce moisture that contributes to masonry deterioration.

Our Cap Services: We install caps sized correctly for your flue, made from durable materials (stainless steel or copper) that resist corrosion. For existing caps, we assess condition and repair or replace as needed. We ensure proper fit and secure mounting to withstand wind loads.

Chimney Crown Repair

The chimney crown is the concrete or mortar cap that covers the top of the chimney around the flue. It sheds water away from the flue and protects the top courses of masonry. Crown problems are very common and often the source of water infiltration.

Crown Problems: Many chimneys have crowns that were improperly built from the start—too thin, lacking proper slope, or made from inadequate materials. Over time, crowns crack from freeze-thaw cycles, allowing water into the masonry below. Cracked or deteriorated crowns require repair before damage spreads.

Crown Repair Options: For minor cracks, we can apply flexible crown coating that seals cracks and prevents water entry. For significant damage, we remove the deteriorated crown and install a new one, properly sloped and made from appropriate materials. We ensure crowns overhang the chimney sides to direct water away from masonry.

Masonry and Tuckpointing Services

Brick and stone chimneys are durable, but the mortar between masonry units deteriorates over time. When mortar fails, water enters the chimney structure, accelerating deterioration and potentially causing structural issues. Tuckpointing (also called repointing) restores mortar joints to protect your chimney.

Signs of Mortar Deterioration: Look for gaps or voids in mortar joints, crumbling or sandy mortar that falls away when touched, white staining (efflorescence) indicating water migration, pieces of mortar on roof or ground below chimney, and visible cracks in mortar joints.

Our Tuckpointing Process: We carefully remove deteriorated mortar to appropriate depth (typically 3/4 inch or more), clean joints thoroughly to ensure good mortar adhesion, pack new mortar that matches the original in color and composition, tool joints for proper profile and weather resistance, and allow proper curing time for maximum durability.

For chimneys with extensive deterioration, we may recommend more comprehensive restoration or rebuilding of affected sections.

Additional Chimney Services

Cricket Installation: Chimneys on the downhill side of the roof can accumulate water and debris behind them. A cricket (also called a saddle) is a small peaked structure that diverts water around the chimney. If your chimney lacks a cricket and you're experiencing water issues, adding one can solve the problem.

Chimney Waterproofing: Brick absorbs water, which then freezes and causes spalling (surface breaking away). Waterproofing treatments allow vapor to escape while preventing liquid water from entering. This extends masonry life significantly in our freeze-thaw climate.

Structural Assessment: If your chimney is leaning, separating from your home, or showing signs of structural distress, we can assess the situation and recommend appropriate action, whether that's stabilization, rebuilding, or removal.

Chimney Problems and Roof Leaks

Many homeowners don't realize their roof leak originates at the chimney. Water entry around chimneys can travel along rafters and sheathing before appearing on ceilings, making the chimney source non-obvious. If you have water stains near your chimney or experience leaks primarily during wind-driven rain, chimney issues are a likely culprit.

During roof inspections, we always examine chimney condition carefully. Many leaks attributed to "roof problems" actually stem from flashing, crown, or masonry issues that are easily addressed once properly identified.

Chimney Repair During Roof Replacement

When you're having your roof replaced, it's the ideal time to address chimney issues. We always replace chimney flashing during roof replacement—reusing old flashing defeats the purpose of a new roof. We also assess cap, crown, and masonry condition at this time, allowing you to address everything at once rather than returning for chimney work later.
