At GMT Home Services, we know proper chimney flashing protects your home from water damage. Improper or damaged flashing around the chimney base and other roof penetrations can allow water infiltration, leading to costly repairs like wood rot, drywall damage, and weakened chimney mortar joints. Our experienced Connecticut team inspects, repairs, and installs flashing to keep your roof secure and your home safe.
A chimney is a major roof penetration, and existing flashing often deteriorates over time. Even minor cracks or gaps can allow moisture to slide under shingle courses and reach your roof deck. Proper flashing diverts water away from the vertical surface of your chimney, protects your walls, and ensures a watertight seal.
Signs it’s time for inspection or repair include:
Note: Ignoring these issues can cause water intrusion, leading to costly repairs over time.
Proper flashing involves more than just covering the chimney. At GMT Home Services, we ensure every flashing piece is measured, cut, and installed to create a watertight seal. Our team handles:
Every installation is aligned with roof slope, shingle courses, and minimum weight considerations, ensuring water is properly diverted down the roof and into gutters, preventing water intrusion.
Protect your home from snow, ice, and freezing rain. Our certified experts ensure proper flashing installation to prevent leaks, water infiltration, and damage caused by harsh winter weather.
A properly installed flashing system shields your roof from water infiltration at all critical points. Here’s how it works:
Combined with sealant or caulk, this system prevents leaks around roof penetrations, walls, and other roof openings. Proper flashing diverts water, protects your roof deck, and extends the life of both your chimney and shingles
The cost to replace chimney flashing depends on material, roof slope, and the complexity of the installation. Signs your flashing may need repair include:
Heavy CT rainfall can exploit weak flashing and roof penetrations. We inspect, repair, and install step flashing, base flashing, and cap flashing to divert water and maintain a watertight seal, safeguarding your home year-round.
Routine maintenance helps avoid water intrusion, reduces repair costs, and maintains your home’s structural integrity.
Sometimes, flashing cannot be repaired and requires full replacement. You may need a new flashing piece, cap, or step flashing if:
GMT Home Services ensures every new flashing installation is properly fastened, bent to fit corners, and sealed. We work with all types of roofs, including sloped, metal, and shingled roofs, to create long-lasting, watertight protection.
Installing chimney flashing requires skill, safety equipment, and attention to detail. Our team uses:
By combining experience and quality materials, we create a flashing system that diverts water, protects your chimney and walls, and ensures your home remains safe for years.
Strong winds and seasonal storms can lift shingles and compromise flashing. Our team uses high-quality materials and proper installation techniques to secure chimney flashing against shifting, cracks, and water intrusion.
Schedule your chimney flashing inspection, repair, or installation with GMT Home Services in Connecticut. Our certified roofing professionals ensure your home is safe, dry, and secure with proper flashing, watertight seals, and expert maintenance.
Chimney flashing is a metal barrier installed where the chimney meets the roof to prevent water infiltration. Proper flashing protects your roof deck, shingles, and chimney mortar joints, reducing the risk of costly repairs and structural damage.
Annual inspections by CSIA and NFPA-certified roofing professionals are recommended. Regular checks catch cracks, leaks, or rust early, ensuring a watertight seal and prolonging the life of your roof.
Look for water stains, leaks, rusted metal, loose flashing pieces, or damaged shingles near the chimney. These are indicators of water intrusion that requires professional repair or replacement.
Common materials include copper, aluminum, lead, and galvanized steel. Each material offers durability and protection, and your roofing professional will select the best option based on roof slope, shingles, and climate.
DIY flashing repair is not recommended. Proper flashing installation requires precision cutting, bending, and sealing to create a watertight seal. Certified technicians ensure safety and long-term protection.
Costs vary depending on materials, roof type, and labor. GMT Home Services provides transparent estimates after inspection, ensuring you only pay for what’s necessary to prevent water intrusion and protect your home.
Proper flashing directs water away from the chimney and roof deck, protects shingles, walls, and gutters, and prevents leaks and moisture that can lead to expensive repairs.
EXCELLENT Based on 365 reviews Posted on Google Colin PatersonTrustindex verifies that the original source of the review is Google. We had a great experience with Joe and team. Very responsive and thorough - he provided a detailed estimate on all the work needed to be done (we needed a complete rebuild from roofline). The team did a great job and are clearly very good at what they do. They were in and out in two days and their quote was beyond reasonable. Highly recommend.Posted on Google Joseph WendoverTrustindex verifies that the original source of the review is Google. I had a great experience with GMT Chimney Services. They were extremely responsive and able to come out quickly when I needed help after a bird got stuck in my chimney (thankfully it was fine!). They cleaned my gas fireplace, removed bird nesting and debris from the chimney pipe, and installed a new cover to prevent future issues. The team was professional, neat, and made sure everything was cleaned up before they left. Overall, they were easy to work with and did a thorough job. I would definitely recommend them to anyone needing chimney or fireplace services.Posted on Google Natasha SetschinskyTrustindex verifies that the original source of the review is Google.

The staff at GMT are professional, well educated, dog friendly, flexible with scheduling and ensure priority to jobs that need it. They use USA made products sourcing from the local community, offering lifetime warranties on most of their products, while also still maintaining very reasonable pricing. Their customers safety and satisfaction are first and foremost and it shows throughout their whole team. Joe came out on a Sunday for my estimate and by Friday of the same week I had my chimney lining replaced, everything detailed cleaned, and a new cap installed.Posted on Google Jackie RTrustindex verifies that the original source of the review is Google. Joe came to do an initial inspection for my fireplace/chimney and was very informative! I appreciate the time taken to explain the current state of my fireplace and recommendations!Posted on Google Jennifer GarciaTrustindex verifies that the original source of the review is Google. After searching for a chimney sweep company that were available to diagnose and repair before the inclement weather arrived, was extremely difficult. But GMT were able to arrive that same night. GMT estimated and fixed my whole situation before the snow touched the ground. I had an emergency situation with a roof replacement I previously had with another company gone bad. CO leaking in and unable to stay in my home. GMT secured the work done the very next day. My family and I were able to come back home after one night out. They were professional and fast in freezing temperatures. Town inspection passed. Service you can count on. Definitely reliable and compassionate. Highly recommend.Posted on Google Destinie MarieTrustindex verifies that the original source of the review is Google. Great experience overall.
