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 356 reviews Posted on Daniel JacobTrustindex verifies that the original source of the review is Google. GMT Chimney Services did an outstanding job installing a new liner in my chimney. Their price was nearly half of what other companies quoted, and the work was excellent. My chimney wasn’t drafting correctly, which caused my water heater to break. After the liner was installed, the issue was completely resolved. Highly recommend for their fantastic work!Posted on Gary SandersonTrustindex verifies that the original source of the review is Google. Outstanding service with Joe he was very helpful and I would recommend gmt and JoePosted on Kevin HealyTrustindex verifies that the original source of the review is Google.

I would absolutely use this company again and felt he went above and beyond to assist usPosted on josh aTrustindex verifies that the original source of the review is Google. 3.5 stars Not the worst not the best experience.. the guys that came and did inspection were great and knowledgeable, the guys that came and did the liner were also great.. Juan that came to check out my fireplace and put on the caps was excellent.. the guys that came and did the pointing, and outside work did ok work but didnt communicate with us... never rang doorbells or gave us calls, not good communication.... this comapny expect you to be home almost at all times says they will work with you in times so, scheduled a day to come work and needed someone to be home wife took day off and they tried to tell us no one was home didn't even knock or ring door bell... just left tried to tell us no one was home and that they rang door bell and knocked.. we have cameras and ring door bell and wife took day off.. one week goes by no calls nothing gave us 30 min notice called abut 9a.m to show up around 930... again the workers were all pretty good but the communication between them the lady in the office and home owners should be better.. she Called and asked for payment job wasn't complete.. caps were not install.. Juan came out again was great did what he had to do and bill was paid.. I'd love to use them again for a cleaning because the work was ok and some of the guys doing the work. But they need to realize that people work for a living and cant be home at all times and some of the workers and the office need to be able to communicate with the home owners and possibly each other a bit better.. the pricing was average better then some others and work was overall ok.. if your someone that can be home often this company will be perfect for youPosted on MariaTrustindex verifies that the original source of the review is Google.

Nice workPosted on Ravi GopieTrustindex verifies that the original source of the review is Google. Joe came to check my fireplace since I wanted to make sure I was good for the season before lighting it. He did a wonderful job of explaining that the fireplace was safe to use this year and advised me of when to contact them for a cleaning. He checked the firebox, and explained what was happening in the flue. I will certainly be calling GMT again for my future cleanings because of this interaction. Joe was friendly and warm, and did a great job explaining how to use the fireplace.Posted on אילן חרוביTrustindex verifies that the original source of the review is Google. Great service!
