Chimney flashing takes a beating where the flue meets the roof. Heat cycles from the flue, sun, rain and wind work the metal year after year, and once the factory finish fails the rust starts. A fresh coat of the right paint seals the metal and blends the flashing into the roof. The best paint for chimney flashing is one rated for the heat it will see, made to stick to metal, and matched to your roof. This guide compares each paint by what its listing states: temperature rating, finish, size, coverage and warranty.
Paint is the smallest cost in the job and the part most people skip. The listings below were picked because they state what matters for flashing: a temperature rating, a metal-compatible formula, and a stated coverage. The scores rank them for a working chimney, where heat and weather hit the same piece of metal.

Buying guide: choosing the best paint for chimney flashing
Heat rating
Chimney flashing sits against a working flue, so a stated heat rating is the first thing to check. The Rutland is rated to 1400°F, the highest here, while the Seymour and the NADAMOO are rated to 1200°F. The Seymour’s 1200°F is a continuous rating, meaning the listing claims it holds that temperature in steady use. The Geocel is made for shingle and flashing but states no heat figure, which is its main gap for a hot chimney. Match the rating to the flue, and trust only the number the listing states, never a rule of thumb. Heat is only half the job; the Rutland also claims 1 year of UV resistance, since flashing paint faces the sun as well as the flue.
Finish and color
Finish decides how the flashing looks against the roof. The Rutland is flat black, though its spec table calls the finish semi-gloss while the title and color code say flat black; we trust the title. The Seymour is matte aluminum, which suits bare metal flashing, the NADAMOO is matte black, and the Geocel is flat weathered wood, the only one here that blends with a shingle roof. A matte or flat finish hides brush and spray marks better than a gloss, which is why three of the four listings state matte or flat. See our chimney flashing for a metal roof guide for the flashing side of the job.
Brush-on or spray
The Rutland is a brush-on paint, which gives control around flashing edges and keeps paint off the shingles. The Seymour, NADAMOO and Geocel are sprays or aerosols, faster on broad flashing runs but needing the surrounding roof masked. The NADAMOO promises no brush marks, which only matters if you brush; with a spray, the equivalent concern is an even coat with no runs. For touch-ups and seams, brush-on wins; for a full flashing repaint, a spray is quicker.
Coverage
Coverage tells you how far a can goes. The Rutland covers 100 sq ft, the most here by far, enough for flashing and then some. The Geocel covers 25 sq ft per can, and the NADAMOO covers 10 to 12 sq ft per can for two light coats, the least here. The Seymour states that coverage depends on application, with no figure, so you cannot plan the job from its listing. Measure the flashing area before you buy, and remember the NADAMOO figure is for two light coats, not one.
Warranty
Only the Rutland states a warranty term with a length: 12 Month. The Geocel states a limited warranty with no term, and the Seymour and NADAMOO state no warranty term at all. A stated term is worth weighing, since flashing paint lives outdoors in heat and weather. Note that the Rutland’s 1 year of UV resistance is a separate claim from its 12-month warranty; the listing states both.
Wear eye protection and gloves for cutting, splitting and handling, follow every tool's manual, install stoves to code, and have the chimney inspected and cleaned every year. See EPA Burn Wise and NFPA heating safety. Read our Safety Disclaimer.
Around the Woodpile
- The Rutland needs no primer and sets without added heat, though the maker gets best results after exposure to heat; it dries in 3 hours.
- The Seymour sets fully in 2 hours and the Geocel dries in eight minutes or less, so plan recoats around the listing’s time.
- The NADAMOO is not for areas directly exposed to flames, such as grill grates or the inside of fireplaces, per its caution.
- The Rutland is listed as low VOC and the Seymour as VOC compliant, with no lead, cadmium, mercury, chromates or chlorinated solvents.
- The Geocel hides flaws, blemishes and unsightly roof protrusions, per its listing, so it doubles as a cosmetic touch-up for the flashing area.
Frequently Asked Questions
Can I use high-heat paint on chimney flashing?
Yes, if it is made for metal and rated for the heat. The Rutland is rated to 1400°F for metal and masonry, and the Seymour and NADAMOO are rated to 1200°F for metal surfaces. The Geocel is made for flashing but states no heat rating, so it suits a chimney that does not run hot. Always match the paint to the flashing metal and the flue, and prep the surface as the listing directs.
Do I need a primer before painting chimney flashing?
The Rutland states that no primer is needed. The other three listings do not address primer, so follow each listing’s own directions for surface prep. What every listing assumes is metal in sound condition before the paint goes on.
What color should chimney flashing paint be?
Match the roof or the flashing metal. The four paints here come in flat black, matte aluminum, matte black and flat weathered wood. Weathered wood blends with shingles, aluminum suits bare metal flashing, and black matches many flue pipes. The listing’s color is the only one you can count on.
How much paint covers chimney flashing?
It depends on the can. The Rutland covers 100 sq ft, the Geocel 25 sq ft per can, and the NADAMOO 10 to 12 sq ft per can for two light coats. The Seymour states that coverage depends on application, so plan for a second can if the flashing run is long. Measure the flashing before buying rather than guessing.
Can I spray paint flashing on the roof?
The Seymour, NADAMOO and Geocel are sprays or aerosols, and the Rutland is brush-on. A spray is faster on broad flashing, but mask the shingles and work on a calm day so overspray does not land on the roof. For seams and edges, the brush-on Rutland gives more control.
Will paint stop chimney flashing from rusting?
Paint is a barrier, not a rust remover. The NADAMOO states that it stops rust spread and shields against corrosion, and the Geocel states a rust-fighting finish that prevents stains. Both assume the metal is prepped first; paint over loose rust and the rust keeps going underneath. The Rutland and Seymour make no rust claims, so treat them as heat and weather coatings.
