Before & After Stone Coating

A Small Detail With a Remarkable Difference

Every roof has metal coming through it: plumbing vents, pipe jacks, heat pipes, attic vents, valleys, skylight flashings. On a lot of jobs that metal goes up bare galvanized or primed, and the finish is whatever comes out of a spray can. Spray paint is prone to deteriorate, and a shiny pipe sticking out of a brand new roof is the first thing the eye finds.

Stone coating takes care of the part everyone notices. Our flashings and vents carry a stone coated finish in your roof color, so those unsightly pieces blend in and complement the roof instead of fighting it. Put a bare galvanized vent next to the same vent stone coated and the before and after says it all: no leaks, no chipping, no fading. It is a small part of the whole roof, and it is the part that makes a roof look finished.

Stone Coated Flashings, Vents and the Rapid Sleeve

All products

Stone coated flashings cover plumbers, assemblies, valleys, O'Hagins, nosing, roof to wall, saddles, skylights, steep flashings and specialty flashings, and roof jack flashings are our specialty. On pipe flashings we seal the seam on the cone with an adhesive that bonds with the metal, because that seam is where so many of them leak.

Stone coated vents bring the same finish to the vents a roof needs, from low profile O'Hagin vents to dormer vents, elbow vents and double wall vent pipe. The Rapid Sleeve is our 10 inch metal pipe sleeve with an elongated drip cap and a lower flare that seals any plumber vent: no more rubber collars and no more spray paint. See the whole lineup on our products page.

Who we make it for

For every roof. For every professional.

For Home Owners & Associations

The pipes and vents on a roof are small, but they give the whole job away when they are the wrong color. Our stone coated vents and flashings are long lasting and maintenance free, rust, rot, algae and fire resistant, and they never need another coat of paint. Every product is backed by a limited 25 year product warranty. We make them, your roofer installs them, and your local contractor can give you pricing. Associations that want a whole community finished to one standard will find more on our page for home owners and associations.

For Roofing Contractors

If you roof for a living, you know the last step of the job: mask the pipes, shake the can, paint the jacks and hope it holds. Stone coated flashings skip that step. They go on with no special tools, they never need painting, and they are priced to go on every roof, not only the big ones. Put them on all of your roofs and they become your personal signature of quality, which is a marketing edge the painted pipe down the street does not have. Colors, the full flashing list and how to order are on the contractors page.

Why Stone Coat?

Why Stone Coat Your Flashings

It comes down to a few plain facts. Stone coated products do not need cleaning or painting, and they will not suffer UV deterioration or rust. A proprietary formulation lets them stand up to hail, freeze, thaw and extreme heat. The seam on the cone, where spray paint cannot seal, comes sealed water tight. Add the look, the easy install and a reasonable price, and you have the nine reasons laid out on Why Stone Coat?, along with more before and after photos.
