Allen Premium Roofing provides professional chimney flashing in Allen, TX for residential and commercial properties across the US 75 corridor. Chimney flashing is the most reliably wrong detail on an Allen roof, and it is wrong the same way on nearly every house: surface-mounted metal held in place with sealant. It is quick, it looks finished, and it is a four-year repair sold as a permanent one.
Most chimneys in this stock are framed chases finished in brick veneer or siding and capped with a sheet metal cover, rather than solid masonry stacks. That matters twice over. A veneer chase does give you a mortar joint to cut into, and the hollow structure behind it will hold water for years without ever telling anybody about it. By the time a ceiling stains, the framing inside has been wet a while.
Done properly there are two layers of metal. Base flashing that steps up the sides with the shingle courses and turns up against the chase, and counterflashing cut into the mortar joint, folded into the reglet and locked down over the base. The two are able to move independently, which is the entire point, because a chase and a roof deck do not move together. Anything rigidly bonding the two tears itself apart in two Texas summers.
What we find instead is one layer screwed to the brick with a bead of sealant across its top edge, or an L-shaped piece of aluminum tucked under a course and caulked. Both work for roughly four years. Then the sealant cracks, water runs behind the metal, and it appears inside well away from the chimney because it travels along the top of the ceiling.
The other half of the job is upstream of the chimney. A chase wider than thirty inches measured across the slope needs a cricket behind it, and the residential code Texas cities adopt requires one. Plenty of chases here are wider than that and have nothing but a flat field of shingles collecting leaves and holding water against the back wall. We build crickets in metal. A shingled cricket on a shallow pitch fails the same way.
While we are up there we look at the cover on top. The original is usually flat galvanized steel with sealed seams, which rusts through and then drips down inside the chase for years unnoticed. Its replacement is a cross-sloped stainless or copper pan with folded corners, a drip edge and no sealed seams, and it is one of the few roof parts you install once.
Our licensed and insured team brings the right materials and equipment to every job — architectural laminate shingles fastened six per shingle inside the nailing zone, UL 2218 Class 4 impact-rated laminates, synthetic underlayment fastened with plastic cap nails, starter course carrying a factory-applied adhesive strip at eave and rake, gutter apron and drip edge in 26-gauge painted steel, reglet-cut counterflashing folded into the mortar joint — and backs the work with a written workmanship warranty. We serve Allen and nearby communities including Plano, Frisco, McKinney, Richardson.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney flashing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with architectural laminate shingles fastened six per shingle inside the nailing zone, UL 2218 Class 4 impact-rated laminates, synthetic underlayment fastened with plastic cap nails, starter course carrying a factory-applied adhesive strip at eave and rake, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Allen job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the US 75 corridor means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Allen Chooses Allen Premium Roofing
- ✓We date the roof before we quote it, using the shingle line, the permit record for the address and the tear-off count read from the attic, because most Allen roofs are second roofs and the age of the house tells you nothing useful.
- ✓Every estimate is itemized by detail. Boots, valley metal, edge metal, counterflashing, ridge slot and decking are separate lines, so a repair can be compared honestly against a replacement instead of guessed at.
- ✓When the shingle field is sound and only the reused components have failed, we put the recommendation to wait in writing, with a date to look again and the three things worth watching until then.
- ✓Sealant is used only where a manufacturer's instructions call for it. Chimneys get counterflashing cut into the mortar joint, plumbing vents get new boots, and nothing gets a bead of mastic in place of metal.
