Marshall TX Roof Pros provides professional chimney flashing in Marshall, TX for residential and commercial properties across Harrison County and the Big Cypress basin. The rest of this site keeps circling back to this one page. More of our leak work in Marshall starts at a chimney than anywhere else on the roof, and the reason is not the metal. It is what the metal has been asked to hold on to.
Understand the wall. Mortar is the sacrificial part of a wall, softer and more vapor-permeable than the brick, so weathering wears the joint rather than the unit. The ASTM C270 types run from Type M near two thousand five hundred psi down through Type N to Type O at three hundred and fifty and Type K at seventy-five. Marshall's nineteenth-century brickwork wants the bottom of that range, and Portland cement was not manufactured in this country until 1872.
Two habits break that rule. The first is repointing a chimney with a bagged high-strength mix because that is what was on the truck. The joint becomes harder than the brick, so the next wet cycle takes the brick face instead and the wall spalls in patches. The second is cutting a reglet across the brick face with a cut-off wheel, which on thin joints chips the unit edges and overcuts the head joints.
Our detail is old-fashioned and it works. Joints are cut back by hand where they are thin, the reglet is taken in the bed joint rather than the brick, counterflashing is hemmed, folded into that joint and pinned with lead wedges, and the joint is then pointed with a mortar chosen to be weaker than the brick around it and kept damp while it cures. Step flashing underneath goes in course by course, never as one bent length.
The cricket is the other half. Any chimney wider than roughly thirty inches on the slope wants a framed cricket at its back, since without one the upslope face is simply a dam. In this county what collects behind that dam is loblolly needles and bark, which hold a wet compress against the brick for weeks after a rain and do more damage than the water alone ever would.
Crowns finish the job. A thin mortar wash troweled over the top cracks within a few years. We cast a proper crown with a drip overhang past the face and an expansion joint at the flue, so water leaves the chimney instead of running down it.
Our licensed and insured team brings the right materials and equipment to every job — pointing mortar batched to ASTM C270 Type O at 350 psi, counterflashing let into a raked bed joint and pinned with lead wedges, hand-chiseled joint preparation in place of a cut-off wheel, a chimney cricket framed to shed water clear of the flue, cast concrete chimney crown with a drip overhang past the brick face, vapor-permeable pointing that lets a brick wall dry outward — and backs the work with a written workmanship warranty. We serve Marshall and nearby communities including Longview, Hallsville, Waskom, Scottsville.

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 pointing mortar batched to ASTM C270 Type O at 350 psi, counterflashing let into a raked bed joint and pinned with lead wedges, hand-chiseled joint preparation in place of a cut-off wheel, a chimney cricket framed to shed water clear of the flue, 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 Marshall 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 Harrison County and the Big Cypress basin means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Marshall Chooses Marshall TX Roof Pros
- ✓We survey every roof-to-brick termination with a probe before quoting, and you get those photographs whether or not the job is ours, because the joint depth is the number that decides the scope.
- ✓Pointing mortar is specified by ASTM C270 type and chosen to be weaker than the brick around it, so the joint stays the part that wears rather than the face of the wall.
- ✓Joint preparation is done with hand chisels wherever the joints are thin. A cut-off wheel is faster and it breaks brick edges and overcuts the vertical joints, which you then live with forever.
- ✓We turn down elastomeric coating work on masonry, every time it is asked for, and explain what trapping moisture behind a brick face actually does to the wall over a wet winter.

If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
