Manchester Premium Roofing provides professional chimney flashing in Manchester, NH for residential and commercial properties across southern New Hampshire. The chimney produces more leaks in Manchester than any other part of a roof, because it is the one place a moving timber roof is tied to rigid old masonry. Get that junction wrong and the quality of everything else stops mattering.
The detail has two halves that must stay separate. Step flashing is woven into the shingle courses and belongs to the roof. Counterflashing belongs to the wall, anchored in masonry and lapping over the step flashing while never being fixed through it, which lets the roof move seasonally without tearing metal. Sealing the two together into one rigid mass is the commonest mistake we find, and it fails within a few years.
This is where Manchester differs from a newer city, and most contractors get it wrong. Brick laid before roughly 1900 was bedded in soft lime mortar, and lime mortar is softer than the brick by design, so movement and salts are taken up by the joint rather than the masonry face. Running a grinder through it to cut a reglet, then refilling with a modern portland-based mix, makes the joint harder than the brick around it.
The brick face then spalls at the next freeze and the flashing loses its anchor. So we test the mortar before deciding the detail. Where it is soft and original, we rake the joint by hand, set the counterflashing with lead wedges and repoint in a lime-compatible mix rather than a hard one. Where the wall is too far gone to cut at all, we fit a surface-mounted counterflashing anchored above the mortar line into sound brick.
A saddle goes behind any chimney wider than thirty inches, because a flat pocket on the upslope side collects everything the roof delivers. That is a code requirement and it is also simply true, and we price it as its own line so it cannot quietly vanish from a bid. We price it as its own line so it cannot quietly disappear from a competing bid. It looks humbler and it is correct.
And when the problem is the crown or the brick itself rather than the flashing, we say so and tell you to call a mason. Roofers who insist every chimney leak is a flashing leak sell a lot of flashing. Spalled brick and a failed crown are mason's work, and taking them in the wrong order means paying for the flashing twice.
Our licensed and insured team brings the right materials and equipment to every job — surface-mounted counterflashing anchored above the mortar line, joints raked and repointed in soft Type O lime mortar, lead wedges setting flashing into a raked brick joint, shingles tested to ASTM D3462 and classified to D7158, net free ventilating area computed to IRC R806.2, a saddle framed to the 30-inch chimney threshold — and backs the work with a written workmanship warranty. We serve Manchester and nearby communities including Bedford, Goffstown, Hooksett, Merrimack.

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 surface-mounted counterflashing anchored above the mortar line, joints raked and repointed in soft Type O lime mortar, lead wedges setting flashing into a raked brick joint, shingles tested to ASTM D3462 and classified to D7158, 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 Manchester 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 southern New Hampshire means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

- ✓Our inspections are paid and the written report belongs to you, so our finding is allowed to be that your roof needs nothing this year.
- ✓Where a roof meets old brick we set flashing into a raked joint and repoint in soft lime mortar, and we will not run a grinder through a wall that cannot take one.
