Manchester Premium Roofing provides professional commercial roofing in Manchester, NH for residential and commercial properties across southern New Hampshire. Commercial work in Manchester splits into two populations that need different thinking. There is nineteenth-century brick, much of it along the river and converted to offices and apartments, and there is late-twentieth-century single-story building along the highway corridors.
On the brick buildings the field membrane is rarely the problem. These roofs are surrounded on every side by masonry, so the money and the risk are in base flashings, coping, parapet terminations and the places where roof water is asked to leave through a wall. We survey terminations first and the field second, the reverse of the usual order. Finding the failure where it is saves an owner buying a field replacement he did not need.
The alteration code applies to that work. New Hampshire adopted the 2021 International Existing Building Code alongside the residential and building codes, and it treats work on an existing structure on its own terms rather than pretending it is new construction. Naming the applicable code on a commercial scope is not pedantry; it decides what is required of the job. Owners are entitled to know which code their building is being held to.
On the newer buildings the pattern is drains, curbs and edge metal. Roof-top units get serviced by people who are not roofers, and the accumulated damage around a curb from years of that traffic is where a twenty-year membrane fails at twelve. We photograph and number every penetration so a building owner has a record rather than a general impression. A record beats an impression when a budget is being defended.
We survey with core samples where the assembly is unknown. Cutting and patching a small core tells you the deck type, how many systems are already up there and whether the insulation is wet, and it converts a guess about a roof budget into a number. Owners planning capital work get considerably more use out of that than out of a free walk-around.
And we will tell an owner to defer. A membrane with five years in it does not need replacing this year because it looks tired, and a phased plan that repairs terminations now and budgets the field for later is often the correct advice. We would rather hold a maintenance relationship for a decade than sell one oversized roof. Deferring well is a service, and it is the advice we would want in your position.
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 commercial roofing
The difference between commercial roofing that lasts and commercial roofing 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.

Why Manchester Chooses Manchester Premium Roofing
- ✓We tell you plainly that New Hampshire issues no roofing license, then show you the three things about a contractor you actually can verify here.
- ✓The warranty is written before the sale, not handed over at the end, because the statute reads that document to decide whether your complaint counts as a defect.
- ✓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.
The standards behind commercial roofing
Quality here is not a matter of opinion — it is written down. The commercial roofing work we do in Manchester follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
Every commercial roofing project in Manchester gets the same attention, whether it is a single room or a full commercial job. We show up on schedule, keep the site clean, and stand behind the work — the estimate is free and there is no pressure.
