Roofing Services in New Hampshire That Hold Through Winter

New Generation General Construction installs, replaces and repairs residential roofs in New Hampshire. The work covers full tear offs, new construction roofing, storm damage repair and leak diagnosis. Every roof begins with an inspection of the deck, the flashing points and the attic ventilation. Nothing is covered over without being looked at first. The estimate that follows is written and itemized. The homeowner sees the cost of materials, labor and disposal before deciding. Roofing is licensed and insured work, and both are current.

Roofs in New Hampshire fail in ways that roofs in milder states do not. Snow sits on the surface for weeks. Meltwater refreezes at the eaves and backs up under the shingles. Wind driven rain finds any gap in the flashing around a chimney or a valley. A roof installed to the minimum specification will survive a mild year. Then it leaks in a hard one. The details that prevent that failure cost very little at installation and a great deal to correct later.

Homeowners call for three reasons. The roof has reached the end of its life and needs replacing. A storm has torn shingles loose or opened a seam. Or water is already coming through a ceiling and the source is unknown. All three start the same way, with someone on the roof and in the attic before a price is quoted. Guessing at a roof from the driveway produces a number that changes halfway through the job. That is not how this company works.

01 Roof Installation and Replacement in New Hampshire

A replacement begins with a full tear off down to the deck. Layering new shingles over old hides rot and adds weight the structure was never designed to carry. With the deck exposed, soft spots and damaged sheathing are visible and can be replaced before anything else goes down. Ice and water shield goes on at the eaves and in the valleys. Synthetic underlayment covers the rest of the field. Drip edge, starter course and ridge vent follow in the order the manufacturer specifies.

Material choice depends on the pitch, the exposure and the budget. Architectural asphalt shingles handle most New Hampshire homes and carry a longer rated life than three tab. Standing seam metal sheds snow faster and lasts decades, at a higher installed cost. Low slope sections over a porch or an addition need a membrane rather than shingles. Shingles depend on gravity to shed water. Putting the wrong material on the wrong pitch is one of the most common reasons a roof leaks early.

Ventilation is the part homeowners never see and the part that decides how long the roof lasts. Intake at the soffit and exhaust at the ridge keep the attic close to the outside temperature. A warm attic melts snow from below, which is where ice dams begin. On every installation the intake is checked before the ridge vent goes on. A ridge vent with blocked soffits moves no air at all. That single check has saved more roofs than any premium shingle.

02 Roof Repair and Leak Diagnosis in New Hampshire

A leak rarely enters where it appears. Water travels along the underside of the deck, then down a rafter. It drops onto the ceiling several feet from the actual opening. Chasing the stain instead of the source is how a roof gets patched three times and still leaks. The process starts in the attic on a dry day. Look for daylight, staining on the sheathing and rusted nail points. From there the exterior location can be identified with some confidence. That step takes an hour and saves a season.

Most repairs fall into a short list. Flashing that has pulled away from a chimney or a sidewall. A cracked boot around a plumbing vent. Shingles lifted by wind at a rake edge. Nail pops that have worked through the surface over several freeze cycles. Each of these is a small material cost and a short visit. Left alone through a New Hampshire winter, the same opening lets meltwater into the sheathing repeatedly. The repair then becomes a section of deck instead of a tube of sealant.

There is a point where repair stops making sense. The shingles are brittle, the granules are in the driveway and three areas have already been patched. At that point, more repairs only delay the replacement. That assessment is given honestly, in writing, with the reasoning attached. Some homeowners get another two winters out of a roof and that is the right call. Others are spending repair money on a roof that will not survive the next storm. Both answers come with a number, not a sales pitch.

03 Why Roofing Quality Matters in New Hampshire

New Hampshire sits in a climate that tests a roof from both directions. Winter brings accumulated snow load, ice dams at the eaves and repeated freeze thaw movement in every fastener. Summer brings heat that softens asphalt and thunderstorms that drive rain sideways under lifted shingles. A roof here works harder in one year than a roof in a mild climate works in three. Quality is not a premium here. It is the difference between a roof that reaches its rated life and one that does not.

Building code sets a floor, not a standard. Ice barrier requirements, fastener counts, deck thickness and edge details exist because those points fail first. Meeting them is the minimum for a legal roof. Exceeding them costs very little on the details that matter most. An extra course of ice and water shield at the eaves. A proper kick out flashing where the roof meets a wall. Those choices separate a roof that lasts from a roof that merely passes inspection.

The cost of getting it wrong is never limited to the roof. Water that reaches the sheathing moves into the insulation, then the framing, then the ceiling below. Insulation that has been wet once no longer performs, and the heating bill reflects that every winter after. Mold follows moisture in a closed attic. A roof done correctly is not an expense that competes with the rest of the house. It is the thing that protects everything under it. That is the frame the estimate should be judged against.
