Roof Repair in Hillsborough, NJ
Hillsborough Roofing repairs failing spots on asphalt shingle roofs across Hillsborough and Somerset County. Most of what we fix is small and specific: a lifted course over the garage, a row of nail pops on a south slope, a pipe boot split by the sun. We find the failing point, show you what it looks like, and tell you plainly whether a repair holds.
Finding the spot that is actually failing
A roof rarely fails all over at once. It fails at a joint, a penetration, or a course that took more sun and wind than the rest. Our first job is to narrow the roof down to that spot rather than sell you the whole plane. We walk the slopes, check the attic side where we can reach it, and look at what makes a shingle stop sealing: heat off a low-slope garage roof, moss on a shaded north face, a valley carrying two planes worth of water.
Once we find it we tell you which of two things you have. Either the field around the failure is still sound, and a repair is honest work that buys real years, or the failure is one symptom of a slope shedding granules everywhere.
The four failure points we fix most often
These four account for the large majority of repair calls we take in Somerset County. Each one has its own fix and its own tell.
Lifted and creased shingle tabs
Wind gets under a tab that never sealed, or a nor’easter creases a course hard enough to break the mat while the shingle stays on the roof. Creased tabs look fine from the driveway and leak in the next driving rain. We replace the affected shingles and the course above them so the new nails land under cover, and hand seal the tabs when it is too cool for the strip to bond.
Nail pops and backed-out fasteners
Decking moves with the seasons and pushes nail heads up through the shingle above. You get a tented bump, then a pinhole, then a ceiling stain two winters later. We pull the popped fastener, refasten into sound decking away from the old hole, and seal the penetration rather than smearing over the bump.
Cracked and dried pipe boots
The rubber collar around a plumbing vent is usually the first thing on a roof to fail outright. Sun cooks it, it splits at the top, and water runs down the outside of the pipe into the ceiling below. A cheap part, a common cause of an expensive stain. We weave a new boot into the surrounding courses rather than caulking one on top of them.
Rusted or short step flashing
Where a plane meets a wall, dormer cheek, or chimney, each shingle course needs its own piece of step flashing lapped under the one above. On older homes here we regularly find one long strip of metal instead, or step flashing rusted through at the bottom. The repair means opening the siding back, setting new step flashing course by course, and returning the counter flashing over it.
Patch, section, or slope
We think about repair in three sizes. A patch is a handful of shingles around one point of damage. A section is a defined area, one dormer face, one valley run, the field below a chimney, taken back to sound material. A slope is the whole plane.
Weathering matters here. Asphalt changes shade as it ages, so a repair on an older roof will show, and we say so beforehand rather than after. When repair no longer makes sense at any of those three sizes, we say that too and walk you through roof replacement with the same directness.
What a repair visit includes
- A look at the failing area from the roof, plus the attic side when it is accessible
- Photos of the actual defect so you are not taking our word for it
- A clear call on whether the surrounding field is sound enough to hold a repair
- Flashing, boots, and fasteners replaced rather than sealed over
- Old material off the property and a magnet run over the drive
