Hillsborough Roofing provides roof repair, roof replacement, roof leak repair, storm damage work, and siding installation for homeowners in Hillsborough, NJ and across Somerset County. Asphalt shingle roofs are the bulk of the work, alongside low-slope sections over porches and additions, gutters, soffit and fascia, skylights, and siding in vinyl and fiber cement. When a roof is coming off, Hillsborough Roofing handles the siding at the same time, so the wall and roof details get flashed together rather than a year apart.
A roof gets looked at before it gets priced: walked where it is safe to walk, checked from the attic side for staining and daylight, with the flashings, valleys, pipe boots, and ventilation photographed. Sometimes the answer is a repair that buys another handful of seasons, and sometimes the shingle line is spent. Both are written up the same way, and neither is treated as the real job while the other is a consolation.
The service area runs from Hillsborough out through Bridgewater, Somerville, Montgomery, Branchburg, Manville, Belle Mead, Neshanic Station, and Raritan. Roofs here take a specific beating. Nor’easters drive rain sideways under shingle courses and up under flashing. Freeze-thaw works at every crack and nail hole from December through March, and ice dams back water under the field at cold eaves. Tree cover along the Sourland ridge drops limbs, holds moisture on north slopes, and packs valleys. Then summer thunderstorms bring wind and hail that crease a roof that looked fine in June.
Roof work, done in the order that protects the house
Repair and replacement carry the same weight here. A sound roof with a failed flashing detail gets the flashing fixed. A roof at the end of its shingle line gets torn off and rebuilt. Leaks, storm damage, skylights, gutters, and low-slope work sit alongside those two.

Tarping and temporary dry-in when a storm opens the roof and water is coming in now.
Storm & Hail Damage Repair
Reading a storm-hit roof honestly: wind creases, hail bruising, test squares, and claim documentation.
Solar Panel Removal & Reinstall
Roof replacement under an existing solar array, sequenced with your solar installer.

Siding, flashed to the roof instead of around it
The wall and the roof meet at step flashing, kickouts, and rake edges, which is where most water gets in. Working both means those junctions get built as one detail. Vinyl and fiber cement are both installed here.

From the first ladder set to the last magnet pass
- 01
We get on the roof and into the attic
Each side of the deck tells half the story. Up top we read shingle condition, flashings, valleys, boots, and vents. Underneath we look for staining, rusted nail shanks, daylight at the sheathing seams, and whether the ventilation moves air.
- 02
Everything found gets photographed and labeled
You get the pictures, not a verbal summary. Each shot is tied to a spot on the roof, so you see the cracked boot, the rusted step flashing, or the lifted course yourself. If a claim is involved, that set is what an adjuster needs.
- 03
A written number, with the options side by side
The quote lists scope, materials by name, and what the price includes. Where repair and replacement are both defensible, both get priced so you can compare them on paper. Nothing gets quoted from the driveway before the roof is looked at.
- 04
Tear-off or targeted repair, done clean
On a replacement the old roof comes off to the deck, bad sheathing gets swapped, and the new system goes down in order. On a repair we open only what needs opening and tie the new material into the existing courses so it sits flush.
- 05
We walk it with you before the trailer leaves
Ground walk of the perimeter, magnet passes across the lawn, beds, and driveway, gutters cleared of tear-off debris. Then we go over the finished work with you, hand over the warranty paperwork, and answer anything left before we drive off.
The parts of a roof that decide how long it lasts
Most of a roof is invisible once the shingles are on, and that hidden layer decides whether it makes its service life. Ice and water shield is a self-adhering membrane that seals around fasteners, run at the eaves, valleys, and penetrations so water backed up by an ice dam has nowhere to go. Over the rest of the deck goes synthetic underlayment, which stays flat and resists tearing in wind instead of wrinkling like wet felt.
At the perimeter, drip edge carries water off the deck into the gutter rather than curling back onto the fascia. Where a roof plane meets a wall or chimney, step flashing is woven into each shingle course so every course has its own metal, which is why one caulked strip is a leak waiting to happen. At the peak, a ridge vent with intake at the soffits exhausts heat and moisture, keeping decking dry and shingles from cooking from below.
For the visible layer we run architectural shingles, laminated to be heavier and more wind resistant than 3-tab. The lines we install most are GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark, all with comparable wind ratings. The choice usually comes down to color range and how the granule blend sits against your siding.
Working out of Hillsborough, across the towns next door
Hillsborough is home base, and the neighboring Somerset County towns are a short drive rather than a special trip. That matters when a leak starts on a Sunday or a storm comes through overnight and a tarp has to go on before the next band.

How much does roof repair or replacement cost in Hillsborough?
It comes down to a handful of measurables. Square footage and pitch set the labor, since a steep roof needs staging and moves slower. How many layers have to come off changes disposal. Decking condition is the variable nobody can see until the old roof is off. Then the shingle line you pick, how much flashing and ventilation work the roof needs, and access for the dumpster and the loading conveyor. We measure all of it and put the number in writing.
How do you decide whether to repair a roof or replace it?
Age against the shingle line, how much of the roof is actually failing, and whether the deck underneath is still sound. A roof with life left and one bad valley or a rotted pipe boot is a repair, full stop. A roof shedding granules across the whole field, with brittle shingles that crack when you lift them, is spending good money on patches. When both are defensible we price both and show you the photos behind each option.
How long does a roof replacement take from start to finish?
Most single family homes here are a one or two day job once we start. Tear-off and dry-in happen the same day, so the deck is never left open overnight. Larger roofs, steep pitches, multiple dormers, or bad decking found during tear-off add time. Weather is the real variable, and we would rather push a start date than open a roof ahead of a storm. You get a date range up front and a call if anything moves.
Do you work with insurance on storm damage claims?
Yes, in the way that helps most: thorough documentation. We photograph wind creasing, hail bruising, lifted courses, and any tree strike damage, and we can meet your adjuster on site to walk the roof together. What we will not do is tell you a claim will be approved. That decision belongs to your carrier and depends on your policy and their inspection. Our job is to make sure the damage is recorded accurately before anything gets covered up.
Can you replace a roof that has solar panels on it?
Yes. The array gets detached and set aside, the roof is torn off and rebuilt underneath, then the panels and racking go back with the standoff penetrations flashed into the new roof. It takes coordination with your solar installer or monitoring company, and there is some downtime on production while the panels are off. The sequence and what to expect on warranties from both sides is covered on our solar panel removal and reinstall page.
