Roofing Companies in Phillipsburg, NJ
Phillipsburg is Warren County’s most populous municipality, with about 15,200 residents on just over three square miles along the Delaware River across from Easton, Pennsylvania. It became a transportation hub after the Morris Canal reached the river here in 1831, and at one time five major railroads converged in town. Ingersoll Rand opened its Ingersoll-Sergeant factory here in 1903, employing as many as 5,000 people at its peak before closing in 2000. Three Delaware River bridges, including the Northampton Street “Free Bridge,” connect Phillipsburg with Pennsylvania, and Pohatcong Mountain extends northeast from town. Phillipsburg borders Lopatcong and Pohatcong townships.
Monarch Roofing & Construction serves Phillipsburg from our office at 168 Humboldt St in East Rutherford. We repair and replace residential roofs, repair chimneys and flashing, and replace gutters and siding.
Roofing in a Historic Railroad and Factory Town
With about 6,700 housing units in three square miles, Phillipsburg is densely built for Warren County. Much of the town grew during its canal, railroad, and manufacturing years, and its homes reflect that history.
Older homes and many layers
Homes that have been reroofed several times over a century often carry two or more layers of shingles on top of board sheathing. Extra layers trap heat, hide soft spots, and add weight to old rafters. On replacements we strip every layer, replace damaged boards, and add a modern underlayment and leak barrier.
Multi-family and rental homes
For owners of two-family homes and rentals, a roof leak means two problems: damage to the building and disruption for tenants. We schedule around occupants, protect interiors where we can, and give owners clear written findings and options.
Steep and narrow streets
Where driveways are steep or streets are narrow, they affect where a dumpster can go and how materials are delivered, so we plan logistics during the estimate.
Low-slope porch and rear roofs
Porches and rear additions on older homes frequently have shallow pitches. Shingles need a minimum slope to shed water, so we check the pitch and explain what material is suitable for each section rather than extending shingles where they will not perform.
River valley weather
Winters bring snow and freeze-thaw cycles, and summer storms can push wind-driven rain into weak flashing. Good attic ventilation, leak barrier at the eaves, and sound flashing at walls and chimneys handle both.
Roof Repair in Phillipsburg
Common repairs include rebuilding flashing where roofs meet walls and chimneys, replacing broken or missing shingles, replacing cracked vent boots, and repairing valleys. We locate where water enters before recommending a fix, because a stain on one side of a room can start several feet away. See our roofing services.
Roof Replacement in Phillipsburg
A replacement includes removal of all layers, repair of sheathing, synthetic underlayment, leak barrier at eaves, valleys, and walls, new drip edge, new step and counter-flashing, new shingles, and ventilation suited to the attic. We keep sidewalks clear and clean up nails at the end of each day.
Chimney Repair
Brick chimneys on older homes face decades of frost. Spalled bricks near the top, a cracked crown, and flashing sealed over with tar are the usual problems. We repoint, rebuild crowns, rebuild the stack above the roof where needed, and install new step and counter-flashing. See chimney repair and flashing.
Gutters and Siding
Sloped lots move a lot of water. Gutters must be sized and pitched correctly, and downspouts should carry water away from foundations and neighboring property. We replace gutters and downspouts, repair fascia, and repair or install siding. Visit our gutter and siding page.
Getting a Good Estimate
Ask each contractor to list tear-off, sheathing repair pricing, underlayment, leak barrier, flashing, ventilation, and cleanup in writing. Confirm whether any permit or approval applies from the Town of Phillipsburg, and check the contractor’s New Jersey home improvement registration with the Division of Consumer Affairs.
Phillipsburg Roofing FAQs
Do you work on two-family homes and rentals?
Yes. We coordinate with owners and tenants and protect occupied units during the work.
My porch roof leaks but the main roof is fine. Why?
Porch roofs often have a lower pitch than shingles are designed for, and the joint where the porch meets the house wall is a common leak point.

Yes. We plan dumpster placement and deliveries around the street and driveway.

How do I choose a reliable roofing contractor?
Verify New Jersey Home Improvement Contractor registration with the Division of Consumer Affairs. Ask for a written scope listing materials, the number of layers to remove, and how hidden damage is priced; ask whether any permit or approval applies; and request proof of insurance.
Should I repair or replace my roof?
A single failed flashing or a few missing shingles on a sound roof is usually a repair. Multiple layers, widespread wear, and soft board sheathing usually point to replacement.
How much does roof replacement cost in Phillipsburg?
Cost depends on roof size and pitch, the number of layers, board sheathing repairs, chimney and flashing work, ventilation, the shingle line, staging on steep or narrow streets, and any permit or approval fees that apply. A free written estimate after an inspection gives the real figure.
What are the signs of roof damage?
Look for missing or curled shingles, sagging between rafters, granules in gutters, loose chimney mortar, and ceiling stains on top floors.

What You Can Count On
Honest Roof Assessments. Clear Recommendations. Repairs When Possible. Replacement When Necessary. Phillipsburg’s long-standing homes and two-family houses deserve straightforward advice. We inspect carefully, explain what we find, and recommend only the work that is needed.
Handling Hidden Damage During a Roof Replacement
On older homes, some conditions can only be seen once the old roofing is removed. Knowing how these are handled ahead of time avoids surprises:
- Unit pricing in the estimate. A clear estimate lists how damaged boards or sheathing will be priced, such as per sheet or per board.
- Notification before extra work. If significant hidden damage is found, you should be told what was found and shown photos before additional work proceeds.
- Written change orders. Any change to the scope should be documented in writing.
- Weather protection. Exposed areas should be protected while decisions are made.
- Final accounting. The final invoice should show any added items clearly.
Two-Family Houses: Separate Attics and Shared Roofs
Many Phillipsburg homes are two-family houses. Their roofs bring a few specific considerations:
- Each unit may have its own plumbing vents and exhaust fans, adding penetrations that each need flashing.
- Attic spaces may be divided, and each section needs its own ventilation path.
- Leaks can show up in one unit even when the source is above the other.
- Scheduling and notice for tenants keep the project running smoothly.
Phillipsburg’s Weather
Along the Delaware River, winters bring snow and freeze-thaw cycles that cause ice dams and wear on chimney masonry. Summer storms can push wind-driven rain into weak flashing.

- Valleys, walls, and porch roof transitions

Leak Diagnosis
Roof leak repair in Phillipsburg traces water from the attic back to its source, which may be above a different unit than the stain. After a storm, photograph damage and note the date. Your insurance company decides coverage; we can inspect and describe the roof’s condition.
Flashing and the Layers Beneath
Chimney flashing with counter-flashing set into mortar, new pipe boots, step and kick-out flashing, drip edge, ice and water shield at the eaves and valleys, synthetic underlayment, and replacement of damaged boards make up a complete roof system.
The Replacement Process
- Free inspection and written estimate.
- Permit, if required, and scheduling, with tenant notice where needed.
- Protection for property, neighbors, and sidewalks.
- Tear-off of all layers to the deck.
- Board sheathing repairs, with notification for any significant hidden damage.
- Drip edge, ice and water shield, and underlayment.
- New flashing.
- Asphalt shingles, ridge vent, and caps.
- Cleanup and nail sweep.
- Final walk-through.

A Closer Look at Roofs in Phillipsburg
Phillipsburg is Warren County’s most populous municipality, packed onto just over three square miles along the Delaware River across from Easton, with older homes, two-family houses, and steep, narrow streets that reflect its history as a railroad and factory town. Beyond the topics above, this section covers winter ice and warm attics, condensation, roof-to-wall joints, valleys, ridge caps, chimney crowns and caps, mixing ventilation types, exhaust ducts, old roof mounts, gutters on sloped lots, selling or buying a rental, and handling a leak.
Winter ice and warm attics
On cold days after snow, warm air leaking into the attic melts snow on the upper roof, and the water refreezes at the colder eaves. The resulting ice traps water that can back up under shingles. In older houses, open stairways, unsealed attic hatches, and gaps around chimneys and plumbing stacks are common heat leaks. Air sealing and balanced ventilation reduce the ice; ice and water shield along the eaves protects against leaks when it forms.
Condensation or a leak?
Frost on nail tips, rusty nails, and broad staining on dry days usually point to condensation from warm, moist indoor air rather than a roof leak. Two-family homes with more bathrooms and kitchens produce more moisture, and if fans vent into the attic, condensation becomes likely. Air sealing and venting fans outdoors address it.
Roof-to-wall joints
Dormers, second stories, and rear additions create joints where a roof meets a wall. Step flashing tucked behind the siding and kick-out flashing at the bottom keep water out. When those pieces are missing or covered with caulk, water runs behind siding and rots the wall. We install siding as well as roofing, so these joints can be rebuilt properly.
Valleys
Valleys carry water from two slopes and heavy meltwater in late winter. Closed-cut and open metal valleys both work with architectural shingles, provided ice and water shield runs their full length underneath.
Ridge caps
Wind moving through the river valley works at the ridge. Purpose-built hip and ridge shingles bend over the peak without cracking and should be fastened with nails long enough to reach solid wood.
Chimney crowns and caps
Older homes often have brick chimneys that have weathered many winters. The crown, the sloped concrete top, sheds water off the brick; cracks let water soak into the masonry. The cap covers the flue. A cracked crown can make a chimney leak even when the flashing is sound. Our chimney services include repair, rebuilding, and flashing.
Mixing ventilation types
Combining a ridge vent with box vents, gable vents, or a powered fan can short-circuit airflow. A balanced system usually uses one exhaust type with enough soffit intake.
Exhaust ducts
Bathroom fans and kitchen hoods should exhaust outdoors through flashed caps. During a replacement, new vent caps are installed and every duct can be checked.
Old roof mounts
Many roofs carry old antenna or satellite dish brackets bolted through the shingles. Their sealant cracks over time. Remove unused mounts and patch the holes, or eliminate them during replacement.
Gutters on sloped lots
On steep streets, downspout outlets need to carry water away from the foundation without dumping it onto sidewalks or a neighbor’s property. Gutters hung on soft fascia pull loose under ice. Sound fascia, secure hangers, and well-placed outlets help. We install gutters along with roofing.
Selling or buying a rental property
Buyers’ inspectors will note a roof’s age and condition. Sellers can get ahead with a roof inspection, targeted repairs, and records. Buyers should ask for records, check each unit’s top-floor ceilings and the attic, and have the roof inspected closely. Our inspections are free and include photos.
When a leak starts
Put a bucket under the drip, lay towels down, and move belongings. If a ceiling is bulging with water, a small hole at the lowest point lets it drain into the bucket. Take dated photos, stay off the roof, and call or text (551) 241-0470 once it is safe.
After a storm
Be cautious of anyone who pushes for an immediate contract, a large payment up front, or promises about insurance. Ask for a written estimate and a New Jersey Home Improvement Contractor registration number. Your insurer decides coverage.
Keeping records
Keep the installation date, shingle product and color, invoices, and dated photos together, especially for rental properties.
Phillipsburg Roofing FAQs, Continued
Why does ice form along my roof edge?
Warm air escaping into the attic melts snow that refreezes at the cold eaves.
Can my attic be damp without a roof leak?
Yes. Condensation from indoor moisture is a common cause, especially when fans vent into the attic.
What is kick-out flashing?
A diverter at the bottom of a roof-to-wall joint that sends water into the gutter instead of down the wall.
Can a cracked chimney crown cause leaks?
Yes. Water can soak into the masonry through the crown and show up inside.
