Roof Repair Services in Harrison Township, NJ

Named in 1845 for President William Henry Harrison, Harrison Township grew around the old village of Mullica Hill and now reaches across about 19 square miles to Ewan, Ewans Mills, Jefferson, Sherwin, Heritage, and part of Richwood, roughly 4,100 homes. (It is the Gloucester County township, not the Hudson County town called Harrison.) Whether your house is a Mullica Hill original with dormers and a porch or a newer home where the garage roof butts into a two-story wall, the weak spot tends to be the same: the seam between roof and wall. Monarch Roofing & Construction treats that seam as a priority in every roof repair in Harrison Township NJ, and handles storm damage, shingles, chimney flashing, pipe collars, valleys, skylights, porch roofs, and ice damage as well. Call or text (551) 241-0470; our regional location in Haddonfield will set up a no-cost inspection.

The core of this page explains roof-to-wall joints in detail: the pieces involved, why they fail on older and newer homes, and how they are rebuilt. After that come storm preparedness in light of the 2021 tornado, other common repairs, leak tracing, the inspection, and the repair-or-replace decision, then FAQs.

Harrison in Brief

Incorporated in 1844 as Spicer Township, Harrison borders East Greenwich, Elk, Glassboro, Mantua, South Harrison, and Woolwich. U.S. Route 322 and County Route 536 run through the center of Mullica Hill, and Routes 45, 55, and 77, County Route 581, and a short section of the New Jersey Turnpike cross the township. On September 1, 2021, an EF3 tornado from the remnants of Hurricane Ida damaged or destroyed multiple homes here.

Where Roofs Meet Walls

A roof-to-wall joint occurs anywhere a sloped roof runs into a vertical surface. On a typical Harrison house you might find them at:

The side walls of dormers on older Mullica Hill homes
The front wall above a porch roof
The wall where a lower garage roof meets a two-story section on newer homes
The sides of a chimney
Additions tied into the original house

Each one depends on several pieces working together.

Step flashing

Individual L-shaped pieces of metal, one per shingle course, woven in so each piece laps over the one below. One leg lies on the roof under the shingle; the other runs up the wall.

Counterflashing or siding overlap

The vertical leg of the step flashing has to be covered so water running down the wall cannot get behind it. On siding, the siding laps over it; on brick, counterflashing is set into the mortar.

Kickout flashing

At the bottom of a roof-to-wall joint, where the roof edge ends but the wall continues down, a small angled piece called a kickout turns water away from the wall and into the gutter. Without it, water pours down the face of the wall at that corner.

Housewrap and wall details

Behind the siding, a weather barrier should lap over the step flashing so water that gets behind the siding is directed out rather than in.

Why These Joints Fail

On older homes

Older Mullica Hill houses often have steep roofs, dormers, porches, and brick chimneys, frequently on board decking and sometimes with more than one layer of shingles. Over decades, flashing at these joints has often been patched with roofing cement rather than replaced. When siding was replaced, the old step flashing may have been left behind, cut short, or not re-integrated with the new wall. Cement cracks, and water gets in.

On newer homes

Newer neighborhoods may have roofs approaching their first replacement, and installation issues sometimes surface: step flashing installed as one long strip instead of individual pieces, siding pulled tight to the roof so water wicks behind it, or kickout flashing left out entirely. A missing kickout often shows up as stained, swollen, or rotting siding and trim below the bottom corner of a roof-to-wall joint, sometimes with interior water damage behind it.

How Roof-to-Wall Joints Are Rebuilt

Shingles along the joint are removed, and siding is loosened or removed as needed to expose the old flashing.
Old flashing and cement are taken out, and the deck and wall sheathing are checked for rot. If more damage appears than expected, we stop and explain before continuing.
New step flashing is installed piece by piece with each course of shingles.
A kickout is installed at the bottom where needed.
Siding is reinstalled with proper clearance above the roof surface, or counterflashing is set into mortar on brick.

A lasting roof flashing repair rebuilds the layers rather than covering them with sealant. We inspect each joint before quoting. When a joint involves a chimney, masonry issues are covered on our Harrison Township chimney repair page, and when siding is involved, our siding repair page for Harrison Township explains that side.

Signs of a Failing Roof-to-Wall Joint

Many wall-joint problems can be spotted before they cause major damage. Inside, look for stains on walls or ceilings just below where a lower roof meets a taller wall, peeling paint near the tops of windows in that area, or a musty smell in a closet that backs onto the joint. Outside, look from the ground for siding that is darker, swollen, or soft at the bottom corner of a roof-to-wall joint, which often signals a missing kickout. Caulk or roofing cement smeared along the joint is a sign that someone has tried a quick fix before. On older Mullica Hill homes, check where dormer walls meet the main roof and where porch roofs meet the front wall. On newer homes, look closely at garage-to-house junctions and any spot where a single-story roof runs into a two-story wall. If you see any of these signs, an inspection can determine whether the flashing needs to be rebuilt before water damages the wall framing.

What Not to Do

It can be tempting to run a bead of caulk along a leaking wall joint. Caulk may slow a leak briefly, but it does not redirect water the way overlapping flashing does, and once it cracks, it often traps water behind it. Avoid climbing onto the roof to apply sealant yourself; roof-to-wall joints are often on steep sections or above porches where footing is poor.

Storms and Open Land

Mullica Hill and the rest of the township remember September 2021, yet the everyday threat is the ordinary thunderstorm or nor’easter sweeping across farmland. Those blows go after shingle edges and any loose metal at a wall joint. Your part afterward: photos from the lawn, no ladders. Ours, if the roof is open: a temporary tarp, then the permanent repair once things dry. Insurance questions belong to your carrier; we supply pictures and an estimate if you need them.

Other Common Repairs

Shingles: wind-damaged and missing shingles are replaced and woven into the existing courses. Missing shingles repair should be prompt. Older shingles may crack when lifted, and weathered colors fade or are discontinued, so a repair may look different at first.
Pipe collars: cracked rubber boots are replaced in a typical roof vent leak repair.
Valleys: debris and heavy runoff wear valley shingles.
Skylights: leaks may come from curb flashing, unit seals, or condensation.
Ice dams: attic heat can melt snow that refreezes at the eaves, backing water under shingles.

Tracing a Leak

A wall-joint leak usually announces itself on the interior wall just below the joint, but water can also travel along framing and appear somewhere else. We trace from the stain upward and confirm from the attic or a nearby access point when safe. Condensation, a bath fan venting into the attic, plumbing, AC drain lines, and window leaks can look similar, so we rule out those possibilities before recommending roof leak repair.

Historic Areas

If your home is in a historic area of Mullica Hill, check with the township about any requirements for exterior work before choosing materials.

The Free Inspection

During the no-cost inspection, each wall joint is examined on its own terms. Is the step flashing in individual pieces or one long strip? Does the siding sit high enough above the shingles to avoid wicking? Is there a kickout at the bottom corner? Then the rest of the roof gets its turn, and the attic too if it is safe to enter. Expect a plain explanation, whatever photos we could take, and a written roof repair estimate. Structural questions go to engineers and claims to adjusters; this is the roofer’s view.

Repair or Replace?

Rebuilding one bad wall joint on a roof that still has years left is money well spent. The case for a new roof only builds if the shingles are spent across the board, leaks surface in new rooms season after season, soft decking turns up in more than one place, or earlier overlays have left too many layers. Your own plans for the house weigh in as well. Replacement details are on our Harrison Township roofing contractor page.

Harrison Township Roof Repair FAQs

Who repairs roofs in Harrison Township, NJ?

Monarch Roofing & Construction repairs residential roofs throughout Harrison Township in Gloucester County, including Mullica Hill, Richwood, and Ewan. Phone or text (551) 241-0470.

What is kickout flashing?

A short angled piece of metal at the foot of a roof-to-wall joint that steers water into the gutter instead of down the face of the wall.

Why is the siding rotting below my garage roof?

A missing kickout can send water down the wall at that corner.

Can caulk fix a roof-to-wall leak?

Only briefly. Rebuilding the step flashing is the lasting repair.

Why does my dormer leak in wind-driven rain?

Dormer side walls depend on step flashing. When it is cement-patched or was disturbed during siding work, wind can push rain behind it.

Do newer homes have flashing problems too?

Sometimes. Step flashing installed as one long strip, siding set too tight to the roof, or a missing kickout can all cause leaks on newer houses.

Will you need to remove my siding?

Often a section near the joint must be loosened or removed so the flashing can be rebuilt properly, then it is reinstalled.

Is the inspection free?

Yes, with a written estimate. It is not an engineering or insurance inspection.
