Roof Repair Services in Mountainside, NJ

Shingles get the blame, but most roof leaks actually come in at the joints, the places where a roof meets a chimney, a wall, a dormer, a vent, or another slope. Metal flashing is what guards those joints. Monarch Roofing & Construction handles roof repair in Mountainside, NJ, and this page serves as a field guide to the flashing on a typical house: what each type does, how it fails, and what fixing it involves. We also repair limb and wind damage, moss-lifted shingles, valleys, pipe collars, and ice dam damage. The inspection is free and the estimate is written. Call or text (551) 241-0470.

Mountainside is a borough of about 7,000 residents on four square miles in Union County, bordered by Summit, Springfield, Westfield, Berkeley Heights, and Scotch Plains. Part of the Watchung Reservation, including Lake Surprise and the Watchung Stables, lies within it, and local zoning limits commercial development along Route 22. Its roughly 2,600 homes sit on many tree-lined streets, some on exposed slopes, which means leaves, limbs, shade, and wind all play a part in how roofs here age.

A Field Guide to Roof Flashing

Step flashing

These are small bent pieces of metal, one per course of shingles, used wherever a sloped roof runs into a vertical surface: a dormer side, a second-story wall, the flank of a chimney. Each overlaps the piece below it and tucks up behind the siding or into the masonry.

How it fails: pieces missing or too short, siding replaced without restoring them, corrosion over time.

Repair: remove shingles along the wall, install new step flashing course by course, and reshingle.

Counterflashing

Metal set into a mortar joint on a chimney or masonry wall, folded down over the step flashing so water cannot run behind it.

How it fails: mortar erodes and the counterflashing pulls out; tar smeared over the gap cracks.

Repair: cut a fresh joint, install new counterflashing, and seal the top edge.

Apron and head flashing

A single piece that laps over the shingles below a chimney front, a dormer window, or any wall the roof runs into from above.

How it fails: lifted edges, corrosion, or siding installed without lapping over it.

Repair: reset or replace the apron so it sheds onto the shingles below.

Crickets

A little peaked mini-roof built on the high side of a wide chimney, it parts the flow of water so it runs around the chimney instead of pooling against it.

How it fails: missing entirely on many chimneys, or its own flashing has failed. Without one, water and leaves pile up behind the chimney.

Repair: build and flash a cricket where needed.

Valley flashing

Metal or membrane lining where two slopes meet.

How it fails: worn through, punctured by nails placed too close to the center, or buried under debris.

Repair: replace damaged sections or reline the valley.

Kickout flashing

This is a short piece of bent metal at the lowest point of a roof-to-wall joint, angled to turn the water out into the gutter.

How it fails: often missing altogether, sending water into the wall at that corner.

Repair: install a kickout and repair any damaged siding or sheathing behind it.

Vent and pipe flashing

Boots or collars around plumbing stacks and exhaust vents.

How it fails: rubber cracks with age and sun; metal corrodes.

Repair: replace the boot, a routine roof vent leak repair.

Skylight flashing

A kit of pieces around a skylight curb.

How it fails: loose or corroded pieces, worn seals; condensation on cold glass can also mimic a leak.

Repair: reflash the curb or address the unit’s seals after confirming the cause.

Why Sealant Is Not Flashing

Caulk and roofing cement are fine for sealing a nail head or the top edge of counterflashing. They are not flashing. Sealant stiffens and splits as temperatures swing, freeze-thaw cycles speed that along, and a thick smear of it hides whatever is going on beneath. The durable fix replaces or resets the metal itself, and because softened wood may be lurking under a failed joint, we look closely before we price it. For chimney masonry, see our Mountainside chimney repair page.

How Flashing Ages

Flashing does not usually fail all at once. Metal corrodes slowly, especially where water sits or debris collects. Sealant at the top of counterflashing dries out over several winters. Mortar around chimney flashing erodes a little each freeze-thaw season. Siding gets replaced and step flashing gets disturbed. Each change opens a small gap, and small gaps become leaks. That is why flashing deserves a look every couple of years and after major storms, even when nothing is leaking yet.

When Flashing and Siding Meet

Much of the flashing on a house is partly hidden behind siding or trim. Step flashing along a wall, apron flashing below a dormer window, and kickout flashing at the bottom of a wall joint all depend on the siding lapping over them correctly. When siding is replaced, those pieces can be cut short, bent, or left out. If your leak began within a season or two of new siding, the flashing behind it is a prime suspect. In some cases, siding has to be removed near the joint to repair the flashing properly; our Mountainside siding repair service can handle that part.

Living Near the Watchung Reservation

Leaves, needles, and limbs

Homes near the reservation and on wooded streets collect leaves, needles, and branches. Storms can drop limbs that crack shingles and dent gutters. Clear gutters each fall and look the roof over after major storms. Our Mountainside gutter cleaning service can handle the gutters.

Shade and moss

Slopes under heavy shade dry slowly, and moss and algae take hold. Moss lifts shingle edges and holds moisture; trimming back overhanging branches, done by a tree professional, lets roofs dry.

Wind on exposed slopes

Homes on exposed slopes take more wind, which lifts shingle edges and ridge caps first. Creased shingles have lost their seal even if they lie flat. Repairs replace damaged shingles and caps and secure edges.

A Flashing Checklist You Can Do From the Ground

With binoculars, walk around the house and look at:

The base of each chimney: is there metal stepping up its sides, or just a band of black tar?
Dormer sides: can you see a neat line where siding meets roof, or gaps and stains?
The bottom of each roof-to-wall joint: is there a small angled piece of metal sending water into the gutter?
Vent pipes: are the collars intact, or cracked and curling?
Valleys: clear, or packed with leaves?

Note anything that looks off and take a photo. You do not need a ladder for any of this.

Ice Dams

Winter adds ice to the list. Warmth leaking into the attic melts snow from below; the meltwater freezes again at the cold overhang and backs up beneath the shingles. Ventilation, insulation, and leak barrier at the eaves are the defenses, and after a leak we repair the edge and point out what in the attic is feeding it.

How We Trace a Leak

Since flashed joints are the usual culprits, we start with the ones sitting above and uphill of the stain, the chimney, wall seams, dormers, vents, skylights, and valleys, and use the attic, when reachable, to follow the water’s path. Plumbing, windows, and condensation are ruled out along the way.

Shingle Repairs

Where a limb has cracked shingles or a gust has creased them, new pieces go in, woven under the course above. Neighboring shingles on older roofs can be brittle and split, and a new patch looks fresher than the weathered roof for a while; you will see the nearest product before we begin.

Repair or Replace?

One failed joint on a roof that is otherwise healthy is a repair, and often a modest one. Wear across every slope, joint after joint failing, layers stacked up, or a soft deck point toward replacement, which would bring new flashing throughout and balanced ventilation. Our Mountainside roofing contractor page covers replacement.

The Free Inspection

The visit is organized around the joints: every piece of flashing gets examined before we move on to the shingle field, peak, edges, valleys, and gutters, and the attic gets a look if it can be reached. Afterward you hear which joints are sound and which are not, see photos when helpful, and receive a written estimate. Treat it as a contractor’s opinion; engineers and insurance adjusters perform separate kinds of inspections.

Mountainside Roof Repair FAQs

Who repairs roofs in Mountainside, NJ?

Monarch Roofing & Construction provides roof repair in Mountainside, including all types of flashing, limb and wind damage, moss, valleys, vent boots, and ice dams. Call or text (551) 241-0470.

What is the difference between step flashing and counterflashing?

Step flashing is woven with each shingle course at a wall or chimney; counterflashing is set into the masonry and folds down over it.

Why does water collect behind my chimney?

Wide chimneys without a cricket trap water and leaves on their uphill side. Adding a cricket diverts the flow.

What is kickout flashing?

Think of it as a little deflector at the foot of a wall joint; without one, the water running down that joint heads straight into the wall.

Is the inspection free?

Yes. The inspection and written estimate cost nothing.

Do you tarp roofs after storms?

We do. A tarp can go over the damage until permanent repairs are made, and photos plus a written estimate from us can support the claim your insurer evaluates.

How often should flashing be checked?

Every couple of years and after major storms is a reasonable rhythm, even when nothing is leaking.

Do you repair flashing behind siding?

Yes. When flashing behind siding needs replacement, we remove and reinstall the siding near the joint as part of the repair.

How do I schedule?

Call or text (551) 241-0470, email monarchroofingnj@gmail.com, or book online.

Can tar fix my flashing leak?

Only temporarily at most effective. Replacing or resetting the flashing is the lasting repair.
