Headwall flashing
Headwall metal at the top of a slope is replaced and covered by the siding or counter flashing.
A Montville roofer can stop leaks where the roof meets a wall, dormer, skylight or edge by renewing the flashing at that joint, woven correctly with the shingles and tucked behind the siding. Call (862) 420-3039 to reach a local roofer.
Flashing is the thin metal that seals every place the roof surface is interrupted. The main types are step flashing at sidewalls, apron flashing at headwalls, counter flashing over the top, kickouts at the bottom of walls, valley metal and drip edge at the edges. A single missing or loose piece is enough to send water behind the shingles or into the wall.
Flashing leaks are sneaky because the water often runs into the wall instead of the attic. A missing kickout is a classic example: water running down the roof edge pours behind the siding at the bottom of the wall, and the rot shows up later as soft trim, stained siding or a damp window below. Catching it early keeps the repair to the flashing instead of the wall.
A bead of sealant along a joint is a warning sign, not a repair. Sealant smeared where flashing should be dries and cracks in a few seasons, and it can trap water instead of shedding it. Proper flashing sheds water by gravity and lapping, so it keeps working even after any sealant ages.
If the problem goes deeper than it first looked, a Montville roofer may also recommend chimney flashing repair or roof leak repair.

The roofer checks the joint from the roof and the attic, looking for missing pieces, rust, face nails and caulk hiding a gap. Probing the wall below shows whether water has reached the sheathing.
The shingles next to the wall come up, and the lowest siding courses come off to expose the flashing. Working the new pieces in correctly depends on access behind the siding.
New step flashing is installed one piece per shingle course, each lapping the one below, with a kickout diverter at the bottom. Each piece is nailed through the roof side only, so the wall and roof can move independently.
On masonry walls, counter flashing is set into a cut joint; on framed walls, the housewrap and siding cover the flashing. Siding pressed tight to the shingles stays wet and rots.
Damaged drip edge is renewed so water drips clear of the fascia. Correct laps at the edges keep water out of the fascia and soffit.
Headwall metal at the top of a slope is replaced and covered by the siding or counter flashing.
Edge metal is renewed along the roof perimeter to protect the deck edge.
Missing kickout diverters are installed at the base of sidewalls to steer water into the gutter.
Cap flashing on masonry is reset into the mortar joint without relying on caulk alone.
Sidewall flashing is rebuilt one course at a time behind the housewrap.
Roof flashing repair ranges from resetting a single loose piece to rebuilding a full sidewall. Some repairs take an hour at one corner; others mean opening a whole wall joint and replacing the metal course by course. Ask the roofer which kind of repair your joint needs.
The metal used should suit the house. Copper, galvanized steel and aluminum all show up on roofs, and each has spots where it works best. Dissimilar metals touching each other corrode, so repairs should match existing flashing or be separated.
Valleys are the gutters of the roof surface, collecting water from both sides. In an open valley, a band of metal stays exposed down the center, while in a closed or woven valley the shingles cover the valley and the underlayment beneath does the heavy lifting. A peel-and-stick underlayment down the valley is the backup layer in both styles.
Valley leaks often come from debris, worn shingles or nails driven too close to the center. Small installation details, like clipping the upper corners of the cut shingles, keep water flowing down the valley instead of across it. Valley repair usually means removing the shingles along the valley, replacing the membrane and metal and reshingling with the right cuts.
Around Montville, flashing leaks tend to show up wherever a roof runs into a wall, a dormer or a skylight. Across Montville and nearby communities including Lake Hiawatha, Towaco, Boonton and Pine Brook, the age of the house and the number of roof-to-wall joints decide how much flashing work is likely, and each of those joints is a place worth checking.

Cold winters bring snow, ice and a long stretch of freezing nights. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, which is how ice dams form and back water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Montville, NJ have the roof checked in the fall and again after the snow melts.
Small roof problems caught early usually stay small repairs.
Roofers in Montville know the roof types and weather wear common in local homes.
Ask the roofer about the cause, the options and the estimate before work starts.
