Signs It Is Time to Replace

Before talking about flashing, settle whether the roof as a whole needs replacing. That case is made by condition across the roof, not a single symptom. Shingles that are bald, cupped, curled, or cracked over most of the slopes; grit piling up in gutters; leaks that keep showing up in new rooms or reopen after repairs; storm damage over a large area; decking that dips or flexes; two layers already up there; a repair invoice nearly every season. Age informs the picture without deciding it.

A leak at a single chimney or vent on an otherwise healthy roof is usually a flashing repair, not a reason for a new roof. Replacement makes more sense when the shingles themselves are failing broadly, when brittle material makes repairs messy, when the deck is compromised in several places, or when repair costs add up over time. Your own timeline in the house counts as well. When a single joint is the culprit, the Mount Olive roof repair page explains how we chase it down.

Why Joints Leak

A shingle field is good at shedding water as long as water runs straight downhill over overlapping pieces. Joints interrupt that flow. Wherever the roof meets something vertical, like a chimney or a wall, or something that pokes through, like a pipe, or another slope, like a valley, water is forced to turn a corner. Flashing is the metal or membrane that guides it around that corner. When flashing is missing, rusted, loose, or sealed over with caulk instead of properly installed, water finds the gap.

Flashing also tends to wear out on a different schedule than shingles. Sealants dry and crack. Metal corrodes or gets bent. Rubber pipe collars split in the sun. On a replacement, reusing old flashing under new shingles is one of the most common shortcuts, and one of the most common reasons a new roof leaks. On our full replacements, roof flashing replacement is standard.

Chimney Flashing

A chimney needs two layers working together. Step flashing, individual L-shaped pieces, is woven into each course of shingles along the sides of the chimney. Counter-flashing is set into the masonry, usually cut into a mortar joint, and laps down over the step flashing so water running down the brick cannot get behind it. The uphill side often gets a cricket or saddle on wider chimneys to split the water around the chimney rather than letting it pond against the brick. The downhill side gets an apron.

If the chimney masonry is crumbling, new counter-flashing has nothing solid to grip. That is why we look at mortar, crown, and brick during the estimate. If repairs are needed, our chimney repair team can do them so the flashing goes onto sound masonry.

Roof-to-Wall Flashing

Where a roof runs into a wall, such as at a dormer cheek, a second-story wall above a porch, or an addition, step flashing is woven into the shingles and tucked behind the siding or under the wall’s weather barrier. At the bottom of that wall, a kick-out flashing turns water outward into the gutter. Without a kick-out, water running down the step flashing can pour straight down behind the siding and into the wall. Installing these properly sometimes means lifting or removing the bottom courses of siding and resetting them afterward.

Where a roof meets a wall at its top edge, as with a shed-style addition, a headwall flashing covers the joint and laps under the siding above.

Pipe and Vent Flashing

Plumbing vent pipes, exhaust vents, and other penetrations get new boots or metal flashing that sit under the shingles above and over the shingles below. Rubber collars on older boots crack with age and sun; replacing them is part of a full job. While we are there, we check that bathroom and kitchen exhaust fans actually vent through the roof rather than into the attic.

Valley Flashing

A valley is where two slopes meet and send their water into the same channel. Valleys carry far more water than any other part of the roof and often collect leaves. During replacement, valleys get self-adhering ice and water protection where required, and then a valley treatment, either open metal or a woven or cut shingle valley depending on the product and design, that carries water down efficiently.

Skylight Flashing

Skylights get flashing kits designed for the unit. If a skylight is old, cloudy, or has leaked before, replacing it while the roof is open is far simpler than cutting into a new roof later.

Edge Flashing

Drip edge along the eaves and rakes keeps water off the fascia and directs it into the gutters. At the eaves, it works together with the ice and water protection and the starter course to seal the bottom of the roof.

The Rest of the New Roof

Metal at the joints is only half the story. Around it, a full tear-off rebuilds everything else: old roofing stripped in the areas the scope names, every board checked, soft sheathing replaced once you have seen it and agreed, a synthetic underlayment over the wood, sticky leak barrier along the gutters and down the valleys and around penetrations where code or the maker asks for it, a starter row, the main shingles nailed to the maker’s pattern, ridge cap, and an attic airflow plan built around your space. For most sloped roofs that means laminated architectural shingles; the flat three-tab style is available too. Slate is possible once the rafters have been judged up to the weight. Cedar works where it can dry. Nearly flat porch or addition roofs get a rubber, thermoplastic, or modified-asphalt membrane, with its edges turned up and flashed where it meets a wall.

How the Job Runs

Day zero is the inspection: shingles, attic, and a close look at every chimney, wall, pipe, valley, and skylight. A written scope follows, naming each flashing location individually. You pick a product; the permit question gets answered and assigned. When the crew arrives, tarps go down, the old roof comes off, the wood gets checked, you see anything that needs replacing, and the roof is rebuilt one joint at a time. At the end, containers leave, a magnet bar rolls the lawn, and you get a tour.

Hidden Damage at the Joints

A joint that leaked for years usually leaves a soft patch of sheathing behind, often right beside the chimney or along a dormer wall, even if the ceiling below never stained. Tear-off is when that shows up. You get to look at it and approve the price before new wood goes in. If the framing near an old leak has rotted, that is a matter for a structural professional, which we are not, and we will tell you plainly.

Weather and Flashing

Nor’easters and summer squalls drive rain sideways straight at the joints. Snow drifts against chimneys and walls, then melts into them. Ice packs in at the eaves. Each freeze-and-thaw cycle opens hairline gaps a little wider, and July sun dries caulk into brittle strips. Properly lapped metal, rather than a bead of sealant, is what survives that year after year.

Estimating Cost

Joints drive price more than most owners expect. One plain gable with a single vent pipe is a very different job from a roof with two chimneys, three dormers, a skylight, and four valleys. Beyond that, the figure reflects square footage, slope, old layers, the product, how easy the house is to reach, any rotten sheathing, fees, crew time, and dumping. It comes in writing after we have been up there; financing can be discussed at the same visit.

Paperwork

Mount Olive’s construction office decides whether a permit is required, based on your building and the scope of the job, and we agree with you in advance on who files. Coverage on shingles and membranes is written by each maker, varies by line, and usually assumes installation per their instructions. Our own installation terms are handed to you on paper.

Preparing

Cars out of the driveway, frames off upstairs walls, sheets over attic boxes. Plan for noise and give pets and kids a quiet corner. Rain or a rotten surprise can stretch the job, so the finish day is never locked.
