Roof Replacement
Roof Replacement Harrison, NJ
Replacing a roof in Harrison means stripping the old layers, fixing the deck and building a new roof system from the wood up, usually in one to a few days for a typical house. Dial (551) 348-3304 to talk with a local roofer about replacement.
A roof usually needs replacing when the roofing itself is worn out, not when one spot leaks. As shingles age they shed granules, turn brittle and curl at the edges, so leaks begin turning up in more than one spot at a time. Three-tab shingles tend to wear out sooner than heavier architectural shingles, and a roof that has already been overlaid once has no second chance.
The visible roofing is only part of what gets replaced. Below the surface sits plywood or OSB decking, felt or synthetic underlayment, ice barrier in the valleys and along the eaves, drip edge, step and counter flashing, pipe boots and ridge or box vents. A new surface over worn flashing or soft decking inherits the old problems.
It helps to write down when the roof went on, where stains have appeared and whether anyone has added a second layer. If the attic is easy to reach, check for dark, damp boards or pinholes of daylight while standing only on framing.
If the problem goes deeper than it first looked, a Harrison roofer may also recommend roof installation or shingle roof replacement.

The roof replacement process
Here is the typical sequence for replacing a residential roof.
Measure the roof
The visit includes a look at the roof surface, the attic side of the deck and the flashing, plus measurements for materials. Ask for the scope in writing, including how many layers come off, how deck repairs are counted and who files the permit.
Remove the old layers
Old shingles, felt and worn flashing are removed slope by slope so the deck is never left open for long. Only as much is torn off in a day as can be dried in by evening.
Repair the decking
Bare decking shows exactly where water got in, and damaged sections are swapped for new sheathing.
Install the new roof
After the underlayment and ice barrier, the crew sets starter, flashing, pipe boots and ventilation before the roofing itself goes down. Ridge vents are matched to soffit intake so the attic can breathe.
Final cleanup
Old roofing is hauled away and the property is swept with magnets for stray nails. Walk the job with the crew lead before they leave.
What is included
Parts of a full roof replacement
Full tear-off
Every existing layer comes off and is disposed of which lets the crew see the decking.
Deck repair
Rotted decking is swapped for sound wood before anything new is nailed down.
Ice barrier
Synthetic underlayment covers the deck, with ice and water shield at the eaves and valleys if wind ever lifts a shingle.
Ventilation
Ventilation is reworked so intake and exhaust are balanced so the attic stays dry in winter and cooler in summer.

Reroofing Harrison, NJ
In the trade, reroofing simply means roofing a house that already has a roof, as opposed to roofing new construction. An overlay may be allowed if there is only one layer and the deck is solid, but it hides the wood and adds weight. For most homes, a full tear-off is the better reroof because it exposes the deck and lets every piece of flashing be replaced.
When you talk with a Harrison roofer about reroofing, ask how many layers are on the house now and how they will confirm it. Also ask whether the new roof will get ice and water shield, new drip edge and new pipe boots, since those are easy places to cut corners.

Roof Tear Off Harrison, NJ
During a tear-off, the crew strips the roof to bare wood using shovels and roofing forks, slope by slope. The debris goes straight into a dumpster or dump trailer parked close to the house, with tarps protecting plants, decks and siding below.
Tearing the roof off is the only way to see the condition of the deck. Hidden rot around chimneys, skylights and valleys can be cut out, and old flashing that was buried under tar can be replaced.

Roof Decking Replacement Harrison, NJ
The decking is the wood surface between the rafters and the roofing, usually plywood or OSB on newer homes and plank boards on older ones. Long-term leaks, poor attic ventilation and condensation can leave it soft, delaminated or rotted, and nails will not hold in weak wood.
The crew cuts out bad sections, fastens new panels to the rafters and checks that edges line up for a flat surface. Since nobody knows exactly how much bad wood is under a roof until it is torn off, ask how deck replacement will be priced in the contract.

Roof Replacement Near Me
In Harrison, replacement requests come from older homes and newer ones alike: older homes that may still carry two layers of shingles or plank decking, and newer ones whose first roof is simply reaching the end of its life. Across Harrison and neighboring communities such as Newark, Kearny, North Arlington and East Orange, a roof replaced while the decking is still sound is a smaller, faster project, so it pays to have an aging roof looked at before it starts leaking in several places.

Roofs in this climate
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder 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. That is why roof repair in Harrison is busiest after a hard winter and before the next one.

Common questions about roof replacement
Is it okay to put new shingles over old shingles?
Code usually limits shingle roofs to two layers total. Even when it is allowed, an overlay hides the deck, keeps old flashing in place and adds weight to the framing.
Should I repair my roof or replace it?
That depends on whether the damage is isolated or the roofing is worn out everywhere. Isolated damage, like a lifted section or a single leak at a vent, is a repair job. When shingles are brittle and bald everywhere, or leaks keep moving around, replacement is the better investment.
Do I need to be home during a roof replacement?
You do not have to be there the whole time, but it helps to be reachable. Questions sometimes come up mid-job, such as how to handle rotted wood or a hidden vent.
What time of year is best for roof replacement?
Mild, dry weather is ideal, which usually means late spring through early fall. Shingle sealant strips bond best in warm sun, so very cold days call for extra steps. A roof that is actively leaking should not wait for perfect weather, since temporary repairs or a tarp can hold until the job starts.
How many days does it take to replace a roof?
For most single-family homes, the crew is on site for one to three days. Weather, the size of the crew and how much rot turns up all affect the schedule.
