Underlayment
New underlayment goes over the whole roof and self-sealing ice barrier goes where water collects behind the roofing.

Roof Replacement Madison, NJ
A Madison roofing contractor can replace a roof that is too old or too damaged to patch, starting with a full tear-off and a check of the decking, with a written scope so you know exactly what is being replaced. Call (862) 431-0046 to reach a local roofer.
Most roofs reach the point of replacement through age rather than one dramatic event. Asphalt shingles lose their protective granules over the years, then dry out, curl, crack and stop sealing down, and a roof in that shape starts leaking in new places faster than anyone can patch it. The type of shingle and the number of layers already on the roof both shape when, and how, a replacement happens.
A new roof is really a system, and the shingles are the last layer of it. 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. Skipping any of those parts is how a brand new roof ends up leaking in its first heavy rain.
Ahead of the first conversation with a Madison roofer, note the age of the roof, any leak spots on ceilings and whether there might be two layers up there. If the attic is easy to reach, check for dark, damp boards or pinholes of daylight while standing only on framing.
Depending on what the roofer finds, roof replacement in Madison, NJ can go hand in hand with roof installation and shingle roof replacement.

Call nowThe process
The roof replacement process
Each step builds on the one before it, so the order matters.
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. A written scope spells out the roofing, underlayment, flashing and vents, and the contractor usually files the reroof permit.
Tear off the old roof
The crew protects landscaping and siding, then strips every layer of shingles, underlayment and old flashing down to the wood. Good crews open only what they can cover again before they leave.
Repair the decking
Any soft, cracked or water-stained sheathing is cut out and replaced, and loose boards are renailed.
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.
Clean up the site
Debris is hauled off and a rolling magnet sweeps the lawn, beds and driveway for nails. A final walk-through with you is the time to point out anything that looks off.
What is included
What a roof replacement includes
Ventilation
Ventilation is reworked so intake and exhaust are balanced to keep heat and moisture out of the attic.
Old roof removal
All old layers are stripped to the deck and hauled away which lets the crew see the decking.
Flashing replacement
Worn flashing and cracked pipe boots are replaced rather than reused so the weak points match the new roof.
Deck repair
Soft or rotted plywood, OSB or plank boards are replaced before anything new is nailed down.

Reroofing Madison, NJ
Reroofing is the general term for putting a new roof on an existing house, whether that means a full tear-off or, in limited cases, a single overlay. Building codes generally allow at most two layers of asphalt shingles, and an overlay is only an option when the existing roof is flat, dry and has a sound deck. A tear-off costs more labor, but it is the only way to see and fix what is under the old roof.
Before reroofing a Madison home, it is worth asking the roofer to check the layer count at the eaves or a vent opening. 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 Madison, NJ
During a tear-off, the crew strips the roof to bare wood using shovels and roofing forks, slope by slope. Old material is dropped into a dumpster or trailer while tarps and plywood guard the yard, windows and air conditioning unit.
The real value of a tear-off is what it reveals. 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 Madison, NJ
Roof decking, also called sheathing, is the layer of plywood, OSB or plank boards that everything else is nailed to. Years of small leaks or a damp attic can rot sheathing or make OSB swell and lose strength.
Rotted sections are cut back to solid wood and replaced, and spaced plank decks may get a full layer of new plywood or OSB. Ask up front how the roofer will handle and document any decking replaced, so there are no surprises.

Roof Replacement Near Me
In Madison, replacement requests come from older homes and newer ones alike: worn three-tab roofs on older houses and architectural shingle roofs that took a beating from wind or hail. Across Madison and neighboring communities such as Florham Park, Chatham, Summit and Morristown, 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.

How the weather here affects roofs around Madison
Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, building ice dams that push water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Madison, NJ have the roof checked in the fall and again after the snow melts.

Roof Replacement FAQ
How long does a roof replacement take?
For most single-family homes, the crew is on site for one to three days. Steep slopes, multiple layers, a lot of decking repair or a complex roof with many valleys and dormers can stretch that out.
When is the best season to replace a roof?
Mild, dry weather is ideal, which usually means late spring through early fall. Cold weather makes shingles brittle and slows the sealing process. If the roof is leaking now, a temporary fix can protect the house until replacement is scheduled.
Can a new roof go over the old one?
Building codes generally allow at most two layers of asphalt shingles, so an overlay is only possible on a roof with one layer and a sound deck. It also means reusing or working around the old flashing, which is where many leaks start.
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. The roofer may need to ask about decking repairs or an unexpected issue once the old roof is off.
How do I know if I need a new roof or just a repair?
The deciding factors are the age of the roof, how widespread the wear is and the condition of the deck. 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.
