Roof Replacement
Roof Replacement Rahway, NJ
A Rahway 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. Dial (908) 562-6861 to talk with a local roofer about replacement.
Replacement makes sense once the whole roof surface is failing, not just a single area. 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.
What sits under the shingles matters as much as the shingles themselves. Underneath are the deck boards or sheathing, the underlayment, ice and water shield at the eaves and valleys, metal drip edge, flashing at every wall and chimney, pipe boots and the vents that let the attic breathe. Leaving old flashing or rotten boards in place undercuts the new roofing laid over them.
Before you call, try to find out roughly how old the roof is, whether it has been overlaid before and where any leaks have shown up. 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 Rahway roofer may also recommend roof installation or shingle roof replacement.

Call nowThe process
What happens during a roof replacement
A full replacement follows a set order from the deck up.
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. You should come away with a written scope that lists materials, layers to remove and who pulls the building permit most towns require.
Remove the old layers
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.
Check the sheathing
Any soft, cracked or water-stained sheathing is cut out and replaced, and loose boards are renailed.
Build the roof system
The new layers go on in order: drip edge, ice barrier, underlayment, starter course, step and counter flashing, vents and then the shingles or panels. 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
What a roof replacement includes
Underlayment
New underlayment goes over the whole roof and self-sealing ice barrier goes where water collects if wind ever lifts a shingle.
Flashing replacement
Flashing at walls, chimneys, skylights and vents is replaced with new metal so the weak points match the new roof.
Roof vents
Ventilation is reworked so intake and exhaust are balanced to keep heat and moisture out of the attic.
Sheathing replacement
Soft or rotted plywood, OSB or plank boards are replaced so the roof has a solid base.

Reroofing Rahway, NJ
In the trade, reroofing simply means roofing a house that already has a roof, as opposed to roofing new construction. Most codes cap shingle roofs at two layers, so a house that already has two must be stripped before reroofing. A tear-off costs more labor, but it is the only way to see and fix what is under the old roof.
When you talk with a Rahway roofer about reroofing, ask how many layers are on the house now and how they will confirm it. Ask what happens to the existing flashing and pipe boots, because reusing them is a common shortcut.

Roof Tear Off Rahway, NJ
Tearing off a roof means scraping away the shingles, felt and nails until only the sheathing is left. A dumpster is placed near the drop zone, and tarps cover beds, patios and anything that could catch falling debris.
Once the old roof is gone, every soft or rotted board is out in the open. 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 Rahway, NJ
Under every roof is a deck of plywood, OSB or spaced boards that holds the nails and carries the load. 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. 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.

How the weather here affects roofs around Rahway
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, 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 Rahway, NJ have the roof checked in the fall and again after the snow melts.

Common questions about roof replacement
What time of year is best for roof replacement?
Moderate temperatures and dry days make for the smoothest replacement. 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. Steep slopes, multiple layers, a lot of decking repair or a complex roof with many valleys and dormers can stretch that out.
How do I know if I need a new roof or just a repair?
That depends on whether the damage is isolated or the roofing is worn out everywhere. A localized problem on a roof with plenty of life left is usually worth repairing. Curling, granule loss on most slopes, repeated leaks or two existing layers usually point to replacement.
Can a new roof go over the old one?
An overlay is allowed in many places if there is just one layer, but never on top of two. Even when it is allowed, an overlay hides the deck, keeps old flashing in place and adds weight to the framing.
Do I need to be home during a roof replacement?
Being home is optional, though you should be available by phone. The roofer may need to ask about decking repairs or an unexpected issue once the old roof is off.
