Roof Replacement
A new roof,
built in layers.
A roof is not shingles. It is the decking under them, the ice and water shield at the eaves, the synthetic underlayment, the drip edge, the flashing, and the ventilation that keeps the whole system dry from the inside. We replace every layer, install GAF Timberline HDZ shingles as a GAF Certified Contractor, and most North Jersey homes are finished in a day or two.

Why the layers matter
Shingles are the last
thing we install.
Most of the roofs we tear off in Bergen, Essex, and Morris County failed from underneath, not on top. Old felt paper tore during installation and let water reach the deck. There was no ice and water shield at the eaves, so twenty winters of ice dams rotted the first two feet of plywood. The attic had no real exhaust, so the shingles cooked from below and curled a decade early.
Our replacement fixes all of that. The deck is inspected sheet by sheet after tear-off and anything soft is replaced before a single nail goes in. GAF WeatherWatch ice and water shield covers every eave, valley, and penetration. Synthetic underlayment covers the rest of the deck. Then the HDZ shingles go on, with ridge venting cut and matched to soffit intake so the attic finally breathes.
The full system
What a Pro Gen roof replacement includes
Every item below is part of the base price, not an upgrade. It is how the GAF System Plus warranty is earned.
- 01
Complete tear-off to the deck
Every layer of old shingle and felt removed. We never roof over an existing layer, no matter how much faster it would be.
- 02
Deck inspection and replacement
Each sheet of plywood checked for rot, delamination, and loose fasteners. Soft sheets replaced with new CDX before underlayment.
- 03
GAF WeatherWatch ice and water shield
Self-adhering membrane on all eaves, valleys, around chimneys, skylights, and every pipe. This is what stops ice dam leaks.
- 04
Synthetic underlayment
Stinger or GAF FeltBuster over the entire deck. Far stronger than felt, does not tear in wind, and keeps the house dry if installation runs past dark.
- 05
New drip edge and flashing
Metal drip edge on every rake and eave, new step flashing at walls and chimneys, new pipe boots. Old flashing is not reused.
- 06
GAF Timberline HDZ shingles
Architectural shingles with LayerLock and the WindProven unlimited wind warranty when installed as a full GAF system.
- 07
Ridge ventilation
GAF Cobra ridge vent cut along the peak and balanced with soffit intake so hot, moist air leaves the attic instead of condensing on the deck.
- 08
Cleanup and final drone flight
Magnet sweep of the yard and driveway, gutters cleared, debris hauled the same day, and an aerial photo set of the finished roof.

Is it time?
Signs a roof is past repairing
A single leak is a repair. These are the signs that the whole system has reached the end and more patches will only delay the same decision.
Roof is 18 to 25 years old
Three-tab and early architectural shingles in New Jersey rarely get past this range. The asphalt dries out and granules let go all at once.
Curling or cupped shingle edges
The shingle has lost its flexibility. Wind will start taking them off in strips, usually during the worst storm of the year.
Granules piling in gutters and at downspouts
The protective surface is gone. Bare asphalt under it breaks down fast in sun and freeze cycles.
Leaks in more than one area
When flashing, valleys, and field shingles all fail within a year or two, the material itself is done.
Daylight or dark stains visible in the attic
Water has been reaching the deck for a long time. Plywood replacement is almost certain and the shingles above are not protecting it.
Neighbors with the same builder are replacing
Developments were roofed in the same month with the same material. If the house next door is being redone, yours is on the same clock.
What the days look like
From tear-off to finished roof
- 01
Protect the property
Tarps over landscaping, plywood against siding where ladders go, and a dump trailer positioned to catch the tear-off directly.
- 02
Tear off and inspect
Old roof removed to bare deck by mid-morning. Foreman walks every sheet and marks anything soft for replacement before we move on.
- 03
Dry it in
Ice and water shield, synthetic underlayment, drip edge, and new flashing. By this point the house is watertight even if shingles wait until tomorrow.
- 04
Shingle and ventilate
HDZ shingles installed to GAF spec, ridge vent cut and installed, new pipe boots and counter-flashing sealed.
- 05
Clean up and fly
Magnet sweep, gutters cleared, debris hauled. Drone photos of the finished roof sent to you along with the warranty registration.
How a Pro Gen roof gets built
Five steps. One crew.
Zero shortcuts.
Every photo below is from a Pro Gen job site. This is the same sequence your roof goes through.
01
02Full Tear-Off
Everything comes off, down to the deck. No layering new shingles over old problems.
03Deck & Ice Shield
Rotted plywood replaced, then ice and water shield at every eave, valley and penetration.
04Synthetic Underlayment
Heavy-duty synthetic barrier over the whole deck. Your roof is dried-in the same day.
05Shingles & Final Flight
GAF architectural shingles, ridge vent, cleanup, then a final drone pass you get to keep.
Most residential replacements are torn off, dried-in and shingled within one to two days.
Common questions
Roof Replacement questions
How long does a roof replacement take?
Most single-family homes in North Jersey are torn off and finished in one day. Larger homes, steep pitches, or heavy deck replacement can push it into a second day. The house is watertight by the end of day one regardless.
Do I need to be home?
Not during the work. We need access to the driveway and power for the compressors. Someone should be reachable by phone in case we find deck damage that changes the scope.
What is the GAF System Plus warranty?
A manufacturer-backed warranty available only through GAF Certified Contractors installing a full GAF system. It covers the shingles and accessories for 50 years and includes GAF coverage on our workmanship. We register it for you after the job.
Will you roof over my existing shingles to save money?
No. A second layer hides deck damage, adds weight the framing was not designed for, voids most manufacturer warranties, and shortens the life of the new shingles. Everything comes off.
How much decking will need replacing?
We cannot know until the old roof is off, which is why the estimate lists a per-sheet price for replacement up front. On a typical home it is zero to four sheets. Homes with long-term leaks or no ice and water shield can need more, and we photograph each sheet before replacing it.
Do you handle the permit?
Yes. Our office files the roofing permit with your town, pays the fee, and schedules the inspection. Permit requirements vary by municipality and we deal with all of them regularly.
