Roof Replacement
Roof Replacement in Staten Island, NY
A roof replacement is more than installing new shingles. NYC Roof Co helps homeowners understand the condition of the existing roof, the materials required, and the complete roofing system before work begins.
Scope of work
What a Complete Roof Replacement Includes
The exact scope depends on the roof itself, but a full replacement generally moves through the following stages.
- 01
Existing roof tear-off
The existing roofing material is removed so the structure beneath it can actually be seen and evaluated.
- 02
Exposed deck inspection
With the roof stripped, the wood decking is inspected for deterioration, softness, movement or prior damage.
- 03
Damaged decking replacement
Sections of decking found to be compromised are replaced where required before anything is installed over them.
- 04
Ice and water protection
Self-adhering protection is applied at eaves, valleys and other areas where water intrusion is most likely.
- 05
Underlayment
Underlayment is installed across the deck as a secondary layer beneath the finished roofing material.
- 06
Flashing and roof penetrations
Chimneys, walls, vents, skylights and pipe penetrations are detailed as part of the roofing system.
- 07
Ventilation details
Intake and exhaust ventilation is addressed based on the roof design and what the attic space allows.
- 08
Finished roofing installation
The selected roofing system is installed, including starter, field material, hip and ridge details.
- 09
Final inspection and cleanup
The completed work is reviewed and the property is cleaned up, including removal of debris and fasteners.
Assessing the roof
Does Your Roof Need to Be Replaced?
Not every roofing problem calls for a replacement. Localized issues — a single flashing detail, one damaged area, a failed pipe boot — can often be repaired. The conditions below are reasons a homeowner may begin considering replacement instead, and they are examples rather than a diagnosis.
Widespread shingle deterioration
Granule loss, curling, cracking or brittleness spread across the roof rather than confined to one area.
Recurring leaks
Leaks that return after being addressed, or that appear in more than one part of the home.
Multiple damaged areas
Damage in several separate roof areas, which can make piecemeal repairs difficult to justify.
Deteriorated decking
Soft, sagging or water-affected decking discovered during an inspection or a previous project.
Aging roofing materials
Materials that have been in service a long time and are showing consistent, general wear.
Extensive flashing issues
Flashing and penetration details failing in multiple locations rather than at a single point.
A roof nearing the end of its useful condition
A roof whose overall condition — not its age alone — suggests continued repair has limited value.
Only an inspection of the actual roof can settle whether repair or replacement is the right path. Learn About Roof Repair.
Before pricing
See Your Roof Before We Price It
Our online roof estimator starts with your address and uses available aerial and property information to describe the roof you actually have.
Aerial measurements may be incomplete, out of date, or require manual verification — additions, dormers, tree cover and low-slope sections are common reasons. Final pricing is verified on-site against actual conditions.
- 01
Roof area
An approximate measurement of the roof surfaces detected on the property.
- 02
Pitch
The primary slope of the roof, which affects materials, labor and access.
- 03
Roof segments
How many distinct roof planes the property appears to have.
- 04
Geometry
Valleys, transitions and shapes that influence how a roof is built.
- 05
System requirements
The likely underlayment, waterproofing, flashing and ventilation a roof calls for.

Under the roofing
What Happens if the Roof Deck Is Damaged?
The roof deck is the wood surface the entire roofing system is fastened to. It stays hidden until the existing roofing is removed, which is why it is evaluated after tear-off rather than beforehand.
With the deck exposed, it can be checked for deterioration, softness, delamination or damage from previous water intrusion. Sections found to be compromised may require replacement before the new roofing system is installed, and any decking work should be documented as part of the final project scope.
