What Is Tile Roof Replacement?
Tile roof replacement removes failing clay or concrete tile and worn underlayment to the deck and installs a new underlayment-and-tile system over a load-rated structure. It renews both the waterproofing layer beneath the tile and the tile covering itself.
What Tile Roof Replacement Do We Provide?

Newark Quality Roofing replaces 2 tile roof systems across Essex County: clay tile and concrete tile — for residential properties, with select commercial and civic buildings. Tile roof replacement strips the tile and the worn underlayment to the deck, verifies the structure carries the tile dead load, and installs a new underlayment-and-tile system, the work that resets a tile roof when the underlayment fails beneath tile that still has decades of service left.
Clay tile lasts 75 to 100-plus years and concrete tile 40 to 75 years, per the Tile Roofing Industry Alliance, against the InterNACHI life-expectancy chart listing clay and concrete tile at 100-plus years. The underlayment is the real service-life limiter, failing well before the tile, per the Tile Roofing Industry Alliance and This Old House, so a Newark Quality Roofing tile replacement renews the underlayment and flashing while salvaging or matching the tile profile.
- Clay tile roof replacement — Clay tile roof replacement installs natural clay tile that lasts 75 to 100-plus years, per the Tile Roofing Industry Alliance, on Mediterranean and Spanish-revival homes where the tile outlives the underlayment beneath it.
- Concrete tile roof replacement — Concrete tile roof replacement installs concrete tile that lasts 40 to 75 years, per the Tile Roofing Industry Alliance, and resists the freeze-thaw spalling and efflorescence that age concrete tile in the Essex County climate.
- Underlayment replacement under salvaged tile — Underlayment replacement under salvaged tile lifts and re-lays sound tile over a new underlayment, because the underlayment fails well before the tile, the real repair-vs-replace trigger, per the Tile Roofing Industry Alliance and This Old House.
- Tile-to-deck tear-off — Tile-to-deck tear-off strips clay or concrete tile to the bare sheathing, the work N.J.A.C. 5:23-6.4 requires because a tile roof cannot be roofed-over and the deck takes complete removal of the existing covering, per the NJ Rehabilitation Subcode.
How Do You Know If You Need Tile Roof Replacement?




- Interior leaks and ceiling stains under intact tile indicate failed underlayment rather than failed tile, because the underlayment fails well before the tile and is the real service-life limiter on a tile roof, per the Tile Roofing Industry Alliance and This Old House.
- Slipped, displaced, or sliding tile across the field indicates corroded fasteners and a deteriorated underlayment that no longer holds the tile course, per the Tile Roofing Industry Alliance, where the structural detail fails rather than the tile.
- Broken or cracked tile across more than 20 to 25% of clay or 15 to 20% of concrete crosses the contractor-consensus replacement threshold for a tile roof, per industry repair-vs-replace guidance, because tile cannot be patched and takes a matching-profile replacement.
- Spalling and surface flaking on concrete tile indicates freeze-thaw damage from Essex County winters, because Newark crosses the 32°F freezing point repeatedly with an average January low near 25.5°F, per NOAA 1991–2020 normals at Newark Liberty (EWR).
- Deteriorated valley, headwall, and chimney flashing under tile admits water at the transitions, because flashing seals the roof transitions that roughly 90 to 95% of leaks trace back to, an industry estimate attributed to the NRCA.
- A spongy or sagging roof deck under the tile indicates moisture-rotted sheathing from years of underlayment leakage, a structural condition that points toward full replacement rather than a tile-by-tile patch, per GAF inspection guidance.
- Daylight through the roof deck seen from inside the attic under a tile roof indicates holes in the decking and a failed underlayment, a sign that points toward replacement rather than a patch, per This Old House.
- A tile roof past 50 years with an original underlayment reaches the point where the underlayment outlives its service even as the tile holds, because clay tile lasts 75 to 100-plus years and concrete 40 to 75 years while the underlayment fails sooner, per the Tile Roofing Industry Alliance.

How Do Our Roofing Contractors Perform Tile Roof Replacement?

Newark Quality Roofing contractors verify the deck and framing carry the tile dead load and rate the underlayment before quoting a tile replacement, because tile is heavy and the structure carries the load while the underlayment, not the tile, sets the service life. Clay tile lasts 75 to 100-plus years and concrete tile 40 to 75 years, per the Tile Roofing Industry Alliance, and the underlayment fails well before the tile, per the Tile Roofing Industry Alliance and This Old House, so a Newark Quality Roofing assessment confirms structural capacity for the tile weight and dates the underlayment that drives the replacement. A tile roof cannot be roofed-over, so the assessment plans a tear-off to the deck, per N.J.A.C. 5:23-6.4.
Newark Quality Roofing matches the tile system to the building and the Essex County climate from 2 tile classes: clay tile and concrete tile. Clay tile lasts 75 to 100-plus years on Mediterranean and Spanish-revival homes, and concrete tile lasts 40 to 75 years, per the Tile Roofing Industry Alliance, and Newark crosses the 32°F freezing point repeatedly through winter with an average January low near 25.5°F, per NOAA 1991–2020 normals at Newark Liberty (EWR), driving the freeze-thaw spalling and efflorescence that age concrete tile. A Newark Quality Roofing tile replacement salvages sound tile and matches the profile of replacement tile to the existing roof, because tile cannot be patched and takes a matching-profile course.
Newark Quality Roofing strips the tile and the failed underlayment to the deck, repairs the sheathing, installs an ice barrier and a tile-rated underlayment, and re-lays the tile to manufacturer specification, the sequence that resets the service life on the underlayment that limits it. A full tear-off exposes the deck for inspection and replacement of plywood or OSB rotted under the old underlayment, the work the NJ Rehabilitation Subcode requires because a clay or concrete tile covering cannot be roofed-over and takes complete removal of the existing covering before new roofing, per N.J.A.C. 5:23-6.4. The IRC ice-barrier provision (R905.1.2) requires a self-adhering ice barrier from the eave to a point at least 24 inches inside the exterior wall line in ice-prone climates, per the International Residential Code.
What Residential Tile Roof Replacement Do We Provide?
Newark Quality Roofing replaces residential clay and concrete tile roofs across Essex County, re-roofing detached one- and two-family homes with no construction permit required for the roof covering. A complete tear-off and replacement of the tile covering on a detached one- and two-family dwelling counts as ordinary maintenance under N.J.A.C. 5:23-2.7 and requires no construction permit, no inspection, and no notice to the construction official, per the NJ Uniform Construction Code, while a structural change to rafters or trusses to carry the tile load triggers a permit.
A new roof recoups roughly 60 to 68% of project cost at resale, per Zillow analysis, so a tile replacement returns value at sale alongside the long tile life of 75 to 100-plus years for clay, per the Tile Roofing Industry Alliance. A Newark Quality Roofing residential tile replacement installs an ice barrier at the eaves per the IRC R905.1.2 ice-barrier provision, replaces decking rotted under the old underlayment, and contains debris with ground tarps and a magnet sweep for nails before leaving the property across Newark, East Orange, Bloomfield, Montclair, Belleville, Irvington, and Glen Ridge.

What Commercial Tile Roof Replacement Do We Provide?
Newark Quality Roofing replaces clay and concrete tile on Mediterranean, Spanish-revival, and civic buildings across Essex County, renewing the underlayment that limits service life under tile that outlives it. Clay tile lasts 75 to 100-plus years and concrete tile 40 to 75 years, per the Tile Roofing Industry Alliance, and the underlayment fails well before the tile on a civic tile roof the same way it does on a home, per the Tile Roofing Industry Alliance and This Old House.
On a commercial building, a tile roof replacement requires a permit under N.J.A.C. 5:23-2.7, because the ordinary-maintenance exemption covers only the repair of up to 25% of the total roof area in a 12-month period, per the NJ Uniform Construction Code. The NJ Rehabilitation Subcode requires complete removal of the existing covering, with no recover-over, because a clay or concrete tile roof takes a full tear-off rather than a roof-over, per N.J.A.C. 5:23-6.4. A Newark Quality Roofing assessment verifies the structure carries the tile dead load before the new tile is set.

What Are the Steps in Our Tile Roof Replacement Process?

- Structural and Underlayment Assessment
A Newark Quality Roofing technician verifies the deck and framing carry the tile dead load, dates the underlayment that sets the service life, and rates the tile and flashing condition before quoting the tile replacement, per the Tile Roofing Industry Alliance condition guidance.
- Written Estimate and Tile Selection
A Newark Quality Roofing written estimate sets the scope, labor, materials, and timeline and presents the tile options from 2 classes — clay tile at a 75 to 100-plus-year life and concrete tile at 40 to 75 years per the Tile Roofing Industry Alliance — before any work begins, per Integrity Home Exteriors documentation guidance.
- Permits and Tile Ordering
A Newark Quality Roofing crew files the construction permit when the job triggers one — a commercial roof, a structural change to carry the tile load, or work beyond ordinary maintenance under N.J.A.C. 5:23-2.7 — and orders matching-profile tile to arrive on the scheduled start date, per the NJ Uniform Construction Code.
- Tear-Off to Deck and Salvage
A Newark Quality Roofing crew strips the tile and the failed underlayment to the bare deck, salvages sound tile for reuse, and replaces deteriorated plywood or OSB, with complete removal of the existing covering required by N.J.A.C. 5:23-6.4 because a tile roof cannot be roofed-over.
- Ice Barrier, Underlayment, and Tile Installation
A Newark Quality Roofing crew installs the ice barrier from the eave to a point at least 24 inches inside the exterior wall line per the IRC R905.1.2 provision, applies a tile-rated underlayment across the deck, and re-lays salvaged and matching tile to manufacturer specification.
- Verification, Cleanup, and Warranty
A Newark Quality Roofing lead verifies the tile install against manufacturer specification, runs a magnet sweep for nails at cleanup, and issues a written workmanship warranty on the labor, separate from the manufacturer material warranty, per Integrity Home Exteriors verification and Owens Corning warranty guidance.
