Service overview
Tile Roof Underlayment Replacement in Edison, New Jersey
Tile Roof Underlayment Replacement in Edison, New Jersey means removing the existing clay or concrete roof tiles, stripping the old tile underlayment down to the sheathing, and installing a new water-shedding membrane before the tiles go back on. The underlayment is the actual waterproof layer on a tile roof. Tiles shed most of the water, but wind-driven rain and ice dams push water sideways and upward, and the felt is what stops it from reaching your attic. When that felt is brittle, torn, or past 20 years old, leaks start showing up at valleys, ridges, and flashing points.
In Edison, most tile roofs we inspect are 18 to 30 years old, and the underlayment has failed long before the tiles have. Concrete and clay roof tiles can last 50 years, but the roofing felt underneath them usually gives out at 20 to 25. That mismatch is why so many homeowners in Clara Barton, Menlo Park, and North Edison call us for tile roof underlayment repair Edison rather than a full tear-off. If you have been searching for tile roof underlayment replacement near me Edison, the answer is usually a lift-and-relay job, not a new roof.
Practical benefits
Why Replace the Underlayment Instead of the Whole Roof
Your tiles are probably fine. The felt underneath them is not. Replacing the underlayment lets you keep the expensive part of the roof and fix the part that is actually leaking.
Keep Your Existing Tiles
Clay and concrete roof tiles cost far more than the underlayment. We lift them, stack them on the roof, and reinstall the same tiles after the new membrane goes down. You keep the look, the color, and the warranty on the tile itself. On a typical 2,000 sq ft roof, that saves thousands compared to a full tile replacement.
Stop Leaks at the Source
Most tile roof leaks we find in Edison are not the tile. They are the failed underlayment at a valley, a ridge, or a copper flashing detail. Replacing the underlayment for tile roofs Edison-wide fixes the actual failure point instead of patching the symptom. We also replace any cracked roof tiles, slipped roof tiles, or broken roof tiles while the roof is open.
Extend Roof Life 20+ Years
A new synthetic underlayment under your existing tile adds 20 to 11 years of service life to the assembly. That is the difference between replacing the roof once and replacing it twice in your ownership. We use GAF and CertainTeed underlayment products rated for tile roof assemblies and installed to manufacturer spec.
Fix Ice Dam and Moss Damage
Edison winters bring freeze-thaw cycles that drive ice dams at the eaves, and our humid summers grow moss on north-facing slopes. Both push water under the tile and rot the felt. New underlayment plus a proper ice-and-water shield at the eaves and valleys stops that cycle. We also clear moss growth and treat the tile before it goes back down.
How service works
How Our Tile Roof Underlayment Replacement Process Works
Every job follows the same five steps. You get a written scope, a start date, and a crew that shows up when we say we will. Most residential jobs in Edison finish in two to four days.
STEP 01
Inspection and Scope
We walk the roof, check the attic from inside, and map every leak point, valley, and flashing detail. You get photos of the failed underlayment, a written scope, and a fixed price before we start. This usually takes 45 to 90 minutes on site. No charge for the estimate.
Tools and methods
Tools and Methods We Use on Tile Roof Underlayment Jobs
Tile Lifter and Pitch Hoist
Used to lift field tiles without cracking them and to move stacked tile on steep slopes. Keeps breakage under 2 percent on a typical job.
Tile Cutter and Tin Snips
Tile cutter handles clean cuts on replacement tiles. Tin snips shape copper flashing and aluminum flashing at valleys, chimneys, and sidewalls.
Roofing Harness and Fall Protection
OSHA-compliant fall protection on every roof. Required on all pitches above 6/12 and used on every job regardless of pitch.
Roofing Nail Gun and Chalk Line
Nail gun sets tile fasteners and underlayment fasteners to spec. Chalk line keeps underlayment courses straight and laps consistent across the slope.
Magnetic Sweeper
Run over the yard, driveway, and gutters at the end of every work day to catch stray nails and fasteners. Standard on every Edison job.
Caulking Gun and Roofing Sealant
Applies roofing sealant at ridge tiles, hip tiles, and flashing terminations. We use sealants rated for tile roof assemblies and NJ temperature swings.
GAF and CertainTeed Tile Underlayment Systems
We install underlayment to GAF and CertainTeed specifications for tile roof assemblies, including proper laps, fastening patterns, and ice-and-water shield at eaves and valleys. This keeps the manufacturer warranty valid and the assembly code-correct.
NRCA Tile Roof Installation Standards
We follow NRCA guidelines for tile roof underlayment, flashing, and fastening. That means correct headlap, correct fastener type and length, and correct flashing details at every penetration. It is the standard insurance adjusters and home inspectors look for.
Ice-and-Water Shield at Eaves and Valleys
Self-adhering membrane goes down at the eaves, valleys, and any low-slope section before the field underlayment. This is the detail that stops ice dams and valley leaks, which are the two most common water entry points on Edison tile roofs.
Attic-Side Verification
We inspect the attic before and after every job to confirm the leak is stopped and no new moisture is showing. Photos go in your file. This is how we verify the fix instead of assuming it worked.
Where this service fits
When Edison Homeowners Need Underlayment Replacement
A 1990s concrete tile roof in North Edison is leaking at the chimney after 25 years with no prior work.
We inspect the felt, confirm it is brittle and torn at the chimney, and quote a full slope underlayment replacement with new copper flashing and a chimney cricket. Tiles are lifted, stacked, and reset. Leak stopped, chimney detail rebuilt to current code, and the original tile kept. Total job time was three days, and the roof is set for another 25 years.
A homeowner in Menlo Park is selling and the buyer's inspector flagged the underlayment as past service life.
We provide a written scope and fixed price the same week, then complete the replacement before closing. Documentation includes before-and-after photos and the workmanship warranty for the buyer. The sale closed on schedule, the buyer got a documented new underlayment, and the seller avoided a price concession at the negotiating table.
A Clara Barton homeowner has three slipped tiles and a small ceiling stain after a summer storm.
We reset the slipped tiles, replace two cracked tiles, and find the felt at the valley is failing. We quote a partial underlayment replacement at the valley and the surrounding slope rather than the whole roof. Leak stopped for a fraction of a full replacement cost. We scheduled a follow-up inspection in 12 months to watch the rest of the felt.
A Raritan Center property manager needs underlayment replaced on a low-slope tile section before winter.
We schedule the work in October, lift the tile, install new ice-and-water shield and synthetic underlayment, and reset the tile with new fasteners. Crew works around tenant hours. Building is winter-ready, the property manager has documentation for the owner, and no emergency calls came in during the January ice storms.

How Tile Roof Underlayment Replacement Runs in Edison
Edison sits in Middlesex County with a mix of 1950s ranches, 1980s and 1990s subdivisions, and newer construction, and the tile roofs on those homes age differently. The older homes often have original concrete roof tiles with felt that is 25 to 35 years old and well past service life. The 1990s subdivisions typically have concrete tile with underlayment hitting the 20 to 25 year mark right now. Our winters bring freeze-thaw cycles that drive ice dams at the eaves, and our humid summers grow moss on north-facing slopes. Both shorten underlayment life. We pull permits where required and work to New Jersey Home Improvement Contractor License standards on every job. If you need to replace underlayment on tile roof in Edison New Jersey, expect a two- to four-day job, a written scope, and a crew that shows up at 7 a.m. and cleans up before dark.
North Edison
Mostly 1980s and 1990s subdivisions with concrete tile roofs now hitting the 20 to 25 year underlayment window. We do a lot of full-slope replacements here.
Clara Barton
Mix of older ranches and capes with original clay tile. Felt is often 30+ years old and brittle. Valley and chimney leaks are common.
Menlo Park
Historic and mid-century homes with varied tile profiles. We keep Ludowici and MCA color matches on hand for these roofs.
Raritan Center
Commercial and industrial buildings with low-slope tile sections. We schedule work around tenant hours and building access rules.
South Edison
Many 1960s and 1970s homes with concrete tile and original felt. Ice dam damage at the eaves is common after hard winters.
Freeze-thaw winters with ice dams at the eaves
Ice dams push meltwater backward under the tile and rot the felt at the eaves. We install ice-and-water shield at every eave and valley during replacement, and we check attic insulation since that drives the problem.
Humid summers and moss growth on north slopes
Moss holds moisture against the tile and lifts edges, letting water under the assembly. We remove moss growth by hand and treat the roof before resetting tile so it does not come back the next season.
Summer thunderstorms and nor'easters
Wind-driven rain pushes water sideways under the tile, which is exactly what a failed underlayment cannot handle. We see a spike in leak calls after every major storm and run 24/7 emergency response during those weeks.
Aging housing stock with original tile and felt
Many Edison tile roofs are on their second or third decade with the original underlayment. We inspect the felt on every estimate and tell you honestly whether it needs replacement now or can wait a few years.
Problems we solve
Tile Roof Problems We Solve With Underlayment Replacement
Most tile roof leaks in Edison trace back to the same handful of failures. Here is what we see most often and how we fix it.
Ceiling stains and attic moisture with no visible tile damage
We trace the leak with water testing and attic inspection, then replace the failed underlayment at the entry point and across the surrounding slope. If the felt is past 20 years, we quote the full slope replacement so you are not chasing leaks one at a time. Water is getting past the tile and through the failed underlayment. If you ignore it, the decking rots, insulation gets wet, and mold starts. Repair cost goes from hundreds to thousands once the deck is involved.
Leaks at valleys, chimneys, and sidewalls after heavy rain
We rebuild the detail from the deck up: new ice-and-water shield, new copper flashing, new underlayment, and reset tiles. For chimneys we add a cricket on wide stacks. This is the same scope we use on every tile roof underlayment replacement in Edison. These are the highest-volume water paths on the roof. Failed flashing and worn underlayment at these details leak every storm and get worse each season. Ice dams in winter push water even further under the assembly.
Moss growth and ice dams shortening roof life
We remove moss growth by hand, treat the roof, and install ice-and-water shield at the eaves and valleys during underlayment replacement. We also check attic insulation and ventilation, since poor insulation is a major ice dam driver in Edison. Moss holds water against the tile and lifts edges, letting water under the assembly. Ice dams at the eaves push meltwater backward under the tile and rot the felt. Both problems age the underlayment years faster than normal.
Slipped, cracked, and broken tiles exposing the felt
We reset slipped tiles, replace cracked and broken tiles with color-matched stock, and inspect the felt under every one. If the underlayment is still good, we fix just the tiles. If it is failing, we quote the replacement at the same visit. Every slipped roof tile and cracked roof tile leaves the underlayment exposed to UV and direct rain. The felt breaks down at those spots first, and the leak shows up inside months later. Small tile problems turn into full underlayment failures.
A practical standard for every visit.

Frequently Asked Questions About Tile Roof Underlayment Replacement
Still wondering?(732) 123 4567
Most residential jobs in Edison run $6,500 to $18,000 in 2026, depending on roof size, tile type, and how much flashing and decking needs replacement. A typical 2,000 sq ft concrete tile roof with moderate flashing work lands around $9,000 to $12,000. Steep pitches, slate roof tiles, and multiple valleys push the number higher. We give you a fixed written price before any work starts.
Every 20 to 25 years for standard roofing felt, and 25 to 30 years for premium synthetic underlayment. Edison's freeze-thaw winters and humid summers age the membrane faster than a dry climate, so we often see failure at 18 to 22 years on older roofs. If your tile roof is past 20 years and has never had the felt replaced, get an inspection before the next storm season.
Two to four days for most single-family homes in Edison. A simple gable roof with one valley can finish in two days. A complex roof with multiple valleys, dormers, and chimney flashing takes three to four. We start early, work full days, and do not leave your roof open overnight. If rain is in the forecast we tarp the exposed deck before we leave.
Edison Tile Roof Replacement does, and we have since 2015. We are a tile-specific contractor, not a general roofer, and we hold a New Jersey Home Improvement Contractor License with full liability and workers comp coverage.
