About this service
What Roof Slate Replacement for Leaks Aberdeen WA Involves
Roof slate replacement for leaks Aberdeen WA is the targeted removal and reinstallation of cracked, slipped, or delaminated slate tiles, plus the underlayment and flashing beneath them, to stop water intrusion without tearing off the whole roof. We lift the surrounding courses, cut out the failed slate, inspect the felt and ice and water shield, then set a matching replacement slate and re-secure the course above it. On most Aberdeen homes that is a two- to six-hour job once we are on the roof.
Aberdeen sits in Grays Harbor County, where roughly 60 inches of rain a year and heavy moss growth chew through slate faster than almost anywhere in Washington. We see it constantly: a hairline crack opens after a hard freeze, water tracks down the underlayment, and a ceiling stain shows up weeks later. If you have been searching for roof slate replacement near me Aberdeen, we run moisture meter and infrared thermal camera scans first so we replace the right slates, not just the wet ones.

What's included
What Is Included in Slate Leak Replacement
Every slate replacement job covers the repair itself, the materials, and the testing. Add-ons like full underlayment replacement or gutter work are quoted separately and only if the inspection shows they are needed.
✓
On-roof leak inspection
Moisture meter, infrared thermal camera, and roof inspection drone scans to confirm exactly which slates and flashing are failing before we quote the repair.
✓
Matching slate replacement
We source replacement slate by size, thickness, and color to match your existing field, then set it with proper headlap and roofing nails.
✓
Underlayment repair
Failed underlayment beneath the slate is cut out and replaced with new roofing felt or ice and water shield, so the repair does not leak at the next storm.
✓
Flashing reseal
Step, apron, and counter-flashing around the repair is inspected and resealed with Henry Company or Sika sealant where it has pulled away.
✓
Water test and clean-up
A 15- to 20-minute hose test on the repair, an attic moisture check, and a magnet sweep of the yard for dropped nails before we pack up.
How it works
How Our Slate Leak Repair Process Works
01
Call and schedule
You call +13608991171 or book online. We ask what you are seeing, where the stain is, and how old the roof is. Same-day estimates are standard, and emergency calls get priority when water is actively coming in.
02
Roof inspection
We walk the roof with a moisture meter and infrared thermal camera, and fly a roof inspection drone over steep or fragile sections. That tells us whether the leak is a single slate, a flashing failure, or a valley problem before we quote anything.
03
Written scope and price
You get a clear scope: how many slates, what underlayment, what flashing, and the price. No surprise add-ons. Most single-slate repairs land between $350 and $900 depending on access and pitch.
04
Replace the slate
We set a ladder stabilizer and pitch hoist, lift the surrounding courses, cut out the failed slate with a pry bar and utility knife, replace the underlayment, and set the new slate with roofing nails from a roofing nail gun.
05
Water test and clean-up
We run a hose test kit over the repair for 15 to 20 minutes and check the attic side with the moisture meter. Then we magnet-sweep the yard for nails and walk you through what we found.
Tools & methods
Tools and Methods We Use on Slate Roofs
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Moisture meter
Reads moisture content in the attic decking and rafters so we know whether the leak is active or already dried.
Infrared thermal camera
Finds wet underlayment and hidden leak paths behind the slate that are invisible from the roof surface.
Roof inspection drone
Lets us survey steep or fragile slate fields without putting weight on tiles that could crack underfoot.
Pitch hoist and ladder stabilizer
Keeps our crew stable on pitched slate roofs and protects the slate from ladder pressure at the eaves.
Pry bar, utility knife, and roofing nail gun
The core slate replacement kit: lift the course, cut the failed slate, and re-nail the replacement and the course above it.
Hose test kit
Runs controlled water over the repair for 15 to 20 minutes so we can confirm the leak is actually stopped before we leave.
Real results
Before and after.
Ceiling Stain From Two Cracked Slates
Before
A homeowner in Aberdeen City Centre had a spreading ceiling stain and assumed the whole slate roof was done. Our inspection found two cracked slates and a failed pipe boot, with water tracking along the underlayment to a rafter.
After
We replaced both slates, installed a new pipe boot, and water-tested the repair for 20 minutes. The attic moisture reading dropped to normal, and the ceiling stain stopped growing after the next storm.
Windstorm Took Out Six Slates
Before
A Ferryhill home lost six slates in a Grays Harbor windstorm. Water was dripping into the attic and the homeowner could see daylight through the roof deck from inside.
After
We tarped the same day, then replaced all six slates with matching pieces and resealed the step flashing. A hose test confirmed the repair was watertight, and the attic dried out within a week.
Chimney Leak on a 1920s Slate Roof
Before
A Rosemount homeowner had water running down the chimney into the attic every time it rained hard. The original step flashing had pulled away from the masonry and the counter-flashing was rusted through.
After
We rebuilt the step and counter-flashing, replaced four slates disturbed during the repair, and sealed the masonry joint. The attic stayed dry through the next two storm seasons.

What Aberdeen Homeowners Say
★★★★★
“We had a stain spreading on the ceiling for weeks. Their inspector found two cracked slates and a failed pipe boot, replaced both, and water-tested everything before leaving. The stain stopped growing after the next storm. Price came in right where the written quote said, no surprises.”

★★★★★
“Our 1920s slate roof had three slipped tiles after a windstorm. They matched the replacement slate so well I cannot pick out the repair from the ground. Took about four hours, and they magnet-swept the yard for nails before they left.”
DR
Dave R.Homeowner, Ferryhill
✓ Verified★★★★★
“I called about a leak near the chimney and expected a full re-roof quote. Instead they showed me photos of the failed flashing, fixed that and four slates, and charged a fraction of what I feared. The attic has stayed dry through two storm seasons now.”
PS
Priya S.Homeowner, Rosemount
✓ VerifiedMost single-slate repairs in Aberdeen run $350 to $900 in 2026, and larger sections with new underlayment and flashing run $1,200 to $3,500. Pitch, roof height, and how many slates have failed drive the price. We give you a written scope and price before any work starts.
You lift the courses above the failed slate, cut the slate free, inspect the underlayment and flashing, set a matching replacement, and re-nail the course above it. It is a two-person job on a pitched roof, and we water-test the repair for 15 to 20 minutes before we call it done.
We do. Aberdeen Roof Leak Repair Pros handles slate leak repair across Aberdeen and Grays Harbor County, including Aberdeen City Centre, Torry, Ferryhill, and Rosemount. Call +13608991171 and we will schedule an inspection, often the same day.
Yes. In most cases we replace only the failed slates and the underlayment directly beneath them. A full tear-off is only needed when the slate field is failing across large sections or the decking is rotted, which we confirm with a moisture meter and infrared scan.
