Full tear-off and replacement
The whole covering is removed to the deck and a new system is laid. The usual choice when the deck is sound and the covering is at the end of its life.

Full Replacement
Full Roof Replacement: what it covers
Quick answer
A full replacement strips the old covering, checks and repairs the decking, lays new underlayment and fits a new covering with new flashing. The quote is set on site, and the contractor licence and any permit are confirmed before work starts.
A replacement is the largest job a roof will get, and it should follow a full inspection rather than a single leak. A roof with a sound deck, a covering near the end of its life and repairs that keep returning is a candidate. A roof with one damaged area usually is not.
In this area two things often decide the scope. The first is moss history: a roof that has carried a thick mat for years may have lifted tabs and soft decking under the covering. The second is the windstorm record, since a roof that has been through a wind event may have damage that a repair cannot reach.
This page sets out how a replacement is scoped, what it includes and what it does not. The price is not on this page, because it cannot be read off a roof from a distance. The roofer sets it on site, and the written quote breaks it into lines.

Warning signs
Signs you need full roof replacement
Replacement involves tear-off, fall exposure and heavy material. Keep children and pets clear of the yard during tear-off, and ask the roofer to show the fall-protection set-up before work starts.
- Repairs that keep returning at different points on the same roof
- Granules worn away in large patches, leaving the mat exposed
- A deck that gives under foot, or a ceiling that sags across a wide area
- Shingles that crack when lifted, which means the sealant and the mat have lost their flexibility
- Heavy moss over most of a slope, with lifted tabs underneath
- Damage from a named windstorm across most of one or more slopes
Our process
How our full roof replacement visit works
Inspect the roof and the attic
The roofer checks the whole roof, the attic and the decking, and records the state of the covering, the flashing, the drainage and the moss before any quote is written.
Confirm the licence and the permit
The roofer's Oregon CCB licence is checked on the Board's site, and the permit question is answered by the local building office for the address before the start date is set.
Write the scope line by line
The scope lists the tear-off, the decking, the underlayment, the covering, the flashing and the vents as separate lines, so each can be checked against the work.
Strip the old roof and repair the deck
The old covering is removed to the deck, which is checked for rot and damage. Damaged sheets are replaced and added to the job as a separate line, priced per sheet.
Lay the underlayment, covering and flashing
The underlayment goes on first, then the covering and the flashing, with each stage checked before the next. The job ends with a clean-up and a walk-through with you.
Cost
How much does full roof replacement cost in Hillsboro?
No dollar figure appears on this page. A price cannot be read off a roof from a distance, so the number is set after the roofer has been on it. Ask for a written quote that itemises what you are buying.
| Job | Typical range | What it includes |
|---|---|---|
| Roof area and number of planes | Priced by the roofer on site | A simple gable is cheaper to cover than a roof with many changes of plane, because each change adds cuts and flashing. |
| Tear-off and layers to remove | Confirmed once the roofer sees the roof | A second or third layer adds labour and disposal, and the quote should state it. |
| Decking repair | Quoted per sheet, if needed | Damaged sheets found at tear-off are replaced and added to the job at the stated unit price. |
| Flashing and penetrations | Itemised in the quote | Chimneys, walls and vents take hand work, and that is where a cheap part costs more later. |
| Permit and any required review | Ask who files and who pays | Confirm the process with the local building office before the start date is set. |
The roofer sets the price, and it is confirmed in writing on site before any work starts. A quote that leaves these lines out is incomplete.
Does a re-roof here need a permit?
The FACTS sheet does not identify the City of Hillsboro building division for this site, so the roofer must confirm which office applies and what it requires.
The sources for this site did not identify the City of Hillsboro building division, and this page does not state a permit rule or a fee. A roofer who works in the city will know the usual steps, but the answer should come from the office for the address.
Ask who files the permit, who pays for it and whether an inspection follows. Get the answer in writing with the quote, before any deposit is paid.
- Ask which building office covers the address
- Ask who files and who pays
- Ask for the inspection steps in writing
What about the contractor licence?
Oregon's Construction Contractors Board licenses residential and commercial contractors. The roofing class must be verified on the CCB site, and this page does not state it.
The FACTS sheet records that the Oregon Construction Contractors Board licenses residential and commercial contractors, and that the roofing-specific class should be verified on the CCB site before it is quoted. Sources conflict on the categories, so none is stated here.
Check the licence number on the CCB site before the deposit is paid, and keep the dated result with the contract.
- Verify the roofing class on the CCB site
- Check the number before the deposit is paid
- Keep the dated result with the contract
Is the whole roof always replaced?
Not always. A sound deck and a serviceable covering can sometimes be partly replaced, but the moss history and the deck condition decide it.
A partial replacement over one slope is reasonable when the rest of the roof is sound. Overlays can hide problems that a full tear-off would find, so the roofer says what is covered and what is not. A roof that has carried moss for years is checked at the deck before any overlay is discussed.
The new section is matched and sealed to the old, and that junction is checked as part of the scope.
- Check the deck on every slope first
- Name the areas that stay in place
- Check the junction of new and old work
What should the contract say?
The scope, the material, the warranty terms, the payment schedule and the clean-up. Nothing should rest on a verbal promise.
Ask for the material name and manufacturer, the underlayment, the flashing, the warranty terms from the manufacturer and the installer, and the payment schedule. Ask how hidden decking damage is priced and approved, and what happens if the deck is found soft.
Keep the licence number, the permit answer and the inspection steps with the contract, so the file shows the checks were made.
- Material, manufacturer and warranty in writing
- How hidden decking damage is priced and approved
- Licence, permit and inspection kept with the contract
Options
Types and options for full roof replacement
Replacement after moss damage
A replacement where moss has held water long enough to soften the deck and lift tabs across most of the roof.
Partial replacement
One damaged slope replaced where the rest of the roof is sound. The new section is matched and sealed to the old.

Why full roof replacement is different in Portland metro
FACTS.md states that snow and ice are not a main driver for the metro and that no snow load is stated, so this page does not give a load figure.
The moss history of a roof is part of the scope. A roofer records the moss, the lifted tabs under it and the deck condition before any quote is written.
Replacements in Forest Grove, Banks and the Coast Range foothills follow the same scope, and the travel is shown on the quote.

FAQ
Full Roof Replacement FAQs
How long does a full replacement take?
Most single-house jobs take a few days, depending on size, weather and any decking repair. The roofer gives a schedule when the quote is written.
Do I have to be home during the work?
Not always, but the roofer will want access to the house and yard, and to confirm where material is placed.
Should moss be removed before the new roof?
The tear-off removes the moss. The deck is checked for damage the moss caused.
What if the roofer finds soft decking?
Damaged sheets are replaced and the cost is a separate line that you approve before the work is done.
