The sequence of work

From delivery day to final walkthrough: what happens, in order

Delivery. Shingles, underlayment, flashing, and vents arrive before or at the start of the work. Bundles may be set on the roof by boom truck or staged on the driveway. Ask where the materials and the debris container will sit, because that decides which parking spots and garage doors you can use.

Protection and tear-off. Before anything is pulled up, landscaping, siding, windows, and the driveway are protected. The old roofing is then stripped down to the deck and hauled away as the work progresses. This is the loudest and messiest stage, and the one most worth planning your day around.

Decking review. Once the deck is exposed, it can be judged properly for the first time. Soft, delaminated, or rotted sheathing is photographed and reviewed with you before it is replaced, at the per-sheet price written in your estimate. Your part is simple but important: be reachable, so a decision does not hold up an open roof.

Installation, cleanup, and handoff. The new system is built back up — drip edge, underlayment and membranes, flashing, vents, and shingles — then the property is cleaned and checked for nails and scrap. The project ends with a review of the finished roof and the documents that apply to it. Asking about each of these stages before you sign makes it easier to compare contractors who describe their process very differently.

Sequence questions to ask before scheduling

Where will materials and the debris container be placed, and for which stage?
Will shingles be loaded onto the roof by boom truck or carried up?
How are landscaping, windows, and siding protected before tear-off?
How will you reach me when damaged decking is found, and what do you need from me?
What is the plan if weather changes while part of the roof is open?
What does cleanup include, and when is the nail sweep done?
What will I receive at the end — photos, warranty paperwork, product information?

Repair or replace

Is it time for a full replacement sequence?

A complete tear-off and rebuild is a bigger undertaking than a repair visit. It makes sense when the roof as a whole has reached that point, not just one part of it.

Often still a repair

One leak with a clear source, such as a cracked pipe boot or a lifted shingle, on a roof that is otherwise sound
Storm damage limited to a small area that can be matched and sealed
Ventilation or flashing problems at one location that can be corrected without disturbing the whole roof

Points toward replacement

Wear is spread across the roof — curling, cracking, or heavy granule loss — rather than in one spot
Repairs keep coming back in new places, so each visit is chasing a roof that is wearing out
An inspection finds soft decking or attic moisture in several areas, which a full sequence can address at once

Moss, stains, or a roof’s age alone don’t settle the question, and remaining life can’t be promised from a photo. An on-site roof inspection is the way to know. See also roof repair vs. replacement.

Scope

What a Wilsonville roof replacement scope should spell out

Because the sequence has distinct stages, a good written scope reads almost like a schedule of tasks: what is removed, what is reviewed, what is installed, and what is cleaned up. It should name the shingle line and color, underlayment and membrane locations, flashing replacements, ventilation changes, and how decking is priced and approved. That level of detail is what lets you hold the work to what you agreed.

Permits: requirements depend on the city or county with authority over the property — which isn’t always the city in the mailing address — and on the scope, such as whether sheathing or framing is replaced. Ask whether your project needs a permit and who will obtain it before work is scheduled.

Items your written scope should cover

Material delivery and staging location
Property protection before tear-off
Removal of all existing layers, with disposal
Decking review with photos and a per-sheet price
Underlayment, membranes, and drip edge
New flashing and pipe boots at every penetration
Ventilation plan for intake and exhaust
Cleanup, nail sweep, and final review

Cost factors

How the work sequence shows up in Wilsonville pricing

Each stage carries cost. Delivery and debris hauling depend on access and how much old roofing there is — two layers weigh and cost more to remove than one. Tear-off and installation time rise with pitch, the number of roof planes, and how many valleys, chimneys, skylights, and vents have to be worked around. The roof’s actual area, rather than the home’s living space, drives the material quantity.

The decking stage is where budgets most often move, because nobody can see the sheathing until the old roof is off. Estimates that state a per-sheet price for replacement, and say how you will approve it, make that stage predictable. An estimate that is silent about decking is not cheaper; it simply leaves the question for later.

More detail: what affects roof replacement cost and what a roofing estimate should include.

Compare Wilsonville estimates stage by stage

Is tear-off of every existing layer included?
Is disposal included, or charged separately?
Is the decking price per sheet, with an approval step?
Are flashing and pipe boots new, or reused?
Is the ventilation plan described, not just “vents”?
What does cleanup cover?

Process

How a Big Bear roof replacement runs

On-site estimate
A roofing specialist walks the roof, checks shingles, flashing, and ventilation, takes photos, gathers measurements, and emails you a detailed estimate.
Review and sign
You go over the written scope and options. When you are ready, you accept the estimate online with an e-signature and we schedule the installation date.
Tear-off and installation
The crew protects the property, removes the old roof, reviews the decking with you where repairs are needed, and installs the new roof system.
Cleanup and follow-up
Debris is hauled away, the property is checked for nails and scrap, and you receive follow-up messages and photo documentation of the work.

Preparing for each stage at your Wilsonville home

A short checklist before the start date makes the sequence go smoothly.

Move vehicles out of the garage if the driveway will hold materials or the container
Take down fragile wall décor on walls under the roof; tear-off can cause vibration
Cover belongings in the attic or garage where dust can fall through
Plan for pets and children to be away from the work areas during tear-off
Keep your phone handy on tear-off day in case decking needs your approval
Let neighbors know about deliveries and parking

The roof as a system

What goes into a complete new roof

Big Bear focuses on steep-slope asphalt shingle roofs, including architectural shingles and designer lines such as GAF Grand Sequoia. We don’t install flat or low-slope roofing. Exact components depend on your roof’s design, applicable code, and the manufacturer’s instructions.

Decking

The plywood, OSB, or board sheathing the roof is fastened to. It is checked once the old roof is off.

Underlayment and membranes

A water-resistant layer over the deck, with self-adhering membrane at vulnerable areas where specified.

Flashing

Metal at walls, chimneys, valleys, and skylights that turns water back onto the roof surface.

Roof edges

Drip edge at eaves and rakes, and starter courses that seal the first row of shingles.

Penetrations

Pipe boots, vents, and other openings, each sealed to suit the new roof.

Shingles

Architectural or designer asphalt shingles, installed to the manufacturer’s instructions for your roof’s pitch.

Ventilation

Intake and exhaust that suit the attic. What a given roof needs depends on its design, code, and the manufacturer.

FAQ

Roof replacement questions from Wilsonville, OR homeowners

What happens between material delivery and the final inspection?

In order: materials are delivered and staged, the property is protected, the old roof is removed down to the deck, the decking is reviewed and any damaged sheets are shown to you before replacement, the new roof system is installed, and the site is cleaned and checked for nails. The finished roof is then reviewed with you, along with the warranty and care documents that apply.

What happens if it rains in the middle of the work?

Tear-offs are planned around a reliable dry window, and the amount of roof opened at one time is limited so it can be covered if conditions change. Exposed areas are protected until the work can continue. Ask any contractor how they handle a forecast change before you sign.

Do I need to be home during the roof replacement?

Not the whole time, but it helps to be reachable, especially on tear-off day, in case damaged decking is found and needs your approval. You may also want to be home at the start to confirm where materials go, and at the end for the final walkthrough.

How do I book the on-site estimate?

You can call, send the form on this page, or book an in-person estimate online. A roofing specialist walks the roof, checks the shingles, flashing, and ventilation, takes photos and measurements, and emails you a detailed estimate. When you are ready, you can accept it online with an e-signature.

Does a Wilsonville roof replacement need a permit?

It depends on the authority for your property address and on the scope, such as whether structural sheathing will be replaced. Parts of Wilsonville sit in different counties, so confirm the right office. Ask whether a permit is needed and who will obtain it before the project is scheduled.
