Records and coverage

Build the roof’s paper trail while the work is happening

A roof is mostly hidden once it is finished. Nobody will see the decking, the underlayment, the membrane in the valleys, or the step flashing behind the siding again until the next reroof. The documents from the project are the only lasting evidence of what is actually up there. If a question comes up later — a leak, a buyer’s inspection, a warranty claim — those records are what everyone will rely on.

The most useful set includes the signed scope (what was supposed to be done), any approved changes (such as decking replaced after tear-off), the exact shingle line and color, the accessory products used, and photos taken during the work. Big Bear documents projects with photos and notes of what was found and what was done, and damaged decking is photographed and reviewed with you before it is replaced. Ask for those photos to be part of your record, not just the before and after.

Warranty documents deserve special attention, because there are usually two kinds and they answer different questions. The manufacturer’s limited warranty covers the products under its terms and may depend on registration. The contractor’s workmanship warranty covers the installation, with its term and conditions written in the project agreement and warranty certificate. Keep both, and note whom to contact for each.

Records also protect coverage. Some warranties can be affected by later changes, such as another company cutting in a vent or mounting equipment through the roof. Keeping the original documents, and noting any later work on the roof, makes it easier to sort out who is responsible if something goes wrong.

Repair or replace

Repair or replace — and what your records can tell you

Past paperwork often helps answer the repair-or-replace question. Knowing when the roof was installed, with what, and what has been repaired since gives an inspector useful context.

Often still a repair

Records show the roof is relatively young, and the problem is a single damaged area or component
A leak traces to later work, such as a newly added vent, rather than the original roof
The roof is still under a workmanship or product warranty that may apply — check before hiring anyone else

Points toward replacement

Repair invoices show leaks returning in different places over several years
The roof has more than one layer or unknown history, and wear is widespread
An inspection finds soft decking in multiple areas, pointing to long-term water entry

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 well-documented St. Helens roof replacement scope includes

The scope should describe the full roof system — tear-off, decking review, underlayment, membranes, flashing, ventilation, and shingles — in enough detail to serve as a record afterward. It should also describe how changes are documented: what happens when damaged decking is found, how it is photographed and approved, and how the final list of work is delivered to you at the end.

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

Tear-off and disposal of all existing layers
Decking review, with photos and a per-sheet price for replacement
Named shingle line and color
Named underlayment, membrane, and accessory products
Flashing replacements listed by location
Ventilation plan described in writing
Workmanship warranty terms referenced in the agreement
Final documentation delivered at project close

Cost factors

How the scope and its records shape St. Helens roof replacement cost

Price follows the measured area of the roof — not the house’s living space — together with pitch, access, number of layers to remove, disposal, and the valleys, chimneys, skylights, and vents that need flashing. Material choice matters too, especially between architectural and designer shingles, and some manufacturer system warranties require specific matched accessories that change the material list.

Hidden decking is the variable most likely to change the final total, which is why it is priced per sheet and approved in writing as it is found. That approval becomes part of your record, so the final invoice can be traced back to what was actually discovered. A low estimate that leaves decking, flashing, or registration undefined may end up being the harder one to document.

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.

Before your St. Helens project starts

Gathering what you already have makes the estimate more accurate and your final record more complete.

Find any paperwork from the previous roof or past repairs
Note where and when leaks have happened
Set up a folder, paper or digital, for the new roof’s documents
Check your home insurance policy for anything it asks about roof age or materials
Clear the driveway and move items away from the house
Decide who in the household will approve changes during the work

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 St. Helens, OR homeowners

Which warranty documents and installation records should I keep?

Keep the signed scope, written approvals for any changes, the shingle line and accessory products used, photos taken during the work, the workmanship warranty certificate, and the manufacturer warranty information with any registration confirmation. Store them where you can find them years from now. Our warranty page explains how the two types of coverage differ.

What is the difference between a workmanship warranty and a manufacturer warranty?

A manufacturer’s limited warranty covers the roofing products under its terms, which can depend on the product line and registration. A workmanship warranty is the contractor’s coverage for the installation. Big Bear’s workmanship terms are written in the project agreement and warranty certificate.

How do I make a warranty request later?

If you have a concern with a roof Big Bear installed, use the request form on our warranty page. Describe the problem and share photos taken safely from the ground or indoors. Having your project documents handy speeds up the review.

Can later work on my roof affect the warranty?

It can. Penetrations or equipment added by others after the roof is installed may affect coverage for those areas. Keep records of any later work and check your warranty terms before allowing changes to the roof.
