Shingle selection

Choosing a shingle is choosing a system, not a color

Most replacement roofs on homes around Clackamas are steep-slope asphalt shingle roofs, and most homeowners start with color. That is a fine place to start, but the more consequential decisions sit underneath it: which product line, which components are paired with it, and whether the installation meets the manufacturer’s instructions. Those three things together decide how the roof performs and which warranty applies.

Architectural (dimensional) shingles, such as GAF Timberline HDZ or Owens Corning Duration, are the common choice. They are layered for depth and suit most pitched roofs. Designer shingles, such as GAF Grand Sequoia, are thicker and cut to resemble wood shakes, which can suit a home where the roof is a large part of the view or an old shake roof is being replaced. The tradeoff is usually price and weight against appearance. The product also has to be approved for your roof’s pitch.

Compatibility is where proposals quietly differ. Manufacturers make starter strips, hip and ridge caps, underlayments, and ventilation products designed to work with their shingles, and some offer enhanced system warranties only when qualifying components are installed together and the roof is registered. A proposal that pairs one brand’s shingle with generic accessories can still be a good roof, but it may not qualify for the same coverage. You should know which you are buying.

Finally, read the warranty as two separate promises. The manufacturer’s limited warranty covers the product under its terms. The contractor’s workmanship coverage addresses the installation. Ask for both in writing, ask what registration requires, and ask what could void coverage, such as installation outside the instructions.

Questions to settle before approving your material package

Which exact product line and color is in the estimate — not just “architectural shingle”?
Is the product approved for every pitch on my roof, including low porch sections?
Which starter, hip and ridge, and underlayment products are paired with it?
Does that combination qualify for a manufacturer system warranty, and is registration included?
What does the workmanship warranty cover, and where is its term written?
Can I see physical samples, not only screen images, before ordering?

Repair or replace

New shingles on a repair, or a new roof?

Matching an older shingle for a repair is not always possible, and a mismatch is one reason homeowners begin thinking about replacement. Appearance alone is not the deciding factor, though.

Often still a repair

A small area of damage where a close color match is available and the surrounding shingles are still flexible
A failed accessory — a ridge cap, a vent, a pipe boot — that can be replaced on its own
A roof that is mid-life, where a visible patch is acceptable to you

Points toward replacement

The shingle line has been discontinued and patches stand out across several slopes
Shingles are brittle, cupped, or bare of granules over large areas, so repairs crack surrounding pieces
You want a different product class, such as moving from three-tab to architectural shingles

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 Clackamas roof replacement scope should state about materials

A material-focused scope names every product, not only the shingle: starter, underlayment, membrane locations, drip edge, flashing, pipe boots, vents, and hip and ridge caps. It should also cover the work that makes those products perform — tear-off to the deck, decking review once exposed (with damaged sheets photographed and reviewed with you before replacement, at the per-sheet price in the estimate), and ventilation suited to the attic.

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

Shingle manufacturer, product line, and color
Matching starter strip and hip and ridge caps
Underlayment type and membrane locations
Drip edge, flashing, and pipe boots listed as new
Ventilation products and locations
Tear-off of all layers, with disposal
Decking review and per-sheet price
Warranty registration, if a system warranty applies

Cost factors

How material choice affects Clackamas roof replacement cost

The product line is one of the few cost factors you choose directly. Designer shingles cost more than architectural shingles and can take longer to install. Matching system accessories add to the material list. Beyond that, the measured roof area (not the home’s floor area), pitch, number of valleys and penetrations, flashing, layers to remove, disposal, and access all shape the price in the same way regardless of the shingle.

Two estimates using the “same” shingle may still differ because one includes matched accessories and registration and the other does not. Decking is the hidden variable on any roof; it cannot be fully seen until tear-off, which is why a stated per-sheet price is more useful than a single total that assumes the deck is perfect.

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

Compare material packages fairly

Is the same shingle line and color quoted in each estimate?
Are the accessories named, or listed only as “materials”?
Which manufacturer warranty does each package qualify for?
Is warranty registration included?
How is decking replacement priced?
What workmanship coverage is offered, in writing?

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.

Choosing materials for your Clackamas home

A little homework makes the material decision easier and faster.

Look at samples outdoors, in daylight, next to your siding and trim
Drive past homes with the colors you are considering
If an HOA applies, confirm its approved colors and products before ordering
Ask for the manufacturer’s warranty documents for the product being quoted
Note any low-slope porch or patio roofs so product suitability can be checked
Decide whether skylights or vents should be replaced to match the new roof

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 Clackamas, OR homeowners

How should I compare architectural shingles and their warranty terms?

Compare the exact product line, the accessories paired with it, and the written warranty terms side by side. Manufacturer warranties vary by product, by whether qualifying components are installed together, and by registration. Ask what the workmanship warranty covers separately. Our warranty page explains the difference between the two kinds of coverage.

What is the difference between architectural and designer shingles?

Architectural shingles are layered to create depth and are the most common choice for pitched roofs. Designer shingles, such as GAF Grand Sequoia, are thicker and shaped to look like wood shakes. They cost more and suit homes where appearance is a priority. See our asphalt shingle roofing page for color lines.

Do the starter strips and ridge caps have to be the same brand?

Not always, but some manufacturer system warranties require qualifying components from the same manufacturer. If a particular warranty matters to you, ask whether the quoted accessories qualify, and whether the roof will be registered.

Is my Clackamas address handled by the county or a city?

Many addresses labeled Clackamas are in unincorporated Clackamas County, while others fall within nearby city limits. When a permit is required, the authority for your exact address decides where it comes from. Confirm it before the project is scheduled.

Can I see shingle samples before I decide?

Yes, and you should. Screen colors are only a rough guide. Physical samples viewed outdoors, at different times of day, give a much better sense of how a color will look on your roof.
