Siding Replacement in Salem, Oregon: Steps, Permits, Costs

Siding replacement means stripping the old siding and trim down to the sheathing, repairing whatever has rotted underneath, rebuilding the wall’s weather layers, and installing new siding. In Salem, replacing the siding on its own does not need a building permit unless the wall must be fire-resistance rated, but repairing or replacing the sheathing does. Describe your house and we will follow up about a replacement quote.

When is it time to replace siding instead of repairing it?

Replacement is usually worth pricing when the same failure shows up on several walls, when rot has reached the sheathing in more than one place, or when the siding is a product nobody makes anymore. Swollen lower edges on hardboard or OSB lap siding and T1-11 panels peeling apart along the bottom are the textbook cases, because every board on the house is the same failing product. If the damage is confined to one wall, siding repair sets out, finding by finding, where a repair still makes sense. If a storm did the damage, read storm damage and insurance claims in Oregon before anything is torn off.

Siding replacement, step by step

A full re-side runs in roughly this order. Each step has a rule or a maker’s instruction behind it, which makes the list a useful checklist to hold a quote against. If a bid proposes leaving the old boards on instead, putting new siding over old siding covers what the makers and Oregon’s code allow.

Step	What happens	The rule behind it
1. Inspection	Every wall is probed for soft wood and checked for moisture. A house built before 1978 is flagged for lead-safe work.	Oregon’s lead renovation rules: 20 square feet or more of painted exterior on a pre-1978 home
2. Quote and contract	Material, removal, how rotted sheathing will be priced, barrier, drainage method, flashing, trim, paint and permits, in writing.	ORS 701.305: a written contract, with the contractor’s CCB number, for residential work above 2,000 dollars
3. Permit check	Siding alone is exempt. Sheathing repair, structural T1-11, and walls that must be fire-resistance rated are not.	Oregon Residential Specialty Code R105.2 and Table R302.1; City of Salem permit guidance
4. Lead-safe setup	Containment goes up before painted siding is disturbed.	CCB lead-based paint renovation license
5. Tear-off	Old siding and trim come off down to the sheathing.	HomeGuide notes removal is often left out of first estimates
6. Sheathing repair	Rotted sheathing is replaced. Under a permit, it stays exposed until the city inspects it.	City of Salem permit guidance; code sections R109.1 and R109.4
7. Water-resistive barrier	One continuous layer over every exterior wall. Felt is lapped 2 inches at horizontal seams and 6 inches at joints.	R703.2
8. Flashing	At windows and doors, above projecting trim, where decks attach, and a kick-out at every wall and roof intersection.	R703.4
9. Drainage space	A gap of 1/8 inch or more behind the siding, formed by furring, a drainage mat or drainage board, unless an exception applies.	R703.1.1
10. New siding	Installed to the maker’s instructions, keeping the gaps it sets above soil, roofs and decks.	R703.3 and the section for the material; the maker’s installation instructions
11. Caulk and paint	Joints treated as the maker specifies; primed boards painted within each product’s limits.	Maker’s instructions; paint temperature and dew-point limits
12. Final checks	A permitted job gets its remaining city inspections, and the finished walls are walked with the owner.	R109.4: work does not go past an inspection point until it is approved

Code sections are from the 2023 Oregon Residential Specialty Code, checked in September 2026. The Building Codes Division’s 2026 edition took effect on October 1, 2026, with a six-month phase-in during which either edition may be used before it becomes mandatory on April 1, 2027, so ask your contractor which one the job is built to. Steps 7 to 9 are set out layer by layer, with the six exceptions to the drainage gap, in house wrap and rainscreen rules in Oregon.

Permits for a full re-side in Salem

Oregon’s residential code exempts “replacement or repair of siding not required to be fire-resistance rated” from a building permit (section R105.2), and the City of Salem applies the same line; Salem’s siding permit rules covers both of the city’s permit pages. Four things move a re-side across it:

• Sheathing. Salem requires a building permit to repair or replace the sheathing behind the siding, which is why the scope of a job can change once the old boards are off.
• Structural T1-11. Where T1-11 panels are nailed straight to the studs, they are the sheathing, and replacing them needs a permit.
• Rot repair. The city’s permit page lists dry rot repair among work that always needs a permit. If rot turns up during the tear-off, ask the city how the repair is classed before the wall is closed.
• Walls near a property line. The code’s Table R302.1 requires a one-hour fire-resistance rating on an exterior wall less than 3 feet from a property line. Siding on that wall is not covered by the exemption.

Under a permit, the work “shall remain accessible and exposed for inspection purposes until approved” (section R109.1), so the barrier and siding go on only after the sheathing passes. On a historic property, a change of siding type, style or material also needs historic design review before work starts. Keizer takes permit applications at the city with Marion County forms, and Silverton’s building department lists siding on a wall three feet or more from a property line among its no-permit jobs; see the Keizer and Silverton pages.

A re-side, before and after

Which material goes back on?

The four common replacements around Salem are fiber cement, vinyl, engineered wood such as LP SmartSide, and cedar. The table further down this page sets them side by side on what the code asks of each, how each is fastened and finished, and whether this site can publish a cost for it; engineered wood, for one, goes up blind nailed with hot-dip galvanized nails and, like primed fiber cement, has to be painted within 180 days. How each copes with Salem’s rain, heat and ice-storm limbs is covered in the best siding for Salem’s climate. Engineered wood lap siding is a different product line from the LP Inner-Seal OSB siding of the late 1980s and early 1990s.

On a Salem historic property, switching from one siding material to another needs historic design review, so check before choosing.

What does each material cost to put back on?

This site publishes whole-job figures for two of the four materials and none for the other two. Each published figure is an average cost of replacing 1,250 square feet of siding, trim included.

• Fiber cement: $22,555 as the Pacific-region average in the Remodeling 2025 Cost vs. Value Report (www.costvsvalue.com), and $17,948 in the Remodeling 2024 Cost vs. Value Report (www.costvsvalue.com) for Albany, Oregon, about 25 miles south of Salem.
• Vinyl: $18,507 as the 2025 Pacific-region average, and $19,172 in the 2024 figures for Albany.
• Engineered wood: no figure. No dependable published source was found, so none is given.
• Cedar: no figure, for the same reason.

The regional averages put vinyl below fiber cement, and Albany’s put it above, so the published numbers do not settle which material is cheaper for a Salem house. Removing the old siding can be a separate line on a quote: the report’s project description does not itemize it, and HomeGuide notes it is often left out of first estimates. HomeGuide’s national range for removal and disposal is $70 to $200 per square (100 sq ft of wall).

Trim, soffits and fascia

Corner boards, window and door trim, and the drip caps above openings are part of how the wall sheds water, so they are normally replaced with the siding and flashed at the same time. Soffits and fascia sit under the roof edge and vary more from job to job: some are sound and stay, some are rotted and get replaced. Ask for each as a separate line on the quote.

They rot for the same reason siding does. The Forest Products Laboratory’s Wood Handbook calls roof edges, and the points where roofs meet walls, critical places for decay, and recommends gutters and downspouts kept free of debris. A National Park Service preservation brief shows a cracked gutter that let water rot the fascia boards behind it. So the fascia behind a gutter that overflows or leaks is the first place to probe, followed by the soffit boards beside it. A contractor checking the eaves pushes on both for soft wood, looks at where the gutter spills, and checks that the soffit vents are open. Gutters and roofing are separate trades, so a siding quote may replace the fascia board and leave the gutter to someone else.

Soffit vents are part of the attic’s ventilation, not decoration. The 2023 Oregon Residential Specialty Code requires enclosed attics to have cross ventilation through openings protected against rain and snow (section R806.1), and says that where eave or cornice vents are installed, “blocking, bridging and insulation shall not block the free flow of air” (R806.3). Ask how a new soffit will keep at least the vent area the old one had. In fiber cement, James Hardie makes soffit panels both vented and non-vented, and its installation guide rates the vented panels at 5 square inches of net free ventilation per lineal foot; it pairs them with its fascia trim boards, which it describes as decorative, non-load-bearing trim. Allura’s fiber cement soffit also comes vented or non-vented. When the rot is confined to the roof edge, soffit and fascia repair in Salem walks through checking the eaves, the materials and which trade fixes which part.

Replacing siding on a house built before 1978

Pre-1978 paint may contain lead, and tearing off painted siding disturbs a lot of it. Oregon runs its lead renovation rules through the Construction Contractors Board and the Oregon Health Authority. A contractor who disturbs 20 square feet or more of painted exterior on a pre-1978 home needs a CCB lead-based paint renovation license and must follow lead-safe work practices, including containment and cleanup. The median home in Silverton was built in 1978 and in Salem in 1980 (Census ACS 2020-2024), so this comes up often.

Lead is not the only old-house question. Oregon’s Department of Environmental Quality names cement siding among materials that can contain asbestos, and requires an asbestos survey by an accredited inspector before most renovation of a home built before 2004. Read asbestos siding rules in Oregon before a tear-off on an older house.

What should a siding replacement contract include in Oregon?

Under ORS 701.305 and the CCB’s contract rules, residential work priced above 2,000 dollars needs a written contract showing the contractor’s name, address, phone number and CCB license number, and the state’s consumer notices must be delivered on or before the day it is signed. Before you sign, look the contractor up on the CCB license search, and check that the name on the license matches the name on the contract. On a house built before 1978, also ask for the CCB lead-based paint renovation license, since a tear-off disturbs far more than 20 square feet of painted siding. Then read what the quote includes: removal and disposal, how rotted sheathing will be priced, the barrier and drainage method, flashing, trim, paint and permits.
