Metal Siding Installation
Standing seam, corrugated, flush-lock — for homes that need fire resistance, zero maintenance, and a modern line. Rainwood Construction handles metal siding installation from substrate prep through trim.

Why Metal Siding Is Gaining Ground
Metal used to mean agricultural buildings and warehouses. Not anymore. Standing seam and corrugated profiles show up on residential remodels all over the PNW — mixed with cedar, fiber cement, or running full-envelope on contemporary builds.
The appeal is straightforward. Metal doesn’t rot, burn, or absorb moisture. Coated steel panels carry a 25-year finish warranty and a realistic lifespan north of 40 years. PVDF coatings like Kynar 500 resist fading and chalking better than any painted wood or fiber cement finish.
But metal siding installation details matter more than with forgiving materials like vinyl. Thermal expansion on a 16-foot steel panel is ~1/8” over a 100°F swing — ignore that and panels buckle. Dissimilar metal contact triggers galvanic corrosion. Every penetration needs purpose-built flashing. Metal is unforgiving. Do it right or it shows.
Metal Siding Installation Cost
Material ranges widely. Corrugated steel (26-gauge Galvalume) runs $2–4 per square foot. Standing seam in 24-gauge PVDF finish hits $5–9. Aluminum composite for flush looks runs $8–15.
Installed with furring, WRB, flashing, and trim — expect $7–14 per square foot for steel, $10–18 for aluminum composite. A 1,500 sq ft home in corrugated lands $12,000–20,000. Standing seam full envelope on a two-story pushes $25,000–40,000. Rainwood Construction quotes after on-site inspection — line-item scope, not a lump sum.
OUR SIDING SERVICES
What Rainwood Construction covers for metal siding installation projects.
Vertical Metal Siding Installation
Standing seam and corrugated panels running vertically — the most common residential metal profile. Any vertical metal siding installation guide will spec hat channel or Z-furring over the WRB for drainage and a flat plane. We screw through furring, not through the barrier. Standing seam uses concealed clips; corrugated uses exposed fasteners with EPDM washers.
Horizontal Metal Siding Installation
Flush-lock, lap, or corrugated running horizontally. Horizontal metal siding installation needs vertical furring and careful water management — horizontal laps catch water differently than vertical runs. We back-flash every joint and use a vented base detail so moisture drains, not pools.
Corrugated Metal Siding Installation
Corrugated is the workhorse — 7/8” wave profile in 26- or 24-gauge coated steel. Corrugated metal siding installation details that matter: overlap one full corrugation, fasteners in the flat (not the crown) on walls, foam closure strips at top and bottom against insects and wind-driven rain. Most mistakes come from roofers applying roof fastening patterns to walls.
Metal Siding Corner Trim Installation
Inside corners, outside corners, J-channel, head/sill trim, transition flashings. Metal siding corner trim installation is brake-formed on site from matching coil stock — not generic off-the-shelf pieces. Every outside corner gets a hemmed edge for rigidity and a clean shadow line.
Metal Siding Repair
Dent repair, panel replacement, fastener re-seating, touch-up on scratched PVDF. Metal panels are individual units — a damaged section swaps without stripping the whole wall. Color matching is the challenge; we order from the same manufacturer and coil lot when possible.
Rainwood also offers interior renovations. Contact us to discuss your project.

COMMON PROBLEMS WE FIX
Metal siding failures — usually fastening or flashing mistakes.
Why Choose Rainwood?
Metal siding installation guide specs exist for a reason — thermal movement, galvanic isolation, drainage. Skip any and a 40-year material fails in 5. Rainwood Construction treats every metal job as an engineered assembly.
- Thermal expansion gaps calculated per panel length and local temperature range
- Galvanically compatible fasteners for every metal-to-metal connection
- Hat channel or Z-furring rain screen on every install — no direct-to-sheathing attachment
- Brake-formed trim from matching coil stock, hemmed edges, site-fit to each condition

We had an excellent experience with them on our sunroom project. The quality of the work was outstanding, they were easy to work with, and they clearly explained each step, the schedule, and key decisions (with various options to help us understand cost) along the way. Communication was solid from start to finish, and the final result looks great. Highly recommend, they are my new go to recommendation when friends ask.
Rainwood construction completed 2 projects in my home recently. The first, which was to add a bar in my family room, which when completed fit so well that it looked like it always belonged there. It came out exactly how we wanted it and we love it. The second project was to completely remodel and modernize my 1955 original kitchen. The kitchen turned out fantastic! It’s light and bright with clean lines exactly how we had envisioned it. The team was polite, competent, hard working and always cleaned up after themselves at the end of the day. They always made sure to ask how I wanted things done when there were options, making suggestions where needed and made sure I was happy with the completion of items along the way. I was very pleased with the quality of the work, plan to use them again in the future and have already recommended them!
Excellent work done ✅ I’m really impressed and looking forward working further. Recommend 👍
Anatoliy and his company, is great person to have a business with!!!
We just remodelled the entire main floor of our house; the scope included changing floors, installing new cabinets including a drop ceiling, added a custom entertainment wall, and fully upgraded the powder room, among other work such as electrical upgrades including an EV plug. We are overall very happy with the work that the team has done, satisfied with the cost, and definitely recommend them to others.
Toli did great work renovating our home and upstairs bathroom. It was a great change.

On-Site Assessment
Wall flatness check, substrate evaluation, moisture readings. Metal is unforgiving on wavy walls — we identify where furring or shimming is needed.
Clear Scope & Schedule
Panel manufacturer, gauge, finish, trim details, furring spec, labor breakdown. Most metal re-sides run 6–12 working days depending on profile complexity and mixed-material transitions.
Installation
Tear-off (if needed), WRB, furring, flashing, panels, trim, sealant, cleanup. Walkthrough before closeout.

FAQ
Coated steel with PVDF finish — 40–50 years realistically. The coating does the heavy lifting. Kynar 500 resists fading and chalking far longer than polyester coatings. Uncoated steel weathers to matte grey and lasts structurally just as long but won’t hold consistent color.
Zinc-aluminum coated steel resists corrosion well — the alloy layer sacrificially protects the base steel. Cut edges are the vulnerability. Every field cut exposes raw steel, so we seal them with manufacturer touch-up and keep them from standing water. Aluminum panels don’t rust at all but cost more.
Excellent here. Metal sheds rain instantly, absorbs no moisture, handles temperature swings without rot risk. In coastal areas, use coated steel or aluminum — not bare steel. Main PNW concern is moss in corrugation valleys on shaded walls. Periodic wash-down handles it.
That’s how most residential metal projects work. Corrugated or standing seam on upper stories, cedar or fiber cement below, metal accents on entries. Transitions need purpose-built flashing — Z-bar, drip edge, sealant at every material change. Looks great but doubles the detail work.
