Metal Roofing Quick Start Guide for Valley Outdoor Supply
This page is your fast path for planning a clean, durable metal roofing project in the Pacific Northwest. Use it to choose panel type, estimate coverage, understand overlap, and order the right fasteners and trim.
Roofing first, then accessories, then moisture control. Bring your measurements and we will help match panels, trim, and screws before pickup.
1) Start with measurements
Measure roof run, width, slope direction, and overhang. A quick hand sketch saves time and prevents ordering mistakes.
Go to measuring2) Choose panel profile
Pick corrugated or 36 inch rib based on look, span, and job type. Then choose panel length and finish.
Choose panels3) Match screws and trim
Fasteners, closure details, and trim pieces matter. This is where leaks and callbacks are usually prevented.
Match hardware4) Moisture control for CONEX and enclosed spaces
If you are covering a container or enclosed metal space, use the DRY-CON lane to address condensation and airflow.

- Questions about trim details
- Pickup timing or delivery request
- Any moisture concerns for enclosed spaces
📏 Measure your roof or build before ordering
Start with the roof plane, not the footprint. Panel quantities depend on the actual surface dimensions and overlap plan.
- Run: ridge to eave direction (or high side to low side on a lean-to)
- Width: side-to-side coverage across the roof
- Overhangs: eave and side overhang amounts
- Panel direction: make sure your panel orientation matches your framing plan
🧱 Choose the right panel type and gauge
Valley Outdoor Supply stocks metal roofing panels for practical outdoor builds in Pacific Northwest weather. The right choice depends on your project type, span, and finish goals.
Corrugated panels
- Traditional look for sheds, shops, farm structures, and fencing
- Common choice for mixed roofing and siding projects
- Works well with polycarbonate daylight panels in matching profiles
36 inch rib panels
- Fast coverage for larger roof areas
- Clean lines and efficient install
- Great when speed and square footage matter
📐 Coverage and overlap basics
The most common ordering mistake is forgetting overlap. Panel width is not the same as net installed coverage width.
Side overlap
Adjacent panels overlap at the side laps, reducing net coverage width.
End overlap
Multi-piece runs need overlap at horizontal joints, which affects total panel count and layout.
🔩 Screws, closures, and trim that match the job
Panels are only part of the system. Fastener type, washer quality, and trim details are where long-term performance is won or lost.
Fasteners
- Match screw type to wood framing or steel framing
- Use the correct washered roofing fasteners
- Plan quantity by panel count and framing layout
Trim and details
- Ridge and edge trim details
- Closure and sealing details as needed
- Match trim color and profile to panel system
☀️ Polycarbonate lane for daylight panels and greenhouse roofing
Polycarbonate panels are a strong option when you need daylighting, greenhouse coverage, or clear roof sections integrated with metal panel systems.
- Great for greenhouse roofs and outdoor covered spaces
- Can be used for daylight panel sections in compatible layouts
- Ask us about profile matching and fastener planning
💧 DRY-CON lane for CONEX moisture control and enclosed metal spaces
If you are working with a CONEX container, enclosed metal roof, or any structure with condensation issues, moisture control needs to be part of the plan from the beginning.
Common moisture problems
- Condensation drips from temperature swings
- Rust risk in enclosed spaces
- Stored tools and materials exposed to humidity
What to plan for
- Air movement and ventilation path
- Moisture-control product selection
- How your roof and enclosure system work together
