Architectural metal roofing · Pacific Northwest
A roof drawn with the care of the house.
Ridgeline designs and installs standing-seam and other premium metal roofs as complete assemblies: panel, fastening, underlayment, ventilation and flashing, specified together and priced in the open.

01 Concealed-clip standing seam02 Matched flashing and gutterOur position
A metal roof is not a product you buy by the square foot. It is a precise assembly that has to shed water, move with the weather and look right for decades. We treat it like architecture, because it is.
The estimate
Three things that make a metal roof estimate different.
It starts with geometry, not price per square
Hips, valleys, dormers, chimneys and skylights are individual pieces of flashing. Two roofs with the same area can differ widely in labour. We measure and draw the roof before we quote it.
It prices the assembly, not just the panel
Clips, underlayment, ventilation, deck repair and trim usually decide whether a roof performs. We itemise them so you can compare like with like.
It plans for movement, snow and water
Metal expands, snow slides and rain finds the weakest detail. The scope says how each is handled, and where it is not included, in writing.

The process
Five steps, everything in writing.
- 01
First conversation
We start with the house, not the roof: what you want it to look and feel like.
- 02
Roof assessment
We measure and read the roof, including the deck beneath it.
- 03
Design and written scope
Profile, metal, finish and every flashing detail, drawn and itemised.
- 04
Fabrication and installation
Panels formed to length and installed on a protected, prepared deck.
- 05
Completion and handover
A final walk-through, clean site and the documents you need to look after it.
Materials
Four metals, honestly compared.
- Lower tier
Coated steel
The workhorse: strong, broad colour choice, sensible cost.
- Moderate tier
Aluminium
Light, corrosion-resistant, a natural choice near the coast.
- High tier
Zinc
A living finish that darkens and self-heals as it weathers.
- Highest tier
Copper
The classic: warm at first, green over time, or kept brown.
Concept projects

Is a metal roof loud in the rain?
Not when it is built as a system. Rain noise comes from the panel vibrating, and what controls that is the solid deck, the underlayment and the insulation beneath, not the metal itself. Over a solid deck with a good underlayment, a standing-seam roof is typically comparable to other roofing in heavy rain.
How does a metal roof cope with snow and heavy rain?
Smooth metal sheds both quickly, which is a strength in the Pacific Northwest. The seams run eave to ridge so water has an uninterrupted path to the gutter.
Doesn't metal expand and contract?
Yes. Every metal moves with temperature, and aluminium moves more than steel. A properly designed roof allows for that: panels are held by clips that allow them to slide, and fixed points are limited and placed deliberately.
How long will a metal roof last?
Metal roofs generally outlast most other residential roofing, and well-detailed zinc and copper roofs have a long track record. We will not put a single number on it, because the honest answer depends on the metal, the coating, the installation, your climate and how the roof is maintained.
