2026 equipment update. The current IronRidge residential range is the XR rail family — XR10, XR100 and XR1000 — with FlashFoot2 as the standard composition-shingle attachment, all carrying a 25-year warranty. Current specifications and how they map onto our roofs and our weather are below.
If you have been reading solar quotes side by side, you have probably seen the name IronRidge on more than one of them. It is the racking — the aluminum framework that actually holds your panels to your roof. It is also the part of a solar array almost nobody asks about, right up until a Gorge windstorm rolls through Washougal and they suddenly care a great deal.
Here is what IronRidge racking is, why it comes up so often on Pacific Northwest roofs, and what to actually look for when you are comparing quotes.
What is IronRidge?
IronRidge is a California-based manufacturer of solar mounting and racking systems, in business for roughly two decades. They make the rails, roof attachments, flashings and clamps that secure solar panels to a roof or a ground mount. They do not make solar panels or inverters — they make the structural system everything else sits on.
Their residential products are built from aluminum with stainless steel hardware, which matters in a wet climate. Rust is not a theoretical problem west of the Cascades.
Why does racking matter more in the Pacific Northwest?
Because our loads are unusual. A roof in Phoenix mostly needs racking that survives heat. A roof in Washougal, Camas or the Columbia River Gorge has to handle sustained wind, winter snow load at elevation, and constant moisture — sometimes all three in the same week.
Two things follow from that:
- Wind matters more than most homeowners expect. The Gorge is one of the windiest corridors in the country. Racking spans and attachment spacing have to be engineered for the actual wind zone your address sits in, not a generic default.
- Every roof penetration is a future leak if it is done badly. In a climate with this much rain, flashing quality is not a detail. It is the whole ballgame.
The IronRidge XR rail family, explained plainly
IronRidge’s main residential product is the XR Rail family. There are three rails, and the difference between them is how far they can span between attachment points before they need support.
- XR10 — the lightest rail, designed for shorter spans and low-load roofs. Common on straightforward residential installs in mild wind and snow zones.
- XR100 — the mid-range workhorse. This is what ends up on most Pacific Northwest homes, because it handles our wind and snow loads without over-building.
- XR1000 — the heavy-duty rail, built for long spans and high load. Comes into play on commercial roofs, high-wind exposures, and homes at elevation with real snow load.
A longer span means fewer roof penetrations, which means fewer places water can eventually get in. That is the practical reason a good installer cares which rail goes on your roof. According to IronRidge’s published XR Rail specifications, the three rails are rated as follows: XR10 spans up to 6 feet with moderate load capability; XR100 spans up to 8 feet with heavy load capability; and XR1000 spans up to 12 feet with extreme load capability. IronRidge backs the range with a 25-year warranty against defects in materials and manufacturing.
What about roof attachments and flashing?
IronRidge’s FlashFoot2 is the attachment most commonly used on composition shingle roofs. It combines the mount and the flashing into one piece, and it seats under the shingle course above it so water sheds over the top rather than pooling at a bolt head.
For our climate, that integrated approach is the point. A mount and a separate flashing installed by two different hands is a leak waiting to happen. One piece, installed correctly, is not.
Tile, metal and standing-seam roofs each use different attachments. If your quote does not say which attachment is going on your specific roof type, ask.
Is IronRidge certified and warrantied?
IronRidge systems are UL 2703 certified, which covers mechanical loading, bonding and grounding for rooftop mounting systems — the certification your permit inspector will care about.
IronRidge offers a 25-year limited product warranty on its racking. Worth understanding: that covers the racking hardware itself. It is separate from your panel warranty, your inverter warranty, and your installer’s workmanship warranty. At Sunbridge we back our own work with a 10-year craft warranty alongside the 25-year product warranties on equipment.
How to read racking on a solar quote
Most quotes bury this. Here is what to look for:
- Is the racking named at all? “Standard racking” is not an answer. You should see a manufacturer and a product line.
- Which rail and which attachment? The right answer depends on your roof type, pitch and wind zone — so a real answer means someone actually looked at your roof.
- Was the array engineered for your wind and snow zone? Ask what values were used. A local installer will know the numbers for Clark County or the Gorge without looking them up.
- Who warranties the roof penetrations? The racking warranty does not cover a leak caused by bad installation. Your installer’s workmanship warranty does.
Why Sunbridge uses IronRidge
We have been installing solar across NW Oregon and SW Washington for over 15 years, and racking is one of the places we do not experiment. IronRidge’s spans let us reduce roof penetrations, the FlashFoot2 holds up in our rain, and the engineering support means we can size a system properly for a windy ridge in Washougal instead of guessing.
It is not the flashiest part of your system. It is the part that has to still be doing its job in 2050.
Frequently Asked Questions
Is IronRidge racking good?
It is one of the two or three racking systems we would put on a Pacific Northwest roof without hesitation — engineered for real wind and snow loading, with attachment and flashing hardware designed as a system rather than assembled from parts.
Why does racking matter more in the Pacific Northwest?
Because of wind and water. Gorge outflow winds mean uplift is a genuine engineering number here, and our rain means every roof penetration has to stay watertight for decades. Racking is where both of those are won or lost.
What should I look for on a solar quote about racking?
The brand and series, the attachment and flashing type, and whether the design was engineered for your site’s wind and snow loading rather than a national default. A quote that does not name the racking is not a finished quote.
Does IronRidge come with a warranty?
IronRidge publishes a long-term limited warranty on its racking components. That sits alongside our own 10-year craftsmanship warranty, which covers the installation itself — the two are separate and both matter.
Can racking be reused if I replace my roof?
Usually the rails and modules come off and go back on, while flashing and some attachment hardware is replaced as part of the new roof. If your roof has under about eight to ten years left, it is cheaper to reroof before installing than to pay for removal and reinstallation later.
Frequently asked questions
Is IronRidge good racking?
Yes. IronRidge is one of the most widely used residential solar racking systems in the United States, is UL 2703 certified, and carries a 25-year limited product warranty. It is a standard professional choice rather than a premium upgrade.
How long does IronRidge racking last?
IronRidge carries a 25-year limited product warranty on its racking. The aluminum and stainless steel construction is designed to outlast the panels mounted on it.
What is the difference between XR10, XR100 and XR1000?
They are the same rail family with different load ratings. XR10 handles the shortest spans and lightest loads, XR100 is the mid-range rail used on most Pacific Northwest homes, and XR1000 handles the longest spans and heaviest wind and snow loads.
Will solar racking damage or leak through my roof?
Not when it is installed correctly. Modern attachments like IronRidge’s FlashFoot2 integrate the mount and flashing into one piece that seats beneath the shingle course above it. Leaks come from poor installation, not from the racking itself — which is why the installer’s workmanship warranty matters as much as the product warranty.
Does IronRidge racking work on metal or tile roofs?
Yes. IronRidge makes attachment options for composition shingle, tile, metal and standing-seam roofs, as well as ground mounts. The right attachment depends on your specific roof, which is something an installer should confirm on site.

The XR rail family in 2026
IronRidge sells three residential rails, and the difference between them is span — how far the rail can reach between attachment points before it needs another hole in your roof.
- XR10 — spans up to about 6 feet, intended for light or no snow load. Available in mill and black anodised finishes.
- XR100 — spans up to about 8 feet, the workhorse residential rail across a heavier load range. Mill and black anodised.
- XR1000 — spans up to about 12 feet, for extreme climates and commercial work. Mill finish only.
Longer spans mean fewer attachments, which means fewer penetrations in a roof that gets rained on for eight months of the year. That is the quiet reason rail choice matters more here than the spec sheet suggests. The exact permitted span for your house depends on wind exposure, elevation and snow load, and comes from IronRidge’s current engineering tables at design time rather than from an article.
Which one goes on a Pacific Northwest roof
For most of Clark County and the Portland metro at valley elevation, XR100 is the sensible default — it handles our wind exposure with margin and keeps penetration counts sensible. XR10 can be appropriate on a sheltered site with genuinely negligible snow. Above roughly a thousand feet, in the east county hills or the Cascade foothills, the heavier options start to earn their place.
The Columbia River Gorge corridor is its own case. Wind exposure there is in a different category from a sheltered west-metro street, and it drives attachment spacing regardless of which rail is specified.
FlashFoot2, which is the part that keeps your roof dry
The rail holds the panels. The attachment is what goes through your shingles, and in this climate it is the component that actually matters.
FlashFoot2 is IronRidge’s standard composition-shingle attachment: a three-tier water seal, an 8 by 12 inch flashing profile, UL 2703 certification, and testing to TAS-100, which is a wind-driven rain standard. Wind-driven rain is not an abstraction here — it is a Tuesday in November with weather coming up the Gorge.
IronRidge also offers Halo UltraGrip and QBase as alternative shingle attachments. Which one is right depends on the roof deck, the shingle condition and how the rafters actually sit, which is one of several reasons an installer should be in your attic before quoting.
Warranty and where it comes from
IronRidge covers its racking systems for 25 years. The company is headquartered in Hayward, California, manufactures there, and also uses at least one contract manufacturer in Arizona — a normal arrangement in this industry.
A racking warranty is a different kind of promise from a panel warranty. Nobody claims performance on an aluminium rail; what you are covered for is the hardware not failing structurally or corroding. In a wet climate, corrosion resistance and the quality of dissimilar-metal contact points are the parts of that promise that get tested.
The questions worth asking any installer about racking
- What wind speed and exposure category did you design to for my address? A real answer names both. In the Gorge that answer should be noticeably different from a sheltered neighbourhood.
- How many roof penetrations will this design need, and why that many? Fewer is better in this climate, within what the engineering allows.
- Which attachment are you using on my roof type, and did anyone look at my rafters? Attachment spacing depends on where the framing actually is.
- Where will snow shed? An array makes a roof slippery. What sits under the shedding edge is worth thinking about before the first wet snow.
What is the difference between IronRidge XR10, XR100 and XR1000?
Span. XR10 reaches about 6 feet between attachments and suits light or no snow load, XR100 about 8 feet across a heavier load range, and XR1000 about 12 feet for extreme climates and commercial work.
Which IronRidge rail is best for the Pacific Northwest?
XR100 is the sensible default for most valley-elevation roofs in Clark County and the Portland metro. Heavier options make sense above roughly a thousand feet, and Gorge wind exposure affects attachment spacing regardless of rail choice.
Will IronRidge racking leak on my roof?
Correctly installed FlashFoot2 attachments use a three-tier water seal and are tested to a wind-driven rain standard. In this climate the flashing detail and installation quality matter more than the brand name on the rail.
How long is the IronRidge warranty?
IronRidge covers its racking systems for 25 years. That covers structural failure and corrosion rather than performance, since a rail has no output to guarantee.
Does longer rail span mean fewer holes in my roof?
Yes, and that is a real advantage in a wet climate. Fewer attachments mean fewer penetrations, though the permitted span depends on your wind exposure, elevation and snow load.
Where is IronRidge made?
IronRidge is headquartered and manufactures in Hayward, California, and also uses at least one contract manufacturer in Arizona for rail components.
