Xactimate Ridge Cap (RFG RIDGC): Standard vs. High-Profile and Why It Matters

Open any adjuster estimate on an architectural shingle roof claim and scroll to the ridge line item. Nine times out of ten you'll see RFG RIDGC written at a standard unit price, with no distinction for the fact that the home has laminated architectural shingles that require a matching high-profile ridge cap. That single misclassification is worth 300 to 900 dollars on a typical suburban roof, and it shows up on nearly every file that crosses a Farmers, Allstate, State Farm, or Liberty Mutual desk.

Ridge cap pricing in Xactimate is not one-size-fits-all. There are at least three distinct codes (RFG RIDGC, RFG RIDGH, and specialty versions for premium shingles), each with its own unit price, each appropriate for a specific shingle system. Write the wrong code and you either underbill the job (and cut into your margin) or you overbill and get the supplement kicked back. Write the right code with the right LF and you get paid fairly on every claim.

This guide covers the difference between standard ridge cap and high-profile ridge cap, how to measure ridge-plus-hip linear footage correctly, when to use RFG RIDGH versus RFG RIDGC, the specific underpayment pattern of adjusters writing 3-tab ridge on architectural roofs, and the supplement language that gets these items approved without a second round.

What Ridge Cap Is and Why It's Priced Separately

Ridge cap is the purpose-made shingle product installed along the roof ridges and hips to seal the horizontal top edges and the sloped corner intersections where roof planes meet. It is not the same product as field shingles. It is thicker, pre-cut to a specific length, and designed to bend over the ridge without cracking.

Decades ago, when almost every residential roof was 3-tab asphalt, contractors would cut field shingles into thirds on site and use those pieces as ridge cap. That practice is obsolete on any modern laminated or architectural shingle roof. Architectural shingles are too thick to fold cleanly, they will crack along the fold, and every major manufacturer (GAF, Owens Corning, CertainTeed, Atlas, Malarkey, IKO) now requires a matching purpose-made ridge cap product with their architectural systems.

Because the ridge cap is a separate product with its own labor profile (unit installation, more linear feet per bundle, often longer exposure), Xactimate prices it on its own line. That line should match the shingle system installed on the field.

RFG RIDGC vs. RFG RIDGH: The Code Breakdown

Here are the main ridge cap codes you will encounter in Xactimate. Pricing varies by region and is updated periodically in the Xactimate database; the ranges below reflect typical 2026 pricing across most US markets.

The critical delta for most supplements is between RIDGC (standard) at about 5 dollars per LF and RIDGH (high-profile) at about 8 dollars per LF. On a roof with 180 LF of ridge plus hip, that's a 540-dollar underpayment when an adjuster writes the wrong code.

What High-Profile Means

High-profile ridge cap is manufactured specifically to match the visual thickness and color blend of architectural shingles. Products like GAF TimberTex, Owens Corning ProEdge Hip and Ridge, CertainTeed Shadow Ridge, and Atlas Pro-Cut are all high-profile products intended to pair with their respective laminated field shingles.

If you install a standard low-profile ridge cap on an architectural field, the ridge line looks visually out of proportion (thinner than the field shingles immediately below it), and the aesthetic mismatch is one of the first things an owner or future buyer notices. More importantly, the wind warranty on the field shingle system may be voided if the manufacturer's matching ridge cap is not used per their installation instructions.

Matching Ridge Cap to Architectural Shingles

Xactimate's field shingle code tells you what ridge code should accompany it. Here's the quick cross-reference.

Rule of thumb: if the field is written as RFG 240 or higher, and the adjuster wrote RFG RIDGC for the ridge, you have a direct supplement. The codes must match the system.

LF Calculation: Ridge Plus Hip

Ridge cap LF is measured as the total linear footage of both ridges (horizontal) and hips (sloped from ridge to eave at corners). Adjusters sometimes write only the main ridge LF and omit hips entirely, or they measure from satellite imagery with no pitch correction and come up short.

What Counts Toward Ridge LF

• Main ridge: The horizontal line at the peak of each gable or hip roof section. Measure end to end.
• Hips: The sloped lines at the outside corners of a hip roof. These run from the ridge down to the eave. Measure along the slope, not the horizontal plan.
• Dormer ridges: The peak of each dormer. Small, but they add up on a cut-up roof.
• End caps: The short caps that wrap the end of a ridge at the rake. Minor quantity but typically included.

Quick Sanity-Check Formula

Example: 2,800 SF simple hip roof with 6/12 pitch.

Main ridge: approximately 36 LF. Four hips: each approximately 18 LF slope length = 72 LF total. Two dormer ridges: 5 LF each = 10 LF.

Total ridge-plus-hip LF: 118 LF.

Using RFG RIDGH at $8.00 per LF = $944. Using RFG RIDGC at $5.00 per LF = $590. Delta per this roof alone = $354 in underpayment from the wrong ridge code, before you even check whether the LF itself is correct.

Always cross-reference ridge LF against the EagleView or HOVER report if one exists on the claim. Those reports break out ridge and hip separately. If the adjuster wrote 90 LF of ridge and the EagleView shows 118 LF, that's a straight quantity supplement on top of the code supplement.

The Common Underpayment: 3-Tab Ridge on an Arch Roof

This is the single most common ridge-cap underpayment pattern in the industry. The adjuster inspects the home, writes RFG 240 for the field shingles (because the roof is clearly architectural), and then writes RFG RIDGC (standard) for the ridge. It's a clerical pattern, not a fraud pattern, but it shows up so often that you should assume it's there and check for it on every estimate.

Why It Happens

Most adjusters are working from templates. The template may auto-populate RFG RIDGC as the default ridge line because that's the most common code in the legacy data set. Adjusters reviewing dozens of files per week don't always catch that the auto-populated code doesn't match the field shingle they just wrote.

There's also a training gap. Carrier adjusters and many independent adjusters aren't shingle installers. They may not know that architectural shingle systems require matching high-profile ridge cap per the manufacturer's installation instructions, or that the price differential between RIDGC and RIDGH is real and justified.

The Dollar Impact

Assume a typical suburban home with 150 LF of ridge plus hip. The adjuster wrote RFG RIDGC at $5.25 per LF = $787.50. The correct code is RFG RIDGH at $7.75 per LF = $1,162.50. That is a $375 supplement on one line item. Add O&P at 20% and tax, and you're at approximately $450 in recovered value on just the ridge code correction. Run that across 25 claims a year and you've pulled in over $11,000 that would otherwise have been left on the table.

Premium and Designer Shingle Ridge Caps

When the field shingle is a premium designer product (GAF Grand Sequoia, Grand Canyon, or Camelot II; CertainTeed Presidential; Owens Corning Berkshire; Atlas Pinnacle), the required ridge cap is not RFG RIDGH. It's RFG RIDGCS or the designer-specific code in the local Xactimate price list.

Pricing Reality for Designer Ridge

Designer ridge caps can run 11 to 18 dollars per LF installed, nearly triple the standard RIDGC rate. On a 180 LF roof that's the difference between a $900 line item and a $2,900 line item. If the adjuster wrote RFG RIDGC or even RFG RIDGH on a designer roof, you have a substantial supplement opportunity.

Documentation You Need

• A close-up photo of a shingle showing the product stamp or a piece from an unopened bundle. Product identification is critical because the designer codes are specific to the manufacturer.
• A copy of the manufacturer's installation instructions for that specific field shingle, showing the required matching ridge cap product.
• A supplier invoice or quote reflecting the actual cost of the designer ridge product for your market.

Without the product identification, adjusters will default to the cheaper code. With it, the supplement is usually approved on first submission.

Supplement Language That Gets Approved

Here is the template I recommend when you're supplementing a ridge-cap code correction. Adjust for your market, product, and the specific scope.

Supplement request: RFG RIDGH high-profile ridge cap, full R&R, correction of line 22.

Original estimate line 22 included "RFG RIDGC - Asphalt shingles (ridge cap) - composition, 150.00 LF @ $5.25 = $787.50." The field shingle specified on line 14 is RFG 240 (laminated architectural shingle, 30-year). Per manufacturer installation instructions for [GAF Timberline HDZ / Owens Corning Duration / CertainTeed Landmark], the required matching ridge cap is a high-profile product (RFG RIDGH), not a standard-profile product. Installation of standard-profile ridge cap over a laminated field shingle system does not conform to manufacturer requirements and may void the wind warranty per [cite specific manufacturer warranty language].

Requested scope: RFG RIDGH, 150 LF at $7.75 per LF = $1,162.50. Previously-allowed $787.50 to be offset. Net supplement request: $375.00 plus applicable O&P and tax.

Attach a photo of the field shingle stamp or bundle wrapper, a copy of the relevant manufacturer installation instruction page showing the required ridge cap product, and a supplier quote for the high-profile product if available.

Adjuster Pushback and How to Answer It

"Our pricing database has RIDGC as the default."

The default code is for the most common historical application (3-tab roofs). Current housing stock is overwhelmingly architectural, and RFG RIDGH is the correct code for those systems. The adjuster's own estimating tool contains both codes for a reason. Ask them to reclassify based on the actual field shingle specified on the estimate.

"We don't pay for upgrades."

High-profile ridge on an architectural roof is not an upgrade. It is the code-and-manufacturer-required scope for the specified shingle system. An upgrade would be going from a 30-year architectural to a 50-year designer product. Matching ridge to field is like-kind-and-quality, which is the policy standard.

"The old ridge looked like standard ridge cap."

On older homes it's possible the original installer used field shingle pieces as makeshift ridge. That doesn't establish the current standard for the replacement. The replacement scope follows the new shingle system's manufacturer requirements, not the legacy installation. Cite the shingle manufacturer's current installation manual.

"Ridge LF on the estimate looks about right."

Compare the adjuster's ridge LF to the EagleView, HOVER, or RoofSnap report on the claim. If one exists, the hips and ridges are broken out separately and totaled. If the adjuster undercounted hips, that is a straightforward quantity supplement on top of the code supplement.

"I can approve RIDGC at a higher rate as a compromise."

Decline. The code identifies a specific product, and the pricing attached to the code is what it is. Approving RIDGC at an inflated unit price creates audit problems for the adjuster later and leaves you on the hook for explaining the discrepancy if the claim is ever reviewed. Insist on the correct code at its correct price.

Field Cheat Sheet: What to Check on Every Estimate

Here is the quick checklist to run against every adjuster estimate that comes across your desk, specifically for ridge cap.

1. What is the field shingle code? RFG 240, RFG 300, or higher means architectural and requires RIDGH or RIDGCS.
2. What ridge code did the adjuster write? If it's RIDGC on an architectural field, that's a supplement.
3. What is the ridge LF? Does it include hips? Cross-reference against EagleView or on-site measurement.
4. Is there a ridge vent? If ridge vent is present, the ridge cap runs over the vent and the LF still counts. Ridge vent is a separate line (RFG RVA or similar).
5. Is the shingle a designer product? If yes, RIDGCS is the correct code and pricing jumps significantly.
6. Is O&P applied to the ridge line? If the claim qualifies for O&P (three or more trades), make sure ridge is included in the O&P calculation.
7. Did the adjuster include starter ridge? Some products require a starter course at the ridge. Verify per manufacturer specs.

Run this checklist on every file and you will catch ridge-code errors on most architectural-roof claims you review. For the complete review framework covering every line item, see our adjuster estimate review checklist and our Xactimate supplement list.

Why This Line Item Matters More Than Contractors Realize

Ridge cap feels like a small thing. It's one line on a 40-line estimate. But the math compounds. Between the code correction (RIDGC to RIDGH), the LF correction (adjusters miss hips), and the O&P that follows, a single ridge-line supplement typically pulls in 400 to 700 dollars on a typical residential roof. On designer-shingle homes, it's 1,200 to 2,500 dollars.

Contractors who let this go because "it's only ridge cap" are the same contractors wondering why their net per job is 6% when competitors who supplement correctly run 15 to 20%. The lines you skip are the lines you subsidize with your own labor and margin. Every miscoded ridge line is money the insurance company keeps that should be paying for materials and labor you're actually providing.

Build the habit. On every file, check the field shingle code, check the ridge code, check the LF. If any of them is wrong, write the supplement. Use the language template above. Attach the documentation. These supplements get approved at very high rates because the argument is technical and code-backed, not subjective.
