Edge Metal Takeoff by Profile: Coping, Gravel Stop, Fascia, and What ES-1 Means for Your Bid

By The Sharp Pencil team

Disclosure: Sharp Pencil sells commercial roofing takeoffs, so we have a stake in this topic.

Take off commercial roof edge metal from the roof plan and edge details, split by profile. Coping, gravel stop or fascia, and drip edge when present each get their own linear feet, plus count items the documents support. Missing or conflicting details go on the Questions tab. ES-1 is a wind-resistance test standard for many low-slope metal edges. Treat it as bid risk, not a Sharp Pencil design service. Every quantity carries its source sheet and its basis.

Edge metal takeoff in one pass (by profile, not one perimeter line)

A usable edge takeoff names the profile, the linear feet of each run, and the count items the drawings support. Blending coping and gravel stop into one "perimeter LF" hides the parts that price and fabricate differently.

The table below is a working checklist for takeoff lines. It is not a fabrication manual. It is not a code manual. It is not a Sharp Pencil warranty rulebook. Prefer the project's detail names over inventing a universal taxonomy. Sharp Pencil's takeoff workbook reports edge metal by profile. Anything the set leaves open belongs on the Questions tab, not in a guessed quantity.

Table 1. Edge metal takeoff by profile: what you usually measure
Profile (typical name on details) Where you usually find it Measure as Count / shop items when the documents support them If the set is silent
Coping Parapet / wall tops, roof plan + coping details LF along parapet (follow plan and detail width notes) Outside / inside corners or miters, end caps, splice plates / joints, continuous cleats when detailed Questions: coping profile, wall width, reuse vs replace (re-roof)
Gravel stop / metal edge flashing Low-slope perimeter without a full coping, roof plan + edge details LF along roof edge Corners, end conditions, cleats / fastener pattern notes when detailed Questions: face height, horizontal flange, profile name
Fascia (when detailed as a separate edge piece) Face of edge assembly, elevations + details LF of fascia run (do not double-count the same metal already in gravel-stop LF unless the detail shows a separate piece) Corners / returns when shown Questions: is "fascia" a separate line or part of the gravel-stop assembly?
Drip edge (steep or low where shown) Eaves / rakes on steep, sometimes low-slope details LF by eave vs rake when the set splits them Corners / overlaps only as documents support See the steep sisters for field area and the full linear list. Shingle and standing-seam method stay on those pages.
Transitions between profiles Where coping meets gravel stop, or edge meets wall flashing LF of each profile to the transition. Do not invent a blended average. Transition pieces when detailed Questions when the detail does not show how profiles meet
Interruptions (scuppers, outlets, equipment openings) Roof plan keyed openings on the edge Deduct or split runs as the plan keys them. Do not invent net lengths. Scupper sleeves / boxes only when detailed and measurable Questions when opening size is not dimensioned

Read the edge details before you trust the roof-plan perimeter

The roof-plan outline is not enough. Edge profiles, face heights, cleats, and transitions live on the detail sheets (and sometimes elevations and specs).

Edge habit before you trust a single perimeter length:

  1. Find the roof plan perimeter and any keyed edge types.
  2. Open the edge, coping, and gravel-stop details for profiles, dimensions, and substrates.
  3. Check wall sections and elevations when face height or parapet width is only there.
  4. Read spec sections for sheet metal, roofing, and any tested edge-system language.
  5. Note structural or architectural notes that speak to nailer or substrate. Do not invent structural capacity.
  6. If the plan shows one continuous perimeter but details show two or more profiles, split the takeoff. Do not average them into one line.

For the habit of reading sheets beyond the roof plan on any commercial takeoff, see the sheets a roofing takeoff has to read. This page focuses on edge and detail sheets.

Linear feet and count items that change by detail

Most edge metal is a length takeoff, but corners, joints, and cleats change the shop and install story when the documents call them out.

Measure LF along the path the detail installs (parapet centerline, outside face, or roof edge as the detail implies). State the basis on the quantity (source sheet and its basis).

Count items when shown or clearly implied by the detail: outside corners, inside corners, end caps, splice plates or joint covers, continuous cleats, starter cleats.

When the set is silent: if it never shows a shop count (for example "corners as required"), measure the LF you can prove and put the count question on the Questions tab. Do not invent a corner count from a guess about stock length. Do not invent a universal waste percent or stock-length formula as a Sharp Pencil default.

Low slope vs steep slope edges

Commercial edge metal shows up on low-slope assemblies (coping, gravel stop / fascia) and on steep-slope work (drip edge, rake and eave metal as part of standing seam or shingle). Sharp Pencil covers both.

Low slope: TPO, EPDM, PVC, mod bit, BUR. Edge lines follow the low-slope details on this page.

Steep slope: standing seam and shingle. For field area and the full steep linear list (ridge, hip, valley, dead valley, rake, eave, sidewall / endwall, starter, drip edge, gutters when in scope), see standing seam metal roof takeoff and asphalt shingle roof takeoff. On this page, split drip / rake / eave when the set splits them. Steep field math belongs on those sisters.

Mixed systems: if edge sits at a membrane-to-metal or membrane-to-shingle change, see mixed-system commercial roof takeoff once for the transition line.

What ES-1 means for your bid (estimator note, not a design manual)

For many low-slope metal edge systems, project documents and model codes reference ANSI/SPRI (or ANSI/SPRI/FM) ES-1 wind-resistance testing. Your takeoff job is to measure the edge the drawings show and to flag missing or conflicting tested-system language. It is not to design the edge, calculate ASCE 7 pressures, or certify a tested assembly.

Plain-language notes for estimators (public standards context, not Sharp Pencil rules):

Re-roof edge callout

On re-roofs, edge metal is often reuse, overlay, or replace by condition. Split reuse vs replace by profile when the set does. If the set says "replace as required" without a quantity, put it on the Questions tab. Do not invent a reuse percent.

For the full re-roof document difference (tear-off vs recover, existing conditions, hazard notes, and occupied phasing), see commercial re-roof takeoff. This page keeps the edge reuse vs replace-by-profile habit. Edge prep can also differ when tear-off vs recover is still open. That deeper fork belongs on a later page about tear-off vs recover. Existing-conditions questions also belong on the roofing RFI register.

Common misses on edge metal takeoffs

Worked example: one made-up low-slope wing with a parapet and a gravel-stop side (not a real job)

Example, made up for illustration. It is not a real building, not a Sharp Pencil job, and not a price. Use it only to see how profile-split lines and Questions split on an edge set.

Made-up assumptions:

Table 2. Made-up edge wing: measured lines vs Questions tab
Line Quantity / status Source sheet and basis
Coping (edge metal by profile) 320 LF A-301 / A-501, three parapet sides 120 + 80 + 120
Coping outside corners 2 EA A-501, two outside corners where the three parapet runs meet
Gravel stop (edge metal by profile) 78 LF A-301, 80 ft open side minus 2 ft keyed scupper opening
Scupper interruption 2 ft deducted from gravel-stop run A-301 keyed opening. Sleeve / box only if a measurable detail exists (none here).
ES-1 tested assembly / design pressure On Questions tab Spec says "ES-1 tested edge" without naming assembly or pressure
Fascia vs gravel-stop naming On Questions tab Spec names "fascia". No separate fascia detail. Do not double-count gravel-stop LF.

Arithmetic check: coping 120 + 80 + 120 = 320 LF. Gravel stop 80 − 2 = 78 LF. Two outside corners only where the coping detail supports counting them.

This example has no dollar totals, no waste percent, and no design pressures. If this wing included a steep-slope entry canopy, drip / rake / eave would follow the standing seam or shingle sister pages.

FAQ

How do I take off edge metal and coping on a commercial roof?

Take off commercial roof edge metal from the roof plan and edge details, split by profile. Coping, gravel stop or fascia, and drip edge when present each get their own linear feet, plus count items the documents support. Missing or conflicting details go on the Questions tab. Every quantity carries its source sheet and its basis.

What is the difference between coping and gravel stop on a takeoff?

Coping usually runs on parapet or wall tops. Gravel stop or metal edge flashing usually runs the low-slope perimeter where there is no full coping. Report each as its own linear feet. Do not blend them into one perimeter line. Prefer the project's detail names when the set uses different wording.

What does ES-1 mean for my roofing bid?

ES-1 is a wind-resistance test standard commonly referenced for many low-slope metal edge systems. Your takeoff measures what the drawings show and flags missing or conflicting tested-system language on the Questions tab or RFI register. Sharp Pencil does not design ES-1 edge systems and is not engineer of record.

What should go on the Questions tab when edge details are missing?

Anything the documents leave open. Missing or conflicting profile, face height, or wall width. ES-1 tested assembly or design pressure not stated. Whether "fascia" is a separate piece or part of the gravel-stop assembly. Corner or cleat counts the set never shows. Re-roof reuse vs replace quantity when the set is silent. Do not invent compliance rules inside the quantity.

What does Sharp Pencil send back on an edge-metal-heavy takeoff?

Four files: START HERE, marked-up drawings PDF, Takeoff.xlsx with a Questions tab, and the material order list. Every quantity carries its source sheet and its basis. Open edge items stay on the Questions tab. First takeoff free, one per contractor, on a job you're bidding or quoting. After that, $395 per new set of drawings, or monthly plans. Usually within one business day. Delivered within 48 hours*.

Why send your takeoffs to Sharp Pencil

The expensive miss on edge metal is not only short linear feet. It is blended profiles, skipped corners the detail required, and ES-1 or tested-system gaps that never made it onto the Questions tab.
