Set-Up > Flashings
What it does
The Flashings setup allows you to define all trim and flashing materials including ridges, valleys, fascias, gutters, barges, aprons, and custom flashings. You can configure pricing, estimation methods, accessories, stock lengths, and special options like fall protection systems.
🧾 Version compatibility notice
Important: From version 5.8 onwards, an extra variable (gauge) has been added which makes files not backward compatible with previous versions. The text file Flashing.csv describes all trim prior to V5.8 and if it exists will be read into the program. All new trim defined in V5.8+ is saved to Flashing_V6.csv.
🔧 Main flashing definition fields
Field | Description |
Type of flashing | Drop-down list with categories: Ridge, Valley, Fascia, Gutter, Barge, Apron, Batten, Box gutter, User-defined, or Step |
Supplier | Lists all suppliers in the flashings database or enter new supplier name directly |
Finish | Lists all finishes or enter directly. Use "Painted", "Colour", or "Color" to prompt for paint colour selection |
Fastener code | Lists fasteners from fastener database or enter new fastener code directly |
Description | User-defined description to identify this flashing |
Product code | Product code for ordering purposes - this links products with accessories, pricing and labour |
Fasteners per m | Number of fasteners per metre (or per foot) for estimation purposes |
Minimum Length | Sets minimum length for any flashing when ordered. Any calculated length shorter than this will be modified to the minimum length (metric units only) |
Maximum length | Maximum length you can order (or 0 if no maximum/cut to length) |
Gauge | Base metal thickness of the selected trim material |
Cost method | Either per metre (or per foot) or per length |
Cost per unit | Cost per unit based on the above cost method setting |
Estimation method | How Roof Wizard estimates the number of lengths of this flashing |
Control Buttons
Button | Function |
Select | Select an existing flashing from a list |
Delete | Delete the current flashing |
Add | Add a new flashing definition (must be unique) |
Accessories | Associate accessories to the current flashing |
Stock-Lengths | Associate a list of stock lengths and costs to the current flashing |
Cancel | Cancel all changes made |
OK | Save the changes made |
💡 Pay rate scheduling
You can nominate a specific pay rate schedule for each flashing:
Option | Description |
None | Do not calculate a labour charge for this item |
Default | Use the default method (e.g., ridge flashing uses ridge labour item) |
Current | Use a designated line item in the currently selected pay schedule |
Select from list | Choose from previously defined pay rates from both metal pay and tile pay schedules |
Pay rate line item: Use designated user-defined line item in pay schedule under Set-Up > Pay Rates > Metal Pay Rates - Variable or Metal Pay Rates - Fixed > Add-User. This provides special rates for special install processes like scribing or caulking.
The link is saved to FLPayLink.dat as shown here in Excel.
💡 Search and filtering
To find required flashings during setup, use the Search option or filter by Type to reduce long lists to manageable short lists.
🧾 Quote groups and PDF linking
Roof Wizard supports Quote Groups for splitting estimates into various groupings, and you can link PDF files (typically product descriptions) to each material item. A file called PDFS.CSV is created containing the product code and PDF filename. If a Drawing Report of type PDFReport is defined under Drawings, it will compile all PDFs for printing.
Show Angle Option
What it does
The Show Angle option in Preference settings displays the angle of bend for trim, which is the angle between adjacent roof planes. This becomes part of the flashing cutting list information to assist correct fabrication.
How to use it
Double-click the cell in the dialog
The fabrication angle of bend will display in the flashing report cutting list summary
When checked, the software adds the angle of bend to roof plan annotation
Note: Line annotation only applies when trim is manufactured 'cut to length' or fixed length per run. For stock length 'sticks' with 'combine lengths' estimation method, lines are not annotated unless you have multiple bend angles and set estimation method to calculate each run separately.
Fall Protection
What it does
Fall Protection allows custom application of fall barriers to the roof perimeter or any other lines. It's a subset of the Flashings definition process.
How to set up fall protection
Use Set-Up > Flashing command
Set the Finish to "Fall Protection"
Define and quantify as a linear item (cost per metre or per foot)
Fall protection options include ###Fall1Name, ###Fall2Name, ###Fall3Name along with corresponding quantity and cost variables for detailed reporting output.

Flashing Estimation Methods
Available estimation methods
Method | Description |
Split each run up to the maximum length | Measures each run and divides into equal length pieces not exceeding maximum length. Includes run and lap allowances |
Split each run into maximum length pieces | Measures each run, then supplies enough maximum length pieces to cover the run. Includes run and lap allowances |
Split total run length into maximum length pieces | Adds all runs of this flashing, then supplies enough maximum length pieces to cover entire length. Includes run and lap allowances |
Split each run into stock length pieces | Measures each run, then uses defined stock lengths to supply combination of pieces to cover run. Includes run and lap allowances |
Split total run length into stock length pieces | Adds all runs of this flashing, then uses stock lengths to supply combination of pieces to cover total length. Includes run and lap allowances |
Information is saved to Flashing_V6.csv in the User folder when you select OK after defining a new part.
Flashing Accessories
What it does
The Accessories feature allows you to define up to 30 accessories per flashing (10 per page across 3 pages). Each accessory can be designated as either Labour [L] or Material [M] item.
🧾 Accessory definition fields
Field | Description |
Accessory name | Name by which you identify this accessory (e.g., Gutter clip, joining plate) |
Product code | Code by which you identify this accessory |
Supplier | Accessory supplier's name (might differ from flashing supplier) |
Gauge | Gauge of accessory material |
Finish | Finish for accessory. Default is host flashing finish. Use "Colour", "Color" or "Painted" to adopt host flashing colour |

[X] | Deletes the accessory item from the list |
🛠 Special fascia and gutter combinations
Fascia flashings: The [Fascia Alone] button toggles between [Fascia Alone] and [Fascia with Gutter]. This allows you to define different accessory sets for fascia used alone versus fascia-gutter combinations.
Gutter flashings: Similar feature with [Gutter alone] and [Gutter with fascia] options for different accessory sets.
Note: You can copy accessory items from corresponding items previously defined to save setup time. Maximum 2000 accessory line items total in the access2.csv file.

Stock-Lengths
What it does
Stock-Lengths allows you to enter up to 25 different stock lengths and their associated costs for each flashing.
How to use it
Click the Stock-Lengths button
Enter stock length followed by cost for that length
You can use any cell - order doesn't matter
These lengths are only used with 'Split into stock length pieces' estimation methods
Costs are only used if you selected 'per length' as the cost reporting method
🛠 Stock length selection algorithm
The system uses an algorithm based on standard deviation and waste. Each length is used as a seed, then the next best length is found. If multiple solutions use the same number of pieces, the one with lesser standard deviation is chosen. If adding one more piece reduces waste, that solution is used.
Note: Even with multiple stock lengths available, you will only get maximum 2 lengths calculated for each run.
⚠️ Important notes
Product Code is the key linking element for all products
Maximum 2000 accessory line items total across all flashings
