Add eave and rake lengths, apply a cut/waste allowance, estimate how many stock pieces to buy and calculate installed cost per linear foot.
Use that as a screening range only. Metal type, removal, fascia condition, corners, roof height, access and whether the work is part of a full reroof can change the installed rate.
Enter the lengths where drip edge is actually specified for your project. The calculator will round the purchase quantity up to whole pieces.
Drip edge is usually sold and estimated in linear feet. A broad 2026 replacement benchmark of $1.50–$9 per linear foot can help screen a budget, but a small repair and a full reroof detail are not the same job.
Add the eave and rake lengths included in the project, then add a modest allowance for cuts and overlaps. Divide by the stock piece length and round up. For example, 200 measured feet with a 10% allowance becomes 220 planned feet, or 22 ten-foot pieces.
The number of pieces answers what to purchase. The installed rate can also include removal, fastening, corners, access, fascia condition and integration with underlayment and roofing. Keep the two numbers separate when comparing quotes.
The broad replacement benchmark is based on HomeGuide's 2026 roof repair cost guide. Quantity math is transparent: measured length × allowance, then rounded to whole stock pieces.
Published 2026 consumer cost guides show a broad replacement range around $1.50–$9 per linear foot. Actual quotes can fall outside that range.
Divide planned length after allowance by 10 and round up. The calculator does this automatically.
A small allowance can cover cuts and overlaps, but use the project layout and product lengths rather than adding arbitrary waste.
It may be, but ask the contractor to identify new versus reused edge metal and whether removal and fascia repair are included.
