Stanley 11-939 Roofing Utility Blades 3 Pack

Product Description

The STANLEY 11-939 is a 3-pack of roofing utility blades designed for cutting asphalt shingles, roofing felt, and similar roofing materials. These blades fit standard utility knives and deliver the heavy-duty edge geometry required for clean cuts through tough roofing substrates. Roofers and sheet metal contractors reach for purpose-built roofing blades when a standard utility blade dulls too quickly or tears material instead of cutting cleanly. The 3-pack format keeps replacement blades on hand during active work without the need to stop and reorder mid-job.

These blades are suited for residential and commercial roofing applications where a utility knife is the primary cutting tool. Typical tasks include trimming shingle overhangs, cutting felt underlayment to length, and scoring rigid insulation board. The pack format makes them practical for contractors who maintain a stocked tool bag on every job site.

Key Features

• Purpose-built blade geometry for cutting asphalt shingles and roofing felt
• 3-pack format reduces mid-job downtime from blade changes
• Compatible with standard utility knife handles
• Compact and lightweight at 0.04 pounds per pack

Compatibility

Designed as a replacement roofing utility blade for use with standard utility knife handles that accept common trapezoidal blade formats.

Installation Notes

Blade changes should be performed by a qualified roofer or tradesperson following the tool manufacturer's blade-change procedure. Always retract or cover the blade before handling and store unused blades in the original packaging to prevent accidental contact. Follow applicable OSHA hand-tool safety guidelines when working with utility knives at height.
