Purpose & Use

A 4-way interlocking design and hidden fasteners make ArrowLine Slate a great choice for roofs as low as 4:12. As with most painted metal shingles, ArrowLine is designed for installation on solid deck applications.

ArrowLine Slate is most often chosen for residential applications but also functions at a high level for light commercial applications as well.

A high tensile 28 gauge steel core allows ArrowLine Slate to easily handle the high winds in Florida. (not approved for HVHZ / High Velocity Hurricane Zones).

003 Steve C Arrowline Slate Charcoal Gray 001

Steve C. Creston, Iowa

This was the 3rd roof I’ve had to put on this house since 1991. 2 wind damages, with asphalt shingles gone, and 1 major hail storm last year making my decision to go with a steel roof easier. This roof won’t ever need to be replaced! Excellant material, nice finish, and excellant service from Danielle and best buy metals. This was an enjoyable experiance from purchase to installation. Thank you Best Buy Metal 🙂
