Since 2008, the patented Shingle Hog has been used by thousands of roofing contractors to tear off shingles faster, cheaper, and easier than by hand. Using the same air compressor they use for their nail gun, the tool typically tears off 17 to 20 squares per hour. Designed to be used on any roof that can be safely walked on, The Hog can be used on single layer or multi layer roofs. This durable tool is backed by a one-year warranty. The time savings creates a fast pay back, and as one roofer put it, "I feel so much better at the end of the day; I wish someone had created it 30 years ago."
