To buy roofing tar, you can visit home improvement stores like Home Depot and Lowe’s, buy online from Amazon or specialty roofing suppliers, or call local roofing contractors for bulk orders.

Most homeowners buy small amounts for repairs, while contractors purchase larger quantities for full roof jobs. The roofing industry is huge, with the U.S. roofing market valued at $81.3 billion in 2025, according to IBISWorld. Understanding where to buy tar and how to use it helps you fix roof problems quickly and affordably.

What Types of Roofing Tar Exist
There are many tar products for different jobs. Asphalt shingles remain the dominant roofing material, used on approximately 80% of residential roofs, according to RubyHome (2025). Tar is used to seal, patch, and waterproof these roofs.
Cold-process tar comes ready to use. Hot tar requires heating before application. Tar paper and tar-based sealants are lighter duty for small repairs. Built-up roofing systems use multiple layers of tar and felt for flat roofs.
How Much Roofing Tar Costs
Roofing tar prices vary by brand, size, and type. A small 5-gallon bucket of roofing cement costs $30 to $60. Larger quantities cost less per unit. According to RubyHome (2025), roof installation costs range from $4 to $40 per square foot, and tar is just one component of that total.
Budget-friendly brands cost less than premium options. Name brands like Karnak and Henry offer quality assurance. Bulk purchases for contractors cost less per gallon than retail sizes.
