Throwback Thursday: Roofing Felt with Tar Mops
Years ago, roofers would apply hot asphalt (tar) and felt paper using tar mops. It was messy, labor-intensive, and incredibly hot work.
Today, synthetic underlayment is lighter, stronger, more tear-resistant, and provides better protection during installation.
Can you imagine carrying buckets of hot tar up a ladder in July?
