What is Torch Down Roofing?
Torch down roofing consists of modified bitumen, similar in composition to asphalt. This roofing type is primarily used for flat or low-slope roofs. The installation involves melting the bitumen and adhering it to a fiberglass mesh, creating a watertight seal. This method is favored due to its long-lasting nature and minimal maintenance requirements.
