Recognizing that seams are a roof’s worst enemy…allowing spaces for water to penetrate…WeatherWeld introduced an innovative technology featuring 15 gallons of liquid asphalt and eight pounds of fiber per 100 square feet. No seams, no joints, no gaps. Just five years later, we doubled the strength and thickness. Today, more than 20 years since this evolution, our roofs are still going strong. We bring all of our raw materials to the job and manufacture on site, improving quality control, expediting the job and reducing your costs by eliminating the middleman.
