Here’s Why WeatherWeld Is Not Just
Your Best Roof, But Your Last Roof
Only WeatherWeld technology provides a roof solution with no seams, no joints, no leaks. Unlike other roof types that provide potential openings for water to penetrate, it’s designed for a total line of defense that can outlive your building. Make the comparisons, and you’ll agree that WeatherWeld is simpler, stronger, better.
Many factors affect the quality and reliability of your roof, from its strength and stretch, to the load strain, thickness and the detail that goes into the installation. Not only does the WeatherWeld roof system provide seamless coverage that eliminates leaks, but it also shows its superiority in a wide range of key performance categories. We invite you to review the industry comparison numbers that bear out the wisdom of selecting a long-lasting WeatherWeld roof.
Reducing the labor cost portion gives you more value for the price. And because WeatherWeld manufactures its product on-site to eliminate middle man fees and puts a greater percentage of its cost into the all-important raw materials, rather than permits, taxes and other overhead, you get a better quality roof for less money. The following graphs show the average percentage investment spent on labor costs versus materials for the most common commercial roofs.
Roof material is tested at 77 degrees Fahrenheit, stretched 1 inch per minute, to project its performance under years of stress – the higher the percentage, the better.
Historically roofs have been required to have at least 200 lbs. of strength per inch of width to avoid failure, which typically occurs on West Coast buildings at approximately 125 lbs.
Strength, thickness, and flexibility are critical factors for long-term durability.
Load Strain / Trouble Free Life
Stretch fatigues like a rubber band. Strength resists strain without stretch, like steel. Thus, higher load strain numbers indicate longer life, without system fatigue.
On-Site Installation Time
Based on a 30,000 sq. ft. building, with 2 ACs, skylights, ventilation and lighting – 5 installers.
Weight per Sq. Ft.
The key to safety is to use a roof material that is very strong, yet doesn’t overburden the structure.
