Everything You Need To Know About DECRA Metal Roofing
Here’s why DECRA can help you protect your home during a hurricane.
Metal Roofing With A Warranty Covering Up To 120 mph Winds
One of the most damaging aspects of a hurricane is the high winds that are part of the storm. The high-velocity winds send debris of all shapes, sizes, and weights flying through the air.
DECRA metal roofing is highly impact-resistant. In the roofing industry, the UL2218 Impact test is a study performed by Underwriter Laboratories, an independent and not-for-profit organization. This test is conducted by dropping a 2’’ steel ball on the exact same spot on a roof at various heights.
The results of the test provide a roofing material will Class 1, 2, 3, or 4 designations. Class 4 roofs are the highest rating. Roofing materials with a Class 4 designation showed no sign of fracturing when the steel ball is dropped from any height during the test.
DECRA metal roofs have earned the Class 4 designation, proving the material’s ability to withstand flying debris during a hurricane.
Protection Against Wind-Driven Rain
Wind can drive rain up and under the roofing material, causing water damage to the inside of a home or business.
To determine how well a roof protects against wind-driven rain, property owners should seek a roof that passes the TAS100 test. During this test, a water rack is used to spray water on the roof samples. The water is sprayed at a rate of 8.8 inches per hour, while a wind generator is used to recreate winds of 35, 70, 90, and 110 mph for intervals of 10 minutes.
A roof that doesn’t allow wind-driven rain to reach the deck sheathing passes the test.
Stone Coated Steel Roofing That Is Lightweight
It might seem like having a heavier roof would be beneficial but the opposite is true. This is because of “shear strength”.
Shear strength is a roofing material’s ability to withstand forces that cause the structure to slide against itself internally.
When a hurricane hits, horizontal winds are what test shear strength. A heavy roof is at risk of creating a top-heavy structure that is vulnerable to horizontal winds. However, lightweight roofing, like stone-coated steel DECRA adds shear strength without adding weight.
Metal Roofing That Comes With A Lifetime Warranty
DECRA has helped thousands of property owners protect their homes from hurricanes since 1957. In fact, DECRA roofs meet the high-velocity hurricane zone requirements of Florida.
Each roof comes standard with a Lifetime Limited Warranty for winds up to 120 mph and is lab tested at twice that velocity. The roof is also guaranteed to withstand hail penetration for hail up to 2.5 inches.
If a home is sold within 20 years of the DECRA roof installation, the warranty can be transferred to the new owner.
In addition to being the perfect choice for homes and businesses in a hurricane region, DECRA has other benefits. It helps reduce energy costs by up to 25% and is low-maintenance.
