At Culpitt Roofing we specialize in installing one kind of roofing system. This system is called double lock standing seam metal roofing. When installed properly, with high quality materials, this roofing system is known to protect for decades. There are several different characteristics of this roofing system that contribute to its reliability and longevity.

This roofing system uses a design that does not require penetration of the roofing material. Fasteners, nails or screws, are installed into cleats under the seam of the panels. When the double lock is manufactured from the seams it complete hides the fasteners. This is not only aesthetically pleasing but serves a vital role in the functionality of the roof. A roof that has penetrations allows the possibility for those penetrations to become leaks. Especially in a climate where the temperature difference from season to season is extreme. A double lock standing seam metal roof has no penetrations through the metal roofing panels which eliminates the risk of a leak from fastener penetration.

Double lock standing seam roofing allows each panel of steel to operate independently, while maintaining a strong connection to its neighboring panel(s). The climate in the Upper Mid-West can be harsh. In the winter season the temperature can drop below 0 degrees Fahrenheit and then the temperature will rise above 100 degrees Fahrenheit in the summer months. The installation of a double lock standing seam roof allows the entire roof to expand and contract effectively during these extreme temperature variances. This is achievable because each panel of metal can independently expand and contract while the double lock ensures that the panels remain a strongly bonded single unit. This paired with the metal quality is the main factor in the longevity of the roof.

Double lock standing seam metal roofing systems are custom manufactured for each project. Sheets of metal are rolled to match the exact length of the roof. This eliminates cross seams in panels of the metal covering the roofing surface. Cross seams can become large gaps because of contraction and expansion and lead to leaks in the roof.

The material and installation process of double lock standing seam metal roofing is designed to ensure that this is your last roof. These roofs are known to be beautiful and paint technology ensures that they paint will not chip or fade for multiple decades.
Roof replacement is an important decision and a big financial commitment. Double lock standing seam roofing systems are a system designed to protect your roofing investment and your property investment beneath.
