Outside of cost, shingles offer few, if any, advantages for homeowners. Conversely, metal roofing provides a wide variety of benefits. Let’s explore a few of those in-depth:

#1 Long Service Life

When it comes to longevity and service life, it’s hard to beat metal roofing. A recent white paper published by the Metal Construction Association indicates metal roofs made from Galvalume® substrates could last 60 years or more. For context, it’s important to remember that’s two to three times what you can expect from most shingles.

#2 Reduced Utility Expenses: Cool Roof Pigments & ASV
Advanced Paint Technology made reflective pigments to metal coating possible. It reflects the sun’s energy which dissipates heat transfer along with Thermal Emmittance that releases absorbed heat.

Above Sheathing Ventilation (ASV) means adding a ventilated airspace between the metal roofing and the substrate below. While not discussed frequently, ASV is perhaps even more impactful than cool metal roof pigments. This airspace enables energy to move and vent into the atmosphere instead of absorbing into the building structure. Conversely, when the warm air remains in the structure, utility expenses are increase.

Concealed Fastener Panel Styles

Concealed fastener panels are a bit different in the five distinguishing criteria. Most times, the on-center width of the major ribs is the same as the panel cover width. Concealed fastener panels also typically offer different pan conditions in between the two major ribs. Standard options range from flat to pencil ribs and striations. While the pan condition rarely affects the cost, some options like striations can greatly minimize oil canning, which is an important consideration.

Concealed fastener panels are also either symmetrical or asymmetrical in their design. Symmetrical panels are the same on both the left and right sides, whereas asymmetrical panels are different. It’s nearly impossible to tell the difference between the panel styles after installation unless you need to replace them. Symmetrical panels can easily be removed and replaced after installation. Conversely, asymmetrical panels can be difficult (if not impossible) to replace without tearing off panels back to the affected section. While repairs with metal roofing are rare, they can happen. Suppose a major storm hits your area, and a big tree limb falls onto your metal roof. If you chose a symmetrical panel system, it’s relatively simple to replace only the damaged panel. However, an asymmetrical system may require you to remove all the panels back to the impacted area.

• UL 580 Wind Uplift (Class 90)

• UL 2218 Class 4 Hail Impact

• UL 263 Fire Certification

• UL 790 Class A Fire Rating

• UL Environmental – SRI Third-Party Verified

Features and Benefits:

• Protects the roof structure from water seepage caused by ice dams and wind-driven rains

• Resists temperatures up to 250°F without degradation of the adhesive

• Seals around roofing nails, staples and screws

• Bonds directly to the roof substrate for fast and easy installation without the need for additional adhesives

• Split-release film provides easier, faster installation

• Resists cracking, drying and rotting, providing long-term waterproofing performance and low lifecycle cost

• Concealed waterproofing system will not detract from the architectural aesthetics of the primary roofing system

• Exposed rubberized asphalt bead along the membrane edge ensures watertightness of lap seams

Installation

NC300HT underlayment is applied when the roof deck is dry and the substrate temperature is 40° F (4.4°C) or higher. At temperatures below 40° F, nailing or priming should be used to temporarily hold the membrane in place while adhesion develops. NC300HT i s designed to be covered with the primary roofing system and should not be exposed to sunlight for more than 60 days. White underlayment offers exposure time of 120 days.
