FAQs
What is an exposed-fastener metal roofing system?
An exposed-fastener system is a panelized metal roof in which the screws pass through the face of the panel and are visible after installation. The fasteners are fitted with neoprene washers that create a watertight seal against rain and wind. Because the panels are wider and the fastening pattern is straightforward, exposed-fastener roofs are typically faster and less expensive to install than concealed-fastener (standing-seam) systems, making them a popular choice for homes, barns, and light-commercial buildings in and around Tullahoma.
Is an exposed-fastener metal roof a good choice for Tullahoma’s climate?
Yes. Tullahoma’s humid-subtropical climate brings hot summers, occasional severe thunderstorms, and the possibility of heavy rain events. 29- to 26-gauge steel panels with galvanized or Galvalume coatings perform well under these conditions and resist rust. When properly fastened to code, the roof can handle wind gusts common during spring storms. The high solar reflectivity of modern paint systems also helps reduce attic temperatures and cooling costs during Tennessee’s hot, sunny months.
How long will an exposed-fastener metal roof last, and what maintenance does it require?
Service life ranges from 30 to 45 years when quality panels and screws are used. The main maintenance item is periodic fastener inspection: because temperature swings can cause slight panel movement, screws may back out over time. We recommend a roof check every 5–7 years to retighten or replace fasteners and inspect washers. Keeping valleys and gutters clear of leaves—which are plentiful around Tullahoma in the fall—also preserves drainage and prevents premature corrosion.
How does the cost of an exposed-fastener roof compare with standing seam or asphalt shingles?
In the Tullahoma market, installed costs for exposed-fastener metal roofing generally run $4–$6 per square foot. That’s about 30–40 % less than a comparable standing-seam roof and 15–25 % more than a premium architectural shingle roof. However, the metal roof lasts two to three times longer than shingles and may lower homeowners-insurance premiums by up to 15 % because of its superior fire and hail resistance. Over a 40-year horizon, most owners find the metal option to be the better value.
Can an exposed-fastener metal roof be installed over my existing shingles?
Often, yes. Tennessee building codes allow a metal-over-shingle installation provided there is only one existing shingle layer and the decking is sound. We add a vented synthetic underlayment or a 3-D batten system to create an air gap that improves energy efficiency and reduces moisture buildup. By avoiding a tear-off, you save on labor and landfill fees, and the extra insulation value can help cut cooling bills during Tullahoma’s warm season.
What color and profile options are available?
We stock classic 36-inch-wide “R-panel” and “ag-panel” profiles in 24 standard colors certified by the Metal Construction Association for long-term fade resistance. Specialty finishes such as matte black, metallic copper, and textured “crinkle” paints can be special-ordered. All colors carry a 40-year finish warranty. If your property is subject to Tullahoma’s historic-district guidelines, earth-tone and low-gloss options are available that meet local aesthetic requirements while still providing modern performance.
