Metal roofing in Murfreesboro

Why metal is gaining in Rutherford County

A builder-grade shingle roof in Murfreesboro lasts 12–18 years. A good architectural roof lasts 20–25. A properly installed metal roof lasts 40–60. Metal roofing Murfreesboro homeowners choose has become the option for people who plan to stay put, for the larger lots south of the city where the wind has nothing to slow it down, and for anyone who has already paid for one replacement on a house built after 2005 and does not want to pay for another.

The other reason is wind. A standing-seam panel is clipped to the deck along its full length with no leading edges to lift. Most systems we install carry a UL 580 Class 90 uplift rating, well past anything Rutherford County sees outside a direct tornado track. And metal does not grow algae streaks, which is more than you can say for the north slope of most shingle roofs in Blackman.

Standing seam versus exposed fastener

Standing seam — panels with raised interlocking seams and concealed clips. No screws through the panel face, so no gaskets to dry out. The right choice for a house. $1,200–$2,000 per square installed, so $30,000–$55,000 on a typical Murfreesboro two-story.

Exposed fastener (5V crimp, R-panel, "ag panel") — panels screwed through the face with gasketed screws. Cheaper, and fine on a garage, shop, porch or barn; you see it on outbuildings all over Christiana and Lascassas. On a house the two thousand or so gaskets each become a maintenance item around year 15. $800–$1,300 per square installed.

Both are two to three times the cost of an architectural shingle replacement. The math works if you are staying 15 years or more.

Specification matters more than brand

• Galvalume steel (aluminum-zinc coated), 24 or 26 gauge, is the standard here. We are far from salt water, so aluminum is not necessary unless you want it.
• Kynar 500 / PVDF finish every time. The cheaper polyester paints chalk and fade in Tennessee UV inside ten years, and a metal roof is the color you picked for forty.
• High-temperature synthetic underlayment under the panels. Metal in July gets hot enough to cook ordinary underlayment.
• Coated or stainless fasteners and matched trim, ridge and flashing.

What the job involves

A full tear-off — we do not install metal over shingles on a house, because the old roof holds moisture against the deck and hides rot — then decking repairs, underlayment, and panels shop-cut or formed on site to your roof's exact lengths. A 2,000 sq ft home takes three to five days. Anything at this price crosses the state's $25,000 threshold for a full Tennessee contractor license, which we carry and which you should ask any metal roofer to show you.

Trade-offs, honestly

Metal is louder in heavy rain unless the attic is well insulated, which most Murfreesboro attics are. Large hail can dent it, and we get hail a few times a spring. Many of the newer subdivisions have HOA architectural rules, and a few restrict metal or its color; check your covenants before you fall in love with a sample. If those bother you, a Class H architectural shingle roof with six nails is still a very good roof for this county, and we will say so.

Thinking about it? A roof inspection tells you whether the decking and framing are ready, and the pricing page puts metal and shingle numbers side by side.
