FAQs
What exactly are Classic Ribbed Panels in metal roofing?
Classic Ribbed Panels—often called “Classic-Rib” or “R-panel”—are roll-formed steel sheets with evenly spaced ribs (typically 9" on center) that run the length of each panel. Manufactured from 26- to 29-gauge galvanized or Galvalume® steel and finished with a high-performance paint system, they offer a traditional agricultural look with modern engineering. Their profile provides structural strength, efficient water shedding, and easy fastening to purlins or solid decking, making them one of the most versatile and economical metal roofing choices for residential, agricultural, and light-commercial buildings in Guild and the surrounding region.
How long can I expect a Classic Rib metal roof to last?
Properly installed Classic Rib panels routinely last 40–60 years, and many systems exceed that life span with basic maintenance. The base steel is zinc- or aluminum-zinc-coated to resist corrosion, and the baked-on paint finish (often 40-year rated) protects against UV degradation and color fade. Unlike asphalt shingles that may require replacement every 15–20 years, metal retains its structural integrity far longer, giving you two to three roof cycles of service life and a lower lifetime cost.
Are Classic Rib panels energy-efficient and environmentally friendly?
Yes. The high-reflectivity paint finishes meet Cool Roof Rating Council (CRRC) criteria, reflecting solar heat and lowering attic temperatures by up to 30 °F. This can trim cooling bills 10–25 %. The panels are 100 % recyclable at end-of-life, and up to 35 % of the steel content is already recycled. Because they weigh only 0.8–1.1 lb/ft², transportation fuel and structural demands are reduced compared to heavier roofing materials, shrinking the project’s overall carbon footprint.
Can Classic Ribbed Panels be installed over my existing shingle roof?
In many cases, yes. Building codes allow a metal-over-shingle retrofit if the current deck is sound, the existing shingles are flat, and local snow-load limits are observed. An approved synthetic underlayment or 1×4 purlins are installed over the shingles, then the metal panels are fastened through to the rafters or decking. This approach saves tear-off labor, disposal fees, and keeps old shingles out of landfills. A site inspection by a qualified roofer in Guild is essential to verify deck condition, ventilation, and fastening requirements.
What kind of maintenance does a Classic Rib metal roof require?
Maintenance is minimal. Annually, visually inspect for loose fasteners, branch debris, and sealant degradation around penetrations. Wash the roof with a mild detergent and water if pollen or industrial residue accumulates. Re-tighten exposed-fastener screws every 10–15 years if required, and replace any damaged sealant at pipe boots or flashings. Because metal is non-porous, it resists moss, algae, and rot, eliminating many of the upkeep tasks associated with asphalt or wood roofing.
How do Classic Ribbed Panels perform in severe weather typical of Guild, such as high winds, heavy rain, and hail?
Classic Rib systems are tested to UL 580 and ASTM E1592 standards, achieving wind uplift ratings exceeding 140 mph when installed with the recommended screw pattern. The interlocking overlap and rib geometry channel heavy rainfall quickly into gutters, virtually eliminating leaks caused by wind-driven rain. 29- to 26-gauge steel easily passes UL 2218 Class 4 impact testing, meaning it can withstand 2" hail without functional damage. Additionally, the non-combustible metal surface provides a Class A fire rating—an important safety advantage in wildfire-prone rural areas around Guild.
