Metal Shingles in Pompano Beach, FL

Steel and aluminum are the two common metals for shingles. Steel is the stiffer of the two and usually the cheaper. In the HVHZ, steel shingles must be at least 26 gauge with a G-90 zinc coating. Unlike stone-coated steel, a painted shingle has a smooth face with no granules, so its color depends on the paint system. Ask whether the finish is PVDF or a lower-grade paint.

Aluminum resists rust, which is the reason to choose it near salt water. One aluminum shingle with a current Miami-Dade approval shows how these systems work:

• Thickness. 0.032 inch minimum, above the code floor of 0.025 inch.
• Lock. Panels go on left to right and interlock with the panel beside them.
• Hold-down. A continuous clip runs along the long edge of each panel and is nailed to the deck.
• Rated uplift. 76 pounds per square foot.

That approval lists slopes of 3:12 and steeper, while the HVHZ slope table sets 4:12 for metal shingles. Ask the roofer to measure your pitch and confirm it meets both. For more on roofing near salt water, see the aluminum page.

Slate-look shingles are stamped with the flat, layered edge of natural slate, usually in steel. HomeGuide puts them at $300 to $500 per square for the material alone and $600 to $1,400 per square installed. HomeGuide describes metal slate as a cheaper, lighter stand-in for natural slate, so you get the lines of a slate roof without loading the framing with stone. Color is the main choice: charcoal and dark gray are the usual slate shades, but they hold more heat than a light finish.

Asphalt-look metal shingles copy the layered tabs of an architectural shingle, so a house keeps its familiar roofline after the change to metal. They are also the metal product the HVHZ code allows over one existing layer of asphalt shingles, as long as the deck is solid and sound. Recover or tear-off is its own decision, covered on the tile-to-metal conversion page.
