Steel is the toughest metal cladding available for residential work. It is non-combustible, will not rot or attract pests, and resists denting considerably better than aluminum, though large hail can still mark it. Gauge and profile both affect how well it holds up.
At GS Exterior Experts, we install steel siding across the Denver metro and can advise on the gauge that suits your exposure.
Steel is the strongest metal cladding used residentially and typically lasts 40 to 70 years. The panel usually outlasts the coating, so the finish warranty matters more than the substrate when comparing products.
Steel will not warp, crack, rot, or attract pests, and an occasional wash keeps it clean. Worth knowing that steel can rust if the coating is breached, so scratches and cut edges should be touched up rather than left.
Steel is a non-combustible material, providing an extra layer of fire protection for your Denver home.
If you’re considering steel siding replacement in Denver, there are various options available. You can find choices that match your home’s style and fit within your budget.
Steel expands and contracts with temperature, so panels have to be fastened to allow movement rather than pinned tight. Cut edges also need sealing, since bare steel at a cut line is where corrosion starts.
We install accordingly, and we will walk you through gauge and coating options before you commit rather than after.
We back our installation with a written workmanship warranty, and the panels carry their own manufacturer warranty on substrate and finish. We provide the terms of both before work begins.
Yes, you can sing a direct-to-metal (DTM) paint or a primer-paint combo formulated for metal. Steel siding usually arrives with a factory finish, so check whether it’s chalking, faded, or otherwise due for a repaint before starting, and address any rust spots with a corrosion-resistant primer first. Apply on a dry day with mild temperatures: neither too hot nor too cold for proper adhesion and cure time.
Steel siding can last 40 to 70 years, depending on the coating system, gauge, installation, exposure, and maintenance. That panel’s lifespan exceeds the finish warranty. However, most coating systems carry a warranty in the 25 to 40-year range against fading or chalking, so the finish may need attention well before the steel itself is due for replacement.
It can, though steel resists denting considerably better than aluminum or thin metal panels. Heavier gauges and textured or profiled finishes handle hail far better than smooth flat panels. Dents are usually cosmetic rather than a failure of the weather barrier, but if your neighbourhood takes regular hail it is worth discussing gauge before you commit.
