Architectural Sheet Metal in Mehlville, MO

Architectural Sheet Metal in Mehlville, MO

Architectural sheet metal is an investment in durability, waterproofing, and curb appeal for Mehlville homes and businesses. With hot, humid summers, heavy spring storms, and occasional freeze-thaw cycles in the St. Louis region, properly designed and installed metal features protect building envelopes, manage water, and reduce long-term maintenance. As a family-owned, union-based St. Louis contractor with in-house design and fabrication capabilities, we specialize in custom architectural sheet metal in Mehlville, MO that coordinates with architects, builders, and existing building systems.

What we build: common architectural sheet metal projects in Mehlville, MO

• Custom bay window cladding and metal trims: tailored profiles that weatherproof projections while preserving historical or modern aesthetics.
• Metal roofing systems: standing seam and batten seam roofs, retrofit metal over existing substrates, and fully ventilated assemblies for durability and thermal performance.
• Flashings and counterflashings: roof-wall intersections, chimneys, parapets, and window perimeters precisely formed to stop leaks where shingles and siding meet penetrations.
• Gutters and downspouts: seamless, sized and sloped for local storm runoff rates to prevent foundation and landscape damage.
• Decorative metalwork: cornices, coping, canopies, fascia, and ornamental panels for façade enhancement and branding.
• Architectural metal panels: composite and single-skin panels for commercial facades, canopy soffits, and rainscreen applications.

Materials and finishes suitable for Mehlville conditions

Selecting the right material is essential for longevity in Mehlville’s climate. Common options include:

• Galvalume (zinc-aluminum coated steel): excellent corrosion resistance and cost-effective for roofs and flashings.
• Aluminum: lightweight, naturally corrosion-resistant, ideal for gutters, soffits, and coastal-like humidity resistance.
• Copper: premium, long-lasting, and develops an attractive patina; ideal for historical restoration and decorative elements.
• Stainless steel: high durability and resistance to staining for specialty applications.
• Zinc: self-healing patina and long service life for roofs and cladding.
• Painted/coated systems (Kynar/fluoropolymer): broad color selection with UV and weather resistance for aesthetic façades.

Choosing the right gauge, coating, and fastener system is tailored to each project’s exposure, expected lifespan, and aesthetic goals.

Design, fabrication, and installation process

Our approach is collaborative with architects and builders to ensure constructible, code-compliant results:

• Site survey and assessment: on-site measurements, substrate verification, and moisture/infiltration diagnostics to identify problem areas and coordination needs with roofing or HVAC systems.
• Shop drawings and mockups: precise shop drawings and physical mockups to confirm transitions, weathertight details, and finish selections before fabrication.
• In-house fabrication: using our shop capabilities to form panels, flashings, gutters, and decorative elements to exact tolerances, which shortens lead times and reduces field adjustments.
• Prefinished and field finishes: options for factory-applied Kynar or coil coatings, or field finishing when necessary for seamless integration.
• Installation and coordination: union-trained crews install to manufacturer specifications and local codes, coordinating with roofing, masonry, glazing, and mechanical trades to maintain experienced sequencing and waterproofing integrity.
• Quality assurance: post-install inspections, water tests where applicable, and documentation of as-built conditions for owner records.

Common architectural sheet metal issues in Mehlville and solutions

• Leaking flashings at roof-wall transitions: often caused by improper flashing laps or failing sealants; solution includes replacing flashings, adding counterflashing, and correcting substrate issues.
• Clogged or undersized gutters causing overflow and foundation concerns: resolved by installing correctly sized seamless gutters, adding leaf guards, or regrading downspouts.
• Metal roof panel movement and loud thermal expansion noises: anchored systems with proper clips and expansion joints mitigate movement and noise while preserving weathertight integrity.
• Corrosion of fasteners or panels in humid environments: specified stainless or coated fasteners and appropriate material pairings prevent galvanic corrosion.
• Deteriorated decorative elements and cornices: restoration through custom-fabricated replacements that match existing profiles and finishes.

Project examples and how we approach them

• Historic storefront restoration: custom-formed copper cornices and flashings matched to original profiles, coordinated with masonry repairs and city preservation requirements.
• Residential bay window cladding: insulated metal panels and continuous flashings fabricated to tight tolerances to eliminate leaks and provide long-lasting curb appeal.
• Commercial metal roof replacement: full assembly replacement using galvalume standing seam panels, upgraded underlayment, and detail corrections to improve drain performance during heavy summer storms.

These project types reflect the attention to detail needed for lasting results in Mehlville’s mixed residential and commercial neighborhoods.

Benefits of professional architectural sheet metal work

• Longer service life compared to many other cladding materials, reducing total cost of ownership.
• Improved waterproofing and building envelope performance, decreasing interior repairs and mold risk.
• Energy performance gains from reflective coatings and properly detailed roof assemblies.
• Aesthetic flexibility, from traditional copper to modern metal panels that enhance property value.
• Coordination advantage when sheet metal is integrated by a full-service design-build team experienced with local codes and union craft standards.

Maintenance recommendations for Mehlville properties

• Inspect gutters and downspouts at least twice a year and after major storms; clear debris and check hangers.
• Check roof-to-wall flashings and sealant joints annually for cracks or deterioration from freeze-thaw cycling.
• Keep metal finishes free of acidic residues and contact with dissimilar metals that can accelerate corrosion.
• Schedule periodic professional inspections, especially after severe weather, to catch issues early and preserve warranties.
