Complete McElroy Metal Galvalume Double Loc Installation | Custom Flashing System with Storm-Resistant Design
Working through an insurance claim, we installed a premium McElroy Metal Galvalume roofing system featuring Double Loc panels with 1.5" Sure Lock technology and 16.5" pan width from 21" coil stock. The comprehensive scope included Epilay Ultra high-temperature underlayment, CSI 1.5" insulation boards, 2x4 battens for proper airflow, and extensive custom flashing work including valley metal, counterflashing for both stucco and stone surfaces, and vented ridge systems. This Burnet installation demonstrates how modern metal roofing delivers superior durability against Texas hail, extreme heat, and severe weather while providing energy efficiency benefits through proper insulation and ventilation design.

The homeowner reached out to Austin Pro in early May 2025 after storm damage affected their existing roof. Our canvassing team had been working the Burnet area following severe weather events and connected with the homeowner on May 3rd. The initial conversation on May 6th revealed the extent of damage and the homeowner's interest in upgrading to a more durable roofing system.
Our assessment team conducted a thorough roof inspection, documenting damage patterns and measuring the complex roofline that would require extensive custom flashing work. We identified the need for complete system replacement and evaluated the home's mixed exterior materials - both stucco and stone surfaces that would need specialized counterflashing solutions. The evaluation confirmed that a metal roofing system would provide the best long-term protection for this Hill Country location.
Working with the insurance company, we developed detailed specifications for the McElroy Metal Galvalume system with all necessary components including custom flashing, insulation, and ventilation elements. The project received approval on July 23rd after coordination with the adjuster and material selections were finalized. Planning included scheduling delivery of the 21" coil stock and coordinating the specialized metalwork required for this complex installation.
Installation began in early August with complete tear-off and preparation of the roof deck. Our crew systematically installed the Epilay Ultra underlayment, CSI insulation boards, and batten system before beginning the McElroy Metal Double Loc panel installation. The extensive flashing work required precise measurement and custom fabrication to accommodate the home's stucco and stone transitions, with particular attention to valley and ridge details.
The roofing installation was completed on August 13th with a comprehensive walkthrough to ensure all components met our quality standards. Final project documentation and warranty materials were provided to the homeowner, with the administrative closure completed on October 23rd. The finished system exceeded expectations for both weather protection and aesthetic appeal, transforming the home's exterior while providing decades of reliable performance.
This Burnet homeowner contacted us after storm damage left their existing roof vulnerable to Texas weather extremes. Located in the heart of the Hill Country, homes here face unique challenges: brutal summer heat exceeding 100°F, severe hailstorms, and the limestone-rich soil that shifts foundations and stresses roofing systems. After our initial assessment in May, we designed a comprehensive metal roofing solution using McElroy Metal products that would protect this home for decades.
Our evaluation revealed the need for a complete roofing system replacement. Given Burnet's exposure to severe weather, we recommended McElroy Metal's Galvalume Double Loc system with 1.5" Sure Lock technology. The 16.5" pan width from 21" coil stock provides superior wind resistance while the galvalume coating offers exceptional corrosion protection against Central Texas humidity and temperature swings.
The scope required extensive custom flashing work due to the home's complex roofline. We specified counterflashing for both stucco and stone surfaces, valley metal for proper water channeling, and headwall flashing where the roof meets vertical surfaces. Pitch change flashing addressed elevation transitions that could trap moisture without proper detailing.
Beginning with complete tear-off of existing materials, our crew installed Epilay Ultra high-temperature underlayment designed to withstand extreme Texas heat. This premium underlayment prevents thermal degradation that cheaper alternatives suffer during our 100°+ summer days. Over this, we placed CSI 1.5" insulation boards for energy efficiency, followed by 2x4 battens creating proper airflow channels.
The McElroy Metal Double Loc panels install with a sophisticated clip system that allows thermal expansion while maintaining weather-tight seals. Each 1.5" clip accommodates the natural movement metal experiences during temperature swings from freezing winter nights to scorching summer afternoons. Galvalume screws and rivets secure the system according to high-wind specifications required in our region.
Proper ventilation proves critical in Texas heat. We installed vented Z-bar ridge vents along the 1.5" rib profile, allowing hot air to escape while preventing weather infiltration. The ridge cap system creates a finished appearance while maintaining the structural integrity needed for storm resistance. Hip caps address complex roof intersections with the same attention to both form and function.
Eave and rake metal drip edges in matching galvalume finish direct water away from fascia boards and foundation areas. This detail prevents the moisture problems that plague many Central Texas homes, especially important given our clay-rich soils that expand and contract with seasonal moisture changes.
This project's complexity required extensive custom metalwork. Valley metal channels water flow during heavy rains while counterflashing protects vulnerable wall-to-roof transitions. The home's mixed exterior materials - both stucco and stone - demanded specific flashing profiles to accommodate different thermal expansion rates and surface textures.
Z-bar components along the 1.5" rib profile create weather-tight seals at critical junctions. Plastic caps and specialized caulking systems provide additional protection at penetrations and terminations. Every detail receives attention because metal roofing's longevity depends on proper execution of these seemingly minor components.
Completed in August with final project closure in October, this installation demonstrates metal roofing's advantages in Hill Country conditions. The galvalume finish reflects summer heat, reducing cooling costs during our extended hot season. Impact resistance protects against hail damage that frequently affects this region. Wind uplift resistance exceeds code requirements for the severe thunderstorms common to Central Texas.
The insulation and ventilation systems work together to maintain comfortable interior temperatures while preventing ice damming during occasional winter weather events. Proper drainage through valleys and edge details protects the home's foundation from water damage that could prove costly given our expansive clay soils.
This project illustrates why Hill Country residents increasingly select metal roofing for new construction and replacement applications. Beyond storm protection, metal roofing offers energy efficiency benefits that compound over decades of Texas summers. The material's longevity means fewer replacements compared to traditional shingles that deteriorate rapidly under intense UV exposure and thermal cycling.
Insurance benefits often offset initial investment costs, especially for homes in hail-prone areas like Burnet. The comprehensive approach we took - proper underlayment, insulation, ventilation, and custom flashing - ensures this system will perform reliably regardless of what Central Texas weather delivers.
Austin Pro completed this project through our systematic approach: thorough assessment, proper material selection, skilled installation, and attention to details that ensure long-term performance. For Burnet homeowners considering roofing upgrades, metal systems like this McElroy installation represent smart investments in protection, efficiency, and peace of mind.
