Roofing & Sheetmetal

Liquid-applied membrane roofing systems provide seamless, fully adhered waterproofing for low-slope roofs and complex geometries. EDA installs cold-applied and reinforced liquid membrane systems that conform to irregular substrates, penetrations, and transitions. These systems create a monolithic barrier that reduces leak risk while offering flexibility, durability, and ease of detailing in challenging roof conditions.

EDA installs single-ply membrane roofing systems, including EPDM, TPO, and PVC, for low-slope commercial and institutional applications. These systems offer proven resistance to weather exposure, flexibility, and energy efficiency when properly detailed. Our approach emphasizes careful treatment of penetrations, terminations, and perimeter conditions to maintain continuity across the roof assembly.

Modified bitumen roofing provides a robust, multi-layer solution for low-slope roof systems. EDA installs both torch-applied and adhesive-applied assemblies, selected to suit project safety requirements and substrate conditions. These systems deliver dependable waterproofing performance and added redundancy in demanding environments.

Hot-applied rubberized asphalt membrane systems create a fully adhered, seamless waterproofing layer with exceptional durability. The membrane bonds directly to the substrate, preventing lateral water migration. This system is commonly used in plaza decks and terraces with complex detailing and overburden requirements.

EDA installs steep-slope roofing systems that support architectural design while providing reliable water-shedding performance. Our experience includes asphalt shingles, slate, and cedar roofing, integrated with appropriate underlayments, flashings, and ventilation components. Attention to detail ensures lasting performance and a refined finished appearance.

Standing seam metal roofing systems offer long service life, low maintenance, and clean architectural lines. EDA installs concealed-fastener panel systems engineered to accommodate thermal movement while maintaining weather tightness. These systems are frequently selected for their durability, performance, and visual consistency.

EDA fabricates and installs custom sheet metal and through-wall flashing systems that manage moisture within wall assemblies. Using materials such as copper and stainless steel, our flashings are designed to collect and direct water out of the building envelope. Coordination with adjacent trades ensures continuity and long-term performance.
