As beautiful as it is long-lasting, an EDA slate roof adds dignity and value to any building structure.

Types of Slate & Copper Roofing

Chimney Restoration

When beauty and historic integrity in your chimneys are as important to you as are their functional attributes, then a restoration is the best choice. Using the best materials and old-world copper and masonry techniques, we will rebuild a chimney to its original stately condition.


Owner/Operator Mike Bregenzer has over 20 years experience at installing new and renovating slate roofs. Mike has assisted many building owners and their architects in designing custom systems to maximize their roof's effectiveness and integrity.

Copper Gutters

We custom fabricate copper gutters that need almost no maintenance and grow more beautiful as the years pass. Combining modern techniques and attention to detail, the firm's gutters are artistic and functional accents which will highlight the elegance and stateliness of any home or building.

Copper Leader Heads

An integral part of any roofing/drainage project, leader heads must be solid, functional and care-free. From simple initials, a commemorative relief or coat of arms, to just about any image sculpted in relief, a hand-made Bregenzer Brothers copper leader head is unmistakable.

Copper Roofing

Whether hand-formed or utilizing modern computer-guided shaping tools the firm is able to complete any job, from the smallest and most detailed to the largest and most technically demanding, on time and under budget.

Custom Copper Work

Whether a complementary detail to a larger project, structural underpinning, or comprehensive custom-cut, sculpturally molded and seamlessly joined roof or other large scale sheathing, the Bregenzers can execute a multitude of projects to clients' exact specifications.

Maintenance & Repair

Slate and copper roofs ideally can last for many generations, but must be regularly inspected and maintained to retain their full seal, strength and beauty. We offer annual and semi-annual maintenance programs to help facility managers maintain the integrity of their roofs.

New Slate Roofs

EDA will cut and install new construction slate roofs to the exact specifications of our customers. Using an extensive network of quarries sourcing slate of a variety of different hues and characteristics, we will then cut the slate and create roofs of any style and pattern.

Slate Roof Restoration

With a knowledge of slate roof engineering going back generations, the Bregenzer Brothers have the expertise to analyze older slate roofs and restore them to "as new" condition, using carefully matched materials and original techniques.

Thru Wall Flashing

Thru wall flashing is an important component in exterior building systems, critical to protect wall assemblies and foundations from water and moisture build-up. Bregenzer Brothers works together with other trades to fabricate and install thru wall flashing for intelligent water management.

Zinc/Tin Coated Copper Roofing

Zinc/tin coated copper roofs are a non-corrosive, environmentally friendly product with a 100% clear water runoff. Zinc is a natural material that never fades and retains its look over its entire life span. Zinc roofs and walls have a long service life with an expected service life of 60-100 years.
