Doliveira Systems LLC is a general contractor certified in every major roofing system used in the Mid-Atlantic region, from single-ply membranes to steep slope and metal. Our crews bring more than 50 years of combined field experience to each project, and UL and FM approved assemblies are available across our systems.
Single-Ply
Lightweight, synthetic elastomer used since the early 1970s. EPDM's resilience, tensile strength, and resistance to ozone, UV light, and ponding water make it an outstanding roofing material.
Single-Ply
Lightweight, reinforced, light-colored membrane used since the early 1970s. Highly resistant to chemical atmospheres, ozone, UV light, tears, and extreme weather conditions.
Retrofit
With a variety of attachment methods, our Metal Retrofit System can be configured to most metal roof designs and meets national, state, and local building codes.
Coating
A special formulation of non-toxic, water-based acrylics that cures into a continuous elastomeric membrane. Provides an excellent restoration solution for metal roofs.
Coating
Materials for roof surfacing, maintenance or repair to enhance weatherability, reflectivity, UV protection, or aesthetics of the installed roof system.
Built-Up
Multiple layers of felts, fabrics or mats saturated with bitumen, installed in alternating solid mopping of hot bitumen or cold adhesives.
Bitumen
Polymer modified bitumen sheet membranes (SBS and APP) have been used since 1975, composed of asphalt reinforced with polyester or fiberglass.
Spray Foam
SPF roofing has been used for over 35 years. No matter the physical shape of the roof, this seamless system can be effectively applied.
Steep Slope
Comprehensive range of steep slope solutions for diverse aesthetic and functional requirements across commercial applications.
Metal
Concealed panel system provides versatility, durability, and aesthetic appeal for both industrial and architectural applications.
