Commercial Roofing Systems

Each commercial roofing system has its best uses, strengths, and benefits. Our commercial roofing consultants are knowledgeable about all and will help you choose the best option for your building.

Types of commercial roofing systems we install:

Asphalt Built-up roofing is the oldest means of roofing applications providing water tight integrity to your building envelope.

Asphalt BUR originated in the construction market around the 1880’s.  Asphalt and gravel roofs come in a multi ply roof felt application interplyed between hot bitumen. These type roofs remain very durable throughout their life expectancy. Today they have fiberglass felts for tensile strength and are among the favorite with roof consultants based on the history of performance characteristics. Due to the installed cost of material and labor,  BUR has seen its market share dwindling over the last 20 years.

Coal Tar Pitch built up roofing systems was the mainstay product of all roofing solutions of the early 20th century. Known for self-healing properties the roof in the warm summer months flows and self-heals itself where a hole, crack or split appears. Today it is not uncommon to find a roof assembly that is 50 to 60 years old still functioning. These roofs apply multi ply roofing felts with slag gravel on top of the roof. This is one roof that can actually be dead level and hold ponding water as well as hold up year after year providing water tight integrity. With the proliferation of modified bitumen and single ply sheets, Coal tar has been losing market penetration. Koppers and Allied Signal where the two purveyors of the coal tar revolution and both companies have closed their doors. Today the product is still available but due to the cost of material, labor for installation and product availability, coal tar has limited installing contractors and stocking distributors resulting in very few roofing contractors still offering this true and tried unique product.

APP - Plastic Formulated base polymer technology - This roll roofing product comes available in a smooth or granular roof surface in various thicknesses. It may have a polyester or glass or combination of both for the reinforcement depending on performance requirements . It is installed predominantly by heat welding, torching or cold process adhesive applications.

SBS - Synthetic Rubber base polymer technology - This roll roofing product yields superior flexibility to APP in extremely cold outside ambient temperatures. It has options like APP for the reinforcement depending on design criteria. SBS membranes are installed in hot asphalt, cold adhesive or heat welded depending on design criteria.

EPDM single ply came into prominence in the early 1980’s offering building owners an option to Bur asphalt and gravel roofs. EPDM known as ethylene, propylene diene monomer is available in sheets to 50’ wide by 100’ long. The sheet is most flexible in a loose-laid ballasted roofing application. Sheets are available in a thickness to 90 mil in black or white. The membrane can come in reinforced or non-reinforced sheets depending on the method of application. Predominately most applications today are fully adhered applications for high wind uplift and fire retardancy. Warranties are available from the manufacturer to licensed/certified contractors to  30 years covering workmanship and material.

PVC  Membrane- Proven, time-tested commercial roofing material. Seams are heat welded for lasting performance. The reinforced membrane offers excellent puncture and chemical resistance. White PVC is highly reflective, which reduces roof surface temperatures and helps lower energy costs. Most PVC membranes are attached using fasteners and plates, but at times, fully adhered PVC roofing systems using adhesives are the best choice. PVC is a recyclable building material. Warranties are offered by the manufacturer to 25 years.

PVC Prefabricated - The prefabricated roof system is manufactured under ideal factory controlled conditions eliminating up to 85% of the field fabricated seams required by all other roofing systems. This process helps speed installation and eliminates leaks due to field crews working under changing outdoor weather conditions.  Overhead is licensed/certified by Durolast Roofing systems.

TPO Membrane – Its lower initial cost makes this an appealing commercial roofing product.  A reflective white TPO roof means cooler roof surface temperatures and lower energy costs. TPO also provides superior performance against heat aging and UV degradation. TPO roof seams are heat welded for long-term performance and are installed using either mechanically fastened or fully adhered installation. This solution exceeds all key ASTM standards for TPO membranes. Membranes are available to 80 mil thicknesses and warranties are available to 30 years by the manufacturer.

This roofing system provides a durable, energy-efficient re-roofing solution for buildings with metal roofs. It is a cost-effective, maintenance-free solution that protects older metal buildings against rain, temperature changes, interior drips, ice build-up, and rust and corrosion. Warranties vary depending on application.

Standing seam metal roofing systems can be divided into two basic categories: structural and architectural.  Both roof systems can be installed over a large variety of substrates. Architectural roof panel systems are intended for use on steep slope applications, generally 3:12 or greater. Architectural metal roof systems require a solid substrate to support the panels. Architectural panels can either be mechanically seamed or “snapped together,” depending on the panel’s design.

Structural metal roof systems are designed to span across open purlins and can carry snow and wind loads without a solid deck. They can be installed on roof slopes as low as 1/4:12, or on steeper slopes, and even as vertical wall panels.

With seams raised above the roofing panel, standing seam sheet metal roofing systems help provide added protection against moisture. This energy-efficient system combines a modern look with plenty of options to meet different specifications.

Commercial roofing shingles are engineered to deliver excellent protection, durability, and performance at a cost-effective price point. They may be asphalt, metal, synthetic material or concrete depending on application requirement. Warranties vary by manufacturer.

We offer several excellent roof coating systems and can recommend the best one for your application. Options include membrane, elastomeric, surface seal, ER Systems, JM Systems, and others.

Roof Coatings – Elastomeric Roof Coatings can be a good solution for protecting and extending the life of an existing flat, low-slope or metal roof system. They are cost effective, efficient, and easy to install.

Roof Coatings – Elastomeric Acrylic Coating

This coating is a flexible water-based acrylic resin based coating fortified with titanium pigment and non-asbestos mineral extenders. The coating is great for application on old pre-engineered buildings like American and Butler buildings. Often due to aging the building's metal roof begins to leak at screw heads, roof penetrations as well as horizontal and vertical seams. The acrylic coating is most often sprayed in a two coat application and polyester reinforcement is used in conjunction with the coating around roof penetrations and seams providing additional protection. Warranties are available from the coating manufacturer. Warranties are available to 15 years for workmanship and material by manufacturer and specification guidelines.

Roof Coatings – Elastomeric Silicone Coating

This coating has become most prevalent within the last five years due to aging single ply roof membranes. 100% silicone comes solvent-free and can be applied a cleaned single ply membrane after the application of a primer coat in most cases. Silicone creates a glossy, durable, seamless membrane coating that seals and protects against permanent ponding water and ultraviolet light degradation providing watertight integrity to the aging single ply. Warranties vary depending on the manufacturer. Warranties vary up to 20 years depending on application and manufacturer guidelines.
