Built-up asphalt and coal-tar bituminous roof systems are the tried-and-true historic standards in low-slope roof applications. Multiple plies, or layers, are applied with hot bitumen to achieve a highly durable roof assembly. Coal tar and asphalt are heated in a kettle. Then they are applied via mop or mechanical spreader. Asphalt roof systems are highly durable, and coal-tar pitch systems are somewhat self-healing in nature due to their low melting point.
Kalkreuth Roofing can assist in determining the type of built-up system best suited for your situation. We can also install both self-adhered and fully adhered vapor barriers under any of our roofing systems.
Built-up roofing systems are available in various thicknesses, finishes and number of plies. The top layer is often gravel surfaced or may be smooth with a liquid coating. Most built-up systems are relatively easy to repair with common cement. Warranties are available from 10 to 20 years.
FEATURES
- Highly durable – multiple plies/layers of material in hot bitumen which is water resistant
- Wide variety of standard finish textures and colors of gravel
- Can be phased on new-construction projects so that the top layer is the final stage
- Coal-tar bituminous roofs are able to withstand ponding water
OPTIONS
- Asphalt or Coal-tar
- Various thicknesses and strengths of plies
- Gravel or smooth finish
- Multiple color options depending on type of finish

Standing seam metal roofing is fabricated from flat metal material that is roll-formed with a flat horizontal pan and vertical ribs on each side. The flat pan is typically from 12” to 18” wide and the ribs are most often 1” to 3” high. The panels can be made in various profiles for increased stiffness or aesthetic appearance. The seams are made watertight by “locking” or folding over the tops of the vertical ribs, and the top of the standing seam is held above the pan so that running water will not flood into the seam. The panels are held in place by clips which are located inside of the seam. Panels can be made from a wide selection of metal materials and either natural or painted finish, depending on the type of metal.
FEATURES
- Designed for relatively little chance of water filtration so long as there is proper slope and flashing
- Very few exposed fasteners
- Vertical ribs for strength and aesthetic appeal
Can attach claps to the seams to mount items such as snow rails, solar panels and walkways
OPTIONS
- Variety of metal materials such as galvanized or galvalume steel, aluminum, zinc, copper, and terne
- Numerous finishes such as natural, patina, painted, or pre-weathered
- Many size options available in various widths, lengths and profiles
Flat seam panel construction is typically found on historic structures where quality vintage craftsmanship was used. Pieces of metal are fabricated with relatively flat joints in varying sizes; most often small enough to be easily handled. Materials most likely used were copper or lead-coated metal, and the seams were soldered together on the roof. These materials can still be fabricated and installed using the same process and soldered together; although, new modern panel profiles made from galvanized steel and aluminum are on the market. The new style of galvanized steel or aluminum flat seam panel is not soldered but typically installed as a rainscreen-type assembly with a painted finish.
FEATURES
- Most-often found using high-quality natural materials which are soldered together with the utmost in fine craftsmanship
- Natural materials most often have an organic finish that will patina and change as it weathers
- Soldering ensures complete watertightness in the panel seam
- Modern painted flat seam panels are economically constructed as a rainscreen-type assembly
OPTIONS
- Soldered seams or snapped-together rainscreen assemblies
- Choice of metal materials and finishes
Modified roofing systems come in various options for material thicknesses, finishes and number of plies. It can be cold-applied, installed with hot asphalt, or heat-welded with propane flame. The top layer is called the “Cap Sheet” and can be covered with granules or gravel, or be smooth with a liquid coating. This allows for a wide selection of finished colors, especially when acrylic coatings are applied. Modified systems are often found on hospitals, automotive plants, data centers and universities.
Kalkreuth Roofing can assist in determining the type of modified system best suited for your situation. We can also install both self-adhered and fully-adhered vapor barriers under any of our roofing systems.
Modified bituminous roofing systems could be considered the “modern” version of the old tried-and-true asphalt built-up systems. Multiple plies, or layers, are applied with adhesives to achieve a highly durable roof assembly. Typically asphalt based, modified systems may also be based on coal-tar composition. The most popular systems are SBS and APP, which consist of asphalt and other chemicals combined for flexibility and durability. Warranties are available from 10 to 30 years.
FEATURES
- Highly Durable – multiple plies/layers of material in adhesives
- Wide variety of standard finish textures and colors
- Can be phased on new-construction projects so that the top layer is the final stage
OPTIONS
- Various thicknesses and strengths of plies
- Granules, gravel or smooth finish
- Multiple color options depending on type of finish
Single ply is a class of roofing membrane that is made of flexible synthetic materials manufactured in a highly controlled process. The consistency of quality, product strength, flexibility and durability, along with multiple methods of attachment, make single ply roofing a viable choice in a variety of applications.
The type of single ply roofing right for a particular job is dependent on several factors including the height of the building, wind exposure, foot traffic, desired look and cost. How the roof is attached to the roof deck is also dependent upon the application and can include mechanical fasteners, ballast, or adhesive.
Kalkreuth Roofing can assist in determining the type of single ply system suited best for your situation. We can also install both self-adhered and fully adhered vapor barriers under any of our roofing systems.
EPDM roofs are made from synthetic “rubber” material in either black or white-on-black colors. Membranes are available either with or without internal scrim reinforcement, for durability and strength, and in thicknesses of .045” to 0.90”. EPDM roofs are installed by full adhesion, attached mechanically or secured with ballasts. Seams are secured with butyl-tape technology. Warranties on this type of roof system are available from 10 to 30 years.

PVC/ KEE roofing systems are single-ply membranes with a plasticized formulation. Each type of membrane has a proprietary chemical mix which gives it unique properties, though all PVC/KEE membranes are scrim reinforced. PVC membranes are based on a polyvinyl chloride chemical composition with additional chemicals which keep the membrane flexible and protect from UV degradation. KEE membranes utilize DuPont Elvaloy to protect against UV damage. Seams are heat-welded, much like TPO. Modern PVC/KEE membranes are often characterized as a premium single-ply method to achieve solar-reflectivity and LEED/Energy-Star compliance. Color options are much the same as TPO, but manufacturers typically offer even more custom options in PVC and KEE formulations. Thicknesses range from 0.36” to 0.80” and warranties are available up to 20 years.
FEATURES
- Typically grease-resistant (ideal for restaurants)
- UV stable – considered more durable than TPO when exposed to concentrated sunlight
