Our Services


New Construction Roofing (Commercial)

Jottan-Jorel Inc. has a long history working with General Contractors and Construction Managers on a wide variety of new construction projects. We understand the complexities that arise during project execution and have the ability to adapt to the needs of a "fast-track" project to ensure the structure becomes water tight in the shortest amount of time.


At some point during the life of a roof, the need for a retrofit or a complete replacement arises. When your roof has been damaged, needs to be fixed or has reached the end of its serviceable life, a re-roofing option may be necessary.

Although it is appealing to continually do repairs on a failing roof as repairs require less labor, material and time (i.e. cost), it is important to understand that there is a point in time where simply doing repairs vs. replacement/retrofit can be causing more harm than good. At that time it is important to select the right contractor to honestly assess the condition of the existing roofing system and provide the best possible short and long term roofing strategies that can include both repair and re-roofing options.

Jottan-Jorel has over 30 years experience in Reroofing involving most commercially roofing systems on a wide variety of structures. We understand the need to minimize disruption during the project and will work with the appropriate personnel to ensure a “smooth” installation.

Single Ply Roofing– EPDM

Single Ply – EPDM (Ethylene Propylene Diene Monomer), sometimes referred to as ‘rubber’, is a thermoset membrane material. Its flexibility and ability to be installed in most climates makes EPDM one of the most popular choices in today’s low slope commercial roofing market.

EPDM membranes can be installed either with adhesives (fully adhered), mechanically attached with plates and screws or loose laid with ballast. EPDM membranes can be repaired easily and although most commonly is installed as black, can also be available in white.

Jottan-Jorel Inc. uses trusted brands such as Firestone, Carlisle, Versico, and JM when considering EDPM for your roofing needs.

Single Ply Roofing- Thermo Plastics

Thermoplastic Single-Ply systems (TPO and PVC) are among the fastest growing roofing systems today. Similar to EPDM, Thermoplastic systems can be used in many different applications. TPO and PVC roofing systems combine the durability of EPDM membranes with the performance of a heat welded roofing system (meaning the seams are ‘melted’ or welded together).

Most TPO or PVC systems are installed as white taking advantage of the inherent reflective properties however; most manufacturers can customize the color of membrane including popular options such as gray, tan or black.

Jottan-Jorel Inc. uses trusted brands such as Carlisle, Firestone, JM, Versico, Dow and GAF when considering Thermoplastics for your roofing needs.

Metal Roofing

An alternative to traditional roofing is using a metal roofing system. Although the initial investment is higher compared to a traditional roofing system, metal systems have been shown to last 2-3 times as long compared to those traditional systems which typically last anywhere from 10 to 20 years.

Another benefit to metal roofing systems is the flexibility on colors and designs. Metal roofing systems can come in the form of Standing Seam or can be made to look like Asphalt Shingles, Tiles or Cedar Shakes.

Although Metal Roofing Systems can come in the form of Copper and Stainless Steel, the most popular choices are Aluminum and Steel.

Jottan-Jorel Inc. use trusted brands such as Unaclad, Berridge, Atas, AEP Span and McElroy Metal when considering Metal materials for your roofing needs.

Spray Foam Roofing

Spray foam roofing begins as two different components are mixed at a one-to-one ratio a chemical reaction occurs and the mixture expands 20 to 30 times and then forms a solid, monolithic, closed-cell, fully-adhered roof system that is highly water resistant and provides excellent insulation.

It adheres to most surfaces including concrete, wood, steel, and most existing roof systems. This can help you save several different costs including roof removal. Also we often can make a tapered roof system with the SPF eliminating the need for costly insulation systems and helps to minimize any additional component costs.

The mixture is sprayed in passes that are half an inch to one inch thick resulting in a roofing system that expands to several inches thick. SPF roofs are not soft. They are very durable and can handle foot traffic and have a relatively long lifestyle when they are maintained every 10 to 15 years.

Jottan-Jorel uses trusted brands such as E.R. Systems and Bayer when considering Spray Foam as a possibility in your roofing project.

Built-Up Roofing (BUR)

Built-Up Roofing Systems or B.U.R. systems have been used in the United States for over 100 years. It is designed for low sloping or flat roofs. They are usually made of alternation layers of reinforcing fabrics called roofing felts or ply sheets that create a finished “crust” and are sometimes referred to as tar and gravel roofs. They are built up by alternating layers of asphalt or coal tar saturated felts or fiberglass mat roofing sheets. They can have differing amounts of layers called plies and are considered fully applied when positioned directly on the roof’s deck or insulation.

The asphalt or coal tar is heated in a kettle or tanker and then applied by mop or spreader. Surfacings for BUR systems include aggregates like gravel, slag, or mineral granules, glass fiber, or mineral surface cap sheets, hot asphalt mopped over the entire surface, or aluminum coatings.

Built-Up Roofing Systems can be very durable and have a long life span if they are carefully installed, with multiple layers, and with quality bitumen, felts, and flashings. It can be used in both new and existing construction projects and building. They have very little flexibility and should only be used on roof decks that have minimal movement. BUR systems do need occasional maintenance to extend their service life.

Jottan-Jorel uses trusted brands such as Johns Manville, GAF, and Tremco when considering Built-Up Roofing Systems as a possibility in your roofing project.

Modified Bitumen Roofing

Modified Bitumen, commonly referred to as Mod-Bit, is another asphalt based system is similar to B.U.R. Systems. Mod-Bit has been successfully used in North America since the 1970s and is made to have less brittleness in cold temperature, greater flow resistance in warmer temperatures, more elasticity than comparable B.U.R. systems, greater strength, quality assurance of membrane production consistency and control, and reduced labor for installation. There are different surfacing options including reflective coatings to cut cooling costs, color options to compliment building designs, existing shingles, or the standard white granules.

Mod-Bit Systems can be applied in four ways: Torch Applied, Hot-Mopped, Cold Applied, or with Self-Adhesives (Peel and Stick).

Jottan-Jorel uses trusted brands such as Viridian, Firestone, Johns Manville, Garland and GAF when considering Built-Up Roofing Systems as a possibility in your roofing project.
