Our Flat Roofing Systems

We offer a range of flat roofing systems designed to meet different needs. Each system provides durability, weather resistance, and energy efficiency, ensuring your flat roof performs well over time.

Single-Ply Membrane Roofing

Single-ply membrane roofs are made from flexible sheets, usually TPO, PVC, or EPDM materials. These membranes are popular for their ease of installation and ability to resist UV rays, chemicals, and weather damage.



They come in large sheets that reduce seams, lowering the chance of leaks. If you want a low-maintenance option with good energy efficiency, TPO and PVC offer reflective properties that help keep your building cooler.


EPDM is valued for its durability and flexibility, especially in colder climates. We install all these membranes with attention to detail to ensure proper sealing and longevity.

Built-Up Roofing Systems

Built-up roofing (BUR) is one of the oldest flat roofing methods. It uses multiple layers of bitumen and reinforcing fabrics, such as fiberglass or felt, topped with a protective surface like gravel or a coating.



BUR provides strong, long-lasting protection against water and foot traffic. The multiple layers create a thick, waterproof barrier that performs well in harsh weather.


If you want a roofing system known for toughness and proven reliability, built-up roofing is a solid choice. We apply each layer carefully to ensure maximum coverage and durability.

Modified Bitumen Solutions

Modified bitumen roofs combine asphalt with modifiers like APP or SBS to boost flexibility and strength. These systems are rolled out in sheets and can be heat-welded or adhered with cold adhesives.


They work well for buildings that need extra resistance to temperature changes and physical wear. Modified bitumen offers good waterproofing and can be layered to add thickness.


If you expect heavy use on your roof or live in an area with extreme weather, this solution might be the best fit. We make sure seams and edges are secure to prevent leaks.

Green and Reflective Roofing Choices

Green roofing adds vegetation layers over a waterproof membrane, providing insulation and reducing stormwater runoff. Reflective roofing uses light-colored materials to reflect sunlight and reduce heat absorption.



Both options help improve your building’s energy efficiency and lower utility costs. Green roofs also promote sustainability and can extend roof life by protecting the membrane from sun damage.


If you want to decrease your building’s environmental impact or manage heat better, these options are worth considering. We install these systems to meet environmental standards and your performance needs.

Installation Process

We ensure every step of your flat roof installation is done carefully and with attention to detail. From the first visit to getting the site ready, we focus on clear communication and thorough work to protect your property and meet your needs.

1. Initial Consultation and Assessment

We visit your property to check the roof’s condition. We look for any damage, measure the area, and note details like roof slope and drainage. This helps us understand what materials and methods will work best for your flat roof. We also discuss your goals and budget. This way, you know what to expect, and we can tailor the project to fit your needs. If needed, we identify any repairs before the installation begins.

2. Project Planning and Proposal

After the assessment, we create a detailed plan. This includes choosing the right insulation, membrane type, and other materials for your roof. We provide a clear written proposal that outlines the scope, timeline, and costs. You'll see exactly what is involved and when the work will start and finish. Our plan also considers weather and any permits needed to avoid delays.

3. Preparation and Site Safety

Before work starts, we protect your property and neighbors by setting up barriers and safety signs. We remove any debris or loose materials from the roof to make sure the surface is clean. Our team follows strict safety rules. We use harnesses, scaffolding, and other equipment to keep everyone safe during the installation. This preparation helps the job go smoothly and prevents accidents on-site.

Flat Roof Installation Methods

When installing flat roofs, there are several ways to secure the roofing materials to ensure durability, weather resistance, and energy efficiency. Each method has its benefits depending on your building type, budget, and local climate.

Adhesive Application Techniques

Adhesive application is a popular method for installing flat roofing membranes. We apply a strong roofing adhesive evenly across the roof deck, then carefully lay the membrane onto the glued surface. This method creates a seamless bond that prevents water infiltration.


Using adhesives reduces the need for mechanical fasteners, creating a smooth, clean roof surface. It also helps with energy efficiency by limiting air pockets under the membrane. Proper surface preparation is crucial to ensure the adhesive bonds well. We make sure your roof deck is clean, dry, and primed before application. This technique works best on flat or low-slope roofs with complex shapes where mechanical fastening is difficult.

Mechanically Fastened Systems

With mechanically fastened systems, we use screws, plates, or fasteners to secure the roofing membrane directly to your roof deck. This method is reliable for roofs that experience heavy wind uplift or if the roof substrate can handle penetrations without damage.



We space fasteners evenly across the roof, focusing on edges and seams to provide maximum holding power. One advantage is that it often costs less than fully adhered systems, and repairs or replacements become easier since the membrane isn’t glued down. This system fits well with metal or wood decks where you require a secure attachment but want a faster installation process.

Heat-Welded Seams

Heat-welding is the process of joining roofing membranes by melting their edges together to create a watertight seal. We use specialized hot-air tools to fuse synthetic materials like TPO or PVC.



This method makes seams strong and resistant to leaks over time. It is ideal for commercial flat roofs where long-term durability is a priority. Heat-welded seams hold up well against harsh weather, offering tight connections between membrane sheets.


Proper welding technique requires skill and experience to avoid weak spots. We ensure quality control by inspecting every seam for consistent bonding and proper fusion throughout installation.

Quality Assurance and Safety Standard

We prioritize high standards and strict safety measures to ensure your flat roof installation lasts and performs well. Attention to detail and professional oversight are key to delivering quality results that meet all regulations and your expectations.

Certified Roofing Professionals

Our team consists of certified roofing professionals who have experience with flat roof systems such as TPO, EPDM, and PVC. These certifications mean our roofers follow industry best practices and stay updated with new materials and techniques.



Each technician undergoes regular training to maintain certifications and improve skills. This helps us prevent common installation issues and avoid costly repairs later. Using certified professionals also ensures proper handling of materials for durability and weather resistance specific to Wisconsin’s climate.


We treat craftsmanship seriously, ensuring every step meets manufacturer requirements and local building codes. This focus provides you with peace of mind, knowing your roof is installed by experts who understand the unique challenges of commercial flat roofing.

On-Site Inspections and Compliance

Before and during installation, we perform thorough on-site inspections to check for any structural concerns or obstacles. These inspections help us tailor the roofing process to your building’s specific needs, reducing risks of future leaks or damage.



Throughout the project, our supervisors monitor compliance with safety protocols and building regulations. This means we follow OSHA guidelines and use proper safety gear, minimizing hazards for both workers and your property.


After installation, we conduct final inspections to confirm everything is secure and up to code. We review seams, drainage, and insulation to ensure long-term performance. Documentation is provided for your records, helping with warranties and future maintenance..
