Our Installation Process

We focus on understanding your building’s needs, then create a clear plan and prepare everything carefully. Every step is designed to ensure the roof fits well and works properly.

Consultation and Assessment

We start by visiting your property to check the current roof condition and building structure. This helps us find any damage or special needs that the new flat roof must address.


Our team measures your roof area precisely and inspects drainage systems. We also discuss materials, budget, and your goals to make sure we meet your expectations.


This detailed check helps avoid problems during installation and ensures the roof will last. We answer any questions and explain what to expect during the process.

Custom Design and Planning

Once we know the details, we design a roof system tailored to your building. We pick materials based on durability, weather resistance, and energy efficiency.


Our plan includes the layout, drainage solutions, insulation, and membrane type. We use clear drawings and timelines so you can see exactly how the work will go.


We also schedule inspections and get any necessary permits. Planning carefully helps avoid delays and keeps everything on track.




Scheduling and Preparation

Before work starts, we set a schedule that fits your availability and weather conditions. We confirm the timeline with you and prepare the site for safe, clean installation.


Our crew brings all tools and materials to the site. We protect your property by using tarps and cleaning up daily.


Our organized approach reduces risks and keeps the project running smoothly until your new flat roof is complete.

Roofing Material Selection

Choosing the right roofing material affects the roof’s durability, maintenance, and energy efficiency. We focus on options that fit different budgets and building needs while ensuring long-term performance.

Single-Ply Membranes

Single-ply membranes are popular for flat roofs due to their flexibility and ease of installation. We use three main types: TPO, EPDM, and PVC.


TPO (Thermoplastic Olefin) offers good heat reflection and resistance to UV rays. It is energy-efficient and prevents mold growth. TPO membranes are also weldable, creating strong seams.


EPDM (Ethylene Propylene Diene Monomer) is a rubber membrane known for durability and weather resistance. It works well in extreme temperatures and is cost-effective.


PVC (Polyvinyl Chloride) is a plastic membrane that provides excellent chemical resistance and fire retardancy. It is durable but usually costs more than EPDM or TPO.

Built-Up Roofing Systems

Built-up roofing (BUR) uses multiple layers of bitumen and reinforcing fabrics. It creates a thick, water-resistant surface on flat roofs.


We install between three to five layers, which helps with durability and leak protection. These layers are topped with gravel or a reflective coating to shield from sun damage.


This system offers strong waterproofing and long life but is heavier than single-ply options. It requires careful installation to prevent ponding water.

Modified Bitumen Solutions

Modified bitumen is an evolution of built-up roofing with added polymers for flexibility and durability. We often use APP (Atactic Polypropylene) or SBS (Styrene-Butadiene-Styrene) modifiers.


APP-modified bitumen resists heat and UV rays, making it ideal for hot climates. SBS offers better elasticity and toughness, especially in cold weather.


This roofing type is usually applied with heat or self-adhesive sheets. It combines strength with ease of repair and is suitable for both new roofs and overlays.

Why Flat Roofs Are Ideal for Commercial Properties

Flat roofs offer several benefits that directly impact cost, space, and upkeep. Their design supports better energy control, adds useful space, and makes repairs simpler and quicker.


Energy Efficiency and Insulation


Flat roofs allow us to install thick layers of insulation with fewer gaps. This helps keep buildings cooler in the summer and warmer in the winter. It reduces the need for extra heating or cooling, lowering energy bills. We can easily add reflective coatings or energy-saving membranes on flat roofs. These materials reflect sunlight and reduce heat absorption. This keeps the building temperature stable and saves money on air conditioning.


Using energy-efficient materials on flat roofs also contributes to meeting green building standards. This is important for companies aiming to reduce their environmental impact.


Maximized Usable Space


Flat roofs provide extra space that we can use for many purposes. Businesses often convert this area into rooftop gardens, seating, or solar panel installations. This added space can boost property value and improve the work environment without expanding the building footprint. It is especially valuable in crowded urban settings where land is limited.


Our clients appreciate that flat roofs give them options to customize the space for their needs. This flexibility makes flat roofs a smart choice for commercial properties.


Ease of Maintenance


We find flat roofs easier to inspect and repair because of their simple, flat surface. Walking on a flat roof is safer and less likely to cause damage compared to sloped roofs. Repairs can be faster and less expensive. We can spot leaks or wear quickly and fix them before they cause serious problems.


Flat roofs also have fewer joints and seams, which lowers the chance of water leaks. Regular maintenance on these roofs is straightforward and helps extend their life.
