TPO roofing

Energy saving

TPO roofing systems are among the fastest-growing commercial roofing products, especially in recent years as their cost has lowered to be competitive with EPDM systems. This roofing system is constructed out of a combination of polypropylene and ethylene-propylene to create a unique and durable roof. One of the major advantages of TPO roofing products is white coloration which does not have the heat absorption of black rooftops and makes for lower cooling costs.

TPO products come in wide sheets which helps reduce installation costs, compared to EPDM Roofing which has more steps in the installation process. This type of roofing is popular for “green” buildings as it doesn’t contain plasticizers. The durability and overall cost effectiveness of TPO commercial roofing products is excellent and even resists UV radiation damage.

EPDM rubber roofing

The traditional flat roof

The traditional leader among flat commercial roofing products, EPDM is a weatherproof, economical solution to your commercial roofing needs. This type of roofing is constructed of a synthetic rubber compound, making it extremely durable and resistant to UV radiation. EPDM roofing is versatile and long-lasting, even in the harsh Wisconsin elements. While the black coloration of EPDM rubber can lead to higher cooling costs compared to TPO roofing, in Wisconsin the costs are much less than in Southern states.

Fluid Applied Rooofing Systems in Outagamie County

Fluid applied roofing systems

Water and weatherproof

A simple alternative to asphalt & gravel roofing, fluid applied roofing systems create a seamless bond on commercial flat roofs. Fluid applied roofing systems including urethane and polyurea are a popular choice for Wisconsin businesses as the seamless membrane will not crack during cold weather. Sprayed Polyurethane Foam (SPF) insulation is frequently covered using fluid-applied roofing systems such as silicone and acrylic.

Contact Infinity Exteriors and learn how a fluid-applied roofing system can benefit your business.

Bitumen BUR system

Bitumen roof systems

Superior flexibility and impact resistant

Bitumen roofing material is the critical cap of Built-Up-Roof (BUR) systems. Many Fox Valley business owners favor bitumen roofing as it offers comprehensive waterproofing and weather resistance. When installed by a certified roofing contractor, bitumen roofing systems resist cracks caused by cold weather contraction better than asphalt & gravel systems. Bitumen roofing systems are available for BUR, and as standalone SBS modified and APP modified materials.

Contact Appleton's bitumen roof experts at Infinity Exteriors, LLC today.

PVC roofing system in Oshkosh

PVC roofing materials

Low cost, high performance

A flexible roofing solution, PVC roofing membranes ensure commercial flat roofs are protected from all manner of damage. Many flat roofs experience heavy ponding, especially in Wisconsin during the spring thaw. A PVC membrane creates a watertight seal which prevents water penetration and protects the roofing substrate. Once the sun comes out in summer, PVC membranes protect roofs from UV damage.

Contact Infinity Exteriors, LLC today to learn more about commercial PVC roofing membranes.

Commercial flat roof materials and coating

Infinity Exteriors offers only the best materials for flat roofing systems such as GAF, Versico and Mulehide TPO and EPDM rubber roofing products. We provide new installations, repairs, and commercial roof replacements for businesses in Fox Valley. A popular alternative to flat roof replacement is fluid-applied roofing systems that provide completely seamless waterproofing for your roof. Veteran Infinity flat roof contractors can also apply polyurethane-based Neogard roof coating to extend the life of your low-slope roof.

To get the most protection against harsh Fox Valley Wisconsin weather on your flat roof, we install built-up roofing (asphalt & gravel roofing) for long-lasting weather resistance and modified bitumen waterproof membranes on commercial buildings. We also offer PVC single-ply roofing as a low-cost, low-maintenance commercial roofing material.

Advantages of flat roofs

Flat roofs cost less to build than pitched commercial roofs, with less roofing material required and faster, easier installation. Low-slope roofs are easier to walk on and inspect, maintenance is generally more affordable than steep slope upkeep. 

With a flat roof, you’ll also have new usable space on your roof area for air conditioning units, solar panels, along with other equipment. Flat roof systems improve thermal insulation, making them energy efficient and great option for regions with high winds.

Are flat roofs really flat?

No, a “flat roof” is never completely level. Also known as “low-slope roofs” flat roofs always have a very slight pitch, with just enough of a slope to drain water. 

While as a rule of thumb low slope roofs are more prone to leaks and ponding than pitched roofs, but this is only due to poorly installed and improperly maintained roofing. With Infinity Extererior flat roof experts, you won’t have to worry about frequent cracks or leaks.

Common commercial roofing problems

Poor drainage

The basics: Heavy rain and snow on a commercial roof can form puddles which wear away at the roof material. The water then works its way inside, creating a leak.

Why it happens: Many commercial buildings have flat roofing. A perfectly flat surface will not drain naturally after it rains or snows. Standing or ponding water can lead to expensive leaks.

How to prevent it: Professional roofing installation from Infinity Exteriors on a “flat” roof will include low slopes with a very slight pitch to drain water. Other features like flashing materials and gutters will also promote better drainage.

Leaky flashing

The basics: Flashing weatherproof material is used to reinforce roof joints and seams. Leaks around flashing can weaken already vulnerable areas of the roof.

Why it happens: Chimneys, windows, and HVAC systems all create gaps in roofing material requiring flashing. If the flashing is not installed correctly, it won’t keep water out.

How to prevent it: Infinity Exteriors will recommend the right material and style flashing for your roof. will give you an estimate on installing and replacement so you know the costs upfront.

Membrane shrinkage

The basics: Certain roofing materials like PVC or EPDM membranes can shrink under extreme conditions.

Why it happens: DIY roofing projects may mix incompatible materials, leading to a weaker membrane more prone to shrinkage. Poor installation may result in an ill-fitting roof with shrunken sections.

How to prevent it: Professional roof installation will result in a better fit with the right materials, reducing the chances of shrinkage.

Membrane tenting

The basics: The membrane on the roof acts like a giant sheet. Tenting, billowing, or blow-off occurs when the membrane is not firmly attached to the rest of the roof.

Why it happens: Improper installation can cause sections of membrane to separate from the roof. This leads to the loose sections blowing around or filling up with air.

How to prevent it: Expert roof installation and regular maintenance from Infinity Exteriors will keep the membrane material in check.

Interior issues

The basics: A leak in a roof can lead to interior leaks. Water damage in an attic area often indicates an exterior problem.

Why it happens: Ponding water on the roof can leak through to the inside of the building. The moisture can weaken wood and create the perfect environment for mold.

How to prevent it: Pay attention to the interior of your roofing. Any indoor leaks or water stains are likely being caused by a roof issue.

Animal nesting

The basics: Wisconsin winters drive animals to find any warm shelter. Attics and HVAC systems often seem suitable for small animals, providing them interior access to your commercial building.

Why it happens: Birds and animals only need a very small space to enter a building. Minor tears in roofing material are more than enough. Once in, they can wreak havoc on the rest of the roof.

How to prevent it: Reduce the potential entrances animals will create. Have the professionals of Infinity Exteriors fix all holes in your roof material, cover gutters, and watch for membrane shrinkage.

Tree damage

The basics: Trees near your commercial building can fall or lose branches from severe weather or age.

Why it happens: Heavy tree limbs and sharp branches can cause a lot of roof damage. Even a small branch can penetrate a roof in the right conditions. A single tear in the weatherproofing can let water enter the building, leading to more problems.

How to prevent it: Keep trees near your building trimmed or hire a professional to handle you landscaping.

Ice damming

The basics: Melted snow or ice needs to be drained from your commercial roof. Otherwise, the water may refreeze around the flashing or gutter system. This process creates ice dams. Water will build up around the ice. The more weight from ice, the more work your roof has to do.

Why it happens: Poor building insulation heats roof snow and ice from below, causing it to melt while the rest stays solid. 

How to prevent it: Infinity Exteriors contractors will install insulation at your property to prevent the creation of ice dams and save energy. With heat no longer escaping through the roof, your heating system can take a break.

Exposed HVAC

The basics: HVAC systems are usually installed on the roof of commercial buildings to save floor space and provide more efficient heating/cooling services.

Why it happens: The physical components of a commercial-grade HVAC system includes a lot of parts and weight. This adds additional strain to the roof. Repair or maintenance work on the unit can lead to foot traffic damage as well.

How to prevent it: Always have your roof checked out before and after installing a new HVAC unit. Infinity contractors can check to see no part of the roof was damaged during the installation process. 

Foot traffic

The basics: Modern buildings often have HVAC systems, chimneys, and other features located on the roof. People must then walk on the roof to reach these areas.

Why it happens: Regular foot traffic can lead to wear and tear. Certain types of shoes and heavy tools can damage roof material. These scrapes and rips ruin the weatherproofing. 

How to prevent it: Only certain employees should be allowed on the roof for any reason. If anyone has to work on the roof, supervise the work.

Ignoring problems

The basics: Like every part of your business, your roof needs regular maintenance. Ignoring any of these listed issues can lead to further roof damage in the future.

Why it happens: Many commercial properties are leased out, making it difficult to know who should be keeping tabs on maintenance issues.  

How to prevent it: Employees should be trained to notice and report major problems. Hire Infinity Exteriors for regular checks and maintenance.

DIY disaster

The basics: DIY kits for minor roof repairs are available at most major hardware stores. Yet deeper roof issues are easy to miss and difficult to fix with these kits.

Why it happens: DIY kits are mass-produced and usually meant to create temporary fixes. Sometimes the results don’t work at all. In worst case scenarios, inexperienced workers can injure themselves while on the roof.

How to prevent it: Call in the professionals of Infinity Exteriors whenever you need work done on your roofing. Not only are the results more reliable, it’s safer for your workers.
