Commercial Roofing Services

If your office or other commercial space needs a new roof or has some repairs that need completed, call Sun Roofing in Appleton, WI for help!

Sun Roofing offers re-roofing, restoration, and repair solutions for commercial roofing projects of any size. Although re-roofing may seem straightforward, a large commercial roof replacement often represents a significant financial burden. Thankfully, not every stubborn leak warrants a complete roof replacement!

Our proposal process begins with a thorough analysis of your existing roofing system. Infrared Thermography (IR) is the most common technique used to identify potential leaks within the existing roof, although other techniques may be used if necessary.

Once a thorough map of potential trouble spots has been created, core samples will be taken to determine the amount of water retained by the insulation and possibly the substrate. This information will then be incorporated into our proposal to help you select the right roofing system for your unique circumstances with confidence.

Whether you need a half-dozen replacement steel panels, a single-ply overlay, or a brand new seamless rubber membrane, we have the products and expertise to get the commercial roofing job done – on time, and on budget. Throughout your project, our consultants will also work with you to develop a cost-effective maintenance program to maximize the service life of your roofing system, and plan effectively for its continued repair and eventual replacement. Please call our experts today, and let us help you find the roofing system for you.

Flat and Low-Slope Commercial Roofing Options

Sun Roofing offers many options for your flat and low-slope roofing needs, including:

Sun Roofing is proud to offer the TRITOflex™ liquid rubber membrane for roofing and waterproofing projects. TRITOflex™ is a water-based and environmentally-friendly product that sets instantly and can be applied to any thickness on almost any substrate. TRITOflex™ is tough and extremely flexible, withstands ponding water indefinitely, and can also be warranted against baseball-sized hail!

For roofing applications, we recommend the monolithic TRITOflex™ membrane be protected by the TRITOtherm™ insulating coating system. TRITOtherm™ is an acrylic compound with embedded ceramic micro-spheres that is designed to decrease heat transfer and prevent the premature degradation of the underlying membrane. TRITOtherm™ is a white product, but can also be colored to suit specific project requirements.

Single-ply roofing systems can be fully-adhered, mechanically-fastened, or loose-laid and then ballasted using rounded gravel or concrete roof pavers. Three of the most common types of single-ply membrane are EPDM, PVC, and TPO.

EPDM is a thermoset membrane that resists softening and reshaping once cured, and therefore must be bonded using an adhesive seam tape. EPDM is a cost-effective and time-proven solution for flat and low-slope roofing systems with demanding installation circumstances.

PVC and TPO are thermoplastic membranes that remain pliable when heated, and can therefore be heat welded to form extremely durable bonds at each seam. Both PVC and TPO are available in a number of different formulations, and provide a high degree of flexibility with regard to budgetary constraints.

Though Sun Roofing installs EPDM, PVC, and TPO roofing systems, the specifics of your building project will determine the options that are right for you. Our proposal process is designed to clearly illustrate the advantages and disadvantages of every applicable roofing solution so you can make an informed decision.

Chances are that if you’ve seen a commercial building, you’ve seen a metal roof. Commercial metal roofing is typically steel, though stainless steel, aluminum, zinc, copper, tin, and even titanium are sometimes used for specialty installations. No matter the material, metal roofing is available in a variety of different gauges, or thicknesses, and in the case of steel roofing, is galvanized using zinc or a zinc/aluminum alloy called galvalume to protect against rust. Metal roofing can also be painted to match a design aesthetic, or coated to increase energy savings.

Metal roofing is installed as panels that can either be mechanically-fastened (corrugated) or “snapped” together using a mechanical seam fastener (standing seam). For low-slope applications, structural panels are used. These panels are shipped with factory-applied sealant to ensure that they remain watertight, and have higher seams than those seen on the architectural panels used in steep-slope installations. Structural metal panels require no underlying roof deck to support them, provide excellent defense against wind uplift, and can be factory formed to extreme lengths to avoid horizontal seams in many applications.

Although the cost can be prohibitive for some projects, a brand new metal roof is a beautiful thing to behold. The durability, long service life, and low maintenance requirements can often justify the initial cost. Metal roofing is available in a staggering number of designs and configurations, but our experts will be happy to cut through the noise and help you to decide if a metal roof is the right choice for you.
