As summer rolls into Wichita, Kansas, it brings with it a familiar set of challenges for commercial property owners: scorching temperatures, intense UV radiation, and the ever-present threat of severe thunderstorms packing high winds and hail. Your commercial roof, a critical asset, bears the brunt of these conditions, and its ability to withstand them directly impacts your building’s energy efficiency, structural integrity, and the comfort of your occupants.
Solid Rock Commercial Roofing understands the unique seasonal pressures on Wichita’s commercial roofs. This article will explore the significant impact of summer heat on various roofing materials, introduce effective “cool roofing” options that can drastically reduce your energy bills, and provide essential tips for preparing your commercial roof to brave Wichita’s summer storms.

The Impact of Summer Heat on Commercial Roofing Materials
Wichita’s summers are notoriously hot, with prolonged periods of intense sunlight. This relentless heat takes a significant toll on all types of roofing materials:
- Thermal Expansion and Contraction: All materials expand when heated and contract when cooled. On a roof, this daily cycle of extreme temperature swings creates constant stress on membranes, seams, and fasteners. Over time, this can lead to:
- Cracking and Splitting: Rigid materials may crack, while flexible membranes can develop fatigue cracks.
- Seam Separation: Adhesives and welds at seams can weaken, leading to separation and potential leaks.
- Fastener Back-out: Fasteners can loosen or pull out from the roof deck, compromising the system’s attachment.
- UV Degradation: Ultraviolet (UV) radiation from the sun is a primary enemy of many roofing materials.
- Material Breakdown: UV rays break down the chemical bonds in plastics (like TPO and PVC) and asphalt-based materials, leading to brittleness, chalking, and a loss of elasticity.
- Granule Loss: On asphalt-based roofs (like modified bitumen with granular surfacing), UV exposure combined with thermal cycling causes protective granules to shed, exposing the underlying asphalt to further degradation and weakening.
- Heat Build-up in the Building: A dark, non-reflective roof can absorb an immense amount of solar energy, transferring that heat directly into your building’s interior. This “heat gain” forces your HVAC system to work overtime, leading to:
- Skyrocketing Energy Bills: Increased cooling demand directly translates to higher electricity consumption.
- Reduced Occupant Comfort: Even with robust AC, constant heat infiltration can make it harder to maintain comfortable indoor temperatures.
- Equipment Strain: Overworked HVAC units experience more wear and tear, leading to higher maintenance costs and shorter lifespans.
Cool Roofing Options: A Smart Investment for Wichita Summers
“Cool roofs” are designed specifically to address the challenge of solar heat gain. By reflecting more sunlight and absorbing less heat, they keep the roof surface cooler, which in turn keeps the building interior cooler.
- Reflective Coatings:
- Description: These are highly reflective, typically white or light-colored, liquid-applied coatings (often acrylic or silicone-based) that can be applied over existing compatible roofing systems like modified bitumen, metal, or even some single-ply membranes.
- Perks: They significantly reduce roof surface temperatures (by 50-60°F or more), dramatically lowering heat transfer into the building. They are a cost-effective way to convert a conventional roof into a cool roof, often without a full tear-off. They can also extend the life of the existing roof.
- Wichita Relevance: Ideal for immediate energy savings in our hot climate.
- White Single-Ply Membranes (TPO & PVC):
- Description: Thermoplastic Polyolefin (TPO) and Polyvinyl Chloride (PVC) are popular single-ply roofing membranes. They are inherently light-colored (most commonly white) and highly reflective.
- Perks: Offer excellent reflectivity and emissivity (ability to release absorbed heat). They are durable, puncture-resistant, and provide a strong, flexible, and often heat-welded seam system for superior waterproofing.
- Wichita Relevance: A top choice for new flat or low-slope commercial roof installations seeking long-term energy efficiency and robust performance against sun and storms.
- Metal Roofing with Reflective Coatings:
- Description: While metal itself is a good conductor, specialized cool-color metal coatings are highly effective at reflecting solar radiation.
- Perks: Metal roofs are exceptionally durable, fire-resistant, and have a long lifespan. When combined with cool coatings, they offer both robust protection and significant energy savings.
- Wichita Relevance: A premium option for businesses seeking extreme durability against hail and wind, combined with strong energy performance.
- Spray Polyurethane Foam (SPF) with Reflective Coatings:
- Description: SPF provides exceptional insulation (high R-value) and is typically coated with a highly reflective, light-colored elastomeric coating.
- Perks: The seamless, monolithic application creates an outstanding thermal barrier and eliminates thermal bridging. The reflective topcoat further enhances energy efficiency. It also has excellent wind uplift resistance.
- Wichita Relevance: Ideal for warehouses and other large commercial buildings where maximizing insulation and energy savings is paramount, especially in a wind-prone area.
Preparing for Summer Storms: Fortifying Your Roof Against Wind and Hail
Wichita’s summers aren’t just hot; they’re also synonymous with severe thunderstorms capable of delivering powerful winds and damaging hail. Proactive preparation is key to mitigating storm-related roof damage.
- Pre-Season Professional Inspection: Before the severe weather hits, schedule a comprehensive roof inspection with Solid Rock Commercial Roofing. We will:
- Identify any existing vulnerabilities, such as loose seams, compromised flashing, or deteriorated materials.
- Check for adequate securement against wind uplift, particularly at edges and around penetrations.
- Assess the general condition of the roof for any “bruises” or weakened spots that might be susceptible to hail impact.
- Ensure drainage systems are clear and functioning optimally to prevent water ponding during heavy downpours.
- Clear Debris and Ensure Drainage:
- Roof Surface: Remove leaves, branches, dirt, and any other accumulated debris that could block drains or scuppers. Debris can also become projectiles in high winds, causing damage.
- Gutters and Downspouts: Clean out gutters and ensure downspouts are clear to allow for rapid water runoff during intense rainfall. Blocked drainage can lead to ponding, which exacerbates leaks and stresses the roof structure.
- Address Minor Repairs Promptly: Don’t ignore small issues identified during inspections. A small crack, a loose fastener, or a minor tear can quickly escalate into a major problem during a severe storm. Timely repairs are cost-effective and prevent catastrophic failures.
- Trim Overhanging Branches: If your property has trees with branches overhanging the roof, trim them back. Strong winds can snap branches, causing them to fall and puncture or tear the roofing membrane.
- Secure Rooftop Equipment: Ensure all rooftop HVAC units, vents, antennas, and other equipment are securely fastened to their curbs or mounting systems. Loose equipment can become wind-borne projectiles or tear free, damaging the roof.
