Even if you take great care of your commercial roof from the installation day, UV damage is sneaky and tends to wear the material before its expected lifespan. Without proper protection, all types of roofing will eventually develop serious problems. Sun damage affects your roof almost every day of the year, especially thanks to Kansas City’s weather patterns.
Don’t let roof UV damage lead to costly damage that is hard to spot until leaks occur. Get on top of this common cause of commercial roofing damage with our help.
UV Roof Damage and Different Types of Commercial Roofing
UV rays have different effects on roofing depending on the material. Most materials react similarly to sun exposure, but the methods for protecting them from UV rays vary. Find the right sun damage roof prevention solution based on the material of your roof to ensure long-term reliability.
| Roof Type | UV Resistance Challenges | Common Solutions |
|---|---|---|
Single-Ply Roofing |
Older materials may crack due to sun exposure if they lack stabilizers. | Use coatings on older roofs; newer systems benefit from regular maintenance to retain flexibility. |
Built-Up Roofing (BUR) |
Upper layers can stiffen, blister, or degrade into powder after prolonged UV exposure. | Protect with ballast (e.g., stone or granules), UV-resistant coatings, or built-in stabilizers. |
Modified Bitumen Roofing |
UV rays can cause blistering or delamination over time. | Apply specialized coatings or use ballasts; supports panels or decks to block UV and reduce foot traffic. |
Other Commercial Roofing Types – Metal and Tile
Even rarely used commercial options like metal and tile roofs are susceptible to damage from UV rays. While metal roofs come with protective coatings installed from the start, they may need additional coating in the future to restore the protection. Tiles are relatively UV resistant from the beginning, depending on what they’re made from. Coatings can help them last longer as well.
Preventing UV Damage to Commercial Roofs
In addition to UV protection specific to the commercial roofing material you’ve chosen, you can take many basic steps to protect the roof regardless of its design.
Regular Inspections
Inspections are the key to catching the early warning signs of roof damage, including UV rays. UV exposure has visible signs at the early stages, like color changes, a dusty appearance to the surface, cracking materials, and blistering. Waiting too many months to inspect the roof could let the damage spread, the more you realize it, leading to costly repairs or even the need for full re-roofing.
Protective Coatings
Whether your roof is new or starting to show signs of aging, cool roofing solutions could help it last longer in multiple ways. Protective coatings physically stop UV rays from reaching the original roof surface, protecting it from the sun.
Yet reflective and white-colored coatings also reduce heating, further extending the life of the material and helping it better resist UV exposure. Some of these roof coatings for sun damage even help fill in tiny cracks from the damage to the surface. This can stop leaks before they start, giving you more years of life from the same commercial roof.
Maintaining Protective Layers
In addition to adding specialty coatings or other products not installed initially as part of the roof, it’s important to top up any existing materials meant to protect against UV rays. For example, many commercial roofs include a layer of gravel, ceramic granules, or other ballast material designed to both hold the roof down and protect it from the sun. Letting those layers wear or blow off without replacement only accelerates wear and tear.
Encouraging Good Ventilation
Venting slows down a roof’s aging process by lowering heat and moisture levels. Dry, cool roofing materials are more resistant to UV damage over time. Once a roof starts to develop one form of damage, it’s less resistant to the rest. Good ventilation supports all other commercial roof UV protection efforts.
Choosing the Right Roofing Materials
Each climate poses different challenges to commercial roofing materials. That means that some materials work better than others. In Kansas City, PVC, TPO, and modified bitumen roofs are good options. Single-layer roofs are easy to keep clean and accept many coatings when they need extra protection from UV rays. Modified bitumen is easy to maintain, coated with protective ballast, even when high summer winds come.
You don’t have to pick the right solution for your commercial roof alone. Let Delta Innovative Services evaluate your roof’s current condition and advise you on the best restoration.
