Can excessive sun exposure damage your roof?

When examining or building a roof, sun exposure is often overlooked if you’re not a professional. Especially in Florida, the strength of ultraviolet rays can cause major damage to all types of roofs. The structural integrity of your roof can be compromised by damage such as bleaching or thermal shock. 

Here are signs your roof may have damage caused by sun exposure:


While roofs are designed to last a long time, pigmented materials, such as certain types of shingles, can start to discolor over time. If you notice some shingles are starting to look lighter than the original color, it's important to reach out to a roofing contractor you trust so they can tell you if it needs repair right away. 

Crumbling Shingles

If you start to notice pieces of your shingles in the gutter or on your lawn, this means your roof has had as much sun exposure as it can take. This is common with older homes or businesses that haven’t had enough roofing TLC. Years of sun exposure can cause the old shingles to decay or crumble, leaving your residence exposed. When speaking with a roofing professional, ask about roofing materials that are more resistant to harmful UV light. 

Heat Damage

Your roof protects the home from heat by absorbing and containing it so it doesn’t seep inside. In Florida’s long summers, your roof is working overtime to keep the inside cool. As temperatures rise, you will start to notice the roofing tiles or shingles lift from the corners or buckle. This is normal, but it’s important to regularly inspect your roof before the shingles start to peel or let elements inside the home. 

Thermal Shock 

If you have a metal roof, it’s important to take note that those materials can still suffer in extreme heat. Thermal shock causes the metal to destabilize, causing it to thin and crack. Cracks let in moisture, which leads to problems inside the home like moss growth, leaks, mold, or the support that holds the roof to rot. Trapped moisture is the leading cause of a roof needing to be replaced immediately. Thermal shock can also lead to the roof becoming brittle, which makes it less likely to be able to withstand rain, hail, or debris.
