Sun & Heat Damage
Myrtle Beach's intense sun and heat accelerate roof aging. UV rays break down shingle materials while extreme temperatures cause expansion and contraction damage.
Signs of Sun & Heat Damage
How Sun & Heat Damage Roofs
UV Degradation
Ultraviolet rays break down the chemical bonds in asphalt shingles. The oils that keep shingles flexible evaporate, leaving them brittle and prone to cracking.
Thermal Cycling
Daily heating and cooling causes shingles to expand and contract. Over years, this movement loosens fasteners and creates gaps.
Granule Loss
The protective ceramic granules on shingles wear away from UV exposure. Without granules, underlying asphalt deteriorates rapidly.
Attic Heat Buildup
Poor ventilation traps heat in attics, baking shingles from below while the sun bakes them from above—double the damage.
Heat-Resistant Roofing Options
Metal Roofing
Reflects heat, lasts 50+ years, ideal for coastal climates
Cool Roof Shingles
Reflective granules reduce heat absorption by up to 40%
Tile Roofing
Natural thermal mass and airflow channels dissipate heat
Frequently Asked Questions
How long do shingles last in Myrtle Beach's climate?
Standard asphalt shingles typically last 15-20 years in coastal SC due to intense UV and heat exposure. Architectural shingles may last 20-25 years. Premium materials and proper ventilation can extend lifespan. We can assess your roof's remaining life expectancy.
Can damaged shingles be repaired or do I need a new roof?
Isolated damage can sometimes be repaired by replacing individual shingles. However, if sun damage is widespread (common with older roofs), replacement is more cost-effective than patchwork repairs that will continue to fail.
How can I protect my new roof from sun damage?
Choose light-colored or reflective shingles, ensure proper attic ventilation, and consider cool roof coatings. We also recommend regular inspections to catch minor issues before they become major problems.
