How Metal Roofing Stands Up to San Antonio’s Weather

San Antonio has a humid subtropical climate that brings very hot summers and varying weather all year round. If you’re considering metal roofing, how well will it stand up to San Antonio’s weather conditions over time? Read on to learn why metal is an excellent roofing choice for withstanding San Antonio’s weather patterns.

Resistance to Heat

Summers in San Antonio can mean daily high temps in the 90s to 100s. 2023 will go down as a record hot summer with temps above 100 degrees. This intense heat can take a toll on traditional asphalt shingle roofs, causing faster deterioration, warping, and cracks. How well a metal roof will reflect solar radiation will depend on its color. Metal roofing holds up extraordinarily well in the San Antonio summer heat because it reflects solar radiation rather than absorbing it like darker shingles. This reflectivity enables metal roofs to deflect the sun’s rays and transmit less heat into the attic and interior living spaces. Properly insulated metal roofs with radiant barriers can reduce attic temperatures by up to 30 degrees compared to asphalt shingles. For homeowners, this improved heat reflection directly translates into lower air conditioning bills and savings on energy costs. This significant cut in utility expenses makes a highly reflective, energy-efficient metal roof an excellent return on investment for local homeowners.

Hail Protection

Metal roofing is inherently very impact-resistant due to its hardy construction and interlocking panels. The seams between the metal panels allow for expansion and contraction to dissipate impact energy. The steep slope and smooth texture of metal roofing also allows hailstones to deflect and bounce off rather than accumulate on the surface and cause dents like on textured asphalt shingles. This resilience against hail impacts gives homeowners in storm-prone San Antonio added peace of mind that their property and belongings will be protected against severe weather events. The hail resistance of metal roofing provides a key advantage that more than justifies the investment for many local homeowners.

Wind Uplift Capabilities

North Texas, including the panhandle, is positioned within the region known as “Tornado Alley.” Powerful storms frequently occur in the area, bringing the threat of high winds and tornado activity. While San Antonio is not directly within the Tornado Alley region, powerful storms still frequently occur in the area, bringing the threat of high winds, hail, and occasional tornado activity. These intense winds can wreak havoc on vulnerable roofs, causing major uplift damage or even full removal of the roof deck. However, modern engineered metal roofing systems can be specifically designed and installed to withstand very high wind uplift forces. The interlocking panels are tightly overlapped and the metal-to-metal clip connections create a unified barrier against the winds. The entire roof is secured as a cohesive system and wind forces are distributed across the roof rather than lifting a single area. Metal roofing manufacturers test products to meet wind resistance standards like UL 580 and FM 4471. Homeowners can have peace of mind knowing their metal roof provides excellent wind performance that far surpasses traditional asphalt shingles in San Antonio’s stormy climate.

Rain & Storm Durability

Metal roofing stands up to heavy rains, thunderstorms and constant moisture far better than wood or asphalt shingles. During San Antonio’s lengthy rainy seasons and intense downpours, metal roofing provides reliable wet weather performance. Unlike porous asphalt, metal roofing panels will not absorb rainwater. This prevents water retention issues that can lead to roof leaks, mold growth, rotting roof decks and interior water damage. Metal roofing is also impervious to moisture-related warping, curling and breakage. Advanced metal roof coatings further enhance water shedding capability and moisture resistance. The protective finishes allow metal roofing to maintain its like-new appearance even after decades of wet weather exposure in San Antonio’s humid climate. Homeowners can rest assured knowing their belongings stay reliably dry inside, despite the moisture and deluges brought by local storms.

Long-Term Endurance

W ith proper routine maintenance, metal roofing reliably endures decades of San Antonio’s intense sun, storms, wind and rain. While asphalt shingle roofs typically need replacing every 15-20 years, metal roofs can last 50 years or longer even in demanding South Texas weather conditions. With just simple periodic upkeep like clearing debris and re-sealing joints as needed, you can expect a metal roof to provide lifelong protection for your home. Unlike fragile shingles that become brittle and crack over time, metal roofing resists deterioration in the strong UV exposure, temperature fluctuations and moisture of San Antonio’s climate. The long-term durability of metal eliminates the need for continual roof repairs, leaks and early re-roofing that homeowners deal with when using shingles or other materials. Investing in a quality standing seam metal roof truly provides decades of reliable performance and protection from the elements.
