Hail is nearly unpredictable. It could happen during a really cold winter day, but it could also happen during a nice summer day. Hail occurs when a warm draft of air pushes moist air up. The higher it goes, the colder it gets and soon, the moisture creates ice chunks. They either fall straight down or get blown by stronger winds to far places. This is why relatively sunny places can get sudden hailstorms.
Effects of Hail on Rubber Roofs
Synthesized rubber roofs are gaining popularity as of recent. They are effective at keeping heat in or reflecting it, mostly due to color. They also last quite long, with companies providing warranties as long as 30 years.
When to comes to hail, rubber roofs are champions of enduring it. The rubber materials absorb most of the shocks and reflect the rest. Light hail storms are pretty much shrugged off, but for hail storms with tennis ball sized chunks, or roofing that’s over 15 years old, you need to watch out for the following:
- Small Tears – This is caused by nearly invisible cracks in the roofing. This is mainly due to aging and when a big enough chunk hits hard, the cracks can give way on impact. Small tears can only lead to bigger ones as cycling heat and cold can cause it to expand.
- Tenting or Bulging – Caused when a chunk of hail hits an old portion of the roof. The layers beneath aren’t aligned, causing the top layer to separate and for a bulge. One good hit and this tenting can expand and cause tears.
Effects of Hail on Shingles
Shingles can be either wood, fiber cement, slate, ceramic, or asphalt. They are durable, time-tested, and time-honored roofing for the cozy suburban home. They can withstand hailstorms that throw one-inch chunks or smaller. With consecutive battering, the following can happen to your roofing.
- Granule Loss – Some shingles are made with mineral granules as the top coating. Direct hail impacts can cause the protective granules to separate, revealing a potentially weaker layer under it. This could cause bigger problems in the future, as the inner layers are exposed to the elements.
- Seal Loosening – Constant rattling and impact can loosen the seals that keep the shingle in place. This problem is often unseen, so careful inspection must be done after every hailstorm. If the seal is loose enough, it could case a shingle break-off and expose your roof to further damage.
Effects of Hail on Steel Roofing
An effective and affordable roofing that resists all the elements. Treated corrugated iron can withstand heat, rain, cold, and hail with surprising tenacity. Steel roofing can maintain its structural integrity even after 20 years, but what do you need to watch out for?
- Deep Dents – Steel roofing might get a small dent or two after a hailstorm, but it will not break or tear. Deeper dents, however, can cause water puddles and is susceptible to further damage. Consider replacing sheets with dents deeper than an inch.
- Scrapes and Skids – Some roofing may come with aesthetic textures that can get scraped off by a whopping hailstorm. This will not affect the strength of the roof, and will probably just give the roof a bit more personality.
