The point of having a roof over your head is to protect yourself against the weather. For some, this is as simple as shade from the sun and a shield from the rain. For others, the roof has to withstand harsh winters, ever-changing heat and cold, and hail storms.
Hail may not be the most destructive force that could batter your roof, but it’s one that damages roofs in ways often unnoticed. Despite hail being made up of water, you’ll be surprised how tough ice can be. Even well-forged knives can crack and split when you hit blocks of ice with them. Now, imagine a small chunk of ice traveling at a speed of 20 kilometers per hour and it hits your roof. With some roofs like shingles, hail could just be a frosty splatter. For more modern materials like EPDM roofing, they could shrug off even big chunks of hail due to their shock absorbing properties.
Eventually, though, wear and tear will happen over time. Hail isn’t the only source of stress and damage on your roof. At some point, a certain particularly heavy hailstorm can damage your roof. It’s important that after every hailstorm, you inspect your roof because you’ll never know if that little ice chunk might have hit a small crack and turned it into something that will cause leaks. Surprisingly, what causes the most damage to your roof is not the hail impacts, but the water and moisture related damage that follows.
How to Find Hail Damage On Your Roof
These are general ways to determine if your roofing has suffered damage from Hailstorms. Some of them are hard to spot so it’s important that you climb onto your roof to inspect them. If you see any of the following, they are worth checking out for further damage assessment.
For Stone/Asphalt/Mineral Shingle:
- Granules in your roof or gutter.
- Shiny spots or black spots (depending on shingle color)
- Soft spots or areas with either dimples or humps
- Cracks and holes
- Shingles that are out of alignment
For Wooden Shingles:
- Out of place patterns or discolorations
- Splits and cracks that have darker color than the shingle
- Dents and impact points.
- Sharp-edged splits which can mean deeper cracks.
For Steel Roofing:
- Streaks or peeling in the paint
- Dents deeper than 2cm or wider than an inch
- Chipping of any sort, even small ones
For EPDM or Synthetic Material Roofing:
- Wrinkles in the rubber
- Dips and bumps
- Tears of any sort
- Discoloration of the rubber
It’s always worth inspecting your roof after a hailstorm. Your roofing may easily shrug off a light storm, especially one with easily crunched hail chunks, but it’s only a matter of time. A sudden gust of wind could have hail travel at faster speeds. All it takes is one small weak point for a chunk of hail to bore a hole or a crack in the roof. Afterwards, water and moisture could leak in and cause molds which can really cause damage.
