Hail Pocks; A Sign of Roof Hail Damage

roof-hail-damage-fort-collinsIf you are like the typical homeowner in Northern Colorado you have probably heard a lot about hail and the damages that it can cause. More likely than not it has come from a roofing company saying you need your roof replaced or friends or family that were affected by a recent hail storm. Now there are a lot of roofers that will just follow a hail storm and tell you that the hail has damaged your roof without any real explanation as to why. Typically its something as basic as hail pocks indicating where the hail damaged the shingle or missing granules shedding off of the roof. Both of which are very much indications of hail damage, but most people are still skeptical as to why the roof will need to be replaced since the roof is not leaking. As much as the roofing salesman says it is imperative that you replace the roof as soon as possible before it leaks, this tends to be just a sales tactic to close more deals quicker. In most cases a roof that is damaged by hail will not leak for sometime. It is damaged, but unless there are current leaks or actual holes in the shingles, chances are you should not lose any sleep… right away.

Hail Damage to a Roof is defined as:

  • Functional Damage Hail diminishes the ability of a roof to shed water
  • And/Or
  • Reduces the roof’s expected long-term service life.

The fact is that when large hail (typically 1” in diameter or larger) hits your roof it ruins the lifespan and integrity of the shingles. It does not mean it will leak right away but the best explanation is this. Roof shingles are made up of 90% asphalt and when the hail hits these shingles hard enough it not only knocks off the granules, but also cracks or fractures the asphalt and matting that makes up the shingle. Initially these cracks are very minor and are identified as “pock marks”. These micro-fractures begin to expand and contract like that cracks in our roads. Once the cracks become large enough they eventually allow water to leak into the roof. This is why insurance is paying for the replacement of your roof, to protect your biggest investment, your house, from future damage.

Overall, I felt that this explanation is necessary as too many homeowners don’t truly understand what is going on when a hail storm hits. Too many roofers use scare tactics and urgency to sell. I believe that in order to gain a customer’s trust a homeowner needs to be educated on all the details of the process right down to the very reason the roof is being replaced, and not just “because large hail left marks on the roof.” Homeowners need to be educated and find a contractor who is knowledgeable and willing to share that knowledge with them. After all, the homeowner is investing in the
contractor to rebuild the largest investment and home of their family, and not just replace a roof.


  1. Thanks for explaining what some signs of hail damage can look like on a roof. It’s good to know that minor cracks in the shingles could expand eventually, so it seems important to watch for those. I’m kind of interested to learn if you should use a magnifying glass when looking for the cracks or if you should just examine the roof for a few days after a storm.
