When Hail Damages Roof Shingles

A Roof has always meant to protect our families during all kinds of weather, may it be rain or shine. But when it comes to unpredictable weathers such as hail storms or strong wind, the roof above our heads might be affected. If we do not take the time to have a roof inspection after turbulent weathers or even ignore possible roof damages, the security and comfort of our families will be at risk and you have no one to blame but yourself.


It is also a good idea for homeowners should find out whether the warranty on their roofing covers any damages caused by hails. We might not be masters of roofing or have any knowledge regarding roof damages but these are some key tips that homeowners should keep in mind and let these tips motivate homeowners to be vigilant towards their roof condition.[/vc_column_text]


To start off, would the damage on roof be immediately noticeable?

Not necessarily. Hail could leave an impact of latent damage that would cause the shingles to age prematurely before it supposed to. This is due to the long period of anyone could actually notice latent damage after an unpredictable hail storm, which could go up to months or years later. Thus, the ageing process of shingles will speed up when there is underlying and unnoticeable latent damage. Upon saying so, damages on shingles can only be identified through obvious visual damage as there is no certain way to determine any shingle damages.


As a homeowner, what sort of signs should I look out for if my roof is damaged?

Do look for any indentations and/or fractures on the shingle’s surface. There is no precise size of indent or fracture pattern to indicate any sort of damages as hail comes in different size, shape and hardness so homeowners should take caution immediately if any indentation and/or fractures are seen. If there is none, do not take consider the roof being undamaged and look for any irregularities on its metal flashings, siding, chimney caps, and also skylight flashings. If the roof and its parts look perfectly fine, then do look out for clusters of granules coming off in a random pattern and exposing asphalt along the way.


How many types of roof damages out there?
The common ones are:


• Granule loss – The loss of granule upon any time of impact may be accompanied by a surface depression. It wouldn’t matter if the roof is losing granule gradually or altogether by a hail storm because the direct exposure of the asphalt coating to the elements would accelerate the aging process of the shingle. So losing granule is not only making the roof look bad, it wouldn’t work its purpose and adding those loose granules onto the damaged shingles with asphalt cement or in other terms “sugaring”, is not exactly a permanent solution.
• Cracks in the granule-asphalt surfacing – These cracks would radiate outward if any impact is acted upon it and the cracks are perfectly visible if high winds blew the shingles upwards and backwards.
• Exposed fibreglass mat – This happens when a hail crashed onto the granule-asphalt surfacing and caused it to break away from the fibreglass mat and letting the mat be exposed.
• Fractured fibreglass mat – The fibreglass mat is fractured when there are tears radiating out from the points of impact and this may or may not be visible for homeowners to immediately notice. If the fractures come unnoticed, eventually the fractures will become cracks and tears as the shingles age.
• Loosening of the self-seal strip – The weakening of the self-seal strip offers a possibility for a future shingle blow-off but unfortunately, this damage is not necessarily visible for homeowners to notice.


Lastly, is it possible to only replace several damaged shingles or replace the entire roof altogether?


It is not a problem to only replace a few storm-damaged shingles if the damage is confined to one plane of the roof. The nails that’s being removed from the surrounding shingles of the individual shingles being replaced must be replaced as well and resealed it by hand to maintain the roof’s function and purpose. Alternatively, if the position of the latent damage is uncertain and if it is, there is a possibility of latent damage on the surrounding shingles. The difficulty on assessing the condition of the surrounding shingles, a complete roof replacement is often recommended to ensure the long-term performance and condition of it.
