You shouldn’t be too concerned when a few granules fall off your roofing system, since manufacturers usually add more granules than they need to. If one too many, however, have fallen off your new roof and it happened after an extreme weather event, then there is some cause for concern.
Mobley Brothers Roofing & Restoration, one of the top roofing contractors in the state, elaborates on the different causes of weathering.
Age of the Shingles
The granules on a shingle naturally lose adhesion over time. The older the shingle, the more granules it will lose. Granule loss doesn’t mean your roof is damaged; it’s just time for a new residential roof replacement.
Extreme Weather Events
Always check your roof for signs of damage after extreme weather events. The heavy winds from storms can blow away debris that can scratch off quite a few granules. Hailstone impact can cause patches of loose shingles to appear as well.
Just to be on the safe side, you can also call a roofing contractor to inspect your roof for any signs of damage you might have missed. After all, relatively minor damage can worsen if left unattended for a while.
As mentioned earlier, manufacturers add more granules, 40% to be exact, than needed to the shingles; if your new roof loses some shingles, check if the embedded granules remain. Although the excess granules are linked with the embedded granules, they don’t adhere strongly to the surface and fall off quickly.
As a general rule, pay attention to the number of granules lost and the age of the roof and whether or not they’re disproportionate. A new roof that’s losing too many granules likely has manufacturer defects.
