Gravel in gutters. You may see an influx of granules in your downspouts after a storm. It allows excess water to percolate. Shingle sediment is made up primarily of sand like granules or grit that separate from asphalt shingles and other small matter that sticks to the roof surface and washes into gutters. Granule loss on a new asphalt roof loose mineral granules wash down the roof and will appear in gutters and at the ends of downspouts.
It seems to be most prevalent early and later in the shingles life. Reverse curve gutter guards are made of a curved piece of thin metal that directs water into the gutters and everything else onto the ground. A french drain is a system for eliminating excess water from the soil. It is common to see granules washed into the gutters and downspouts of your home after a new roof has been installed.
