Why are there granuals on roof shingles.

Granules are a critical ingredient to asphalt shingles and their ability to withstand the harsh weather conditions that they endure year after year not only from the sun but from rain hail and snow throughout the winter. Granules were added to the design of shingles because they help keep uv rays off the shingle s asphalt coating they make the shingles more fire resistant and they make it easier for manufacturers to package the shingles. You will notice that newer roofs will have most of the granules still attached to the shingles compared to older ones. Originally bonded to the shingle itself small granules eventually break off creating the gritty mass typically found on top of a roof.

Tree branches rubbing on the roof this creates clearly defined swept areas of excessive granule loss. Why do roof shingles have granules. The ceramic granules on asphalt shingles provide a very important function. What s really crazy is the technology and thought that goes into making these granules.

Contains a uv blocker that protects against damaging sunlight improving the durability of the membranes and the system color lock ceramic firing helps maintain the true shingle color weather resistant and designed to meet industry and code requirements. It protects the roof from ultraviolet uv rays especially the asphalt coating so that the asphalt membrane remains safe it provides some level of fire resistance and add aesthetic appeal and beauty because some granules come in colors. A severe storm a strong thunderstorm is going loosen shingle granules and a hail storm is even worse usually also with pock marked shingles. Mineral granules were added to the design of shingles because they help protect your roof from excessive sun exposure which can eventually lead to damage and hasten the need for a roof replacement.

Shingle granules shield the shingles from uv rays and increase their fire resistance. These uv rays will rapidly disintegrate asphalt and the thin fiberglass mat. Granules in your asphalt shingle are actually small bits of the shingle s top surface. Granules also add increased fire resistance to your roof offering another layer of protection to your home.

Roof shingle granule loss due to defective roofing product usually exposes the shingle substrate in premature bald patches and is identified by bald spots or exposed shingle substrate on roofs early in their chronological life often distributed uniformly over the roof or in areas of the roof where shingles from a particular pallet of roof shingles were installed. One of the ways asphalt shingles have been perfected over the years is with granules.
