What are shingles?

Asphalt roof shingles are one of the most affordable roofing materials today. Housing contractors typically used it on roof coverings because of its availability. Base mats of shingles are made from either paper or glass fiber. The mats are then coated with limestone powders, asphaltic mixture, and other mineral stabilizers or fillers.

For aesthetic purposes and durability of the shingles, contractors apply granules to give them color and weight. The granules also help block the asphalt from sun damage to make the last long. Most granules composed of crushed stones coated with ceramic mixture.

In general, shingles are:

  •    One-third granules
  •    One-third asphalt
  •    One-third filler

The mat only counts for a small fraction of the total weight of the shingles. The asphalt roof shingles come in different shapes, sizes, and thickness. But three-tab and laminated kind is the most common type of shingles. When installed, the three-tab shingles will look like a common brick pattern. The laminated variation composed of one full shingle and half a shingle attached together to give them a bolder look. The heavier or the thicker the shingle is, the more expensive it becomes.

What is hail damage?

Hail damage is defined as any reduction of water-shedding capability or a decreased in the expected term of any roofing material. Hail damage on shingles includes:

  •    punctures
  •    tears
  •    fractures (bruises)
  •    broken edges torn edge

Bruises on hail roof damage contain indentation with cracks in the mat that may feel soft. These bruises are easily spotted because of missing granules from the impact area. Some even expose the asphalt materials of the shingles.

Asphalt roof deterioration vs Hail damaged roof

Asphalt shingles also deteriorate with age and are far different from hail damage. As the components of the shingles break down, it also shows signs of deterioration. Under a trained eye, that of certified roof inspector can detect the difference. The extent of the aging process of the shingles includes several factors like:

  •    the quality of the asphalt
  •    shingle color
  •    roof pitch
  •    slope direction
  •    attic ventilation

The most common wear problems of aged asphalt shingles are as follows:

  •    blistering
  •    clawing
  •    cupping
  •    crazing
  •    flaking
  •    splitting

In most cases, these wear and tear signs are not discovered until an inspection after a hailstorm. But it may not necessarily mean hailstones created or forced the damaged.

Asphalt shingle irregularities

Over the years, particularly for roof 10 years or older, it may show signs of deterioration either from poor maintenance of from aging. These damages are not associated with hailstones impact. Some of these irregularities may look like rounded damage and can easily confused with hailstone damage.

Shingle Defects includes:

  •    blotches on the surfaces of the shingles
  •    asphalt exposed in lower laminate
  •    insufficient three-tab adhesion or glue
  •    missing lines asphalt and granules

Unlike cement, shingles are vulnerable to hail damage especially if they have little support along rakes, ridges, eaves, and valleys. The edges of shingles are also susceptible being broken or chipped. The weather plays an important look in the overall look of the shingled roof. For this reason, it is important for a professional to fully examined hail roof damage.
