The life expectancy of your shingles

Understanding how the different components of a roofing system work and how fibreglass laminate shingles are designed is important in protecting your home. Shingles must endure everything from the sun’s scorching heat and its ultraviolet radiation to the effects of seasonal and environmental changes. They may even be subjected to the effects of thermal shock caused by quickly changing weather conditions. The scorching heat of the sun can raise the temperature of the roof’s surface to extremes. This can affect the life expectancy of shingles. Proper ventilation helps to reduce the fluctuation in the temperature of your roof over the course of the day and can reduce your roof’s overall ambient temperature. Besides the heat, the sun is also a source of ultraviolet radiation, making the asphalt layer of the shingles age more rapidly. To protect against this, shingles are covered by coloured granules to protect the asphalt from the sun.

BP shingles have zinc oxide built right into their products.
This provides many years of protection against algae built up on your roof.

So, the long and the short of it is, the better the product, the more extended the shingle will last in any climate, and proper ventilation and installation are key components in the life span of your roof.

The advantages of laminate shingles

Do Not because of warranty issues.

Easy to repair.
As easy as BP laminated shingles are to install, it’s equally easy to repair if it gets damaged.


Good performance record.
BP laminated shingles come with a limited lifetime warranty.  Extended warranties are available for up to 50 years, depending on your existing attic ventilation.

Style options.
The most frequently used product is the laminates available in many colours and deep shadow lines.


Our full inspection on a shingle roof include:

Wind Damage Inspection:

J.O.N. Roofing Ltd inspects every roof for damage caused by strong winds. While missing shingle tabs can easily be seen from the ground, it’s sometimes harder to see shingles creased from being blown up by wind or shingles that are no longer sealed properly because of dirt and debris.

Repairability Inspection

Not every roof that leaks need to be totally replaced. We can often repair any damage caused by improper installation or storm damage if it is localized. To determine our ability to repair your roof, we test the shingles to determine their pliability. If shingles are too brittle, it may not be possible to replace one shingle without damaging the surrounding shingles.

Window Inspection:

Sometimes, a homeowner calls with us to inspect what they mistakenly think is a roof leak, but what they actually have is a window leak. If any windows are above the roofline, J.O.N. Roofing Ltd inspects the window to ensure proper installation and window flashings.

Step Flashing inspection:

Step Flashing is used at the diagonal roof to wall transitions. Improperly installed or rusted step flashing is often the cause of major leaks that are sometimes hard to pinpoint. J.O.N. Roofing Ltd inspects your step flashing, ensuring that it is securely fastened and not rusted from years of exposure to the elements.

Counter Flashing Inspection:

Counter Flashings are commonly used around chimneys, overstep flashings, and anywhere else there might be a roof to wall transition. J.O.N. Roofing Ltd inspects all counter flashings to ensure they are properly sealed

Drip Edge Inspection:

J.O.N. Roofing Ltd inspects both the eaves and rakes for installation of drip edge. J.O.N. Roofing Ltd always suggests the addition of drip edge for a worry-free roof installation.

Chimney Inspection:

Another common area for leaks is chimneys. Though the chimney isn’t necessarily part of the roofing system, it can cause major leaks that are often mistaken for a roof failure. To rule out any possible problems with the chimney, J.O.N. Roofing Ltd visually inspects the chimney to ensure it’s sealed properly and protect against water intrusion.

Pipe Boot Inspection:

The number one cause of leaks on most roofs is the deterioration of the pipe boots that seal around plumbing exhaust vents. Most roofs around Atlanta are roofed with a plastic boot that has a neoprene seal. Due to ultraviolet light, the neoprene dry rots and allows water into the home. J.O.N. Roofing Ltd inspects the seal on all pipe boots.

Roof Ventilation Inspection:

Most homes with roofs over ten years old are improperly ventilated. A proper roof ventilation system is evenly balanced at the eaves and ridge to ensure airflow beneath the decking. Roof vents help keep the attic cooler during summer and prevent condensation buildup in the winter – when cold air from the outside meets the warmer air in your attic. We inspect your roof to make sure there is enough ventilation for your roof size.

Nail Head Inspection:

An uncommon problem that is found on older roofs is improper nailing. Some installers nail too high or too low, and even worse, don’t use enough nails for the shingles they are installing. A more common problem that homeowners notice from the ground is called “nail pops.” Nails can back out during the decking’s expansion and contraction and cause the shingles above to pop up. The nail heads can cause small holes as they rub against the shingles if they are not removed. J.O.N. Roofing Ltd will check for any nail pops and ensure shingles are properly nailed with enough fasteners.

Blistering Inspection:

Asphalt based shingles can sometimes blister in the hot Georgia summer. Blistering is caused mostly by one of two ways. Moisture can get trapped in the shingle during the manufacturing process. When the sun heats the shingle, the water can blister beneath the granules that cover the shingle. Another cause of shingle blistering is improper ventilation that causes the shingles to get too hot, and they start to blister. Blisters themselves are not always a problem; however, the blisters eventually pop, causing the granules that protect the shingle from ultraviolet light to fall off. J.O.N. Roofing Ltd inspects the roof for blistering signs that cannot always be seen from the ground.

Decking Inspection:

J.O.N. Roofing Ltd visually inspects the decking during roof leaks to pinpoint the leak and check for any rotting that may have occurred. Roof decking cannot be fully inspected till the current roofing is removed.

Hail Inspection:

Most home-owners are leery of filing unnecessary claims with their homeowner’s insurance company when it comes to roof damage due to hail. To better help the home-owner in the decision-making process, J.O.N. Roofing Ltd inspects your roof just as an insurance adjuster might. Though adjusters will make their own call on what is and isn’t hail damage, we always do our best to let you know beforehand if the damage is found on your roof.

Valley inspection:

J.O.N. Roofing Ltd inspects all valleys (where the roof planes intersect) for proper installation and ice and water shield use. Heavy rains can cause rushing water to penetrate beneath the shingles, and without proper flashing, water will enter the home.

Shingle Evaluation

Like all things in life, asphalt shingles degrade and wear out over time.
Like asphalt shingles, age, the petroleum or other soluble base of the asphalt evaporates through exposure to heat and washes out through exposure to water from rainfall and snowmelt. This “drying out” of the asphalt causes it to lose its softness, flexibility, and strength progressively. The loss of softness, flexibility, and strength reduces the shingle’s ability to accommodate thermal movements and resist damage from impacts.
The shingles’ ageing and evidence of reduced softness, flexibility, and strength begin with the surface graying and surface hardening of the asphalt. It progresses with cracking in the asphalt, shrinkage of the shingle, especially the tabs, warping or deformation of the shape, granule loss, embrittlement, and breakage. In extreme cases, the asphalt becomes so brittle, not unlike fresh potato chips, that the shingles may become easy to break or shatter. Shingles in this condition are clearly in need of replacement and are well beyond their service life.

Blistering appears as bubbles on the shingles’ surface or small relatively circular cavities that penetrate the asphalt. Blisters are due to the vaporization and expansion of the volatiles, such as kerosene or water, in the asphalt. The vaporization and expansion occur when the shingles are heated by ambient temperatures, the radiant heat of sunshine, and/or excessive heat from a poorly vented attic. When the blisters of the bubble break or are worn away by normal weathering or foot traffic, a cavity is exposed in the asphalt. Blistering usually does not result in immediate loss of water-shedding ability. Still, it reduces the potential service life of the shingle. When the blisters break, small spots of the asphalt and mat are exposed directly to the deteriorating effects of prolonged contact with sunlight and water.

Buckling is the localized heaving of the shingle surface due to the expansion and/or the swelling of the shingle mat combined with the restraint of the shingle mat by the roofing nails, an adjoining shingle, and/or the asphalt sealant. Buckling that extends side to side on a shingle tab immediately restricts the shingle’s water-shedding ability and reduces the potential service life of the shingle because it creates a ridge that may act as a dam that allows water to accumulate and soak into the shingle. Prolonged rainfall onto a shallow slope with buckled shingles may allow penetration of ponding runoff soaks through the shingles. Shingles are not water-tight like a swimming pool membrane. Ponded runoff also exposes the asphalt and mat directly to the deteriorating effects of prolonged contact with water.

Balding is the extensive loss of granules such ch that the underlying asphalt coating is exposed. Balding is the result of normal ageing and weathering of the shingles over the years. Still, it is accelerated by inadequate bonding of the granules to the asphalt coating, repeated scuffing from excessive foot traffic, prolonged wetness, and/or some other manufacturing defect. Balding usually does not result in immediate loss of water-shedding ability. Still, it reduces the shingle’s potential service life because the asphalt is exposed directly to the deteriorating effects of prolonged contact with sunlight and water.

Clawing is downward curling at the corners of the shingles. Clawing commonly occurs when the bottom of the shingle shrinks relative to the top of the shingle. Clawing is increased by the exposure of the bottom side of the shingle to excessive heat from a poorly ventilated attic. Clawing immediately restricts the shingle’s water-shedding ability and reduces the potential service life of the shingle because it creates humps that may act as a dam that allows water to accumulate and soak into the shingle. Prolonged rainfall onto a shallow slope with clawed shingles may allow penetration of ponding runoff soaks through the shingles. Shingles are not water-tight like a swimming pool membrane. Ponded runoff also exposes the asphalt and mat directly to the deteriorating effects of prolonged contact with water.

Cracking of shingles appears as relatively straight line fractures in the shingles. Cracking is due to normal ageing, shrinkage, embrittlement, weathering, and/or deterioration of the shingle over the years. Cracking is specially promoted where the shingle is stretched, and the asphalt is exposed by the bending of the shingles over a ridge, staples, or other discontinuity in the surface of the roof deck

Breakage is the complete dislodging and separation of a portion of shingle due to the shingle mat’s fracturing mat from the normal ageing, embrittlement, weathering and/or deterioration of the shingle over the years. Breakage may be accelerated by heavy foot traffic and/or hand lifting of an already aged, brittle, deteriorated, and weathered shingle. Breakage may result in immediate loss of water-shedding ability. If the breakage is due to the degrading of the shingle material from normal or premature ageing, it has little effect on the potential service life of the shingle because the shingles are already beyond their service life. Corner breakage is usually due to lifting a corner of a brittle shingle with one’s finger or the dog ear-bending at the corner when the bundle of shingles was dropped on its corner.
