What is depreciation in the context of building materials?
Depreciation, in the context of building materials, refers to the gradual decline in value or quality of a material or component over time. It is a natural process influenced by various factors such as wear and tear, exposure to environmental elements, aging, and usage.
Depreciation can affect the functionality, aesthetics, and overall performance of building materials. You must consider depreciation when selecting materials for construction or renovation projects to ensure their longevity and cost-effectiveness in the long term. Regular maintenance and proper care can help mitigate the effects of depreciation and extend the lifespan of building materials.
How does copper depreciate over time?
Copper, unlike some other building materials, does not depreciate in the traditional sense. Instead, it undergoes a natural process called patination, which is the formation of a protective layer on its surface.
Over time, copper develops a greenish or bluish patina due to exposure to air and moisture. This patina actually enhances the durability and aesthetic appeal of copper, as it acts as a barrier against corrosion and further protects the metal. While the initial bright shine of copper may fade, the patina adds character and gives a timeless look to copper roofs or other copper installations.
Therefore, instead of depreciating, copper gradually transforms and gains value through its unique aging process.
Key factors influencing copper’s depreciation
- Exposure to environmental elements: The amount of exposure copper receives to various environmental elements, such as moisture, humidity, sunlight, and pollutants, can affect its depreciation.
- Maintenance and care: The level of maintenance and care given to copper surfaces can significantly impact their depreciation rate. Regular cleaning and inspection can help prevent the accumulation of dirt, debris, and contaminants that may accelerate the aging process.

- Chemical reactions: Certain chemicals or substances that come into contact with copper, such as acidic solutions or salts, can cause accelerated corrosion or degradation, leading to increased depreciation over time.
- Installation quality: The quality of the installation plays a major role in determining how well copper performs and depreciates. Proper installation techniques and adherence to recommended practices can minimize the risk of premature depreciation.
- Climate and geographical location: The climate and geographical location can impact copper’s depreciation rate. Factors like temperature extremes, humidity levels, saltwater exposure (in coastal areas), or high levels of air pollution can affect how quickly copper deteriorates.
- Design considerations: The design and configuration of copper installations can affect their vulnerability to depreciation. Factors such as proper drainage, ventilation, and compatibility with other building materials should be considered to minimize the risk of accelerated depreciation.
The depreciation rate of asphalt shingles
One of the main factors is the quality and type of asphalt shingles used. Higher-quality asphalt shingles with better durability and resistance to environmental factors tend to depreciate at a slower rate compared to lower-quality ones. The climate and weather conditions in the area can also affect the depreciation rate.
Extreme temperatures, excessive sunlight exposure, heavy rain, hail, or strong winds can contribute to the deterioration of asphalt shingles over time. Regular maintenance, such as cleaning debris and inspecting for damage, can help slow down the depreciation process.
However, it is generally expected that asphalt shingles will have a shorter lifespan compared to materials like copper, with an average depreciation rate ranging from 20 to 30 years.
Driving factors behind asphalt shingles depreciation
- Weather exposure: Asphalt shingles are exposed to various weather conditions, including sunlight, rain, snow, and temperature fluctuations. Continuous exposure to these elements can cause the asphalt to degrade over time, leading to accelerated depreciation.
- UV radiation: The ultraviolet (UV) radiation from the sun can cause the asphalt in shingles to break down and lose its flexibility. This can result in cracking, curling, and overall deterioration of the shingles.
- Moisture and water damage: Moisture, either from rain or condensation, can penetrate beneath the shingles and weaken the underlying structure. This can lead to rot, mold growth, and further degradation of the shingles.
- Poor ventilation: Inadequate ventilation in the attic or roof space can trap heat and moisture, creating a favorable environment for the deterioration of asphalt shingles. Proper ventilation is crucial to maintaining the longevity of asphalt shingles.
- Low-quality materials: Lower-quality asphalt shingles may have inferior materials or manufacturing processes, making them more susceptible to depreciation. You must invest in high-quality asphalt shingles to ensure better durability.
- Improper installation: Incorrect installation techniques or poor workmanship can contribute to the premature depreciation of asphalt shingles. This includes issues such as improper nail placement, insufficient sealing, or a lack of proper underlayment.
- Lack of maintenance: Regular maintenance, such as cleaning debris, inspecting for damage, and replacing damaged shingles, is essential to prolonging the lifespan of asphalt shingles. Neglecting maintenance can accelerate the depreciation process.
- Impact damage: Asphalt shingles can be susceptible to damage from falling branches, hailstorms, or other physical impacts. Such impact damage can compromise the integrity of the shingles and lead to faster depreciation.
- Age: Over time, even well-maintained asphalt shingles will naturally depreciate due to general wear and tear. As the shingles age, they may become more brittle, cracked, or discolored, indicating the need for replacement.
How material choice affects property value over time
High-quality and durable materials, such as copper, stone, or premium hardwood, often add value to a property as they offer longevity and timeless aesthetics. These materials are known for their durability and resistance to wear and tear, which can reduce maintenance and replacement costs over the years.
