Roof replacement presents a substantial financial commitment for homeowners. However, the expenses associated with a full shingle roof replacement have been steadily rising in recent years, showing no signs of slowing down. Furthermore, the quality of asphalt shingles has deteriorated, resulting in a decrease in the lifespan of roofs. It is crucial to delve into the reasons behind the escalating costs of shingle roof replacements and the decline in shingle quality. According to HomeAdvisor, the average cost of a new roof installation in the United States ranges from $9081 to $12,444. This increase is primarily driven by the rising costs of materials and labor. Raw materials like asphalt, oil, and steel have become more expensive over time, leading to higher prices for shingle manufacturers. These increased costs are then passed on to homeowners when they purchase shingles for their roof replacements. Additionally, the demand for roofing services has surged, resulting in elevated prices. Angi’s List highlights that the upsurge in home improvement spending has caused a shortage of skilled labor, intensifying the demand for roofing services and subsequently driving up costs. The deterioration in asphalt shingle quality is another factor contributing to the reduced lifespan of roofs. Manufacturers have been reducing the amount of asphalt in shingles to cut costs, making them thinner and more vulnerable to damage from the elements. Consumer Reports notes that modern shingles are thinner and less durable than those produced in the past, making them more susceptible to weather-related damage. Moreover, the decline in the quality of the fiberglass mat used in shingles has also played a role in reducing their durability. The fiberglass mat serves as the foundation of the shingle, and a subpar mat can lead to shingles that are more prone to damage. The Spruce explains that the quality of the fiberglass mat significantly impacts the shingle’s durability, with lower-quality mats increasing the risk of premature cracking and splitting, thereby shortening the shingle’s lifespan. In conclusion, the increasing cost of complete shingle roof replacements can be attributed to the rising costs of materials and labor. However, the diminishing quality of asphalt shingles has also contributed to the decrease in roof lifespan. Homeowners should consider these factors when contemplating a roof replacement, as the era of 25-30-year-old roofs is now a thing of the past.
