Key Factors that Determine the Longevity of a Roof
Homeowners want their roofing systems to protect their homes for as long as possible. Every roof has a life expectancy and requires replacement at some point. How long a roof lasts and how efficiently it performs depends on various factors. Overlooking the aspects that can lead to premature roof failure can prove expensive for homeowners.
Every roof is different, and the knowledge of factors that determine a roof’s longevity can help homeowners take steps to maximize their roof’s service life and plan for roof replacement before a roof is needed.
According to roofing experts, here are the top factors that affect a roof’s lifespan:
Roofing material
Every roofing material has a different life expectancy, and some are more durable than others. The type and quality of the roof material play a key role in determining longevity. Asphalt shingles are the most popular, affordable, and commonly used material, with a lifespan of around 20 years. Metal, concrete, and tile roofs last longer.
Local climate
Repeated exposure to harsh weather conditions has a significant impact on the roof’s performance. Strong winds, hail, sun, and snow take a toll on the roofing system. They can accelerate the deterioration and shorten the roof lifespan if the roof materials are not suited to the climate zone.
Roof slope
The slope, angle, or pitch of the roof determines how well it sheds water. It also impacts the aesthetics and overall look of the house. Low-pitched or flat roofs have a shorter lifespan than high-pitched roofs as they take longer to drain rainwater and snowmelt. Roofing systems with high slopes dry faster and avoid pools of water which cause leaks and damage the roofing materials.
Installation
Premature roof failure and early deterioration are often caused by poor installation. Even the best quality roofing material fails to perform and experiences frequent issues due to installation errors. Always hire an experienced and licensed roofing company to ensure high-quality installation and enjoy a longer lifespan.
Ventilation and insulation
Proper ventilation and adequate insulation add years to the life of a roof. They help the roofing system to withstand the outdoor elements better. Attic vents, fans, and insulation keep it warm in winters and cool in the summer months, lower the utility bills, and prevent ice dam formation. Roofs with insufficient ventilation and insulation suffer from moisture build-up. Moisture is roofing materials’ enemy as it weakens the materials, causes rapid deterioration, and leads to mold and mildew growth.
Roof usage
How a roof is used is one of the factors in determining how long it lasts. Weighty solar panels or other heavy objects and overhanging branches can prove detrimental to a roof. It puts pressure on the roof, damages the roof structure, and clogs the gutters, which leads back to moisture damage mentioned above.
Periodic inspection and maintenance
Ignoring roof maintenance has severe consequences. Regular inspections and upkeep by a reliable roofer keeps the roofing system in excellent shape, increases its lifespan, and shortens the time between replacements. Some roofing manufacturers also demand proof of periodic maintenance by a professional to honor the warranty.
