Factors That Determine Roof’s Durability

There are many factors that effect the lifespan of a roof. By examining the following things an expected lifespan of a roof can be determined.

Roofing materials

Asphalt or modified roofs are the most popular option among Philadelphia residents because of their affordable price, long lifespan, durability, and energy efficiency. Metal or tile roofs are preferable if durability is paramount. Metal roofing has quickly become a popular and dependable choice for homeowners looking to update their homes’ roofs, but it is only a viable option for a slope roof.


Mistakes made during installation are the most common reason for an early roof failure. It is important that you hire a dependable roofing company. Although high-quality materials are needed, they won’t ensure a long-lasting roof if you choose an inexperienced roofing crew. It is important to find a company with experience working on your specific type of property and a company that can help with selecting the right materials for your job.

Weather Conditions

Weather will eventually ruin a roof. Exposure to extreme weather accelerates roof deterioration. Frequent, mild hailstorms accelerate asphalt shingle granule loss. Any standing seam metal roof in a snowy or hail-prone area may lose its painted finish faster. Flat roof coatings will degrade under standing water. Even mild weather can diminish a roof’s lifespan. Due to moisture and dryness, cedar shake shingles have a short lifespan. Everyone knows that climate and weather are uncontrollable. Yet, these factors affect roof longevity.


Shingles can bake from the inside out in the hot summer sun if the attic is not kept at a reasonable temperature. The lack of proper ventilation is to blame for this effect, which can result in high energy costs. Excessive heat can also lead to plywood delamination and warping which will cause direct damage to the roof. Moisture damage and mold growth are two further issues that can be fostered by a poorly aired attic. When you schedule your attic or crawl space inspection with a reputable company, you’ll find out if there’s enough airflow.
