Factors That Affect Your Roof’s Lifespan

Factors That Affect Your Roof’s Lifespan

It’s hard to believe that a roof can last up until 50 years! Some roofs will only need minor repairs and replacements, while others might require complete re-roofing costing property owners thousands of dollars in repairs and replacements! There are a number of factors that can affect roofs lifespan? These include their age, material and how well they have been installed. To ensure your roof remains fully functional, here is a list of factors that affect your roof’s lifespan.

One of the biggest determining factors for roof lifespan is the material that is used No roof is made equally and due to this, materials have different lifespans.

Asphalt shingles are one of the most common types of roofing materials due to their affordability, ease of installation and durability. Asphalt shingles typically last about 20 to 25 years for residential homes.

However, other materials can last upwards of 50 years with the right care and maintenance. Slate, tile, and concrete roofs are believed to be the most long-standing. Similarly, metal roofs are durable, easy to maintain and highly energy efficient.

Roof Angle and Slope

There are generally two categories of roofs: flat and pitched. The slope and angle of your roof can have an effect on how it holds up to various weather elements such as rain and sunlight. 

Flat roofs often have difficulty draining water and create issues where pooling water leads to mould and mildew growth. Not only is this unsightly, but can lead to costly rot and accelerated damages.

Similarly, they also suffer more than sloped roofs when it comes to UV rays. Increased UV exposure increases the risk of fading, UV damage and energy inefficiency. 

Weather and Climate

One thing that all roofs have in common is their constant exposure to inclement weather and other environmental factors. While roofs are designed to protect a property from these elements, over time with repeated exposure they will begin to deteriorate.

Hot climates with heavy rain and extended periods of sunlight can cause asphalt shingles to dry, shrink and crack. Similarly, roofs in colder, snowy regions are prone to accumulations of snow and ice that can cause dangerous weight strain.

Poor Maintenance and Damages

While you can’t control the weather, one thing that is within your power as a homeowner is proper roof maintenance and upkeep. While it may seem like a time-consuming and expensive task, regular cleaning, painting and maintenance are crucial to ensuring your roof stays in top condition and is performing optimally.  

Failing to properly maintain your roof can lengthen the time it takes for you to notice crucial damages, which will end up costing you more in repairs and replacements down the road.

Nearby Trees

Trees are beautiful and provide ample shade, which is why many people opt for planting them on their properties. However, they can also cause significant damage to your roof if too close. 

Strong winds can cause debris to fall and damage the shingles and roof surface. This can lead to holes, tears and leaks over time. Additionally, if leaves and other debris are left to gather, it can create a breeding ground for pests and mould growth.

How To Extend The Life Of Your Roof

One of the best ways to extend the life of your roof is by maintaining it on a regular basis. This means cleaning out gutters, clearing off the debris and checking to see if there are any damages to the surface and shingles. When properly maintained, a roof can last for several decades.

Keep Gutters Clean

One of the most important elements of roof maintenance is keeping your gutters clean. As leaves build up, gutters may become blocked. As such, water is unable to properly drain and flow away from the roof. Ensuring your gutters are clean and unclogged can prolong your roof’s health and reduce the risk of premature repair.

Remove Leaves and Debris

Much like gutters, leaves and other debris on your roof can cause damage over time. Not only do they lead to blocked gutters but can areas that are susceptible to rot and mould growth. Keeping them clean will reduce the risk of accumulating moisture under shingles which can weaken the structure and lead to cracks, holes and leaks.

Regular Pressure Cleaning

Pressure cleaning is an inexpensive and efficient way to clean the surface of your roof. By using high-powered water jets, you can remove dirt, debris and moss that accumulates over time. This improves the look of your roof, will allow for better drainage and provides you with the opportunity to detect minor problems before it is too late.

However, it is important to remember that not all roof materials can withstand traditional pressure cleaners. As such, soft washing has been developed. This method of cleaning ensures that aged and fragile roof tiles are effectively cleaned without the risk of damage.

Regular Painting and Sealing

A final step in regular maintenance is painting and sealing your roof. Simply investing in roof repainting can significantly improve the appearance of your home, while protecting it from mould growth and dirt buildup.
