Tile roofs have existed for thousands of years and are still widely used today. The first known record of tile roofs is in China in 10,000 B.C., and then in the Middle East not long after that. Clay tile used for roofing quickly spread from China and the Middle East to the rest of Asia and Europe.
We are in an age of constant and quick development, but newer isn’t always better. Today, we have a variety of options when it comes to roofing materials. They all serve a purpose, but tile roofing remains one of the best options for people to use in their homes.
Understanding the Lifespan of a Tile Roof
How long does a tile or clay roof last? The lifespan of this type of roof depends on various factors such as the installation quality, underlayment condition, and the region’s extreme weather conditions. However, these roofing materials offer a significantly longer lifespan than other roof types. For example, the clay tile roof lifespan is a whopping 75 to 100 years long while the average lifespan of concrete tiles is 40 to 75 years. Both types of tile roofing offer residents many years of security and comfort. With proper maintenance, one can witness multiple generations of their family growing under the same roof.
Factors Influencing the Average Lifespan of Tile Roofs
Tile is one of the most durable materials utilized on a roof. It is a strong option that can withstand the beatings from hail, the weight of snow, high winds, intense sun exposure, or impacts from tree branches and other things. Ultimately, the total number of years your tile roof will last depends on the following key factors:
Climate
If the tile or concrete roof faces frequent freeze-thaw cycles or other extreme weather like Arizona’s heat, the lifespan tends to shorten.
Installation Quality
Proper installation plays an important role in how long tile roofs last. It is important to have highly qualified roofers for the installation project who can ensure that the roof doesn’t develop leaks or premature damage. These issues will affect the roof’s longevity in the long run.
Clay Tile Roof Slope and Drainage
Going along the lines of installation quality, it is also important that the roof has a proper slope to ensure water does not pool and drains appropriately. This will prevent damaged tiles that contribute to a shorter lifespan.
Foot Traffic
If the roof gets a lot of foot traffic, it will have a shorter lifespan because excessive walking affects the tiles. There is a higher chance of broken or cracked tiles, and such a roof will require more regular maintenance than those that don’t get as much foot traffic.
Storm Damage
Extreme weather conditions like hail or strong winds that cause branches to fall on the roof can cause broken tiles. But hopefully with prompt repairs, the roof’s lifespan won’t be shortened too much.
Ventilation
It is important to ensure that the attic is adequately insulated and ventilated to prevent heat and moisture buildup. Certain harsh weather conditions, like monsoons and heavy rain, can cause a poorly ventilated attic to trap moisture. High levels of unventilated air in a roof can lead to long-term damage, mold growth, and a weakening of the overall roof structure.
Importance of Underlayment in Tile Roofs
Underlayment is an important component of any roof system that will greatly extend its lifespan and prevent long-term damage caused by heavy rains. Underlayment is required according to roofing industry standards, and ensuring it is installed correctly is the key to a long-lasting roof. Here’s why this part of a roof is non-negotiable for many homeowners:
Waterproof Barrier
Like other types of roofing materials, tile roofs are water-shedding and are not fully waterproof. The underlayment is the primary moisture barrier that prevents leaks. Thus, a roofing professional must focus on getting this part of the roof properly installed.
Code Requirement
Arizona building codes require underlayment beneath the main roofing structure as a safety precaution in residential homes.
Protection During Storms
Even the best roofing materials need an extra layer of protection during harsh weather storms like the monsoons that come through Arizona. Underlayment provides backup protection should the roof end up with broken tiles after the storm.
Prolong the Tile Roof Lifespan
A quality underlayment can protect the structure even if the tiles become damaged or shift over time.
Essential for Warranty
Many manufacturers of roofing materials and roof installers won’t honor warranties if underlayment isn’t installed or maintained properly.
Maintenance Tips to Extend Tile Roof Life
With proper maintenance, a tile roof can last the maximum of its lifespan. Here are some valuable maintenance tips from our roofing professionals:
- Schedule annual maintenance inspections that check for broken or damaged tiles
- Clean the gutters and roof regularly to prevent any water from pooling
- Avoid walking on the roof, leaving inspections and cleanings to the roofing professionals
- Make sure to address minor repairs before they turn into bigger problems
- Do not delay replacing underlayment when the time calls for it
Regular maintenance of the roof will go a long way to helping you enjoy a safe and protected home without spending money on costly repairs. If it’s been a while since your tile roof received a once-over, get in touch with our professionals today.
When to Consider Tile Roof Replacement
If your home is pretty old, it is likely due to a new roof. After all, everything requires replacement eventually. Here are some signs to watch out for when you’re considering replacing your roof:
- There is visible sagging, water leaks, and multiple broken or cracked tiles
- The underlayment is poor in condition, causing water to seep through
- Clay tiles shifting or out of place
- The roof is over 50 years old and hasn’t received adequate maintenance
- The need for costly repairs is starting to increase in frequency
