Reliability Issues with Tile Roofs

Tiles roofs are considered the best option for homeowners living in scorching weather conditions and salty air. In the past, roofing tiles were made from slates, fired clay, or terra cotta products, but nowadays, these tiles are made from molded, colored concrete.

They also come in many shapes and sizes to meet different roofing needs. While roofing tiles are durable, impact-resistant, and stylish, sometimes they can present several setbacks. This article looks at some of the common issues raised by roofing tiles.

Common Tile Roof problems

Sliding and Cracked Tiles

Since roofing tiles are made from clay, they are prone to cracks, significantly if large hailstones or tree branches fall. Also, they might slide off the roofing frames, exposing the underlayment to extremely harmful heat and UV rays from the sun. If this problem is not addressed immediately, it will cause faster deterioration of your roof’s underlayment.

Sometimes this deterioration will begin in less than 90 days, depending on the underlayment materials used. If the underlayment is destroyed, it will allow water to leak through the roof’s protective layer, causing severe damages to your home.


Roofing tiles are hefty, especially the ones made from concrete and clay. Some roofing tiles weigh as much as 950 pounds per square. Therefore, they are likely to overload your roof, exposing you to the risk of a caved-in roof. To avoid such disasters, you have to ensure that the frames of your roof are strong enough to handle the excess weight. Sometimes you will have to do structural reinforcement, which increases the cost of your roof.

Damaged Insulation

When your roofing tiles crack or slide, they expose your roof’s insulation to all kinds of external elements, including excess heat, UV rays, snow, hailstones, and water. This causes the insulation to deteriorate much faster, allowing water to seep through the roof. This water can cause severe damages to your deck and interiors.

Valley Failure

Depending on the kind of elements your roofing tiles are exposed to, their age, and the type of materials used, your roof’s valley might fail, causing severe damages to your house like flooding.

Damaged Soffit and Roof Edges

If your roofing tiles are not installed properly, they will allow water to hide behind the mortar or eave closure at the roof’s edge right at the first row of the tiles. This problem occurs due to the failure by the edge of your roof to drain water properly.
