Slate roof tiles are primarily made of metamorphic rocks, and the mineral composition determines their color and weather properties. For example, chlorite produces green, and hematite has purple tones.
Unlike many other roofing materials, slate tiles are fireproof and can withstand rain, high wind, and heavy snow. These waterproof roofs are perfect for commercial buildings in colder climates.
Although slate roofs are durable, attractive, and long-lasting, they can experience problems over time like any other roofing systems. In this post, we will talk about the typical slate roof problems. Read on!
Missing or Slipped Slates
Misplaced slates are usually due to extreme weather conditions, such as hail and snow, strong winds, and heavy rain. Whether the slates slip out of position or completely removed, it is crucial to fix this problem quickly to avoid compromising the roof. Although it is easy to replace the slate tiles, we recommend hiring a professional roofing expert to get the job done accurately.
Broken Slates
Extreme weather conditions can also result in broken slates. Although harsh weather conditions can break a few slates, if you notice too many broken slates, it is a sign that the roof is becoming soft and more prone to collapse. In such a situation, it is best to hire a professional roofing specialist to inspect the roof and present optimal solutions.
Delamination
The natural material layers the texture of slate tiles. When the slate approaches the end of its life, you will see the layers begin to split apart, a process known as delamination. If you fail to deal with the problem quickly, it can lead to other complicated issues, such as leaks and breakages.
It is important to avoid confusing naturally prominent layers with delamination. Flakes and gaps are common signs of delamination. Because it is not a DIY job to fix the problem, we recommend hiring a professional roofing contractor.
Nail Sickness
Most often, construction companies use nails to fix slates into place. These nails are made from low-quality steel or iron material and prone to rust and decay over time. Nail Sickness is a common term used by professional contractors when multiple nails rust or corrosion on one roof. Hire a professional roofer to diagnose the problem and make any necessary repairs.
Flashing Damage
All types of roofs have a common problem known as flashing damage. Flashing is a sheet made of metal material. It lines and protects certain roof areas from water. Because flashing is made of metal, it is prone to corrosion or rust over time.
When you notice any damages to the flashing, call a professional contractor immediately. Most often, the existing flashing requires replacement with a new one. An experienced roofer can get the job done adequately.
Final Words
Because roofing is relatively expensive, slate is an excellent material with greater durability properties. However, if you notice any signs of weakening with your slate roof, the best course of action is to call a reputable roofing company. Although these roofs are durable, extreme weather conditions can cause problems. It is wise to fix the issues on time to avoid expensive repairs.
