Felt roofs have been a popular choice for UK homeowners for many years. They’re a cost-effective and durable option for flat roofs, garages, and extensions. But how long does a felt roof last, and when should you consider replacing it? In this article, we’ll answer these questions and more.
What is a Felt Roof?
A felt roof is a flat roof covered in layers of bitumen and roofing felt. The felt is made of a mix of cellulose, polyester, and bitumen, which provides strength and durability. Felt roofs are commonly used for garages, extensions, and outbuildings.
How Long Does Roofing Felt Last Under Tiles?
The lifespan of a felt roof can vary depending on several factors. Generally, a felt roof can last anywhere from 10 to 20 years, depending on the quality of the felt, the installation, and maintenance. Some felt roofs can last even longer with proper maintenance and care.
Factors Affecting the Lifespan of a Felt Roof
The quality of the felt is a crucial factor that affects the lifespan of a felt roof. Higher-quality felt tends to last longer, but it also comes with a higher price tag. The installation is another important factor. A well-installed felt roof with proper drainage and flashing can last longer than a poorly installed one.
Maintenance also plays a significant role in the lifespan of a felt roof. Regular inspections and maintenance can prevent minor issues from turning into major problems. Neglecting maintenance can lead to leaks, mold, and other issues that can significantly reduce the lifespan of a felt roof.
When to Replace a Felt Roof
If your felt roof is approaching the end of its lifespan, it’s time to consider replacing it. Signs that your felt roof may need replacing include:
- Leaks
- Visible cracks or tears
- Blisters or bubbles
- Sagging or dipping
- Signs of mold or mildew
It’s also important to consider the age of the roof. If your felt roof is over 15 years old, it’s a good idea to have it inspected by a professional to determine its condition.
Summary
The lifespan of a felt roof can vary, but it can last anywhere from 10 to 20 years with proper installation, maintenance, and care. The quality of the felt, installation, and maintenance all play a significant role in the lifespan of a felt roof.
If your felt roof is showing signs of wear and tear or is approaching the end of its lifespan, it may be time to consider replacing it.
