You probably can’t wait to install a thatched roof for your home, but how long does a thatched roof last? Durability and longevity might seem unimportant until you start budgeting for a roof replacement five years after the new installation.
Thatched roofs are aesthetically appealing, and they offer proper insulation. The roofing material can last for 15-40 years with reasonable care and maintenance. However, homeowners should remember to repair or replace the roof after 10-15 years.
While you can’t wait to hire installers to fix your thatched roof, you first need to know its pros and cons before buying it. Also, the roofing material lasts longer if well maintained, so we will mention the best ways to keep it.
Let us get started.
What Is A Thatched Roof?
Thatched roofs were standard in traditional houses, but homeowners still use them today. A thatched roof installer uses dry vegetation like straw, water reed, or sedge to create the covering.
Although the roofing style was familiar, homeowners in developed countries are slowly going back to thatched roofing. The material is aesthetically appealing, environmentally friendly, and durable.
Water reed thatched roofs have the highest durability because this roof can last for up to 60 years. Besides, it has fewer maintenance costs and can be shaped differently during installation for more aesthetics.
The roof’s performance depends on your area’s climatic condition, shape and design, and pitch. The thatched roof does not absorb much water with proper maintenance, so you won’t get any water damage.
Although you will be more interested to know thatched roof’s advantages, ensure you also study the cons. For example, poor roofing material installation can lead to wind accidents. Reeds are lightweight and can easily be carried away by the wind.
Advantages of Thatched Roofs
Before asking ‘how much does a thatched roof last,’ first find out the advantages. The pros help you make a better decision on whether the roof is worth your coins. Some of the benefits are;
1. Environmentally Friendly
Thatched roofs are from dried reed, and they don’t require chemicals to grow or a machine to harvest. Besides, the roofing material mainly grows in the rural areas, meaning the harvesting time creates jobs for the people.
When it ages, thatch quickly decomposes, becoming good manure. The homeowners can also feed old thatch to animals instead of throwing it away. The roof’s durability also contributes to environmental friendliness.
Homeowners with thatched roofs enjoy good insulation. The roofing material prevents energy exchange in and out of the house, maintaining the correct room temperatures. Therefore, the HVAC system has less work, meaning fewer energy bills. Energy efficiency also increases the home’s comfort.
3. Aesthetically Appealing
One of the significant reasons you want a thatched roof is its aesthetics. The roof is simple in design but makes a huge statement. Alternatively, you can choose different pitches and installation methods to add character to your home.
Thatch has a high resistance to some climatic conditions, hence it has high durability. However, although it has a long lifespan, homeowners should maintain it by replacing any rotting parts and keeping animals away from the house.
5. Ages like Fine Wine
While other roofing materials will age by rusting or fading, thatch shapes into natural forms that increase aesthetics as it ages. The reeds could change into a darker color that blends well with the walls.
