What is the main problem associated with cementitious siding?

Cementitious siding, commonly made from a mixture of cement, sand, and cellulose fibers, is known for its durability and resistance to various weather conditions. However, one of the significant issues associated with this type of siding is its tendency to crack.

The composition of cementitious siding can lead to cracking due to temperature fluctuations and settling of the building structure. As the material expands and contracts with changes in temperature, or if the building shifts over time, the rigidity of the siding can cause it to fracture. While other siding materials may also experience issues like warping or difficulties in painting, the cracking tendency of cementitious siding is a more prominent concern, particularly because it can compromise the integrity and appearance of the siding, leading to potential long-term maintenance issues.

The other aspects, such as warping or limited color options, are less characteristic of cementitious siding, which generally holds up well under environmental changes and offers many choices in finish and colors, especially compared to some other materials.
