plant roots posses root hairs which anchor the plant in soil and their major function is to absorb water and nutrients from soil. if there will be waxy cuticle on there epidermis it will be hard for roots to absorb nutrients and water from soil hence plant without water and nutrients will die.
Think about the function of a root, its to absorb water and nutrient - what does the waxy cuticle stop the loss of?

Epidermal cells of roots are not coated with cuticle because cuticle would prevent roots from absorbing water and minerals.
The cuticle is water proof - the root epidermis needs to be semi-permiable for osmosis to occur
Roots take in water and the stem tries to conserve water. That simple.
As in you this is called the epidermis. On top of that is a waxy cuticle that further protects the plant and also retains moister.
Leaves have a waxy layer on top of their epidermis layer called the cuticle. This waxy surface protects the leaves from sunburn, dessication (drying out) and reduces attacks by fungi, bacteria, virus particles and insects.
I belive it's called the Cuticle and it's thinner.
It is called the Epidermis
The Waxy cuticle in a plant is situated above the upper epidermis. The waxy cuticle provides protection to the epidermis. But the main task of the waxy cuticle is to increase and decrease transpiration of water in a plant accordingly. The cuticle helps in cuticular transpiration of plants and sometimes you can find a shiny cuticle in a plant in order to reflect back the sunlight and prevent transpiration. Having a shiny cuticle is one of the adaptations of a plant to reduce transpiration. These are the 2 main functions of a cuticle.

The waxy coating the epidermis in a plant secretes is called a cuticle.
It restricts cuticular transpiration
A waxy covering of the plant that helps the plant retard moister loss.
The waxy leayer of leaves is called the "epidermis". It forms the boundary separating the plant's inner cells from the external world. The epidermis serves several functions: protection against water loss, regulation of gas exchange, secretion of metabolic compounds, and (in some species) absorption of water. The epidermis is usually transparent (epidermal cells lack chlorophyll) and coated on the outer side with a waxy cuticle that prevents water loss. The cuticle is in some cases thinner on the lower epidermis than on the upper epidermis, and is thicker on leaves from dry climates as compared with those from wet climates.

The waxy translucent layer is the cuticle the upper epidermis is where most photosynthesis occurs and the lower epidermis where very little photosynthesis occurs
