First thing in line are probably walls, or flooring, or a door, or windows replacement. Seldom does anyone think of the roof gutter. It may not be found in the basic house drawings, and yet it is an essential part of the house.
The roof gutter has only one purpose: to manage the rainwater that falls on the roof, and directs it to a desirable location. By keeping the rainwater away, the foundation of the house is protected and erosion is reduced. Leakages into the basement and crawlspaces are avoided, and paint finishes are preserved. Another bonus: it is easier to collect rainwater from the gutter system for a later use.
Without a roof gutter, rainwater will splash down the ground in all directions, and this will cause many problems and inconvenience. Rainwater splashing on your wooden deck invites termite infiltration. Termites love to hang around and multiply on moist wood.

Rainwater that falls from the roof and lands in your head can be a big problem. Nobody likes this nasty experience.
A good gutter system in the house can minimize the cost of your home renovation. This is because, given the benefits of having a roof gutter, the structure is protected and may need little else to repair.

Some roof specialists provide a system that filters the leaves and other debris that accumulate on the roof over time. This will make it easier for the water to pass through.
Gutters lead the water to the base of the house and away from it by means of a downspout. This is part of the gutter system.
So, yes, and definitely, there is a need of installing a gutter system on your roof.
