Let’s face the fact- the house gutter is more than a mere decorative lining and is accountable in collecting rain water whilst diverting the water to keep the building damage free and safe. As a matter of fact without gutters the building would have a rather shorter live, as rainwater falling on them would eventually end up soaking into them.
Precisely, with a clogged gutter the rainwater overflows and finally ends up ruining the facade of the house. Such overflowing water (caused due to the un-cleaned and clogged gutters) eventually manifest itself in forms of leaks in the walls. At worst, such leaking water could even lead to damages in furniture inside the building, or God forbid, short circuits can even occur leading to fire hazards.
If you feel that gutter cleaning is too much work, then it’s always better to consult the experts.
