Keeping the gutter system maintained helps prevent major problems.
Watch out for overflowing gutters, out of alignment of gutters with downpipes, leaky gutters, dampness on walls and ceilings, all these are preventable and if caught sooner than later can prevent bigger jobs and more expensive repairs.
Broken roof tiles can also be a problem, and leaves, nesting materials and dirt build up, all of which can cause the rain water to overflow or drip in places they shouldn't be. Heavy rain and heavy snowfall can put a strain on the gutters and may need repairs carrying out.
If one section of the guttering is damaged, it can usually be repaired without a full gutter replacement.
