If you look up at your roof eves and see water stains or even worse, water damaged wood (dry rot) then your roof is leaking and you need some level of repair done. People have the miss-conception that the dry rot is the problem and if we just replace that the issue goes away, but what they don’t want to understand is that this is just one of the symptoms of a problematic roof.
Of course if there is dry rot in your roof eves the next stage would be to inspect interior dry wall for damage. If the damage has made it that far you are going to want to double check your attic insulation for possible damage. The longer a roof is left leaking, the more damage will be cause and the costlier the repair will be.
