Will sun alliance cover the damage caused by a defective/blocked gutter rainwater gutters and downpipes. The wallls have been wet and soaking and damp has surfaced in areas affetced by leaks. Any help? how can i go about making a cailm without hitting tinto any of the hitches identified above?

my house has a defective/blocked gutter system and it has damged the Eaves soffit and due to water leakage on to the external brick wall, there are now damp patches in areas and rooms below where the blockages are in the form of damp patches. I know that the gutter may be delined for repair as explained under tear and wear but the blockages in the pipes is not due to tear and wear. The question is Am I entitled to claim for damage to the external wall, which would require some treatment under buildings content insurance?
