Most common cause of appliance failure is dust, dirt, and heat retained because of dust and dirt. Most appliances today contain electronics that can be effected by over heating. A cause of heat re-tension is the dust and dirt accumulating on the circuit boards. Another problems with electronics is the sensitivity to high voltage spikes and low voltage. Many say that older appliances last longer since they are built sturdier. Having less electronics is a reason they last longer. If the appliance can have maintenance ( many manufacturers assume they will not be thus they do not provide access for lubrication.) and cleaning the life of an appliance can be lengthen.
Harsh detergents used in excessive amounts is also a cause of product failure. These detergents can effect seals and gaskets.
The life of a roof can vary drastically. The sun light bakes the roofing materials causing them to dry and curl. A roof in the shade can last many years longer than a roof in direct sun light.
The many unknowns and many variable prevents a precise predictability for a budget that has great confidence. If you are handy and can do the work your self will makes a vast difference in cost. Yet allowing for and expecting the unexpected affecting your budget is a must.
