HOW LONG DO WE EXPECT THINGS TO LAST ?:s.sdcpm.com/age

If an item needs to be replaced before its warranty expires and the manufacturer will not cover the item under the warranty due to damage caused by a tenant, the tenant will be charged the prorated replacement cost to install new item, based on the life expectancy of years shown below

ADHESIVES, CAULK & PAINTS
Surface preparation and paint quality are the most important determinants of paint’s life expectancy. 
Ultraviolet (UV) rays via the sunshine can shorten life expectancy. Additionally, conditions of high humidity indoors and maintained outdoors can affect the lifespan of these components, which is why they should and maintained seasonally

materials they inspect

ROOFING 

The life of a roof depends on local weather conditions, building and design, material quality, and adequate 
maintenance. Hot climates drastically reduce asphalt shingle life. Roofs in areas that experience severe 
weather, such as hail, tornadoes, and/or hurricanes may also experience a shorter-than-normal lifespan 
overall or may incur isolated damage that requires repair in order to ensure the service life of the 
surrounding roofing materials.

SIDINGS, FLASHING & ACCESSORIES 

Outside siding materials typically last a lifetime. Some exterior components may require protection through 
appropriate paints or sealants, as well as regular maintenance. Also, while well-maintained and undamaged 
flashing can last a long time, it is their connections that tend to fail, so seasonal inspection and maintenance 
are strongly recommended.

These life expectancies have been determined through research and testing based on regular recommended maintenance and conditions of 
normal wear and tear, and not extreme weather (or other) conditions, neglect, over-use or abuse. Therefore, they should be used as guidelines only, and not relied upon as guarantees or warranties. 

Note: Life expectancy varies with usage, weather, installation, maintenance and quality of materials. This list should be used only as a general guideline and not as a guarantee or warranty regarding the performance or life expectancy of any appliance, product, system or component.
