Balcony systems are included as part of the building envelope primarily as a grouping of wall access projects; when you have to access the building’s exterior via swing stage, it makes sense to address as many issues as possible, in order to minimize access costs. Balconies are also a significant source of water penetration at many buildings, and their repair should coincide with other wall repair work. How they are protected and maintained will impact the risk of water penetration events over a building’s lifetime.

Concrete balconies deteriorate naturally due to a reaction with atmospheric carbon dioxide. Protecting them from excessive exposure to water is important in limiting concrete deterioration and associated repair costs.  Planning to add protective systems is a good investment.

Balcony railing systems are anticipated to have a 30 or 40 year life as aluminum does not readily corrode.  However in the case of poorly assembled or designed railing systems, retrofit projects may be required in order to achieve this anticipated lifespan.  Retrofits, rather than replacements, will improve the financial health of the reserve fund.

Most high-rise roof systems are assumed to have a 25-year life.  This can be extended significantly with proper maintenance.  Most roofs can have their lives extended significantly utilizing local repairs including regular inspections as the roofs approach the end of their planned service life.

Asphalt shingle roof systems lives depend significantly on the performance of the attic below.  Poor ventilation or moisture issues will significantly reduce the life of asphalt shingles. Buying 25 year shingles that only lasts 12 years because of attic ventilation problems is not a good investment.
