The exterior walls of the building are a metal stud exterior wall system

with a brick veneer. While they appear in good condition, where they

may be opened up during renovations, the condition of the cavity wall

insulation and exterior waterproofing membrane should be checked and

repaired/replaced, if needed.

The main roofs are an asphalt shingle that seem in fair condition and

probably have useful life remaining. These should stay until

replacement is needed (guessing at about 10 years or so). When

replacement is called for, we would recommend a photovoltaic shingle

be installed on the south facing slopes of the roofs. This will produce

electricity for the building and reduce its energy consumption. Also
Existing opening in exterior wall Lower flat roofs showing ponding
recommended during renovations, whenever the roof structure is

exposed, is to install a spray foam insulation at the underside of the

existing roofs. This will further improve their energy efficiency.

The lower flat roofs seem in worse condition and should probably be

replaced. There is evidence of severe ponding in downpours that

should be fixed. Two of these roofs are complicated by multiple

penetrations and curbs from HVAC equipment. It is recommended to

replace the roofs with a similar product (looks like a TPO material),

ensuring at least a 60-mil thickness and an R-30 rigid insulation below.

All flashings and terminations should also be replaced at this time.
