HAWAII: 
A REMARKABLE 
PLACE 
TO LIVE-
AND 
A DEMANDING 
PLACE 
FOR 
BUILDINGS 
The same environmental 
conditions that 
make Hawaii so desirable also create one 
of the most demanding climates for 
exterior building materials. 
Unlike regions that experience long periods of cold weather 
or extended dry seasons, Hawaii's buildings are exposed 
to environmental stress throughout the entire year. There 
is no true "off season" for weathering. 
Every day, roofs, 
walls, windows, sealants, gutters, and protective coatings are 
subjected to a continuous combination of sunlight, moisture, 
airborne salts, biological activity, and changing environmental 
conditions.

Over time, performance

a slow process that often remains unnoticed until visible symptoms begin to appear. 
WHAT THIS MEANS FOR PROPERTY OWNERS 
Deterioration 
happens every day. 
It is a continuous process, not a single event. 
Early signs matter. 
Small changes today can prevent major 
issues tomorrow. 
Stewardship protects value. 
Consistent care preserves appearance, 
performance, and structural integrity. 
Prevention is always more 
effective than restoration. 
Planned maintenance costs less and lasts longer. 
Understanding 
Hawaii's climate is the first step toward 
understanding 
why buildings 
age the way they do. 
This knowledge 
empowers 
property 
owners to make 
informed 
decisions, plan ahead, and protect one of 
life's most important 
investments.
