What we get asked about
On the coast these four are further apart than they are inland, because salt and wind create failures that simply do not happen upstate.
One is a construction project. One is an insurance process. One is detective work. And one is the twenty minutes that tells you which of the others you are in, and occasionally earns you a premium discount while it is at it.
Wind and storm damage
The named storms set the design case, but ordinary onshore wind does most of the cumulative damage.
Replacement
A coastal reroof and an inland one are not the same specification, and the differences are all buried by the end of the job.
Leaks and corrosion
Inland roofs leak at details that wore out. Coastal roofs leak at details that dissolved.
Inspections
Twenty minutes that tells you where you stand, and sometimes pays for itself on the insurance premium.
