Make
a survey of your attic to get a sense of the working conditions and the
feasibility of the project.
-
Is there a floor in the attic?
If not, you will need some planks or sheets of plywood to provide a safe
work area.
-
Is there adequate lighting
and ventilation? If
not you will need to bring lights into the attic and/or set up a fan.
-
What is the condition of
the roof sheathing? If there are dark spots or rotted sheathing,
your roof has probably suffered water damage and you may want to consider
re-roofing and follow suggestions for strengthening the connection when
you re-roof instead of applying adhesives.
-
Do you have enough access
to get adhesive out to the edges of the roof? The adhesive needs
to be applied all the way out to the edges of the roof because some of
the highest uplift pressures occur near the edges. If you do not
have a steep enough roof pitch to allow access to the edges with a normal
caulk gun, you will need to build a caulk gun extension or use wood blocks
that can be placed near the edges.
-
Does attic insulation obscure
the roof sheathing connection near the eaves or is there insulation between
the rafters or trusses? If there is insulation blocking access
to the eaves or located between the rafters or trusses, you will need to
remove it to gain access to the connection between the sheathing and structural
members.
