Andrew - 

 

This might be what you're looking for since it's designed to be permanently
mounted:

Hi Andrew,

 

Good topic! We typically use a ridge anchor like this:

On existing comp roofs one option is to gently peel the top shingle off and
then fasten the anchor down. After work is complete you can remove the
anchor (often times with great difficulty) seal the holes, and then replace
the top shingle after the work is complete. Another common method is to
simply use some good sealant and fasten it to the rafters right through the
top of the cap. Then, the anchors can permanently be left in place for
future maintenance work if aesthetics isn't a concern. 

 

I'm thinking that you've already thought about this option?

Has anyone found roof anchors that are designed to span the ridge cap on
existing composition shingle roofs?  We have a number of different types of
anchors that we attach on the north side of the roof with screws into the
truss but that invariably leaves the issues that result from running a rope
over the peak: crushing the ridge cap, damaging the ridge cap shingles, wear
on the rope, etc...  We use the "carpet or cardboard on the ridge" method
but it is imperfect.  We have one anchor that is designed to span the ridge
on unfinished roofs with a 6" leather strap but it won't span most ridge
caps.  I'm looking at the Guardian Fall Protection catalog - which is
awesome - but it doesn't have anything for this particular application.

Thoughts?
