I will be finishing the roof on my log cabin tomorrow. I have always installed shingled over ridge vents according to the manufactures instructions,… but on my place, I have a uniquely designed roof system and I wanted my VERY large overhangs vented.
why do they recommend stopping one foot from the interior walls?? what’s the big deal if I go out on to the over hang??
Pogo

My impression is that they're mainly saving you money (though this is an odd thing for a mfgr to do) -- there's no benefit to making the vents longer. But as you say, it looks nicer if they go all the way across.
Your question is confusing.
are you talking about the ridge vent ,or the soffit vents?
The ridge vent. The shingel over style ridge vents. I have 8' over hangs and I want the vented.I met a gin soaked barroom queen in Memphis, She tried to take me up stairs for a ride!
fiberglass shingles on a log home?????
The secret of Zen in two words is, "Not always so"!
When we meet, we say, Namaste'..it means..
The manufactureer recomends the vent continue to the end to ensure that the shingle manufacturers warranty is covered. the way that the ridge and soffit vent system is designed the air flow is directed at the underside of the roof sheathing which is where it is most needed in order to cool the roof and reduce radiant heat from being directed down to the living area.
With that said it would make sense to continue the the vent ot the end, the manufacturer may have recomended that as a minimum ? I don't know fo any reason not to run it out there.
pogo.. continuing the ridge vent to the rake edge gives a much nicer appearance in my estimation..
however... we always stop the slot about 1 ft inside the exterior gable wall.... this is primarily for a belt & suspenders approach to flashing the ends..
also... why do you want to vent your overhang.. ? you certainly can , if you want
in that case ( you said 8' overhang, right ) i'd go ahead and continue the ridge vent to the rake edge, but again.... stop the slot about a foot from the edge..
the only reason is so you can , again, flash the ends..
here's the reasoning.... you have to stop the slot someplace , right.. i mean you do not cut the slot right out thru the rake trim.. it has to stop short of the edge.. one inch... three inches.. 5 inches ?
i think they recommend 12" so the possibility of rain being driven sideways at the ends is diminished to the point of highly impossible...
sounds like you're in snow country.. so make sure your ridge vent has both baffles and an internal filter fabric to keep out fine wind-blown snow..

CRAP! I didnt get the kind with the in side that has netting inside!#@$%&!
It was called "Air hawk" 5' sectionsI met a gin soaked barroom queen in Memphis, She tried to take me up stairs for a ride!
take 'em back & get the good stuff..
i've got a 3-car garage /shop...
when we put the ridge vent on.. some dufus let a small piece of the filter fabric fold back.. at least once every year or two.. that small section allows about 6" of snow to blow in..
mebbe this is the year i'll take it off and redo it.. or
mebbe not..it's just a garage.. but your's is a houseMike Smith Rhode Island : Design / Build / Repair / Restore
