Planning to tear off and re-roof our 1.5 Car Detached Unfinished Garage. Dimensions are approx 14′ x 21′. It looks to have 3 layers of shingles on it. No Venting anywhere.
A couple questions since I’ve only roofed new work:
- Shoud I install any venting? The garage does not have soffits, which rules out soffit vents. That leaves ridge vent and gable vent. I hate to cut in a gable vent because I don’t feel like messing around trying to match the vinyl siding color, but I will if needed.
- For ridge vent (if needed) do you prefer the roll vent or the ridgid plastic?
- Do you think it would be worthwhile to I spring for a small dumpster ($250)?
Thanks,
Eric

Dumpster might be worthwhile since the garbagemen are gonna hate you after picking up a couple hundred bags of shingles and used decking.
Just add the ridge vent. With no soffets it won't be a great fix, but it will be better than what you have now. I have read mostly negative things on a combination of ridge and cable vents, so I have never tried it.
If the detached garage is unfinnished inside, as most are around here, the ridge vent should work just fine.
1)I'd go for the ridge vent. There is vented drip edge available. I've nver used it, so I can't speak to it's effectiveness or any probems with it.
2)I like the roll vent, but someone will be along to argue about that.
3)What else would you do with about 3000 lbs of trash?

LOL....I should have said the alternative is to haul it myself. Its probably worth the extra $150 not to deal with that though :)
Why would you vent an unfinished building?
It won't fit in a small dumpster.

Around here most folks load the attics with enough junk that it acts like a ceiling. They also install the cheapest 20 yr. shingles they can find. The vented roofs get about 18 to 20 years of shingle life. The unvented get 14 to 15 years max.
That is just emperical from reroofing about 10 garages from 1975 to 1996. Haven't done any since then, so it is more a WAG than anything.
