Adding Ridge Vents to a Roof?

Is it possible to add ridge vents to a roof w/o hurting or replacing the other shingles?

Our shingles are basically black, so I think matching it with an added roof/ridge vent wouldn't be hard IF the top section of a roof can be replaced with ridge vents/

The house/roof is 6 years old.

Go to Home Depot and buy Cobra Vent ridge vent. It comes in 20' and 50' rolls. You will need to remove the exsting ridge shingles and cut back the roof sheathing from the ridge, install the Cobra Vent, and a new shingle ridge the same color as your roof over the ridge vent. This stuff works great and you can't even see it after it's installed. Or you can take the easy way and install that aluminum ridge venting that looks like hell and leaks.

I thought it could be done to an existing roof!

It just seems like it would really cool things off. Our bonus room is hot, and our living room and master bedroom have vaulted ceilings, etc, and I think the house could benefit from having this put on.. and save on the cooling bill.

Thanks!

What Craig is describing is for an existing roof. If you take the ridge cap off extra carefully, you may be able to reuse 'em, with the top row of shingles on each side that came off to make room for the vent in reserve.

You need good air flow from the soffits to the peak between the bottom of the roof deck and the insulation or it won't do anything. If your bonus room is an attic, ridge vent won't help much with the heat in the room, thicker insulation will, if you have the space. The heat is a radiant heat from the hot roof, not a convected heat.

THe soffits do have the vents, so it should work some, right?
