Ridge Vent leak


We recently moved in our new place. The roof is asphalt shingle and is 14 years old. During heavy rains and wind last week, we saw water trickling down the ridge vent in the attic. We received a quote from a contractor to cap the ridge vent and instal 5 new square vents. Would capping the vents and installing the square vents solve our problem and also ventilate the roof enough? It also snows in winter here. Any recommendations would be appreciated.

Ridge Vent leak


I wonder why ridge vents are leaking. But yes. It can be re-ridged and go with the others. There is a formula for amout of vents you need according to cubic feet of attic space. Make sure your roofer follows this spec.

Ridge Vent leak


Why not replace the ridge vent with one of the more screening and weatherproof options?

If it's three tab shingles then 14 years is about all your going to get out of them, there would be no since just doing a fix when your due for a new roof. If one if the caps is cracked where the two pieces come together it's going to leak.

Even if it is one of those "30-year" roofs...you are nearing its projected lifespan as well.

These guys probably know their roof is old. Some new ridge caps or vents will probably buy them a few more years if they can't afford a new roof right now.

I'd wager that you have an improperly installed ridge vent. Slot cut too wide, torn ridge caps, improper nailing, etc. I prefer ridge vent over box vents in most instances. It would be wise to figure out what the problem really is before solving it.

Ridge Vent leak


There are a couple of things you can do:

1. Remove the existing ridge vent and install a newer version. The older style type might be letting wind-driven rain in in a way a newer one (with side baffles) wouldn't.

2. The way you can determine sufficient ventilation in pulling off the old ridge vent, capping, and going with new pod vents goes like this: a standard pod vent will allow 50 square inches of exhaust ventilation. Essentially, you want 1 square inch of exhaust ventilation (plus one square inch of intake ventilation at the soffits) for every TWO SQUARE FEET of attic floor space. If your contractor is any good at what they're doing, they ought to be able to show you the calculation for ventilation.

3. Try the COBRA Snow Country Ridge vent from GAF if you get snow.
