Roof vents

The Family Handyman - - DIY ESSENTIALS -

Check for cracked hous­ings on plas­tic roof vents and bro­ken seams on metal ones. You might be tempted to throw caulk at the prob­lem, but that so­lu­tion won’t last long. There’s re­ally no fix other than re­plac­ing the dam­aged vents. Also look for pulled or miss­ing nails at the base’s bot­tom edge. Re­place them with rub­ber-wash­ered screws.

In most cases, you can re­move nails un­der the shin­gles on both sides of the vent to pull it free. There will be nails across the top of the vent too. Usu­ally you can also work those loose with­out re­mov­ing shin­gles. Screw the bot­tom into place with rub­ber-wash­ered screws. Squeeze out a bead of caulk be­neath the shin­gles on both sides of the vent to hold the shin­gles down and to add a wa­ter bar­rier. That’s much eas­ier than re-nail­ing the shin­gles.

SO­LU­TION: Re­place the old vent. If you’re care­ful, you won’t have to re­move any shin­gles to slip out the old one and slide the new one into place.

PROB­LEM: Plas­tic roof vents can crack and leak. Duct tape is not the so­lu­tion this time!
