dryer vent
on a 1 floor house,, can a gas dryer be vented through the roof? or MUST it be vented to an exterior wall ?

not a good idea to vent out the roof
the blower on a dryer is not meant to blow up..if some lint gets caught in the vent it will burn the house down...
15' is the max you can legally run a dryer vent...darn designers need to stop putten the dryer in the middle of the house. it belongs on a outside wall or the garage!!!

its not a code issue...but not a good pratice

And stop putting them near the front door also.

The other problem with putting it through the roof is you'll get lint all over the roof and it will stick to the shingles. Some lint will always get through the filter, if the filter were getting 100% of the lint you wouldn't need to ever clean out the vent line.

If you have a longer run, I'd strongly recommend running it in rigid metal duct, use proper duct tape (not the cloth Duck tape) to seal the joints and join the ducts together. Do not use rivets or screws to hold it together because these will trap the lint as it flows by.

Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

Actually we were always taught that the number of elbows installed dictates the allowable length of the vent run. As in the more elbows the shorter the run allowed. But we also were guided by the booklet that came with the dryer. Can be quite a challenge at times.

I agree with the above comments about exiting it through the roof, however it is code compliant to do so. It's more important to keep a shorter run with less elbows then to run longer to get to an outside wall.

Not at all knowledgeable about codes, safety issues, etc.

One time we rented a vacation house where the dryer vent was about two feet from some shrubs. The amount of lint covering (killing) those shrubs left quite an impression.

In my current house the washer, dryer, hook up made it impossible to vent the gas dryer (except through the roof), the previous owner had "illegally" used a style vent made for mobile homes.

Our only realistic option was to re-route the gas line, not too difficult,) move the dryer about 5 feet from the clothes washer, and vent outside.

It has been no problem, no issue, to not have the dryer and washer standing side by side.

thanks for the response,, however we are going to change things around and make sure the dryer is on the outside wall and vented through the wall,, the lesser of turns and run thanks again
