power vents and turtle backs

Have you ever fired a customer? This sounds like a situation where I would walk away from a job as he doesn't want to listen to the expert in his field. What Stephen said explains everything. And $6.00 per foot may or not be to much. Depends on what your overhead is, how long it will actually take to do the job, and how much profit you should be making. Roofing companies that use a per ft. per square price on their pricing generally loose a ton of money before they realize what they have done. The only proper way to bid is a time based estimate. Though that is only my opinion.

Heck, if he would have called our company we charge for repair estimates anymore. Why jump through hoops for things that are less than $2,000.00 generally. Homeowners that want to shop can do that to the jacklegs. Serious people will have no problem paying for your time and expertise.

Good luck in whatever you do.

Good morning.

In general, it's possible to be friendly,polite and business-like-while maintaining controll of the situation. In the scenario you described- it looks like you don't have control of the situation :)

Simply put- you can't let the customer design a roof system that YOU will be held responsible for-via a warranty,implied or otherwise.

Explain to the customer- that with a ridge vent-in order to have it work properly,all other vents( power fans, slant backs, gable end vents etc.) need to be blocked off/eliminated. Only the ridge vent ,balanced by soffit vents should remain.

If you don't follow this procedure- you can get into some freaky situations where things are working backwards-air( and snow,and rain) be sucked IN from ridge vents etc.

Since YOU are going to be responsible for the project- it must be done to YOUR specifications- not the customers. If he won't allow you to do it YOUR way- don't do it at all.

regaurding platic ridge vents:- for many years- MANY-when using ridge vents we used the corrogated plastic type, primarily because they were very un-obtrusive.- within the last year we have had 2 seperate installations "back flow". 2 installations in 20 plus years-is 2 too many-and so now,if using ridge vents we will ONLY use baffled designs. In retrospect- the 2 problem installations were not balanced with soffit vents as well as I would have liked. ALL of our work is old house work-and soffit ballanced intake is not always practical. In retrospect- slant backs may have been a better choice.

Best wishes to you, stephen

I tried that, and he said I wasn't following his "line of thinking.." He seems insistent on leaving those power vents in, since they function the same as turtle vents.. But is that really true? Disconnected, the power vents do the same thing?

I would'nt argue with him sounds like he has the "Know IT All Attitude" Just tell him you will throw in some low profile turtle vents for free and get them old ones off the roof.

Unless of course he has some decking problems due to bad ventilation
