As a former roofer I would suspect condensation dripping from a non-insulated roof underside where the actual beams are, if the plywood is actually exposed to your view, this may very well be where your problem lies. If when your roof was installed, it may very well be you had a handyman and not a certified roofer install your roof, which in turn would render you an improperly installed roof, you did not indicate whether this is a flat roof or shingle roof, however a coat a flashing cements by a brand called Karnak or metal flashing may indeed help your situation.

You might be getting what they call freezeback. Ask your roofer if he installed "ice shield". Guaranteed he didn't. Ice shield is a stcky backed (tar) membrane that doesn't allow ice to crawl under your shingles and leak into your house. This happens when your gutter freezes and ice builds. Code is you should have enough ice shield to project into your house at 3ft. So you should have 2 rows or around 6ft of ice shield installed from the end of your roof up and then the rest is tar or felt paper. This is installed almost the same as felt paper. You jus peel the back of it and it sticks all by itself. Probably easier to install than paper. The cost would be about 90 bucks a roll.

It sounds as if the roofer did not install the vapor barrier, (rolled shiney black tar paper, then the rolled black felt paper ) under your shindles.

You must conact your roofer and complain... COMPLAIN.. it sounds like you have a leak and the installers have allowed moistere to get under the roofing materials...!!!

Basically water expands when it freezes (ice cube tray.. over filled ) so if there's any kind of leak the water penetrates.. feezes allowing it to migrate up under the materials and then as the warm air from inside the attic causes the ice to then melt. I'd call and find out what the deal is.. especially if this has been going on SINCE the new roof was installed....

good luck

We have a mold and mildew smell coming from our air condtioner in our fifth wheel,what can we do about it? Everytime we use the air conditioner it smells bad. We tried sraying lysol into the intake but...


You can shut off breaker to the unit and go on roof and remove cover to do a visual check under cover in drip pan etc, as well as shine a flashlight in where filter at ceiling goes to look at coils and fins (way up inside) for any sign of mold etc. The hard part here is that I am going to assume it is a ducted system, and we can't be sure the mold smell isn't coming from the ductwork. Hopefully you"ll see something when cover on roof is removed.

My fan shakes and wobbles even on low and it also seems to by loose where it mounts to the ceiling. What do I need to do.


I imagine you have a ceiling fan hanging from the roof?? These fans are mounted on a hook which is loose from the roof. This is to prevent any vibration being transfered to the ceiling itself. Generally, there is a domed cover to hide the hook and associated wiring to the fan at the point of attachment to the ceiling. This dome should have a gap of a couple of millimeters away from the roof. If the fan is vibrating, it can also occur because one of the blades may be loose or dislodged. Try tightening up any screws holding the blades to the motor body or refitting the blades. If this doesnt help, you may need to remove all the blased and weight them seperately. 1 may have "thrown" a balance weight and is now unbalanced. Much like an unbalanced car wheel vibrates. All the blades should weigh the same. I used to fix these by supergluing metal washers to the top side of the lightest blades to make it up the weight of the heaviest. It works but someone may have a better idea...

Stops blowing air


remove cover at ceiling so you can see in at fins and see if they are frosting up bad. If they are, I suspect during AC installation, they didn't open up ducts on discharge properly and air flow is restricted, which will cause freeze up, especially if low flow from discharge ducts. I'm assuming it is a ducted system. You may have to remove or drop down entire ceiling assy, to see if the ducts into ceiling have any blockage. Sometimes they don't cut rubber roof material back far enough, or misaligned ducts and cause restricted flow to ceiling vents, which will cause unit to frost up, which kicks out compressor until frost is melted, then compressor kicks back in and cooling happens again.

My walk-in's ceiling panel is dripping


The coil in the conditioned space is called the evaporator.
If the water droplets are forming on the ceiling around the evap, it is due, most likely, to the defrost cycle being too long.
Defrost cycle: compressor stops, evap fans stop, electric heaters in the evap come on to clear any ice/ frost on evap fins/ coil.
The ice/ frost melts and some of it turns into vapor. As it hits the cold ceiling surface, it condensates into water droplets. Defrost cycle could be too long. Usually 4 time aday and no longer than 30 minutes should be enough unless there is high humidity.
There could be another cause.
Normally, after a defrost cycle terminates, the evap fans do not come on, due to a delay control. This prevents circulating warm are due to the heaters. The compressor comes on and cools the evap down to, usually 20 degrees or so, and then the fans come on. What could be happening is, the fans are coming on too early and blowing the water driplet off the evap and onto the back wall of the unit.
A third item, is to be sure that the condensate drain is "P" trapped. The prevents warm, outside air from being drawn in and causing exess frost build up, thus excess water and vapor.

Good luck and hope this helps

Wet line on ceiling between 2 air vents that runs about 8 feet


I would begin by inspecting and repairing the flashing around each vent. Generally you can use a caulk gun with a tube of roof cement for this quick repair.

Whirlpool refrigerator stop cold but frosting bad


Hello Catherine Fu,
Welcome

You said, you got this whirlpool double door refrigerator for 4 years. cost me about 1.5k. the second year, right after warranty, the main brain is down-the light panel in the refrigerator is off. whirlpool tech told me to replace it will cost me 500, so you decide not to do it. Now you have bad frosting issue for 6 month. Inside the Refrigerator, the water keep on dripping on side wall and glass drawer ceiling. In the freezer, frosting all over each drawer, and the bottom drawer has too many frosting and ice that i can hardly close the door. Last night, the refrigerator section just don't get cold anymore, it shuts up by itself.
Help!! It is an very expensive refrigerator and ONLY 4 years old .


First,I think you need to have a new tech.
It sounds like you have either an air leak allowing out side air in and this causes the icing.
Or you may need some freon (coolant gas) .
If your freon pressure is low it can ice up.
Did that tech that was there check for a freon leak and also check the pressure of the freon in the lines???
You need to call a different tech and let him see what's happening.
Some company that is reliable!

Let me know what they do for you.
God bless, Huuum

please remember to leave a rating.
