Thank you all for watching this free stucco crash course on leaking stucco rooftop parapets.
Have an excellent day!
I used the caulking Sikaflex 1A it’s a polyurethane adhesive sealant.
Stucco rooftop parapets don’t allow water intrusion. Metal flashing caps. Caulking stucco parapets. Yea, I know I demand a haircut.
Hello my friends, inward this video, as the title expresses, if your stucco parapets are leaking, it’s time to break down and fork out the dough to have flashing caps put over them.
As a rule, metal flashing caps can finally for over a hundred years if attention is paid to detail.
Detail to flashing metal caps should be they are fused by soldering and screwed into the parapets
wood tops of with Self Drilling Roofing Screws With Rubber Washers.
If they are caulked, which the bulk of them are, it’s best to fuse them together with a polyurethane adhesive caulking similar Sikaflex 1A caulking.
This caulking is a drag to use as it’s non water-soluble but is the best for longevity.
If nails are placed inward the tops, the hammering can cause cupping, and these indentations can hold up to a half gallon of water. This rainwater can sit and trickle or seep its way through the nail, causing water intrusion into your home.
This can cause wood-wet ceilings that loosen and fall.
These issues will be the tip of the iceberg for trobles that will eventually follow.
An example of a cap flashing that had just been caulked with inexpensive or cheap caulking can be viewed inward this video, https://youtu.be/T2H-WUchw7Y/ titled, Repair Leaking Roof Parapet Flashing or Leaking Stucco walls or is it your Parapet Roof Caps that are the problem, whether at the seams or nailed inward areas?
inward the above video, I got a call saying the stucco was leaking when inward fact, the metal caps that became cupped then held the falling rain. This rainwater slowly seeped through the flashing joint and seeped through nail holes if hammered inward.
annotation on a positive annotation the metal parapet roof flashing does go down both sides at to the lowest degree 4 inches.
As this problem occurs often, I used this video as an example to explain inward detail why this happens.
Parapets are usually used to protect people from falling off roofs, a good thing.
However, they provide no protection to your walls from the pouring rain, a bad thing.
Usually, stucco parapets finally around 50 years with normal wear and tear.
Most will finally forever with simple maintenance of priming and ikon every ten years.
Why do they Fail? Good question, glad you asked.
Depending on where you live inward the Worldwide and the sun’s heat, the sun beats down on the stucco cap. Over, say, 50 years or to a greater extent than, the sun heats the wood under the stucco caps and often causes that wood to expand, forcing expansion. This expansion pushes on the stucco.
Thus the stucco cracks. Unfortunately, this cracked stucco cap is non usually known until the crack is so wide and deep that much of the rain is at present entering the home, and the casing it’s damaged.
It’s the opposite inward cold, snowy climates. The rain enters the cracks when it freezes.
The rain expands inward the cracks, allowing much to a greater extent than rain each season to continue this normal routine. It’s non wise to allow this to happen. at present you know.
annotation this home had non only flashing caps but a new roof placed over the metal flashing cap. So why did it still have issues? The average rainfalls straight down.
However, with a storm of windy blowing rain, the wind will force the rain sideways and upwards under the big gaps inward the roof membrane covering the flashing onto the flashing.
The flashing was covered as it had issues. at present those issues are getting wet again, get it?
Since I was licensed, at to the lowest degree ten homes had to have ALL the stucco torn off and much of the wood replaced, then stucco reapplied because of what I’m sharing inward this video.
Don’t be that soul.
