How To Waterproof Metal Shed Walls

How to Waterproof a Metal Roof | Liquid Rubber

Unlike timber sheds, the wall material of metal sheds is already waterproof and does a solid job at repelling moisture. However, that doesnt mean metal shed walls are fully waterproof, and it relies on the building being assembled correctly.

Waterproofing challenges on the walls are usually caused by gaps where the panels of the metal shed join together. Larger gaps can be visible as light getting through into the building, but even small gaps are enough for water to get inside.

Begin by inspecting all of the locations where metal panels join together to ensure there are no obvious locations for water leaks. A sealant product such as Gorilla All Conditions Sealant can be used to waterproof locations where the panels join. The sealant acts as a weather barrier and also improves the airtightness of the construction.

An additional step may be to apply a weatherproof coating to all of the walls such as a high-quality metal shed paint. While essential for wooden constructions, the benefit is mainly aesthetic for metal sheds due to their increased durability.

Waterproofing Your Roof Deck With A Tpo Membrane: Pros Cons And Costs

See costs in your areaStart Here Enter Your Zip Code

While having a roof deck is a great way to increase living/entertaining space, one of the biggest issues that many homeowners experience is frequent leaks.

Properly waterproofing a roof deck is often a challenge, because the materials used most frequently, either EPDM rubber, or a Tar/built-up material, do not offer solid protection against leaks.

However, there is a much better, longer lasting alternative: a TPO roofing membrane. Its designed with hot air-welded seams, which makes it impervious to water infiltration.

While a TPO membrane costs more than rubber, you get the benefit of enjoying a leak-free roof deck for years to come. Also, since roof decks are typically small the real difference in price is miniscule and can be as little as $200-400. Therefore it is always preferable to use TPO membrane instead of rubber.

Learn more about TPO membrane costs, as well as pros and costs of installing it on your deck.

Three Types Of Vent Pipes

If you have a metal roof, there are generally three different types of vent pipes used for the different areas on your roof.

  • The first type of pipe that we will discuss is the visible pipe that sticks up from the surface of your roof.
  • You can see it coming out of your shingles and some people refer to this as an exhaust stack.
  • This is commonly used for bathroom fans.
  • The next type of vent pipe that we will discuss is the roof penetration vent. This type of vent penetrates through your roof, but it isnt visible from the ground.
  • A good example of this is a clothes dryer exhaust vent or an attic fan vent. This information applies to both types of vents.
  • The third type of vent pipe is the one that we will be discussing in this article.
  • This type of vent is called a thermal stack or sometimes simply called an exhaust stack.
  • It does not penetrate through your roof, but it still must pass all the way through your attic to get from the equipment on the roof to the outdoors.
  • This is the type of vent that you would see for equipment or air handlers located inside your home most commonly seen coming out of an upper floor bathroom ceiling.

Why Is My Roof Valley Leaking

Liquid Rubber Metal Roof Application

The most common cause of a roof leak where metal flashings are used is shingles that have been improperly cut. When a shingle from either roof intersects and passes over the metal valley flashing it needs to be cut at an angle. The resulting cut is very similar to the angle you might see on the tip of a wood chisel.

Waterproofing a metal shed roof combines two basic forms of weather protectionsealing and painting. Many people recommend that waterproofing should be done immediately after installing a metal shed roof. However, most of the metal shed rood manufacturers tend to include some coatings of weatherproofing. This includes coatings of moisture-resistant oils and moisture-repellents. These waterproofing compounds take some time to gradually, wear-off. Thus, the waterproofing can be put on hold for about 3 to 4 months after installing the roof. Waiting any longer creates the risk of moisture seeping under the upper surface of the metal roof. This creates the problem of internal corrosion that cannot be solved through waterproofing also. For waterproofing your metal shed roof, you can use the following information.

Water penetration can cost homeowners big bucks when the seams of metal roofing sheets have not been sealed properly. Apply butyl tape and waterproof roof caulk to every seam to ensure long-lasting, water-repelling protection. Butyl tape is flexible and strong it is made with rubber and can be reinforced with polyester for added stretch, according to National Coatings. The butyl tape is reinforced by the waterproof caulk, thus preventing moisture from entering under the metal sheets. Top this off with a quality topcoat sealer to reflect heat and decrease the temperature of the metal roof. Adding metal roof overlap sealant could save you a substantial amount of money in energy costs.

  • Sweep the metal roofing sheets of all dirt and debris with a push broom.

  • Lay 6-inch-wide metal roof seam tape, such as butyl tape, over all horizontally lapping end seams. Position the tape with the release backing on the top side. Peel back the release backing to start the application. Position the tape over the center of the seam. Remove the release backing and begin pulling slowly at a 45-degree angle. Press the tape down onto the seam as you pull off the release backing. Tear the tape off at the end of the seam. Roll over the taped seam firmly with a small seam roller to bond it securely. Roll out any wrinkles or bubbles.

    What Are The Best Sealants And Paints To Waterproof Metal Roofs

    Metal roofing sheets will expand and contract with changes in ambient temperature so it is critical the waterproofing paint is elastomeric so it does not crack and fail. Metal roofs after a number of years will show signs of corrosion particularly around cut edges or areas subject to mechanical damage. Corrosion may also have occurred because of ponding of water on flat surfaces caused by poor drainage.

    The metal roof sealant will also need to have anti corrosion properties to withstand heavy industrial or salt water pollution found in industrial and coastal environments. Often when repainting large metal roofs abrasive blast cleaning to remove rust and loosely adhering paint is not practical or economic. Waterproof Metal roof paints should be selected that do not require abrasive blast cleaning.

    The metal roof coating will need to give good adhesion direct to metal, galvanised or corten steel, plastisol and polyester powder coated sheets. A wide choice of colour is also important to blend with the local environment and skyline. Professional contractors select Elastometal an elastomeric anti-corrosion metal roof sealant with a life expectancy of 15 years in C5-M industrial and coastal environments. It is an economic alternative to Noxyde.

    • Loose or missing fasteners
  • Apply Liquid Rubber Seam Tape around vents, flashing and protrusions.
  • Paint Liquid Rubber Waterproof Sealant over seam tape around vents, flashing and protrusions to seal.
  • Apply Liquid Rubber Waterproof Sealant on the entire roof with a brush, roller or sprayer.
  • Allow the sealant to dry between coats.

    Tighten The Roof Panels

    Loosely fitted roof panels will catch wind underneath them and will move and flex in windy conditions.

    This will create vibrations and potentially a lot of noise.

    Ensuring that all roof panels are tightly secured will drastically diminish the amount of noise your metal roof makes when the weather is windy.

    Metal roof panels are fastened into place using roofing screws with washers attached to them.

    Every screw should be tightly screwed in.

    Loose screws will cause problems, including:

    • Allowing water to get underneath the washer, through the screw-hole and into the building.
    • Roofing panels will move more when exposed to the wind, this will create a lot of noise.

    To fix this all you need to do is get up onto the roof with a screwdriver and ensure that every screw is properly tightened so that the washers properly seal the roof from moisture penetration and tightly securing the panels in place to minimize noise.

    Finding The Right Expert

    While applying a roof coating can help to restore your roof and keep both air and water from penetrating the surface, it is important that you hire a qualified professional team that knows the proper way to apply the coating. Otherwise, the problem may remain. The expert crew at Rosies Roofing and Restoration know the importance of applying a 10 ml base coat to fill those cracks and crevices, followed by another 10 ml top coat to protect the roof from dangerous UV rays and weather.

    Damaged Or Degraded Waterproof Membranes

    One of the most common causes of roof leakage is damaged or substandard waterproofing membranes. As membranes wear out over time, they no longer provide the barrier to prevent water intrusion into the concrete. Normally, a new coat of membrane or other waterproofing solutions will have been applied to create a necessary waterproofing barrier.

    Roof leakages might not always be noticeable as cracks in the concrete takes time to develop. This may last for several years before the leak becomes severe enough to cause water damage. Undetected leaks might cause some minor issues that you should take note of:

    • Water stains on walls and ceilings
    • Wet carpets or moisture on flooring
    • Water pooling in the basement
