7 Reasons Why You Need To Waterproof A Metal Roof – Today, more homeowners are looking for environmentally-friendly options when it comes to home improvement projects. Many people are finding the benefits of metal roofs – they are very durable, last a long time, and can save you money on cooling costs.
While they offer all these advantages, there is one drawback that is often associated with them: the need for waterproofing. Because they are not susceptible to damage from rot or mildew, many homeowners choose metal roofs over traditional ones that require constant maintenance and expensive repairs.
However, most metal roofing systems do require some form of waterproofing to protect them from rain leaks. If you have chosen a metal roof as your new exterior covering, here 7 good reasons why you need a waterproof metal roof:
When it rains, water gathers on your roof and if there are any holes or cracks in the roofing material, the rain will leak inside your home causing damage to furniture, appliances, and other personal belongings. It is important to make sure that the rooftop is trapped securely under an impermeable layer of waterproofing protection so that leaks do not occur. Waterproofing also protects against wind-driven rain which can cause leaks around chimneys, vents, skylights, and dormers.
One of the most common signs that a house has water damage due to leakage is mold or mildew growth. This is especially true in damp areas where warmer temperatures encourage mold spores to multiply very fast – think drywall behind showers, windows and doorframes.
Waterproofing is also required to protect your roof from moisture damage caused by humidity in the air as well as condensation such as on cold days when warm, moist air inside a home meets with chilly surfaces such as windows or metal roofs.
Over time, mold and mildew might form if the water stays on the surface of the metal long enough for it to seep into its pores and cracks. This may lead to rust and corrosion and shorten the lifespan of your metal roof.
In addition to decreasing the quality of your roof, this problem can be very expensive to repair due to high replacement costs – especially for homes with skylights that cannot be removed without taking down the entire roof.
Waterproofing is required when you install skylights, vent pipes, plumbing stacks, and chimneys in your metal roof; otherwise, rust or corrosion may occur because moisture can enter the area between the metal sheets. Any openings in your roof should be sealed with a special sealant to prevent wind-driven rain from entering under the shingles.
If any of these areas are not properly waterproofed, there is also the risk that gutter systems will not drain properly because high levels of water can collect on parts of your rooftop where they are not supposed to be. This means that gutters could overflow causing damage to both your home and foundation, which would probably require costly repairs.
Waterproofing is required to protect the metal sheet from blistering or bubbling. This occurs when there are areas on your roof where moisture accumulates and evaporates more quickly than in other areas – for example, near a chimney.
In cases of moisture damage due to high humidity, it may take years before you notice problems with bubbling or blistering because bubbles first become visible on the surface after the material has been exposed to extreme temperature changes such as those experienced. As this problem worsens over time, leaks will occur and waterproofing at that stage will be too late to prevent extensive damage caused by rot and rust.
While most metal roofing manufacturers guarantee their product with a warranty for up to 30 years, this is only true if your metal roof has been properly installed and waterproofed.
Doing it yourself may not be a good option because leaking can occur long before you realize there’s a problem or even notice the damage on your rooftop.
If you install waterproofing on your own, you will end up spending more money because leaks won’t be prevented and repairs will still need to be done by trained professionals to ensure that everything is sealed properly – which means that ultimately, contracting all work to one company or doing it yourself will cost much less than hiring different contractors overtime for separate installation and repair projects.
Asbestos was commonly used in fireproof insulation before it was banned in many countries because of its potential health risks when disturbed by workers during installation or removal – especially if not done properly – which can lead to lung problems down the road such as mesothelioma.
Waterproofing is required when metal sheets are installed over an existing asphalt shingle roof because asbestos could be present in these materials. You should always have a contractor test your roof to determine whether or not it contains asbestos shingles before beginning any type of work.
If asbestos is present, you must hire a qualified company that knows how to handle this problem correctly and safely without endangering the health of workers or releasing fibers into the environment – which may then enter your home through the air.
Asbestos fibers are particularly dangerous if inhaled because they are very thin – around 5 to 100 times thinner than a human hair.
If you have an asbestos metal roof, waterproofing should be done by a specialist who can efficiently remove all shingles with asbestos before replacing them with new metal sheets. Otherwise, the risk of contracting serious lung disease is high if you do not take proper precautions when working on your rooftop or when performing any type of maintenance that disturbs existing materials.
Waterproofing your metal roof is a basic element of proper maintenance that can help extend the life of your metal roof and prevent expensive repairs.
No matter how durable or well constructed your metal roof may be, wet conditions and harsh climates that expose it to high humidity and extreme temperature variations – especially if your roof is not properly waterproofed – can result in leaks and damage caused by rust and rot which should be addressed right away before they worsen over time.
