Common Metal Roof Problems – What are the problems with metal roofs
While metal roof systems are one of the most durable and environmentally friendly roofing material available on the market it does come with its fair share of disadvantages. As you probably know, a metal roof is a major initial investment so knowing some of the drawbacks of this roofing material is important. Below are some of the most common cons of a metal paneled roof:
Corrosion
A galvanized steel metal roof is highly susceptible to corrosion and rust over a period of time. You’ll be surprised to learn that the primary cause of rusting and corrosion is water. Yes, oxygen and pollutants in water combined with the moisture create iron oxide otherwise known as rust. Rust eventually eats away at the metal ultimately decreasing its performance. However, most metal panels are covered with water-resistant paint. Before purchasing metal panels you’ll need to inspect the coating of the paint. Next, when someone asks about What are the problems with metal roofs, we will go over failing fastners:
Failing Fasteners or Clips
Fasteners and clips are what holds a metal roof down on the seams. Fasteners and clips are also subject to deterioration largely due to corrosion. Improperly installed and failing fasteners can allow water to enter into the home through open spots. That’s why it’s important to use stainless steel fasteners so you won’t have to worry about the integrity of your metal roof is compromised. When the fasteners or clips fail this can cause the metal panels to expand and contract resulting in the panels lifting.
Easily Scratches
Of course, metal panels are easily scratched. At some point during its lifecycle, you can expect the metal panels to get scuffed or scratched. However, scratches down to the metal can be problematic. Overgrown trees, debris, and even snow can scuff up the surface. In some instances, this can lead to punctures and tears that result in leaks. Metal roofs require regular inspection so that needed repairs can be made before the problems become gets worse. Another common finding to the question what are the problems with metal roofs:
Against Municipality Policies
In some neighborhoods and Homeowner Associations, metal roofs are against jurisdictional policies. That means it can’t be installed or new or existing homes. This is largely due to the fact that metal roofing is often associated with industrial dwellings. A lot of communities aren’t keen on this roofing material because it interferes with the aesthetic value of the area.
Noisiness
Unlike most roofing materials, metal roofs can be noisy especially when it rains or hails. This can be a nuisance for homeowners. Adding additional layers of insulation can solve this problem but it will increase installation costs.
Common Problems with Shingle Roofs
A shingle-style roof is the most popular choice. In fact, nearly four out of every five homes in Alabama uses this type of roofing material. The popularity of shingle roofs can be contributed to its affordability. Since no product is completely perfect to check out some of the drawbacks of installing a shingle roof that homeowners should be aware of:
Granule Loss
Granules provide UV ray protection, contribute to the aesthetic beauty of the shingles and they make shingles fire resistance. While some granule loss should be expected especially when it’s exposed to bad weather, extreme granule loss can is a signal that it’s time for a roof replacement. When your shingles are no longer equipped with enough granule your home will not be protected.
Buckling
Buckling is a moisture-related problem. Buckling or curling shingles leave the structures underneath the roofing material exposed. Moisture can become trapped in the shingles or poor ventilation can lead to moisture which ultimately leads to curling and buckling. When this happens your home will no longer be protected from the rain or snow and you’ll experience frequently leaking.
Missing Shingles
Missing or damaged shingles are perhaps the biggest issue that homeowners tend to incur with this type of roofing material. It can often indicate a major problem. It takes a powerful force to remove shingles from their spots such as strong winds, heavy raining, and snow. Over the course of time shingles become weaken due to poor weather conditions. Also, missing and damaged shingles are the primary cause of roof leaks.
Snow and Ice Damage
Although, shingles are designed to be durable and able to withstand the weather elements snow and ice will eventually wreak havoc on a roof. Why? Snowing and ice melting into water is inevitable. When that happens water seeps in between and under the shingles. In the winter time, water can freezing causing your shingles to lift up or become raised. Unfortunately, this can leave large gaps in your roof allowing water to enter which can cause all kinds of problems for homeowners. The best way to ensure that the weather doesn’t permanently damage your shingles which will result in thousands of dollars in repair is to make sure that you hire a professional to perform routine inspection and maintenance every spring and fall.
Ponding Water
Typically, roofing systems aren’t created to be able to hold water whether it has a flat or slightly sloped surface. Standing water on your roof is a sign that there is a drainage issue. Ignoring this problem can further damage your roof by causing:
- Increases UV exposure to that particular area of the roof
- Causes premature deterioration by compromising the membranes, coating, and flashes
- Challenges the adhesive to hold together shingles
Lack of Efficiency
Heat rays are drawn to shingles especially asphalt shingles. This roofing material holds onto heat and turns transfers it into solar heat into the home. This means that cooling devices such as the air conditioners will work overtime to keep the house and its occupants cool.
