Installation, Replacement, & Repairs Pros

You can install metal roofs over an existing one with no tearing off of the shingles as long as you follow the local building codes. While it is preferred to remove the shingles, tearing them off is so messy and tends to increase the cost of the job.

The main challenge with such installations is that they tend to trap water vapor. If it gets trapped between the old roof and the new metal roofing, the moisture will build up and lead to rot and mold. However, roofing contractors may install a vented metal roof to eliminate these potential problems. Or, when you install a new metal roof on top of the furring strip, it will raise the metal roof and deliver a ventilation air pocket between the layers. However, before you install the roofs on top of the shingles, make sure you consult the local building codes. Some jurisdictions need full tearing off whenever you are installing a new roof.

There is a lot of misconception that metal roofs make more noise when hail and rain fall on them. The truth of the matter is that when you install metal roofs properly, they are not noisier than the other roofs. Metal roofs are typically installed on top of a solid substrate. To add on this, the insulation and attic provide a barrier to sound. From the interior living spaces, the inhabitants will rarely notice increases in sound levels when installing metal roofing.

Some people will tell you that metal roofs tend to attract lightning. However, this argument does not have any statistical backing or facts. The truth of the matter is that metal roofs don’t increase the risk of lightning strike in any way. In fact, when lightning happens to strike metal roofs, it will be less combustible than the conventional roofing materials like shingles or wood shakes.

Metal roofs are both non-combustible materials and an electrical conductor and hence the risks that are associated with its behavior and use during lightning events make it the most desirable construction in the market. These metals will not attract lightning because the lightning seeks to find a path to the ground and that is why structures like telephone poles, and trees tend to attract lightning more. Metal roofing is an isolated structural component that does not have a direct path to the ground. Therefore, there isn’t a scientific proof that lightning can easily strike metallic roofs more often than asphalt shingles.

Metal roofs last for more than 5o years and this tells you why they carry a longer warranty. Some of the roofs can take as long as 70 years before you notice any sign of depreciation. By this time, the property owner could have replaced the asphalt roofs between 3 to 5 times. Therefore, you may not find it necessary to replace or even repair your metal roof over your lifetime. However, there is a high possibility that you will replace an asphalt roofing 2 to 3 times during your life. Therefore, even though the installation cost of metal is high, you will save about 2 to 3 times in the long run when you compare with asphalt roofing.

One thing that makes metal roofs very popular is that they are typically fireproof. With a rise in the number of wildfires, metal roofing has become a popular option in Melbourne. Besides, insects like termites don’t eat metal roofs. These roofs are also resistant to mildew and rot. Metals conduct heat very fast from the sun and hence snow slides over them more quickly than the other roofing materials. It tells you why the demand for these roofs in the region has been in the rise.

The other benefit of metal roofs is that they work perfectly on roofs that have low slopes. There is a misconception that metal roofs are only ideal on roofs that have a steep slope. However, standing seam metal roofs work perfectly on roofs that have a gentle pitch. The roofing of these roofs come in large sheets that are raised and then sealed tightly together to help to resist water. Some sloping is crucial to ensure that the water runs off but virtually all homes will accept metal roofs. Therefore, you should not hesitate to install metal roofs because of the myths that surround the industry. It is good to understand that this is one of the most important roofing options in the market. You can be sure of getting the value for your money from this roofing system.
