If you have a flat roof, you want to know about the longevity of this style. These roofs are different from peaked roofs, and they have specific needs to help maintain them. For those homes with flat roofs, here are a few things that you need to know about the durability of your roof.
The Longevity of Your Roof
For the most part, your flat roof should last about a decade. However, that time frame will depend on how well you have maintained the roof. Even with the best maintenance, there will be a time when you need to replace your roof. Flat roofs that have an expired warranty are probably ready for a replacement. Those newer flat roofs might need to be replaced if there is damage to the structure.
A flat roof provides a level surface to your home. Many homeowners have concerns about the increased chance of standing water and damage. However, your flat roof will have a membrane at the top of your home or building. The membrane can consist of several types of waterproof materials. Most flat roofs will use roofing felt as a base to the structure. The membrane will be placed on a structural base, and it stays put between the deck and flat roof. This material is also used as a vapor barrier.
You will need the vapor barrier to prevent any moisture from developing between the layers of the flat roof. If you are worried about moisture, there are a few components that can seal the edges of your roof, such as metal flashing. With the flashing, the water is moved away from the roof and directed into the gutter. All the excess water proceeds off the roof as you stay protected in your house.
Several Types of Flat Roofs
There are several types of flat roofing options for your home. One of the most common is roll asphalt. This roof uses organic or fiberglass felt that is soaked with asphalt. This combination of materials can be applied over the base of the roof. The roofing company will use nails and asphalt cement to seal off the remaining portion of the roof. At the end of the process, the roof is topped with mineral granules.
Built-up membranes use several layers of structured or coated roof felt, and they are installed in combination with asphalt. The roof is topped off with a layer of roofing sheeting or granules to help protect it from weathering. In some cases, the built-up membrane can last for over 30 years.
Single-ply membranes are gaining in popularity. This type of roof utilizes a single layer of material to help waterproof the roof. Many roofing companies will use this element as an alternative to the heavy built-up membranes.
A flat-seam metal roof takes small pieces of sheet metal and solders them to form a flat surface. Lead-coated copper or galvanized metal are the most common materials used for this roof.
Signs That You Need a Flat Roof Repair
Flat roofs are known for their stability. However, any type of roof will need to be replaced after a few decades of work. If you have inspected your roof and saw some signs of damage, it may be time for a roof replacement.
Your home should never leak. If you have water entering your home, you need to call a professional team to inspect your roof. Leaks can develop in the roof and trickle down your ceiling. After a storm, you want to check out your roof. Branches and wind gusts can tear apart a roof panel. If any panels have been damaged, you will need to have these parts replaced.
The vapor barrier is another essential part of your roof. Any damage to it will need to be repaired. Once the vapor barrier is torn, it can lead to water damage throughout the rest of your structure.
Finally, your top coating plays a crucial role in the performance of your flat roof. If this coating has been damaged, the undercoat can be exposed. These damaged materials leave your inner layers vulnerable to decay. In most cases, severely damaged flat roofs must be replaced.
Care Tips for Your New Roof
If you have an older flat roof, it may be time for a replacement. You should start the search for a roofing company that specializes in flat roof installations. Once the roof is installed, you want to take a few steps to ensure the longevity of your new purchase. Many roofing companies recommend that you add a layer of protective coating, such as polyvinyl. This type of material protects your roof from heavy rains and other weather events.
For those who want to extend the life of their flat roofs, you need regular maintenance for your structure. With the right care, you can keep it in excellent shape throughout the years. Flat roofs are prone to standing water. If the water is not removed after three days, then you could have permanent damage to your roof. For those extra-large roofs, you might want to install a roof pump. These machines can help to automatically pump water off your roof.
Flat Roofs Have Their Advantages
A flat roof is a great alternative to those peaked roofs around your neighborhood. You want to take care of this unique type of roof. Not only will your roof continue to look great, but you can help it have better durability and a longer lifespan for years to come.
