Flat roofs might seem unusual; however, they're a common sight on houses in the Southwest of the United States or any region that's dry. The dry climate of these areas means that architects aren't worried much about stagnant water and creating damage to roofs. But flat roofs tend to leak more frequently due to the fact that water doesn't drain away as it would on pitched roofing; rather, it collects and then disappears. If this happens, it allows the water to detect cracks in the roofing's structure. If you've never experienced an unsound roof, here are some obvious indications that you've got an issue with your roof:

• Stains and water damage on your walls and ceiling
• Bubbling paint
• The water is drippy, and it's not from the sink
• Mildew on ceilings or the exterior walls

If you own an older house or if you see indicators of an issue with your roof, it could be time to consider an overhaul of your roof. Here are the options available and how much they'll cost.

Metal Flat Roofing

Metal is among the most sought-after materials to replace flat roofs. Aluminum, particularly, is renowned for its strength and durability. Metal roofs that are flat can last for more than 35 years under ideal conditions. Additionally, it comes with the additional benefit of reflecting the sun's heat and keeping the cost of energy low. Metal roofing is typically available in large sheets. However, it is possible to order smaller sheets to be able to use them around special features or odd extensions of your roof. For instance, smaller terraces or covered stairs.

As with all items, there are negatives with metal roofs. When it is an opportunity to change a roof, they usually have to be removed completely. Roofers aren't capable of installing an entirely new roof over an existing roof made of metal. Metal roofs are also susceptible to corrosion. If this occurs, your roof will require replacement.

Replacing Your Flat Roof With EPDM

EPDM (Ethylene Propylene Diene Monome) is a kind of synthetic rubber that is made from recycled materials. EPDM roofing materials are strong and affordable. Don't be shocked if you see roofing contractors talking about TPO (thermoplastic polyolefin) often in conversation initially. EPDM is a well-liked option due to its strength and durability; simple to install and also has more longevity over metal roofs.

EPDM installation requires seaming; this means there is more chance that water will seep through the seams, which pull away from the roof and cause damage to your home. But when EPDM roofs are applied with spray, there is a lower chance of seams falling apart from your roof has been greatly decreased.

Built-Up Flat Roof Replacement

A flat roof that is built up is composed of gravel and tar. Many people think of built-up roofing as what they first think of in their mind when they imagine flat roofs. Roofs with built-ups were in fashion for quite a while because they're not just stylish, they are also effective in insulating.

Flat roofs that are built up are extremely durable because they're made up of many layers. But, the layers make the roof extremely heavy. If your house already has a built-in roof, then replacing it with a built-up roof is a smart option. If, however, you have a different flat roof, you need to talk to an approved roofer because it may be necessary to install additional roof support. Another issue is that your home has to be empty prior to when the roof is being installed due to the risks involved in the process of installation. If you have a timeline to follow, this can be a significant obstacle.
