Flat roofs can appear untraditional but are prominent in houses in the southwest U.S. or any tropical area. The drier climate in these areas ensures that architects do not have to think about stagnant rain and roof damage. Even so, flat roofs are more prone to leaking because water does not roll as it is on steep or pitched roofs. Rather, water just pools until evaporation. It helps the rain to find flaws on the top of the roof longer.  

If you never have a leaking roof, some signs that indicate that your roof is leaking are water damage, ceiling and wall stains, dripping water, mildew, and bubbling paint. If you notice these signs, then you might need to get roof replacement soon. 

The Good Things About Metal Roofs 

Metal is among the most popular replacement materials for flat roofs. Metal is recognized because of its durability, especially aluminum. A flat metal roof may last for nearly 35 years with proper maintenance. It also has the additional advantage of projecting sun heat, which lowers energy costs. Metal roofing is usually available in big sheets, although smaller sizes can be ordered and customized to suit your unique needs and the features required by unconventional roof additions, like in the case of narrow courtyards and protected stairwells. 

Like most items, metal roofs have certain downsides. When it is time to replace metal roofs, they are usually completely torn out. Roof contractors cannot put in a new metal roof on an existing roof. Metal roofs are vulnerable to corrosion as well. If that occurs, you must repair or replace the damaged part. 

Flat Roof Replacement Options 

Ethylene Propylene Diene Monomer or EDM is a synthetic rubber that’s made of recycled material. EPDM roofing is long-lasting and cost-effective. Don’t be shocked if the roofing contractor speaks about EPDM and TPO or thermoplastic polyolefin interchangeably. EPDM is a rather popular choice because its installation is easy, and the material is durable. Its life span is longer than metal roofs.  

The installation of EPDM systems requires seaming, so water is more likely to pass through seams that pull off the roof and damage your home. Nevertheless, when EPDM roofs are treated, the risk is significantly reduced. 

What are Engineered Flat Roofs? 

An engineered flat roof consists of gravel and tar. For a lot of many, built-up roofs are what flat roofs are. A built-up roof is common because they are attractive and effective insulators. Engineered flat roofs are very durable as they contain so many sheets. But the roof can get very heavy with these layers. If your house has a built-in roof, it’s a smart idea to replace it with another built-up roof.  

But in case you’ve got some form of flat roof, consult to an expert in roofing Waltham MA as additional roof support may have to be installed. Another drawback is that when such a roof is to be installed, the house must be vacated due to the hazards involved in this installation. This may be a big disadvantage if you have a deadline to meet.
