Frequent Disadvantages Of a Flat Roof & How To Prevent Them

Arizona Roofing Contractors Explain The Most Common Flat Roof Problems

Whether you own a commercial building that has a flat roof or just happen to have a uniquely built home, you probably know that a flat roof requires more maintenance than standard sloped roofs do. A flat roof is usually simpler to build but will require frequent maintenance and inspections to make sure it is continuing to function as it was designed. One of the most challenging elements of owning a home or building with a flat roof is knowing whether it needs replacement or just some minor repairs.

Here are some tips from a Glendale roofing contractor to help you understand some of the most common problems that occur with flat roofs, how to prevent them, and how to deal with them.

Alligatoring: Deteriorated Roof Asphalt

This strangely named condition is one of the surest signs that your flat roof needs replacement. Alligatoring happens when the asphalt used to build your building’s flat roof begins to age and lose its elasticity. It will start to crack or bubble and look similar to the skin of an alligator, hence its name. Unfortunately, once this happens, it means that your roof’s asphalt has deteriorated significantly, and needs to be completely replaced.

Roof Leaks & Moisture

Well known as the most common problem that flat roofs encounter, leaks and moisture can be effectively managed if you can stay on top of the problem and address it right after even small amounts of rain. All roofs can develop leaks, including sloped roofs, but the problem with flat roofs is that the water doesn’t have anywhere to go except down into the home or office space. When moisture lingers or seeps into the attic space, it can cause mold and fungal growth, which are harmful to health and cause your business significant liability. Prevent this issue with regular inspections from a Queen Creek roofing company and immediate maintenance whenever there is a problem.

Membrane Buckling: The End Of Your Roof’s Lifespan

Despite the difference in shape and angle, most flat asphalt roofs are designed similarly to shingled roofs. The surface of the roof is made with a membrane that is soaked in asphalt and then laid across the top of the building. However, unlike a traditional sloped and shingled roof, the membrane on top of a flat roof is made of one complete piece. Over time, as your home or commercial building shifts and settles, your roof will adjust itself as well. Excessive movement from the construction of the building will cause buckling of the asphalt membrane, marking the end of the flat roof’s lifespan. It’s not safe to live or work under a roof that is buckling, because a buckling roof is vulnerable to more significant problems such as termite infestations, mold growth, leaking, and even collapse. Phoenix’s new roof installation needs to happen as soon as possible.

Allowing Pooling Water On Your Flat Roof Can Damage It

Unlike a sloped roof, there is nowhere for rain and precipitation to travel after it lands on a building with a flat roof. As previously mentioned, homes settle over time, which means that roofs settle slightly, too. In severe cases, this will cause membrane buckling, but it’s more likely to affect how level your roof is and result in divots or dips that cause puddling after rainfall. Most roofing materials are designed to hold up to rainwater, but may not do as well with lingering puddles of water. Homeowners and building managers need to drain these pools immediately after a storm and verify that the water hasn’t traveled into the lower layers of the roof. Allowing water to puddle on the roof for extended periods will damage and reduce the lifespan of your flat roof.

The Danger Of Roof Cracks

Because of their shape, flat roofs are prone to more pressure than a sloped roof will encounter. If this pressure is not relieved, its buildup over time can cause the roof to crack. This is why it’s crucial to frequently check the condition of your flat roof and remove any debris that may have accumulated. If you discover a crack in your flat roof, it’s imperative to call Mesa Roof Repair immediately. Not only is your home exposed to the risk of water damage or pest infestation, but a roof crack means that your roof’s structure is compromised and needs urgent attention.

Flashing Damage Can Leave a Flat Roof Vulnerable To Moisture & Pests

Like other building materials, flat asphalt roofs will expand and contract slightly as the weather and temperatures change throughout the year. Eventually, this slight movement can loosen the flashing that was installed around the corners and edges of your roof, leaving it vulnerable to moisture or pests. Prevent this significant and unsightly problem by regularly inspecting your flat roof and repairing any damage right away. If the flashing deterioration becomes significant, your home or roof may end up needing serious repair.
