Most Common Flat Roofing Problems

 

Introduction

Flat roofs have numerous advantages, including cost-effectiveness, accessibility, easy installation, and potential energy efficiency. They also offer practical space for various building components. However, proper maintenance is crucial, as the same characteristics that make flat roofs effective can become vulnerabilities over time. 

Whether you're a commercial building owner or a homeowner in Nashville, your roof will come with unique challenges that often demand more attention than standard pitched roofs. 

This makes us wonder what are the problems with flat roofs ?

Common Challenges with Flat Roofs

Ponding water

Flat roofs often lack the natural slope needed for proper drainage, making them susceptible to a common problemeknown as ponding water. When precipitation accumulates on the roof without draining adequately, standing water forms

in low-lying areas. This can lead to numerous issues, including roof sagging and potential leaks.

Over time, the standing water deteriorates roofing materials like asphalt or single-ply membranes, causing structural damage and leaks. Regular inspections are vital for identifying areas with poor drainage.

To combat this problem, professional roofing contractors install tapered insulation or create a gentle slope towards roof drains or scuppers for facilitating efficient water runoff. Additionally, keeping the roof clean from debris helps prevent ponding water and preserves the roof's integrity.

Cracking And Blistering

This is one of the most faced flat roof house problems.Temperature fluctuations, UV exposure, and the natural ageing of roofing materials can lead to the development of cracks and blisters on flat roofs over time. These issues create vulnerabilities for water infiltration, potentially leading to leaks and further damage.

Blisters, also known as alligatoring , are raised areas on the roof surface caused by the separation of layers within the roofing material. The presence of alligatoring, characterised by cracks and bubbles resembling an alligator's skin, is a clear indication that your flat roof has aged and deteriorated significantly. To mitigate these problems, it is essential to choose high-quality roofing materials.

Additionally, applying roof coatings specially formulated to protect against UV radiation and create a seamless barrier can provide an added layer of protection, avoiding flat roof damage. 

Roof Leaks

Leaks and lingering moisture are common issues with flat roofs, but being proactive can help avoid a total roof

replacement. Unlike sloped roofs, water doesn't have anywhere to go on flat roofs, leading to moisture seepage and

potential mould and mildew problems. 

Due to the absence of natural water runoff, flat roofs are more susceptible to leaks caused by weathering and material degradation. Thoroughly examining roof seams and flashing and applying a high-quality waterproof coating can enhance the roof's longevity and resistance to leaks.

Understanding Buckling

Asphalt flat roofs share a construction method similar to shingled roofs, using a membrane soaked in asphalt to cover

the entire roof in one continuous piece. 

However, unlike shingled roofs, the seamless nature of flat roof membranes can lead to challenges over time. As buildings shift and settle, the roof also experiences movement, potentially causing buckles to form in the asphalt membrane. 

Buckling indicates the flat roof's vulnerability and can lead to safety issues and further problems if left unattended. When noticing any signs of buckling, immediate action through roof repair by a professional Nashville roofer is crucial to prevent escalating damage and ensure the flat roof's long-term durability.

Punctures and Tears

Flat roofs often serve as functional spaces for installing equipment and performing maintenance. However, constant foot

traffic and activities can cause punctures and tears in the roofing membrane, leading to potential leaks and damage.

Controlling access to the roof and limiting foot traffic can help minimise this problem. 

Additionally, installing protective pads or walkways made from durable materials can prevent direct contact between the roofing membrane and equipment or people, preserving the roof's integrity and extending its lifespan.

Exposure

Exposure is at the core of all common roofing problems. Regardless of the roofing material's durability, the constant impact of the sun and other elements leads to unavoidable flat roof damage. Issues include sun exposure, lightning strikes, freezing, hail, wind damage, and wind-driven debris makes your roof weak .

In addition, less frequent problems may arise, such as oil damage in restaurants or exposure to pollutants and chemicals from the outside. It's vital to be vigilant about separated or exposed layers in the roof membrane.

Early detection of these issues through regular roof maintenance check-ups by professional Nashville roofing companies can prevent potential problems from escalating into more significant challenges.

Structural Movement

Structural movement, also referred to as thermal movement, is an inherent phenomenon wherein a building's envelope

undergoes expansion and contraction due to variations in temperature. This natural process exerts an impact not only

on the roofing assembly but also on the overall structural integrity of the edifice.

Commercial buildings, especially those in regions like Nashville, are particularly prone to experiencing substantial thermal movement. This is especially noticeable when the internal cooling systems establish a notable temperature differential in comparison to the external environment. 

Consequently, flat roof membranes can develop vulnerabilities such as cracks and splits, particularly around penetrations, seams, and flashing components. Properly addressing these challenges becomes crucial in ensuring the longevity and functionality of commercial roofing in Nashville or any other location.

Reduced Lifespan 

Flat roofs typically last 15-30 years despite professional installation. If your home has a flat roof, prepare for a replacement in the foreseeable future.

Debris Accumulation 

Unlike sloped residential roofs, flat roofs are prone to catching debris easily. The absence of a slope allows leaves,

branches, and other debris to accumulate on the flat roof, potentially obstructing drainage. If not promptly removed,

large piles of leaves can trap moisture, leading to flat roof issues over time.
