EPDM roofs require marginal maintenance, making them attractive to property owners. Some roofs only necessitate an acrylic paint job every decade to retain their color intensity.

To ensure the longevity and performance of your EPDM roof, cleaning and inspecting it annually is recommended. By conducting regular inspections and addressing potential issues early on, you can extend the lifespan of your EPDM roof and avoid costly repairs.

EPDM Roofing Disadvantages, Problems, and Solutions

While EPDM roofing offers many benefits, it has a few disadvantages. In this section, we’ll discuss common challenges EPDM roofing systems face and potential solutions to address these issues, ensuring you get the most out of your EPDM roof.

EPDM Shrinkage and Leaks

an EPDM roof that has shrinkage and possible leaks

One common issue EPDM roofing systems face is shrinkage, which occurs when the roof material shrinks over time due to exposure to direct sunlight. Shrinkage can lead to flashings being detached from the sides of the building, resulting in cracks and splits on the material’s surface, which may cause water intrusion and internal leaks. A roof replacement might be necessary to address the problem if sufficiently damaged over a prolonged period.

To mitigate and pro-actovely address shrinkage-related potential damage, consider employing a thicker EPDM membrane, a reinforced EPDM membrane, or a pre-taped EPDM membrane.

EPDM Failing Seams

Like any roofing system, EPDM is not immune to potential issues, with membrane seam failures being a primary concern. These failures can arise from various factors, such as poor installation, improper seam preparation, inadequate adhesive application, or thermal expansion/contraction stresses. Challenges emerge when seams separate or lose integrity, leading to water leaks and compromised insulation.

To mitigate such risks, installation by trained professionals is crucial. Utilizing manufacturer-recommended adhesives and seam tapes, ensuring proper surface cleaning, and employing seam testing methods during and after installation can significantly reduce the likelihood of seam failures. Regular inspections, timely repairs, and addressing issues promptly are essential practices to maintain the integrity of EPDM roofing and extend its service life.

EPDM Membrane Punctures

Puncture resistance is another factor to consider when selecting an EPDM roofing material. Although EPDM is known for its excellent resistance to tearing, punctures can still occur, particularly during installation or when the roof is exposed to sharp objects. To improve puncture resistance, consider incorporating external fleece reinforcement, which can significantly enhance puncture resistance. This reinforcement can be applied to the underside of the membrane, providing an additional layer of protection for the membrane against punctures.

EPDM Liquid Incompatibility

With EPDM, you must be aware of its incompatibility with asphalt-based products. It is imperative to avoid using roof cement flashing and asphalt-based roof coatings, including aluminum roof coatings and oil or gas liquids. These substances can compromise the integrity of the EPDM rubber membrane by triggering chemical reactions that result in deterioration, causing the EPDM membrane to weaken and deteriorate.

To manage this challenge, opt for EPDM-compatible materials for repairs or maintenance. If unsure about compatibility, consult the roofing material manufacturer or seek guidance from roofing professionals with expertise in EPDM systems. This proactive approach ensures the longevity of the EPDM and minimizes the risk of costly repairs and a shortened lifespan.

EPDM Roof Summary

In conclusion, EPDM roofing is a versatile and cost-effective solution for flat and low-slope roofs. Its durability, energy efficiency, and marginal maintenance requirements make it an attractive choice for commercial and residential buildings. By understanding the different types of EPDM membranes, installation methods, and potential challenges, you can choose the best roofing material for your specific needs. With proper installation and maintenance, your EPDM roof can provide long-lasting protection and energy savings for years.

Frequently Asked Questions

What is the disadvantage of EPDM?

EPDM is incompatible with asphalt-based oil and gas liquids and is very inert, making it a disadvantage for some applications. Also, intense sunlight exposure can cause an EPDM membrane to shrink.

What is the difference between EPDM and TPO roofing?

TPO roofing is a white single-ply membrane commonly used in commercial and residential roofing, while EPDM is a black synthetic rubber membrane typically seen in commercial and medical facilities.

Standing Seam Metal Roof - Everything You Need to Know

standing seam metal roof system

Wondering if a standing seam metal roofing system is the best roofing system for your property? Knowing how a standing seam metal roof is built, its advantages, disadvantages, and how long it lasts will help you determine whether it's right or not for your project.

atlantacommercialroofingcontractors.com gathered essential information about what a standing seam metal roof is, how one is built, how it differs from a metal roof, and its long lifespan.

What Is a Standing Seam Metal Roof

A standing seam metal roof is a roofing system consisting of metal panels joined together with raised seams. The panels are typically made from steel, aluminum, or copper and come in various colors and finishes.

"Standing seam" refers to the raised seams that run vertically along the length of each metal panel. These seams are raised above the panel surface level and are typically joined together using an interlocking mechanism. When properly installed, this creates a watertight seal that prevents water from penetrating the roof.

Standing seam metal roofing systems are popular because they are extremely durable, long-lasting, and require minimal maintenance. These roofs are energy-efficient, reflecting the sun's rays and helping keep a building’s interior cool in the summer. Additionally, they are fire-resistant and can withstand sustained high winds and other extreme weather conditions.

Components of a Standing Seam Metal Roof

standing seam metal roofing

A typical standing seam metal roof consists of multiple components, including the following:

  • Metal Panels - These are a roof’s main structural element, typically made from steel, aluminum, or copper.
  • Roof Underlayment - This protective layer is installed beneath the metal panels providing additional weather protection and preventing moisture from entering the building.
  • Roof Deck - This is the roof’s foundation and is typically made from wood, metal, or concrete (depending on the structure’s construction).
  • Flashing - This is typically a thin metal strip installed at the edges, penetrations, and roof seams to prevent water from penetrating the roof and causing damage or decay.
  • Fasteners - These are the screws or clips used to attach the metal panels to the roof deck. They are designed to allow for the panel’s thermal movement (expansion and contraction) and prevent damage to the roof.
  • Ridge Caps - These metal pieces covering the roof’s ridge (the roof’s uppermost part) provide additional weather protection.
  • Snow Guards - These are devices installed on the roof to prevent snow and ice from sliding off and causing damage or injury.

Each component plays a crucial role in a standing seam metal roof’s performance and durability. Proper installation and regular maintenance of these components are essential to ensure the roofing system’s longevity and effectiveness.

Standing Seam or Metal Roof - What’s the Difference?

The terms "standing seam" and "metal roof" are frequently used interchangeably, but there is a distinct difference between them. Consider the following:

A metal roof is a roofing system made from metal materials like steel, aluminum, or copper. It can be constructed in various styles, including standing seam, corrugated, and shingle.

However, a standing seam roof is a specific metal roof type featuring raised seams that run vertically along the panels. The seams are raised above the panel surface and are typically joined using a locking mechanism, creating a watertight seal helping prevent water from penetrating the roof.

contractor connecting standing seam metal roof

While standing seam roofs are a type of metal roof, not all metal roofs are standing seam. Other metal roof types may have different profiles, textures, and colors than standing seam roofs.

The principal difference between a standing seam roof and a metal roof is that a “standing seam” roof is a specific metal roof type featuring raised seams, while a “metal roof” refers to any roofing system made from metal components.

Standing Seam Metal Roof Pros and Cons

Standing seam metal roofs offer several advantages and disadvantages compared to other roofing systems. Consider the following pros and cons of standing seam metal roofs:

Advantages:

  • Durability - Standing seam metal roofs are incredibly durable, potentially lasting 50 years or more with proper maintenance.
  • Weather-Resistant - Metal roofs resist weather like high winds, hail, and heavy rain.
  • Energy-Efficient - Standing seam metal roofs are reflective, helping to reduce cooling costs in warmer climates.
  • Low Maintenance - Metal roofing systems require minimal maintenance and are relatively easy to clean.
  • Aesthetically Pleasing - Standing seam metal roofs offer a sleek, modern look complementing various architectural styles (potentially increasing a property’s curb appeal).

Disadvantages:

  • Installation Cost - Standing seam metal roofs can be significantly more expensive than other roofing systems, like asphalt shingles.
  • Noise - Rain, hail, and other precipitation can be extremely noisy on metal roofs, which can be a significant concern and deciding factor for some property owners.
  • Installation - Standing seam metal roof professional installation requires specialized equipment and expertise, which may add to the roof’s installation cost.
  • Expansion & Contraction - Metal roofs expand and contract with temperature changes, which may cause fasteners to loosen or back out over time, potentially leading to leaks.
  • Potential for Dents - Metal roofs are prone to denting when hit by large hail or other projectiles.

Standing seam metal roofs offer multiple benefits and are a popular choice for homeowners and commercial property owners wanting a durable, energy-efficient, and low-maintenance roofing solution. However, they may not be the ideal option for every roofing situation, and it's essential to weigh the advantages and disadvantages carefully before making a decision.

What is a Parapet Wall – Definition and Purpose

Parapet walls are vertical treated or flashed extensions of a roofing system

Need help understanding why there is a wall around your structure’s roof? Knowing why parapet walls are necessary and what they do will help you better appreciate their cost and maintenance.

atlantacommercialroofingcontractors.com gathered essential information about what a parapet wall is, the types of parapet walls, why they are built around a roofing system, and how they drain water from a roof.

What is a Parapet Wall

Parapet walls are typically short and thin walls constructed at the edges of a building’s roof, preferably around its perimeter. A parapet wall can be constructed as a balustrade or other architectural shapes. Parapets can also be found in houses, bridges, walkways, balconies, and other elevated surfaces.

Parapet walls are principally found on flat roofs, extending the vertical wall at the side of a house or building past the roofline. They’re usually required when you want the roof to double as a terrace, balcony, facilities area, or walkway, helping to keep the area as safe and protected as possible.

Types of Parapet Walls

Parapet walls can be paneled sloped embattled plain or perforated

A parapet wall can be constructed using materials like reinforced cement concrete, brick, steel, aluminum, glass, etc. Consider the following:

Plain Parapet Walls – These are nothing more than a vertical extension of the wall at the edge of a roofing system. It is a general type of parapet wall specifically designed and constructed for safety concerns.

Perforated Parapet Walls – A perforated parapet wall is also an extension of the wall like a plain parapet, but the extended wall portion is perforated with different-sized and shaped openings complimenting the aesthetic appearance of the structure.

Embattled Parapet Walls – These parapets harken back to the olden days, especially used for castles, forts, etc. Alternative low and raised portions and strategic perforations are provided in the parapet. Archers typically used these perforations to shoot arrows through in a castle’s defense.

Note: Their beautiful appearance and uniqueness have them being constructed around modern structures to enhance their aesthetic appeal.

Paneled Parapet Walls – These parapet walls are similar to plain parapets but are ornamented with panel designs on the outside of the parapet wall.

Sloped Parapet Wall – Sloped parapet walls are used for sloped roof structures like industrial constructions, trussed structures, etc.

Stepped Parapet Wall – These parapet walls are also used for inclined roofing systems. The parapet wall is typically built in a staircase-type (step) design.

Flat Parapet Wall – Flat parapet walls are typically recommended for flat roofs.

Arched Parapet Wall – Curved or arched parapet walls are recommended for flat and inclined roofs.

Parapet walls have multiple significant purposes, including the following:

  • To prevent dust and debris from collecting on the rooftop or getting into the HVAC system.
  • To prevent any gathered debris on the rooftop from falling.
  • To avoid high wind loads from severely impacting or damaging the enclosed roofing system.
  • To provide an aesthetic look to a structure, typically increasing its curb appeal.
  • Sufficiently tall parapet walls provide permanent safety protection for people when on a rooftop (inspections, maintenance, and equipment servicing) and on bridges to keep vehicles from falling or driving off the bridge.
  • To hide and prevent any equipment or machinery from ruining the structure’s aesthetics or falling off the rooftop.
Parapet walls protect people from plummeting off a roof

Note: Parapet walls are typically part of a structure’s original design.

How Do Parapet Walls Drain?

Scuppers. Roof scuppers are rectangular outlets in a parapet wall at a roof’s edge that function as a drainage device. Scuppers allow water to freely drain through an opening in a roof’s edge and are one of the most common and effective ways flat roofs drain.

Note: Scuppers are typically used in conjunction with gutters and downspouts to divert water to a desired location.

Parapet Wall

In this article, you discovered what a parapet wall is, different types of parapet walls, and how they protect a roofing system and people.

Understanding why your roof requires a parapet wall will help you better appreciate the associated construction cost and maintenance.

Improperly installed and maintained parapet walls can create a severe hazard for anyone on your roof, permit extensive wind and storm damage, and prevent your roof from properly shedding water.

Slate Roofing Advantages and Disadvantages

Slate roofing system

Need help determining if a slate roofing system is a suitable choice for your structure? Understanding the advantages and disadvantages of installing a slate roof will help you select the right roof for your structure and circumstances.

atlantacommercialroofingcontractors.com gathered essential information about slate roofing systems, their advantages, and disadvantages and answered some frequently asked questions.

What is Slate Roofing?

A slate roof is a premium roofing system made from natural slate tiles and other slate roofing components (slate is a fine-grained, metamorphic rock derived from a shale-type of sedimentary rock composed of clay and volcanic ash). Slate is among the most beautiful and long-lasting roofing systems available on today’s market. Because of its aesthetics, shingle manufacturers make asphalt or composite shingles to mimic the appearance of a slate roof.

Slate Roof Advantages

There are many excellent reasons for selecting a slate roofing system for your structure. Consider the following advantages:

Fire Resistance – As a stone product, slate is entirely fire resistant, unlike asphalt or composite shingles and other roofing materials. A slate roof naturally resists intense heat and fire. Slate roofing systems are ideal if wildfires and bushfires are a significant concern near your structure.

Multiple Color Availability – Slate comes in a variety of colors. The more common are grey, black, various green shades, deep purple, brick red, and other shades. The presence of carbonaceous matter (decaying marine organisms on ancient sea floors produces black-colored slate). Iron compounds generate red, purple, and green hues.

Low Maintenance – Beyond inspecting for broken or loose tiles and cleaning valleys and gutters, a slate roof requires no other significant maintenance.

Long Lifespan – With proper installation, care, and maintenance, a slate roof can last over 100 years; some roofs can exceed 150 years. In contrast, asphalt shingle roofs must be replaced every 20 to 30 years, wood shingles may only last 15 to 25 years, and even most metal roofs will not last over 50 years.

Minimal Waste – When a slate roof must be replaced, the slates can often be re-used. Rather than discarding them, they may be recycled on another roofing project, used in flooring, building garden pathways or driveways.

Slate roofing system removal

Energy-Efficient – Slate is a naturally energy-efficient material. It is very dense and can keep your structure cooler in the summer (prevents hot air from invading the attic space. The heavy, dense slate material in winter prevents warm air from escaping. Slate helps you save on your heating and cooling bills throughout the year.

Note: According to energy.gov, light-colored polymer slate shingles are considered a “cool” roofing option. Slate (metamorphic rock) tiles are not typically considered cool.

Cost Effective – A slate roof installation or replacement is expensive. However, the material superiority and craftsmanship will provide years (potentially generations) of continued service. Over the long term, natural slate tends to be a significantly better investment because several roofing systems (using other materials) will have to be installed during the lifespan of a single natural slate roof.

Slate Roof Disadvantages

Damaged slate roofing system

While slate roofing systems are superior to other roofs in several ways, some drawbacks must be taken into account, including the following:

Roof Weight – Slate shingles weigh approximately 650 to 1,800 pounds per square (1 square equals 100 square feet). Lighter-weight asphalt shingles typically weigh only about 200 pounds per square. Slate’s increased weight means some structures may require significant reinforcement before a slate roofing system can be installed, which increases project costs.

Foot Traffic – While slate is exceptionally durable, it does not hold up well to foot traffic. This means someone hired to service your external A/C unit or clean out your gutters walking on your roof can cause extensive damage to tiles.

Note: Professional roofers use hook ladders, jacks, and planks on slate roofing, allowing them to walk on the roofing system without damaging it.

Installation Requires Specialized Roofers – Typically, the average roofing contractor is not qualified to install a slate roofing system. Slate roofs require specialized installation from master slaters. Hiring a specialized roofing contractor means you’ll pay significantly more for your roof.

High Cost – Slate is among the most expensive roof material. That doesn’t mean it’s not a good investment. While it’s significantly more costly than other roofing materials, slate will easily last 100 years or more, making it a more equitable investment over its lifespan.

Note: The elevated up-front cost of a slate roof may make it too costly for some property owners, particularly those who will occupy the structure for a brief period.

What is the biggest problem with slate roofs?

The biggest problem with slate roofing systems is their excessively heavy weight. Except for clay tiles, no other “conventional” roofing product is as heavy. Per roofing square (or 100 square feet), slate weighs from 650 to 1,800 pounds.

Do you need to vent a slate roof?

Providing adequate attic ventilation is fundamental for all roofing systems, even when using a breathable underlay.

Can You Walk on a Slate Roof

No. While slate is durable, it can crack under direct pressure. Professional roofing technicians use hook ladders, jacks, and planks for weight distribution on slate roofing. Even when properly installed, foot traffic, falling tree branches, or sudden impacts can cause slate roof tiles to crack. Damaged slate tiles can result in leaks and costly repairs.

Everything You Need to Know about Roof Ventilation

Roof or attic vents are essential to removing hot air from the roofing system

Need help figuring out if your roof or attic has anything to do with why your home overheats during sunny, hot days? Understanding why your roof’s ventilation is crucial to its lifespan and your home’s comfort will help ensure it is properly ventilated.

atlantacommercialroofingcontractors.com gathered essential information about roof ventilation, what it is, and why it is a necessary component of your roofing system.

What is Roofing Ventilation?

Roof ventilation is a combined system of intake and exhaust vents providing air circulation to keep the atmosphere inside a home comfortable. Without adequate in and out passages in roof ventilation, hot air gets trapped within your home, causing multiple problems for your property (especially its roofing system).

How to Ventilate a Roof

Roof vents are typically installed at a roof’s peak, where the internal air rises naturally. Adding roof vents to your attic ensures warm, moist air can escape, preventing heat buildup and condensation. Like other roof components, you should periodically check your roof vents to ensure they are debris free.

How Many Roof Vents Should a House Have?

Roof or attic vents are typically spaced to accomplish sufficient ventilation

As a general guideline, your roof needs one square foot of vent for every 300 square feet of ceiling space (if your roof has a vapor barrier). If not, your roof should have one square foot of vent for every 150 square feet of ceiling space.

What Happens When a Roof is Not Ventilated?

Poor or non-existent roof or attic ventilation can cause attic temperatures to reach or exceed 150 degrees in summer. These high temperatures can lead to damaged shingles and other roofing materials, a buildup of condensation, and mold or mildew development. Some signs that your roof is improperly ventilated include the following:

  • Excessive moisture in the attic
  • Excessive temperatures inside your home
  • Visible (often premature) roof damage from moisture
  • Ice dams form in the winter months
  • Visible damage from moisture inside the home
  • Dry rot of roofing components

A maintenance program, including periodic roof inspections, can help you detect these issues early or prevent them altogether.

Tip: Contract a professional roofer to ensure that your roof’s ventilation is installed properly and is functioning as it should.

Should I Cover Roof Vents in the Winter?

No. You should leave your roof vents open during the winter months. During the winter, roof ventilation works to keep temperatures even. Closing your roof’s vents makes the attic space too warm and dry – dangerous conditions favoring mold and pests.

Can Rain Come in Through Roof Vents?

Yes. Some roof vents sit flat to the roof, with a “mushroom” hood and unprotected sides. On occasion, hard driving rain with strong wind will cause roof vents to leak. If your roof vent leaks during severe rainy weather, the rain may be wind-driven under the hood and into the vent.

Are Powered Roof Vents Worth the Investment?

Yes and no. While powered attic ventilators can offer some relief in the summer, how they do it is often not ideal or cost-effective. They can steal air from the home’s conditioned space, forcing air conditioning units to work harder, use more energy, and significantly increase utility bills.

Roof Vent Types

Metal roof vents are essential to cooling a structures attic space

The best roof ventilation systems extend the life of your roof and help lower your home’s energy bills. Different roof vents are more effective than others, but each type of vent has the essential task of either removing air from your attic (exhaust) or bringing fresh air in (intake). Consider the following roof vent types:

  • Ridge vents (most common exhaust)
  • Soffit vents (most popular for intake)
  • Off ridge vents
  • Roof turbines (whirlybird ventilation)
  • Box vents (louver vents)
  • Gable vents
  • Hard-wired (powered vents)
  • Solar-powered vents
  • Cupola vents

Roof vents are typically classified as exhaust or intake vents. Consider the following:

Exhaust Vents – Because hot air rises, exhaust vents are typically placed towards the roof line’s top. The most common exhaust vents used for modern roofing systems are ridge vents.

Intake Vents – Cooler air comes into your attic through intake vents placed lower on the roof line than its exhaust vents. Because cooler air enters underneath hot air (and because hot air rises), intake ventilation helps push hot air out of the attic.

Soffit vents are used to allow cooler air to enter attic space

How Much Does Roof Vent Installation Cost?

Roof vent installation costs can range from $300 to $1,000 (labor and materials). Prices may vary depending on the type of vent and if it is installed during or post-roof installation.

Tip: As material pricing is subject to supply and demand, inflation, etc., consult your professional roofer for the most current material and labor pricing.

Roof Ventilation

In this article, you discovered essential information on roofing ventilation and why it is necessary for your roofing system’s longevity and ability to maintain cool temperatures in your home.

Knowing why roof ventilation is so crucial will help you ensure it is installed correctly, extending your roof’s lifespan and causing less demand on your air conditioning system.

Allowing your roof to go improperly ventilated will result in damaged roofing material, a buildup of condensation in your attic, and intolerable temperatures in your home.
