Modified Bitumen Roof | Buy at a Cheap Price

EPDM (Ethylene Propylene Diene Monomer) vs Mod-bit (Modified Bitumen) are only two of the several types of flat roofing systems currently available.

Despite the fact that each has its own advantages and disadvantages, these are two of the most prevalent systems used in residential and commercial roof applications today.

Until the early 2000s, bitumen felt had been the industry standard for flat roofing for well over half a century.

A large number of homes with garages, bay windows with extended sills, and porches were constructed using this material.

Despite this, it was not long before homeowners began to grumble about the inefficiency of this roof covering.

In the decades that have gone since then, advances in felt roofing have lowered the risk of failure connected with it to some extent.

Even today, a substantial percentage of conventional roofers are so set in their ways that they will only install felt.

For the rest of us, it is a great boon that, over the past 15 years, contemporary advances in flat roof coverings have completely redefined the sector, resulting in a great deal of success for flat roofers.

On the other hand, EPDM (Ethylene Propylene Diene Monomers) was able to pass through.

Year after year, as a result of its popularity, Pennsylvania manufacturing facilities have shipped substantial quantities to areas throughout the globe.

What is bituminous felt and what are EPDM roofs: This synthetic, man-made rubber membrane is created by mixing a number of fundamental components, which are then extruded into strips through a pressing and rolling process.

Bituminous felt is alternative roofing material.

Following the installation of layers designed to divide the fabric, the rubber is heated in an oven with sulfur to increase its strength and flexibility.

This stage terminates the production procedure.

This is the last procedure that must be carried out before rubber may be installed on structures in different parts of the world.

Bitumen Modified Bitumen, commonly known as felt, consists of three layers: boards, tar, and mineral.

The bitumen-based tar is spread with a bare flame, and then a coating of crushed slate is applied on top (normally Westmorland slate, on older flat roofs).

Survival rate: In the vast majority of cases, the expertise of the roofing contractor selected to install the roof will be the single most critical element in determining the roof's expected lifespan.

EPDM has a lifespan of 50 years, which is far longer than the bitumen-felt materials with which it competes.

Typically, when a provider installs EPDM on a customer's residence, the company will provide a 20-year warranty.

Mineral felt has an average lifespan of five to ten years, but I cannot begin to count the number of times I've observed it fail to meet this expectation.

In contrast, this is often the result of incompetent installation rather than the product itself.

Five years is the typical length of time a company will stand behind its work when installing a felt roof.

I totally agree with the saying you get what you pay for regarding pricing.

EPDM is more than twice as expensive per square meter as felt, but it has a life expectancy that is more than three times as long.

If a client intends to make their existing residence their forever home, it should be evident that you should advise them to invest in an EPDM roof, which may never need to be replaced.

In the end, you receive what you pay for when you shop on the cheap.

During installation, the torch-on application method and the use of an open flame are two of the key causes of concern with felt roofing.

On the premises of the vast majority of commercial workplaces, the use of a gas torch is prohibited.

This is owing to the fact that it is responsible for the majority of catastrophic fires that occur each year, posing the biggest threat to employees.

The EPDM installation procedure does not include heat or flame, making it both easier and safer.

In the majority of instances, a water-based adhesive is recommended to achieve total component attachment.

You may get mineral felt in widths of one meter and lengths of up to ten meters.

This signifies that there would be a high demand for a significant number of seams and joints on broader projects.

Depending on the manufacturer, EPDM can be placed in a manner that is specially adapted to your attic's measurements.

There are certain manufacturers whose products can be up to 20 meters wide and 20 meters long.

This eliminates the need for joints, seams, and nails on bigger roofs, which is significant because virtually all issues with flat roofs begin at the joints.

EPDM is frequently regarded as one of the easiest and safest systems to install.

There is no comparison between bituminous felt and EPDM systems in terms of their ability to tolerate the amount of wear and tear over time.

Only the fact that they are both present due to their waterproofing properties is their only shared characteristic.

Rubber is particularly resistant to all sorts of deterioration caused by contact with the weather, which is why its use is growing in locations with a variety of climatic conditions.

Moreover, rubber is impervious to ultraviolet radiation and does not degrade when exposed to it.

It is extremely flexible and may expand to a size that is 200% greater than its initial size.

Even if you attempt to cause severe damage to the rubber with a chainsaw, the membrane will not be penetrated, torn, or split!

Classic Bonds now offers a rubber membrane with a fleece back, which provides an additional layer of durability and strength.

EPDM is unaffected by foot movement and requires minimal to no maintenance, making it a perfect material for heavily traveled locations.

When treated to specific conditions, felt will progressively lose its quality over time and require constant maintenance.

In roof areas that are frequently traveled by foot, the protective coating of crushed minerals will degrade with time.

It is likely that the bitumen base underneath will crack and break if exposed to the sun's ultraviolet rays.

Due to its rigidity, felt is easily ripped when penetrated by sharp objects.

The installation technique is lengthier and error-prone due to human interaction.

When felt is subjected to extremely low or high temperatures, it deteriorates more rapidly.

In terms of aesthetics, felt roofing is frequently grey in color. It can be installed in a variety of colors, but its overall appearance is dull and slightly dated.

It can also be installed.

EPDM rubber has an undeniably more modern appearance than bituminous felt when the two are compared.

Properly installed, it is considerably easier to smooth down and make flush, and it lacks the unsightly seams and connections of a felt roof.

Powder-coated aluminum drips and edges can be used to generate a fascia-like look.

Rubber is a dark matt black color.

If aesthetics prove to be the deciding factor, then EPDM will emerge victorious.

Asphalt to which various modifiers have been added to produce a rubber-like quality is the major component of the conventional modified bitumen flat roofing system.

Each roll of mod bit membrane can cover an area of roughly 100 square feet and is available in widths ranging from 36 to 39 Mineral granules, copper, aluminum, and aggregate are all potential surface materials.

Typically, torch-applied mod bit systems have one, two, or three plies and are of the one-, two-, or three-ply varieties.

Installation costs are far less than those of the great majority of single-ply systems now on the market.

In contrast to EPDM, which is typically only available in black and white, mod bit is available in a variety of hues.

Because the vast majority of mod bit systems are applied with a torch, roofs may develop leaks if the proper moisture barrier is not installed behind the coping cap on the parapet walls.

Inadequate head laps and backwater laps, both of which permit moisture entry, are a common issue with this system.

Leaks and blisters are two outcomes of backwater laps, which could ultimately lead to the roof's collapse.

Even when employing a cold-applied mod bit system, there is still the possibility of moisture infiltration and insufficient adhesive application, both of which might result in poor lamination and roof leaks.

The ethylene propylene diene monomer (EPDM) roofing membrane is a single-ply, flexible rubber membrane that may be easily trimmed to fit any application.

This system may be fully cured prior to installation, or it may be allowed to cure through natural weathering after installation.

Both possibilities are available.

The three most common techniques of application are the fully-adhered approach, the mechanically-fastened method, and the loose-laid method.

The first method includes employing water-based adhesives to adhere the rubber to the substrate.

The second method is a substrate attachment that employs manufacturer-permitted mechanical techniques.

In the third method, membranes are simply secured around the perimeter and at any penetrations.

Typically, adhesive or splice tape is used in the EPDM roofing system sealing procedure.

EPDM may be installed in one piece, so there is no need to worry about roof leaks or separating joints.

In addition, it is resistant to cracking, peeling, and splitting, as well as air pollution.

Due to its extremely high elasticity, it can stretch to more than 300% in order to accommodate temperature and building movement changes.

EPDM roofing systems have a lifespan of around 20 years and require minimal to no maintenance during that time.

EPDM and modified bitumen could be advantageous to the industry of flat roofing.

EPDM is more eco-friendly, simpler to install, and tends to have a longer life cycle when installed properly.

On the other hand, mod bit is typically less expensive and offers more aesthetically pleasing options.
