Know the Different Types of Flat Roof Solutions

flat roof solutions

People who choose flat or low-sloped roofs for their houses do so because of functionality and aesthetics. A flat roof, like other roof types, has the main function of protecting the house against the elements. In addition, flat and other low-sloped roofs look great on a variety of architectural styles including modern buildings.

While old flat roofs do not last as long as their pitched counterparts, advances in technology over the past decades saw the development of new membranes that can compete with pitched roofs in terms of lifespan. For those interested in knowing the common membranes available in the different types of flat roof solutions, we listed them below.


Flexible Thermo Polyolefin (TPO) is designed to correct issues associated with other Thermoplastic membranes by possessing better seam, puncture and tear strength. Sales of TPO membrane roofing in the United States exceed all other types of flat roofs. TPO is considered a green product because it can be recycled 100% without chemical byproduct.


EPDM (ethylene propylene diene monomer) is a synthetic rubber and the most widely-used single-ply roof membranes. It is reasonably-priced and has a warranted lifespan of up to 30 to 50 years when properly applied.

Metal Flat Roof

Metal is ideal for both flat and pitched roofs. Different metals such as steel, zinc, aluminum and copper are used as covers. Although it costs more than other roofing materials, metal more than makes up for the upfront cost by its durability and low-maintenance.

Modified Bitumen

Modifiers such as APP (tactic polypropylene) and SBS (styrene-butadiene-styrene) are added to enhance the performance of traditional roofing asphalt. APP was added to asphalt bitumen to improve its ageing quality. SBS, on the other hand, improves substandard asphalt and make it flexible like rubber.


Asphalt built-up roof (BUR) membrane uses multiple plies of asphalt-impregnated felt embedded in bitumen. The asphalt is applied on the bitumen while still hot to merge and form a single-piece material. The membrane is laminated several layers (up to four plies) to form a thick material. It is protected from wear and tear and sunlight by embedding crushed stone and other granules on the surface. Unlike other roofing systems, asphalt roof installation is energy-intensive and adds to air pollution.

Turbo Seals

A gel-life membrane composed of 45% recycled tire rubber. It is placed on top of existing asphalt roofs and covered by a sheet membrane.

PVC Roofing

Polyvinyl Chloride (PVC) membrane roofing is also known as vinyl roofing. Because of its light color that reflects sunlight, PVC roofs are energy efficient. They are also used to waterproof green roofs.

What is an EPDM Gasket?


Gaskets play an important role in a mechanical assembly. They act primarily as the seal between two attached parts so that no leak occurs between them. To function as they are designed to, gaskets must produce an initial seal and maintain this seal over a period of time. Once the time comes, they must also be easily removed and replaced.

Gasket Materials

Gaskets are usually made from flexible and soft materials such as rubber and often utilized as seals to prevent leaks in pipes. They have other purposes, however, such as dampening vibrations and as mounting.

Rubber gaskets are preferred because they are soft and have inherent properties based on the kind of materials used. One of the most popular types of rubber gasket is EPDM gasket because of its desirable qualities.

EPDM Gasket

EPDM (Ethylene Propylene Diene Monomer) is a synthetic elastomer rubber with a wide range of industrial and commercial uses. This substance is used for seals (in those times when silicon is unwanted), electrical insulation, solar panels, belts, tubing, radiators, garden hose, washers and electrical insulation.

Qualities of EPDM Gasket

Its main properties include its exceptional resistance to heat, ozone and weather. The product is also well-known for its electrical insulating properties and resistance to ordinary diluted acids, alkaline and ketones.

EPDM gasket is, in fact, one of the most widely-used sealants for its superior performance even in extreme weather conditions. It maintains stability at temperatures range of -50°C to 150°C.

The product does not leave stains on PVC window frames.

It is compatible with hot and cold water and fireproof hydraulic fluids.

Compared to gaskets manufactured from different materials, EPDM gasket is resistant to extreme weather, ageing, wear, oxygen, ozone and UV light. That is why it is ideal for exposed applications.

Common Uses and Application

EPDM gasket’s most common use is in the automotive industry where they are widely applied in automobiles as window seals, trunk seals, door seals and hood seals.

It is also a popular choice among contractors and roofers as roofing membrane. A desirable quality of the product is that it does not contaminate rainwater, an ideal situation for rainwater harvesting.

EPDM granules are combined with polyurethane binders and sprayed on asphalt, concrete, wood, bricks to produce soft and non-slip safety surface for wet areas such as pool decks.

Another useful application of the product is its use as safety surface for playground equipment to lessen injuries from falls.
