Although most commonly used in commercial roofing and construction, membrane roofing is becoming necessary in residential application. Membrane roofing is used in flat or nearly flat roofs and is used to prevent leaks – essentially by moving water off the roof.

  • Synthetic Rubber (Thermoset) roof is made pieces of large, flat synthetic rubber (or similar material) welded together at the seams to form one, continuous membrane.
  • Thermoplastic Membrane is similar to the synthetic rubber or thermoset roof, except the pieces do not form one, continuous membrane and instead the seams “lap” and are bonded chemically or by heat.
  • Modified Bitumen is often described as the evolution of asphalt roofing. Made from asphalt, modifiers and solvents, there are many ways to connect pieces of this roofing material. In a heat application process, the seams are heated to melt the asphalt and create a seal. There are also various other ways of connecting the asphalt in both cold systems, self adhesive and chemical.

Prior to the above three applications, commercial roofing was solved by a common flat roofing method of asphalt and gravel, where it’s difficult to seal all seams and connection points, causing much more maintenance. In the newer applications, we now have seamless applications or have bonds as strong as the body itself. This creates less maintenance over the life of your roof. Previous asphalt roofs degraded faster due to expansion and contraction throughout the day due to heat and UV exposure. The previous asphalt and gravel roof method had leaks that were harder to detect and did not form strong bonds to the roof. Our new systems resist expansion and contraction, and reflect much of the sun’s UV rays – they’re also attracted to the building, forming a better seal.

Also known as Steel Shingle, last about 50 years and possibly longer depending on both the method of installation and the moisture barrier (also known as the underlayment) used and are between the cost of shingle roofs and slate roofs.

Liquid applied waterproofing is the most common type of waterproofing. In this process, the roofing contractor applies a specialist liquid roof coating. Fluid applied waterproofing works well in commercial roofing in Bronx, New York, because of its effectiveness on various types of roof type configurations, be it: flat, pitched or domed.


Finding an economical waterproofing company in Bronx New York is a necessity due to our warm summers and cold winters often filled with rain, ice and snow. Imperiex Construction is pleased to offer extensive waterproofing services for both commercial and residential applications in Bronx, New York and the surrounding metropolitan areas. With a roof that exceeds the highest standards for wind resistance and solar reflectivity, it will save you thousands of dollars in reduced maintenance expense and energy consumption.

We have a multitude of urethane waterproofing options to choose from, inclusive of non-skid surfacing.

Tilt-up sealant replacements using high grade urethane sealants. Metal panels and sealants are some of the most cost effective and common forms of joint sealants available.

Allow us to restore moving joints using high grade urethane sealants from our trusted suppliers. Control joints have been the accepted solution to foundation cracking for years. This is because, through proper alleviation of stress-producing forces on the concrete by pre-installed joints, your foundation can remain intact for much longer than a structure without this support.

Are you experiencing leaks in concrete? Concrete injections are used for leak control in all concrete types.

Having water intrusion problems that are below grade? At Imperiex Construction, we can waterproof via sub-grade excavation and control and stop your below grade water intrusion problems.

Control of wall water seepage and intrusions. Our wall coatings and repellents work with brick, stucco, concrete, wood, and metal surfaces.

When the positive side won’t work, we can control of water intrusion from the inside of the building or residence.

Exterior Restoration

Exterior restorations are common in the New York Metropolitan area due to the aging inventory, extensive use of brick and masonry, along with our temperate climate. Roofing restorations are our specialty, from commercial to residential, allow us to show you how cost effective a restoration versus a replacement may be. Siding restorations are also common due to moisture and humidity, but are most cost effective.
