Flat Roof Installation

Benefits of Flat Roofs

For both residential and commercial buildings, there are significant benefits that make a flat roof well worth the choice. The main reason for many is cost savings: Installing a flat roof saves money on material and installation costs, and on heating bills every year after. As heat rises, it’s drawn to the heights of a traditional angled roof, requiring more energy to heat the inside of the building. A flat roof retains heat in the main part of the building, saving significantly on heating costs.

Another main benefit to installing a flat roof is the opportunities it presents: An apartment complex, office building, or other shared space with a flat roof may have a rooftop garden, lounge, or green roof to provide a gorgeous community space that raises the value of the properties within. A flat roof may also be essential to a business such as a hospital that requires helicopter accessibility, or a parking structure seeking to maximize available spots. While there are many benefits to installing a flat roof, there are also considerations to prevent costly problems in the future.

Solving Problems with Flat Roofs

Unlike asphalt shingles or tiled roofs that have overlapping pieces to easily shed water, flat roofs have extremely low slopes that tend to retain water. Whether you are considering a flat roofing system or have one already, our expert Western Washington roof installers can help with all your issues. Our over 12 years of experience installing and repairing flat roofs make us a valuable asset when it comes to installing and maintaining your flat roof. Using only the best materials including vinyl roof membranes, we make sure our flat roof installations are always done right, so customers like you can have the peace of mind you deserve.

Why We Choose Vinyl for Flat Roof Installation

There are two kinds of vinyl roof membranes: polyvinyl chloride or PVC and thermoplastic polyolefin or TPO. PVC and TPO sheets are made out of flexible plastic materials that are welded together to create a seamless sheet covering for your entire roof. Unlike other materials like wood, these plastic sheets can last 25 years or more with proper maintenance.

Here are some characteristics of heat-welded PVC and TPO sheet roofing:

• Flexible even in cold weather
• Class A fire resistant
• Puncture and tear resistant
• Holds up well to standing water
• Chemicals and grease resistant
• Available in many different colors

Providing Expert Flat Roof Installation

At Pro Roofing NW, we firmly believe that our experienced greater Seattle area roofing contractors are the best in the field. It’s not just the care we take, it’s the techniques we use. For example, one of the problems with PVC and TPO is they don’t breathe, so water vapor is unable to pass through. If the roof is simply covered with a sheet of PVC, as many other flat roof installers do, condensation will get trapped from inside the home and form leaks.

Fortunately, we are the experts when it comes to flat roof installation as well as repair. We follow strict quality and safety protocols to ensure a reliable and efficient flat roofing service.

Our installation process is as follows:

• After removing your old roof, we fully remove any rotten or worn foundation and install only with strong and carefully selected material such as vinyl roof membranes
• We then apply ice and water shield, which is a waterproof but breathable product, to the roof deck
• We apply a separator sheet designed to absorb small quantities of moisture
• We place the PVC or TPO sheeting
• We ensure proper roof ventilation in order to prevent and mitigate the need for costly flat roof repairs later on

Our Western Washington roofing experts install two kinds of vents on flat roofs. One vents the attic under the roof while the other vents the separator sheet, so any water or moisture can easily pass through.
