Flat Roofing in Kirkland

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. However, many homeowners are still drawn to this type of roof because of their energy efficiency. Whether you are considering a flat roofing system or have one already, Pro Roofing NW can help with all your issues. Our over 12 years of experience installing and servicing flat roofs make us an expert when it comes to this type of roofing system. Using only the best materials like 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 Roofing Systems

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 Installation

At Pro Roofing NW, we firmly believe that our experienced Kirkland 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 roofers do, condensation will get trapped from inside the home and form leaks.

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

Our installation process is as follows:

• After tearing off your old roof, we remove the rotten wood and rebuild as necessary
• 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 venting

Pro Roofing NW usually installs 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.
