Its much easier to spend a little more time to do a good weld, than TO take off the whole deck just to find one leak.Ħ. When overlapping seams, we recommend using double welding on all seams to prevent and eliminate all possible roof leaks due to seam failure. This is important because railings and walls are a common source of leaks on roof decks.ĥ.

Install all railing posts outside the roof perimeter, to prevent unnecessary penetrations and possible leaks. However, we’ve installed roof decks, where membrane and insulation was mechanically attached.Ĥ. It is best to fully adhere BOTH the insulation and the TPO membrane. It is important to use ONLY high density insulation or DensDeck under the membrane. You should ONLY use an 80 mil membrane, because thinner membranes have a high risk of tearing.Ģ. To ensure that your roof deck is completely watertight and will last a long time, we recommend the following TPO membrane installation guidelines:ġ. This presents a major deterrent to homeowners with tight budget. High Price: TPO costs almost 30% more than EPDM or built-up roofing.

Membrane can be installed over plywood or a concrete surface.ġ. Resistant to Damage: in case the deck will need to be removed in order to make some repairs/changes to the roofing membrane, TPO will not be damaged in this process.ĥ. Durability and Longevity: TPO will not fail and start to leak after 6-8 years, which is the expected service life of EPDM and built-up materials waterproofing materials for decks.Ĥ. Also makes any repairs very fast and easy.ģ. Hot-welded seam technology makes the membrane impervious to leaks (when done properly). When estimating your total budget, you should also factor in the cost of PROs and CONs of using a TPO membrane to Waterproof a Roof DeckĪs with any material, a TPO membrane has a distinct set of pros & cons, that may not make it the right choice for every home.ġ. The cost will vary depending on the thickness of the membrane you select (we recommend using an 80 mil membrane, which will cost more), your location and the contractor you hire. On roof decks you will spend about $9-11/sq. How Much Does A TPO Roofing Membrane Cost?īeing a highly durable and long lasting material, TPO comes with a higher price tag than EPDM rubber or built-up roofing.Įxpect to spend about $6.50-8.00/sq.ft installed, on a normal roof.
