<p>Created page with "Parameters for assessing cost and practicality: #Materials: EPDM, TPO or PVC #Installation method: fully adhered, mechanically fasteners + heat welded (seams only) or mechanic..."</p>
<p><b>New page</b></p><div>Parameters for assessing cost and practicality:<br />
#Materials: EPDM, TPO or PVC<br />
#Installation method: fully adhered, mechanically fasteners + heat welded (seams only) or mechanically fastened + glued (seams only)<br />
#Form factor: all of these materials come in a variety of sizes - but none is a perfect fit for our roof size - so we need to pick the one that leads to the least waste (cut ends)<br />
<br />
Suppliers that sell directly to the public.<br />
<br />
Roofkit (EPDM only, I think):<br />
*Product line at menards: 45 mil EPDM, latex adhesive, primer, seam tape. This comes out to around $1.15/sq ft - but that doesn't include the cost of seams (which use primer and seam tape) nor waste due to form factor.<br />
*Installation manual<br />
*Website - with installation videos and FAQ<br />
<br />
WeatherBond (EPDM, TPO and PVC)<br />
*Comes in a variety of sizes (for example). Can also be acquired by the foot.<br />
*Fastener plates<br />
*Installation videos<br />
*Loads of technical and how-to details (if you can make sense of them):<br />

<br />
Installing mechanically fastened TPO seems relatively straightforward up to a point (you unroll the membrane, fasten the edges to the deck with screws and plates, overlap the next sheet and heat-weld the seam). But on the written instructions they keep talking about "perimeter sheets" - but I can't find out what perimeter sheets are, how many we need, how much they cost nor how to install them (are they glued?). It's like a ghost material :)<br />
<br />
They also make a weld-free TPO, but I can't find it for sale online (we may need to contact the manufacturer). '''Weld-free means Seam Tape'''.<br />
<br />

#https://www.weatherbondroofing.com/wp-content/uploads/WB-1042-Weld-Free-TPO-Installation-Guide_02-01-18.pdf<br />
<br />
One more thing: [[Elijah]] says he doesn't know whether TPO can still be heat-welded after prolonged exposure to UV. So this is a question for the manufacturer - as it would affect if and how we could reuse the membrane.<br />
