Tpo roofing vs epdm epdm roofing is made from ethylene propylene diene monomer or a kind of rubber its primary advantage over tpo roofing is simply that it s cheaper.
Tpo roofing vs epdm tripolymer.
Tpo and epdm might look the same when they are installed but they are vastly different in terms of construction and features.
To restore a ballasted epdm roof there are two options.
When it comes to epdm vs tpo the most important thing to consider is the need of curb appeal durability and longevity for your roof.
Tpo is thermoplastic so you can heat weld seams and it s ideal for repairs.
Regardless of which membrane you choose it is better to spend more money and invest into a thicker membrane.
Unlike tpo some epdm roofs are ballasted meaning there s loose gravel that s laid down over the epdm.
This allows for fewer seams than its tpo counterpart.
Epdm has less curb appeal but has almost the same durability and lifespan as tpo roofs.
Tpo can be slightly cheaper than epdm comparing standard tpo roofing vs.
Tpo roofing membranes are more expensive than epdm.
The first option is to mechanically fasten the epdm roof down.
Epdm has a dark surface which in summer conditions will absorb heat forcing cooling systems to work overtime whereas tpo roofing reflects sunlight allowing commercial air conditioners to work more efficiently.
However in some cases tpo can be slightly less expensive.
Epdm roofing the price is fairly comparable.
One advantage of an epdm roof is that the average sheet size can be quite large.
Otherwise epdm roofing has worse performance and weaker seam strength meaning there is a greater risk of water intrusion where the sections of roofing connect.
One advantage tpo roofing has over epdm roofing is enhanced durability.
Tpo is much lighter and easier to install but epdm is a whole lot cheaper and lasts longer.
Whereas the standard tpo system comes in rolls of 5 8 10 or 12 feet wide by 50 or 100 feet long an epdm sheet can easily be ordered in a 50 foot by 50 foot section.
Tpo also has a somewhat higher resistance to punctures than epdm.
Tpo is less susceptible to leaks since tpo roofs don t have big seams like epdm roofs this makes them less vulnerable to water leaks as they age.
Both epdm and tpo roofs perform better and last longer if they are thicker.
Manufacturers add fiberglass and talc to tpo roofing to improve their durability.
Epdm cannot be welded and cannot be re taped when the weather is too cold to use primer and adhesives requiring a temporary fix until the weather warms up.
Simply clean the membrane and heat weld directly to it.
On the other hand tpo has a wide range of colors guaranteeing better property insulation.
