Maximum Slope For Epdm Roofing

Normally 1 80 0 72 is the recommended minimum angle for a slope and this is universal across the vast majority of flat roofing systems regardless of the materials that they incorporate.

Maximum slope for epdm roofing.

In order to achieve this drop a slightly steeper angle of 1 40 1 44 should be the aim when installing a flat roof as this accounts for surface deviations and material deflection among other things. Adhered systems using fire retarded sheets can meet code at virtually any slope to vertical. Rubbergard max epdm reinforced membrane available in 45 60 and 75 mil rubbergard max reinforced epdm is an internally reinforced cured single ply roofing membrane that is designed to combat roof tears and punctures and provides superior resistance to wind forces. Epdm is fine if there is enough slope to drain any water off the roof within 24 hours of the last percipitation event.

With the rubbergard r m a. As early as 1980 epdm had captured 40 to 45 percent of the single ply market. Some tpo membrane assemblies also have relatively low maximum roof slope limitations.

The epdm ethylene propylene diene terpolymer single ply rubber roofing membrane has been an appealing choice of the low slope commercial roofing industry for over 40 years. If you are looking for added strength to what is already the longest. System that uses large epdm panels. For example some epdm membrane assemblies have maximum roof slope limitations as low as 1 2 12.

The following table provides the minimum required allowable roof slope for each type of roofing material mentioned in the code. 1 8 slope per foot is more than adequate. The minimum roof slope allowed by code for any type of roof is in 12 applicable only to coal tar pitch roof systems. Pvc membrane assemblies generally have higher maximum roof slope limitations.

The main component of the roofing system is the firestone rubbergard membrane a tough flexible epdm ethylene propylene diene terpolymer based sheet which is fully vulcanized to provide excellent dimensional stability and weathering resistance. System product slope barrel arch etc. The rubbergard max epdm membrane is an internally reinforced cured single ply roofing membrane that is designed to combat roof tears and punctures and provides superior resistance to wind forces.
