I'm working on a reroofing project. The roof has a parapet wall around the perimeter with a clay tile cap.
The roofing consultant wants to remove the tile cap and replace it with a standard metal cap so we can run the new TPO roofing under the cap flashing.
The owner wants to install a new tile cap or metal look alike cap.
Is there a metal cap that looks like the terra cotta clay caps? |

Neither the original clay tile parapet, or most shop-fabricated coping caps, meet the requirements of IBC (ANSI/SPRI /FM 4435 ES-1)
Some pre-manufactured coping manufactures may have a sheet metal design that meets the IBC requirements and look like clay tile. Many of these same manufacturers will provide custom profiles. |

Standard SMACNA coping assemblies meet building code requirements:

it is not necessary to have a proprietary, factory-fabricated assembly to meet code. |

Agree with Anon, I usually havnt had an issue getting a shop fabricated ES-1 compliant coping.
Metal-Era has a designer series profile that may simulate what you are looking for and meet ES-1.
One example:

I have requested information from the major manufacturers of MCM panels about whether their suggested coping designs have been tested as required by IBC 1504.5, but without response. After many exchanges of e-mails, one fabricator finally admitted that they do not have a tested design for ACM or other MCM copings. Does anyone have experience with building officials about using MCM copings? I suppose a work-around would be to separate the edge securement function for the roofing membrane from the MCM coping. Thoughts? |

Louis, keep us updated. I have to admit that I never have mentally combined my ES-1 and MCM requirements despite having had the combo on multiple projects. I just always have shown a term bar and figured that was enough.
The work around is what I have been doing by default i guess. Trouble is...i doubt there is a ES-1 approved termination bar, unless someone had extra money around and decided to take one for the industry. maybe...? |

Any more suggestions for a faux tile parapet cap? |

Brian,
Dave Stutzman and I are going to discuss specifying MCM cladding in the Specifying Practice Group web session on 13 July. The announcement hasn't been sent out yet, but mark your calendar to register for the discussion.
You see ACM copings all the time, but perhaps that's another thing building officials don't commonly enforce. |
