Sheet metal scupper boxes suffer an extraordinarily high failure rate. Protect your home with custom, monolithic drain replacements and true building science.
TALK TO US CRITICAL WATER WARNINGSheet metal scupper boxes are notorious for being the bane of existence for average roofers throughout the city of Philadelphia. Designed to collect and discharge thousands of gallons of rainwater off flat roofs and fiberglass decks, standard metal scupper boxes experience extreme thermal movement that splits soldered joints and tears caulked perimeter seams wide open.
Furthermore, scupper boxes frequently appear to be leaking when the actual water intrusion is originating far upstream. Rainwater entering behind compromised parapet caps or unsealed masonry pointing travels silently along floor joists before exiting around the scupper box sleeve, leading amateur roofers to misdiagnose the scupper as the primary breach.
Attempting a static water "flood test" on any pitched roof or fiberglass-cladded deck is reckless. Forcing standing water under wall flashings and scupper sleeves creates massive, secondary structural damage inside living spaces below.
Metal scupper boxes expand and contract at vastly different rates than roofing membranes and fiberglass decks. This continuous thermal movement rips soldered joints and caulked seams apart, creating direct leak paths.
Water entering through masonry pointing or parapet caps routinely travels along interior framing before emerging at the scupper, causing inexperienced contractors to replace scuppers that were never leaking.
Commercial flood testing is completely dangerous for residential pitched roofs or fiberglass decks. Damming up drains forces standing water under flashing seams, destroying interior drywall.
Blasting high-pressure garden hoses directly into scupper boxes and sidewall sleeves forces water past drainage planes into dry structural framing, causing artificial breaches and rot.
Permanent scupper resolution requires ripping out failed metal boxes and installing custom-engineered, monolithic drains seamlessly integrated with the roof deck membrane to withstand thermal expansion.
An expert in roof drains evaluates parapet caps, deck pitches, and upstream masonry transitions simultaneously.
Consult our specialized Philadelphia leak detection team at FSI Restorations to locate drainage breaches without destructive testing.
Attempting static water flood tests or blasting high-pressure hoses around scupper sleeves forces water into unexposed structural wall cavities that were previously dry.
Artificial hose testing invalidates roof warranties, saturates interior framing lumber, and creates massive mold hazards behind ceiling drywall.
Never sign a liability waiver allowing anyone to flood your roof deck or blast high-pressure water into your drainage assemblies!
