Cool Roof Savings on Uptown Whittier Warehouse — Long-Term View
What to do about a TPO roof in Uptown in the first forty-eight hours, and what to leave until Monday.
After a storm the useful work happens in the first two days, and most of it is documentation rather than repair. This is what to do about a TPO roof in Uptown Whittier once the wind drops.
What actually matters
Punctures are the most common TPO failure by a wide margin, and most of them are made by people rather than weather. Rooftop trades drop tools, drag equipment and set ladders down on a membrane that is perfectly capable of resisting rain and not at all capable of resisting a dropped screwdriver.
What to do in the first forty-eight hours
Document before you touch anything: wide photographs to establish the property, then close photographs of each item of damage, all dated. Weld testing is the item to insist on. A probe run along every seam while the crew is still on site costs nothing and finds the cold welds that would otherwise be discovered by a tenant in December. A tarp fixed through sound covering creates damage that was not there before.
How Uptown Whittier changes the answer
Summer is the problem here. Uptown sits inland with no marine influence to speak of, so a roof surface that reads ninety degrees at the coast is well past a hundred and fifty on Greenleaf by mid-afternoon, and it holds that heat for weeks. Everything on the roof expands into it and contracts again overnight, and it is that daily movement, not the peak temperature, that opens laps and backs fasteners out. Much of Uptown went up between the 1920s and the 1940s, which means original board decking, ventilation that was never sized for this much heat, and often a layer somebody roofed straight over rather than tearing off.
What we look at on an inspection
- Seam integrity, probed along the full length rather than spot-checked
- Punctures and abrasion, especially on traffic routes to rooftop plant
- Membrane shrinkage and any resulting tension at the perimeter
- Flashing and termination bar at every wall, curb and upstand
- Drain sumps and clamping rings, checked and clear
- Fastener plates showing through the membrane surface
- Weathering and chalking of the surface, particularly on exposed elevations
Common questions
Should I get a tarp on it straight away?
Only once it is photographed, and only if it can be fixed without putting new holes through sound covering. A badly fixed tarp creates damage that was not there before.
How soon do I need to report it?
Check your policy, because most impose a reporting window. Reporting early costs nothing and protects the claim.
The honest summary
TPO is a good system installed properly and an expensive mistake installed quickly. Seams and punctures decide its life, so protect the surface and test the welds. In Uptown Whittier the thing to watch is attic temperature and intake ventilation, because an Uptown attic that cannot breathe cooks the underside of the roof as hard as the sun cooks the top.
