🏗️ This Week in Roofing History
📍 Philadelphia, Pennsylvania | 1910s
This handwritten invoice documents repair work performed by William Hone, whose scope included tin, slag, and cement roofing—along with related repair services.
This wasn’t new construction.
It was diagnosis and repair.
In this period:
• Roofing contractors handled ongoing maintenance and leak repair
• Slag and tin roofs required regular inspection and patching
• Repairs were carefully measured, described, and priced
• Labor and materials were itemized by task
• Payment followed completed, documented work
The handwritten notes tell the real story:
Areas inspected.
Sections repaired.
Flashing addressed.
Back buildings included.
Costs totaled line by line.
This is early service estimating, done without photos, moisture scans, or software—just experience, observation, and accountability.
The contractor who inspected the roof was the same one writing the scope and standing behind the repair.
That connection mattered then.
It still does now.
History reminder:
The tools change.
The responsibility doesn’t.

Operational Tuesdays – Estimating
Labor is the hardest part of estimating to control—and the easiest to underestimate.
Historical data matters more than optimism.
Optimistic labor assumptions usually show up later as blown budgets.

🏗️ This Week in Roofing History
📍 United States | 1930s
This piece comes from Mule-Hide, promoting roofing systems not just for protection—but for appearance.
“Your new roof in colors beautiful.”
That was a shift.
By the 1930s:
• Roofing manufacturers were marketing aesthetics, not just durability
• Color became a selling feature, not a byproduct
• Branding and slogans entered roofing vocabulary
• Performance was assumed—differentiation came next
The tagline says it all:
“Not a kick in a million feet.”
It’s confidence.
It’s branding.
And it’s early proof that roofing had moved beyond commodity thinking.
This era marked the beginning of roofing as a visible design choice, not just a functional necessity—especially for residential and light commercial buildings.
Today’s conversations about curb appeal, architectural compatibility, and color palettes trace directly back to moments like this, when manufacturers realized roofs weren’t just built to last—they were built to be seen.
History reminder:
The tools change.
The responsibility doesn’t.

Estimating isn’t only about numbers.
It’s about understanding risk and knowing which jobs make sense for the company.
Winning work is good—winning the right work is better.

🧱 Laps & Splices: Where Good Roofs Fail First ⚠️

Most modified bitumen leaks don’t start in the field—they start at the lap. Fishmouths and voids may look minor, but they’re the fastest path to water intrusion.

Here’s the correct field repair sequence:

• Cut the fishmouth or void cleanly with a hook blade so the membrane can lay flat
• Remove dirt and debris and inspect the area for water infiltration
• If moisture is present, open the membrane and replace any wet insulation or damaged deck
• Thoroughly clean and prep the repair area beyond the defect for proper tie-in
• Remove embedded aggregate and smooth the surface as needed
• Prime lightly—enough to support adhesion without saturating the membrane
• Cut a like-material patch at least 8" larger than the defect and round all corners
• Install using hot asphalt (SBS), cold adhesive, or heat welding per manufacturer requirements
• Apply firm, even pressure to fully bond the patch

If the lap isn’t sealed, the system isn’t sealed.

File this one away—small details prevent big leaks.

Operational Tuesdays – Crew Leadership
Crews perform best when expectations are set before the first tool comes out.
Morning planning matters more than end-of-day corrections.
Reactive leadership costs more time than it saves.
