Measure Walls

Fastest method: tape measure or laser on-site. Google Earth helps for wall length from above (no height info). Measure each wall separately for accuracy.

1

Walk the perimeter

Measure each wall's length at the base.

2

Estimate wall height

Single-story: 9 ft. Two-story: 18-20 ft.

3

Subtract big openings

Garage = ~112 sf. Standard window = ~12 sf. Subtract for accuracy or leave for waste buffer.

4

Use Google Earth for length

Search address, ruler tool, measure walls from above. Height from Zillow listing.

→ earth.google.com
5

Add each wall in calculator

Front, back, left, right minimum. Add gable ends separately.

Gable end: base × peak height ÷ 2. A 30ft wide gable peaking 8ft up = 120 sf.

About BSR

Built by Will Brambila, owner of BSR Constructions LLC. A family-owned roofing and exteriors company in Seattle, WA. Founded with my brother Art, we serve Pacific Northwest homeowners and contractors with the same focus every day. Do the work right. Treat people fair. Build something that lasts.

Family-built. Community-driven. Quality roofing & exterior solutions.

Why this tool exists

Every day on jobsites, contractors waste time doing math on the back of an envelope. Estimates take hours that should take minutes. Numbers get fuzzy. Profit gets lost in guesswork.

I built this tool to fix that for my own crew. Then I figured I'd share it.

It's a calculator I actually use. On roofs. In driveways. In front of homeowners. I wanted something that gave me a real bid number in 60 seconds without pulling out a laptop or doing 12 steps of math on a calculator app.

Who it's for

If you're another small business owner, contractor, or estimator out there grinding it out, this is for you too. Free. No login. No email capture. Just open it and use it on the jobsite.
