Enter the roof, get the cut list and the quote, right on site.

Dachwerk works out the roof framing from a few measurements: every rafter with its length and cuts, the cut list for the saw and the quote for the customer. No internet, no account.

WHAT IT CALCULATES
• Common, hip, valley, jack and upper rafters
• Plumb cut, seat cut, cheek cut and birdsmouth depth
• Pitch, rise, run and roof area
• Lengths of eaves, verges, ridges, hips and valleys
• Gable, mono, hip, half-hip, hip-and-valley, gambrel and mansard roofs

CUT LIST AND TIMBER ORDER
Every jack rafter is listed at its own length, not as a range, with quantities and spacing. The timber order packs the pieces onto the stock lengths a merchant sells, counts the saw kerf and shows how much offcut to expect. At the saw, tick off the cutting plan one piece at a time.

QUOTE AND INVOICE
Timber, waste, labour and VAT on your own letterhead with your logo, straight from the roof you just worked out. Add your own items from your price book. The invoice takes the customer and items over from the quote. Send either as a PDF by email or messenger, or print it.

BUILT FOR THE JOB
• Works with no signal.
• Every job is its own project, showing where it stands.
• Metric or imperial. Pitch in degrees, percent or rise-in-run.
• Tap a measurement on the drawing to jump to the field that sets it.
• The screen stays on while you measure.
• In 27 languages.

WHO IT IS FOR
• Carpenters and roofers measuring and setting out on site
• Timber framers checking a timber order before it goes in
• Builders pricing an extension, a dormer, a garage or a shed

MORE THAN A RAFTER TABLE
A rafter table gives you a length per metre of run and leaves the rest to you. Dachwerk gives you the common rafter, every jack rafter at its own length, the cut angles, the pitch, the roof area and the timber order, and works it all out again the moment a measurement changes.

YOUR DATA STAYS YOURS
No account, no ads, no tracking. Your projects and business details live on your phone and nowhere else.

PLEASE NOTE
Dachwerk does geometry and planning. It is not structural engineering. Check the results against local building codes, structural requirements and manufacturer specifications.

FREE, WITH PRO AS ONE PURCHASE
The calculator, the drawings, the cut list and your letterhead are free, with no limit. On your first three roofs, quotes also go out the way Pro sends them: with no Dachwerk line and with a drawing of your roof. From the fourth roof on, quotes and invoices carry a short "Created with Dachwerk" line at the foot until you unlock Pro.
