Material takeoffs and quote calculations for roofing contractors
Roofing contractors use an AI employee to calculate material quantities and put together quote documents. The AI works out the roof area, estimates how much sheet metal, underlayment, battens, and fixings are needed, and produces an itemized quote. The biggest time saving comes from not having to rebuild the same quote structure from scratch every time.
A roofing contractor's year: season and paperwork
The year for a roofing company is seasonal. Spring and summer are the busiest months: you should be up on roofs, but quote requests come in faster than you can calculate them.
A roofing quote needs site-specific information: roof area, pitch, existing material, eave details, penetrations. Working out material quantities isn't complicated, but it takes time. Especially when you're also supposed to be on site.
Housing cooperative boards make decisions slowly. A quote request comes in the spring, the board meets in the autumn, and the work might happen the following summer. The contractor needs to keep track of where each job stands.
Warranty work is another administrative burden. Roofing jobs carry a 10-year warranty. You need to keep records of warranty sites and carry out inspections on schedule. A notebook isn't the most reliable system for that.
What it actually does
Roof area and material quantity calculations
The AI employee calculates roof areas from floor plans or satellite images. It estimates quantities for sheet metal profiles, underlayment, battens, fixings, and eave trim. Penetrations, chimneys, and roof windows are included.
Material takeoffs take 1-3 hours less per job.
Public tender monitoring
The AI employee monitors the Hilma public procurement database and flags roofing tender notices. It filters by region and building type, and puts together a weekly summary of new requests.
You don't miss relevant public tenders.
Warranty site tracking
The AI employee keeps records of warranty sites: installation date, warranty period, next inspection due. It sends reminders and drafts the inspection report template.
Warranty obligations stay organized without separate software.
Targeted outreach to housing cooperatives
The AI employee finds housing cooperatives whose roofs are due for replacement based on construction year, typically 25-30 years old. It drafts an outreach letter to the property manager or board chair.
Direct marketing reaches the right targets at the right time.
In practice: a quote for a terraced house roof renovation
A roofing contractor received a quote request for a 1980s terraced house with 6 units, a pitched roof, and existing tile cladding. The property manager sent floor plans and photos.
The contractor forwarded the materials to the AI employee: 'Calculate materials for a sheet metal roof. Current tiles stripped, underlayment and battens replaced. Include eaves and downpipes.'
The AI employee calculated the roof area from ridge to eave, factored in the pitch to get the actual surface area, worked out the linear metres of sheet metal profiles including a 7% cutting waste allowance, then calculated underlayment area and batten lengths. Eave trim, ridge caps, and downpipes were calculated separately.
The quote included an itemized material list, labour hours, crane costs, and waste disposal. The contractor checked the quantities, adjusted the profile selection, and sent the quote the next morning.
Who it works for, and who it doesn't
Good fit
- Roofing and sheet metal companies with 2-8 employees
- Contractors who do their own quoting alongside site work
- Companies that work on both houses and housing cooperatives
- Companies with 10 or more active warranty sites to track
Not the best fit
- Large roofing contractors with their own sales team and estimating software
- Companies that only do emergency repairs with no quoting process
- Roofing materials suppliers with no installation work
Common questions
Can the AI assess roof condition from photos?
The AI employee can spot visible damage in photos: moss growth, cracks, loose tiles. But a proper condition assessment always requires a professional to get up on the roof. The AI helps with documentation, it doesn't replace an inspection.
Does using satellite images actually work?
Google Maps and similar satellite imagery is accurate enough for a rough area estimate. Precise quotes always need drawings or on-site measurements. A satellite-based estimate is useful when a customer wants a ballpark figure before a site visit.
How does warranty tracking work in practice?
You tell the AI employee the site details when a job is completed. It saves the information and sends reminders when inspections are due. You can also enter your existing warranty sites in one go, and the AI employee builds a tracking list from them.
Try it for 7 days, risk-free
No lock-in, no hidden fees. If the AI employee doesn't work out, you get your money back.
