A homeowner gets three quotations for a roof. They range from a modest figure to nearly double it and all three are from apparently reputable firms.
She cannot tell what accounts for the difference. Two are a paragraph each and one is three pages, and none of them sets out the same information in the same order.
She chooses the middle one, on instinct. It might be the right decision and she has no way of knowing, because nobody has ever told her what a roofing quotation should contain.
Ask 1: is scaffolding included
The single largest variable. A quotation excluding access can look substantially cheaper while representing the same work, and it is frequently the single largest line once it is added back in.
Ask 2: what exactly is being replaced
Covering only, battens, membrane, deck, or everything. Two quotations naming the same tile can involve very different amounts of work underneath it.
Ask 3: what happens with unforeseen work
Rotten timber, a failed deck or something discovered on stripping. Whether it is included, provisionally priced or charged as an extra explains a great deal of the difference.
Ask 4: what materials, specifically
Manufacturer, product and specification rather than a generic description, which is the ground in material choice questions from homeowners.
Ask 5: what is the guarantee and who honours it
Length, whether it covers workmanship as well as materials and whether it is insurance backed. A long guarantee from a firm with nothing behind it is not a guarantee.
Ask 6: who is actually doing the work
Employed staff or subcontractors, and whether the person quoting will be present. This differs between firms and it affects both quality and accountability.
Ask 7: what is the payment schedule
Deposit, stages and final payment. A large upfront payment is a risk and a staged schedule tied to progress is the normal and safer arrangement.
Ask 8: what insurances are held
Public liability and anything else relevant, with evidence. Reasonable to ask and a professional will provide it without hesitation.
Ask 9: what about the associated items
Gutters, fascias, flashings, ridge and chimney. These are frequently in one quotation and absent from another, which accounts for a large part of a gap.
Ask 10: what is the timescale and what happens in bad weather
Including the scaffold position during a delay, because scaffold hire continues while nobody is working on it.
Ask 11: what happens to the waste
Removal, disposal and any skip. Small, always necessary and occasionally left out of a quotation entirely.
Ask 12: is this the right work at all
A repair versus a replacement is the first question and it is frequently skipped, and three quotations for a replacement nobody needs are three wrong answers.
Produce a quotation that answers all of it unprompted
An assistant that captures the property, the roof type, the access position and what the customer has noticed, then explains what a proper quotation should contain, gives a homeowner the ability to compare three documents that currently cannot be compared. The same structured client explanation appears in how financial advisors use chatbots to answer client questions, and the enquiry detail in roofing quote requests that need photos and access. See pricing, run the numbers on the chatbot ROI calculator, and the sector view sits under roofing.
