What actually moves a roofing quote in central Florida
Two bids on the same house can sit thousands apart, and greed is rarely the explanation: they price different work. In this arc the gap usually hides in five places, and every one of them can be pinned down before signing.
The five lines
The layer assumption first. A tear-off priced for one layer that finds two is the most common day-one price move in the trade, and the fix is a sentence: every quote states its assumption and the price if there is another.
The decking second, priced per sheet, because nobody knows how many boards are soft until the roof is open. The hardware third, and on the coastal half of this arc it is a real line: stainless or coated fasteners, new flashings, drip edge chosen for salt air.
The underlayment fourth, because in a climate that rinses every roof daily, the membrane under the covering does the real waterproofing. And the attic fifth: whether ventilation is corrected or merely reinstalled, which decides how fast the new covering ages from below.
Comparing bids that refuse to match
Line the quotes up against those five points and mark what each one actually says. A cheaper bid that is silent on decking and flashings is not cheaper, it is unfinished, and the difference will appear later with worse timing. The comparison tool on this site walks the exercise question by question.
Quick answers
- Why is the same shingle priced differently across town?
- Because the shingle is the smallest variable. Access, decking, hardware and junction details are the job; the covering is the surface.
- Is the low bid ever the right one?
- Sometimes, when it states the same assumptions as the others and simply schedules better. The point is not to distrust a low number but to make every bid answer the same five questions.
