About us

your estimating partner

We know from experience how much time and effort goes into creating and collecting prices for construction projects. Your time is much better spent securing and managing contracts. This is especially the case for smaller projects where typical quantity surveyors are often too expensive.

1Roof specialises in providing quick, accurate and cost effective estimates for developers, architects, builders and homeowners. From initial ballpark estimates to detailed schedules and complete quotes, we work closely with you to validate your rates, build up a picture of your business and clients over time and develop a relationship which results in more successful projects and better use of your time.
