Roofing Calculator by is a free flat roof prices estimating tool. Use it for quickly estimate cost of your your flat roof replacement, using following roofing materials: IB PVC flat roofing membrane, EPDM single-ply roof, TPO roofing, Tar + Gravel / Built-up / modified bitumen roofs, and also metal roofing prices for steep slope roof

This Flat Roof Calculator is based on our online roofing calculator - - and work exactly the same, giving you same wide range of roof options to help you estimate almost any flat roof, be it residential or commercial job.

Roofing Calculator has following features, and Roofing Prices are calculated based on user-provided:

- Roof dimensions.
- PolyISO insulation thickness.
- Roof complexity / difficulty.
- Tear off of existing roofing materials.
- Number of skylights / curb flashing on the roof.
- Number of masonry chimneys to be flashed.
- Length of parapet and separation walls.
- Roof pitch / slope (for most flat roofins it will be zero of near-flat - other slope settings are used for steep roofs, such as metal shingles and standing seam).

Roofing calculator uses Progressive Roof Pricing Algorithm which will gradually increase cost per sq. ft. of roof area, for roofs that are 700 sq. ft. or lees in size.

This increase in pricing for smaller jobs, take into account increased job set-up costs and fixed costs (such as insurance, dump fees, job permits, etc) , and lower profit margins, du to smaller overall job sizes.

- - How Progressive roof pricing works - -

This increase in per-square price will be gradual, based on straight line increase to the total amount of $300 / square. For example - for roof that is 350 sq. ft. in size, there will be a $150 added to the base price per square of every type of roofing materials (350 sq ft. is in the middle of the progressive range of 0-700 sq. ft.).

Limitations of progressive pricing and calculator in general:

This calculator may be off the actual job cost, as it is intended to only provide you with ball-park roof replacement cost - not an actual estimate.

Calculator is also based on roof size and information you provide - so if you provide information that is different from what the roof actually is, your pricing will be incorrect.

This calculator is not intended to estimate cost of Flat Roof Decks and IB DeckShield installations ( ). Separate app will be released soon for that specific purpose.
