What does a price per square metre of metal roof tiles include?

If a second quotation gives the effective cover price, compare it with the converted rate. A lower label price may simply refer to gross area. Ask for the total for the complete sheet schedule since rounding unit prices can produce small differences.

Check whether the finish surcharge uses the same basis as the sheeting. Convert any charges based on overall area and cover area to the same unit before adding them.

For a panel sold by the piece, divide its price by its effective area. At 0.777 m² and an illustrative PLN 45 per panel (€10.43), 45 ÷ 0.777 gives about €13.42 per covered m², excluding VAT.

The roof layout determines how many whole panels to buy. Diagonal edges and valleys require cuts. Check whether offcuts can be used elsewhere in the correct direction. The square-metre rate alone does not establish the purchase quantity.

Colour does not identify the protective coating. Two graphite-grey sheets can have different coatings and warranty terms. Specify steel thickness, protective layer and surface finish in the quotation. “Matt” alone is too broad.

Choose a coating suited to the environment and intended appearance. In industrial, agricultural or corrosive conditions check the permitted use. Read the actual warranty coverage before paying extra for a longer stated period.

Compare two illustrative orders excluding VAT. The first needs 126 m² at PLN 49 (about €11.35) per m², totalling €1,430.66. The second needs 118 m² at PLN 53 (about €12.28) per m², totalling €1,449.20. The totals differ by €18.54, although the unit prices differ by €0.93. Totals are converted before rounding.

These are assumed quantities and prices. Draw a cutting plan for the actual slope lengths, valleys, dormers and laying direction. Excess stock costs money and needs storage. A shortage can mean another delivery and a shade difference between batches.

Itemise sheets, flashings, fasteners and ventilation. Add chimney details, snow retention and service penetrations as required. This makes omitted accessories visible when comparing complete roof packages.

Agree delivery and unloading separately. Long sheets may need a particular vehicle or lifting equipment. A fixed delivery charge has a larger effect per square metre on a small order. Show which prices exclude VAT and how tax is calculated.

Check offer validity, colour availability and production time. Confirm whether cutting, selected services and packaging are included. Self-collection also takes time and transport. Include those costs when comparing online baskets.

Obtain the final total against an agreed schedule and keep the version used for pricing. If sizes or coating change, request an updated figure. This makes price changes traceable and documents what the parties originally agreed.

For separate house and garage deliveries, allocate freight to each. An average square-metre rate can conceal the cost of a second trip omitted from the initial estimate.
