The 7-Step Cost-Control Checklist for a Florida Tile Roof (or Any Tile Project)

When to Use This Checklist

If you’ve ever sent a tile request to three suppliers and compared only the bottom lines, you know why this checklist exists. I’m a purchasing manager for a construction company in West Florida. For the past seven years, I have tracked a little over $2.1 million in tile and roofing purchases in the same cost system. I’ve ordered through florida-tile’s commercial team, regional distributors, and direct importers.

This checklist is not about aesthetics. It is for a 22-square tile roof replacement, a 4,000 sq ft porcelain lobby, or a small backsplash behind white kitchen cabinets. All of them create the same problem: comparing a real total to a number that is missing something.

Fundamentals have not changed. The lowest unit price is not the lowest total cost. But execution has changed. In 2025, a supplier who is 1,500 miles away can be the right choice—if you check the logistics. What worked for a local order in 2020 may not work for a long-distance delivery in 2025. Use the checklist before sending the PO.

The 7-Step Checklist

Use these steps in order. Skip the first one and you end up comparing ideas instead of offers.

1. Lock down the written specification before you ask for a price

If you ask for a Florida tile roof or a white porcelain wall tile, no two suppliers will give you the same offer. Every supplier will choose a different product or a different installation method. That quote means nothing.

Create one document with product name, manufacturer or trade equivalent, series, exact dimensions, finish, color, edge treatment, trim pieces, square footage, and the installation method you expect. For roof tile, add tile profile, hip/ridge/rake accessories, attachment method, and any manufacturer installation requirements. For a kitchen with white kitchen cabinets, state whether the tile is wall tile, floor tile, or both. Write down the location. A glossy 3x12 tile on the wall is not necessarily the right material on a shower floor or a countertop.

Checkpoint: all suppliers quote from the same written specification. If they suggest a substitute, ask them to confirm it in writing before you change the spec.

2. Measure the real field, then add waste and dye-lot margin

A cost-control spreadsheet cannot fix a wrong quantity. Use actual site dimensions or final shop drawings. Do not rely on the square footage number from an estimate that was written before anyone measured. Add 10% waste for a basic wall tile layout, 15% for large-format or diagonal floor tile, and at least 10% for roof tile to cover cutting and field breakage. If the roof has hips, valleys, and penetrations, get the roofer’s waste factor in writing.

Then ask about dye lots and batch numbers. If you need 1,000 sq ft and the supplier has 900 sq ft in stock, the remaining 100 sq ft is not a match until it comes from the same lot. Whether you buy from florida-tile, a local dealer, or an importer, this rule is the same.

Checkpoint: the order quantity includes waste and is expressed in the same unit as the supplier’s price. Convert boxes, pieces, square feet, and roofing squares before comparing.

3. Convert every quote into a line-item total cost table

It is tempting to think that a low price per square foot is the only number you need. It is not. The material price is just one line in the real total. The real total includes delivery, freight and fuel surcharges, truck type, liftgate or boom service, taxes, disposal of the old tile or roof, underlayment, fasteners, trim and edge pieces, permit/inspection costs, temporary site protection, and the cost of a crew waiting for late material.

In Q2 2024, I compared two quotes for a 22-square tile roof in West Florida. Vendor A’s tile price was $3.12 per sq ft lower than Vendor B’s. On 2,200 sq ft, that looked like a $6,864 advantage. But Vendor A’s quote did not include delivery, ridge accessories, or removal of the old roof. Vendor B included those lines. After I itemized Vendor A, the real remaining advantage was only about $1,100, and its delivery date was six weeks later. I went back and forth for a day, then chose Vendor B. I immediately worried I had left money on the table. It was the right call: the roofing crew stayed on schedule and the change-order risk stayed low.

This is not a warning against lower-priced suppliers. It is a warning against comparing different things.

Checkpoint: you can explain what each line item covers and what total cost you are approving.

4. Put availability and delivery dates in writing

A great price means nothing if the material is not available when you need it. Ask for a confirmed inventory date, not a probably date. Ask whether the tile comes from the manufacturer’s stock or from the supplier’s own inventory. Ask for the lot number and current photos if the material is coming from a remote warehouse.

If the supplier controls the logistics, include the ship date, expected delivery date, carrier, freight class, receiving hours, unloading requirements, and who is responsible if the shipment arrives damaged. A delivery delay is where budget overruns go to hide. Period.

Checkpoint: the delivery date is part of the quote. If the quote says TBD, your schedule is not protected.

5. Verify the installation system and warranty before comparing warranties

A tile roof is a system, not just the tile you see from the street. In Florida, the roof assembly must satisfy the wind-load requirement in the current Florida Building Code. Ask the tile supplier for the manufacturer’s technical data, installation instructions, and code report for your wind zone. If a salesperson says the crew has always done it this way, that is not a specification. The Tile Council of North America publishes tile installation methods in its TCNA Handbook; use that language when you write the bid package.

For floors and walls, ask the same system questions. What substrate is included? What mortar or adhesive is in the quote? Is there waterproofing where needed? Are expansion joints accounted for? What happens if the tile installation fails—does the warranty cover the tile only, or labor as well? A roof tile might last 50 years. The warranty terms still need to be written in the contract.

Checkpoint: the installation method, substrate, and warranty are named in the bid documents, not described verbally.

6. Plan removal, site access, and staging like it is part of the install

For re-roofing, removal and disposal are never free, but they disappear when people compare material prices. Ask whether the old tile can be recycled, whether a dumpster is included, where the dumpster will sit, and who obtains any disposal permit. Confirm the same for a tile floor tear-out.

For every job, ask whether a pallet of tile can reach the work area. Can the delivery truck fit? Does the quote include a liftgate? Who brings the pallet jack? If white kitchen cabinets are already installed, protect them. Dust control and cabinet protection are real costs. If they are not in the quote, a change order will add them later.

Checkpoint: the site conditions and removal costs are in the written scope before the crew arrives.

7. Audit the final invoice line by line

The last step is the one most buyers rush. I have tracked every order in the same procurement system for seven years. Last year, I found at least one discrepancy on one out of eight deliveries. The usual causes were freight charged twice, a restocking fee that was not in the accepted quote, or a price updated after a verbal change order.

When the invoice arrives, compare it to the accepted quote and the PO. Do not pay a disputed invoice just because the project is behind schedule. That is exactly when handling fees appear.

Checkpoint: there is a written trail from spec to quote to purchase order to delivery receipt to invoice.

Mistakes That Still Blow Up Tile Budgets

• Comparing only the tile price. The lowest tile price can still be the most expensive order if freight, accessories, substrate, labor, and delays are not in the comparison.
• Ordering exact numbers. You will need extra pieces for cuts and breakage. Reorders from a different dye lot are a visible seam no budget can hide.
• Assuming local is always faster. That belief comes from an era before real-time inventory and consolidated logistics. Today, a distant supplier may have the actual stock while a local dealer has only a sample board. Judge by confirmed inventory and delivery dates, not by zip code.
• Accepting value engineering without a new spec. If someone changes the product to reduce price, the substrate and installation details may have to change too.
• Trusting verbal change orders. A change order is only real when it is written and priced.

Bottom Line

The tile industry changes. What was best practice in 2020 may not fit in 2025, and the best practice in 2025 will probably not fit in 2030. But the fundamentals have not changed: a low price is only useful if it covers the right product, the right system, and the right delivery schedule.

Use this checklist on the next Florida tile roof, floor tile, or white kitchen cabinet project. If a supplier gives you clear line items, real lead times, and current technical data, you can work with them. If the answer is do not worry about that, that answer is not a quote. It is a sales pitch. Your budget deserves better.
