THE PRICE OF CERAMIC ROOFING TILES CAN RANGE ANYWERE FROM 80 TO 200 DOLLARS PER SQUARE DEPENDING ON QUALITY AND THAT IS RETAIL PRICE FROM SUPPLIERS. A SQUARE IS EQUAL TO A 10 FT. BY 10 FT AREA = 100 SQUARE FEET OR 1 SQUARE. AND I BELIEVE THAT TILES PER SQUARE DEPENDING ON MEASUREMENTS CAN RANGE FROM 90 PIECES OF TILE TO 100 PIECES OF TILE.BUT AS YOU ALREADY KNOW YOU NEED AN NOA# OR PRODUCTIC APPROVAL NUMBER. IF YOU HAVE ANY QUESTIONS OR IF THAT HELPED LET ME KNOW. THANKS

In conjunction with Tom Joad's answer - you also have to consider the market. Obviously, California will have higher prices per sq.ft. than Arizona, and I believe Texas will be higher than AZ as well, though not as high as California. Also, what part of CA? Location is the key. Case in point - take Boston. I can say commercial space in the Back Bay of Boston runs an average of $48/sq.ft., yet right down the street in the Theatre District, it runs at an average of about $39/sq.ft. So, be more specific, I guess is what I am saying. Name the market, and you might get a clearer understanding and answer.

You can find how many square feet the kitchen is by multiplying 18*15. This equals 270 sq. feet.  (The * means multiplication)\n\nSince each tile is one square foot, you will need 270 tiles.  Multiply the number of tiles by $18, and thats the cost to cover the floor.\n\nEquations:  \nLength * Width\n\n(Number of Tiles) * (cost per tile)

If you want to build a custom home, expect to pay a minimum of $100 per sf.; more like $125/sf if you want something nice.   If you are talking about a new cookie-cutter spec. home, they tend to start out at around $75/sf, and go up from there, depending on the neighborhood and builder.

$5.15, same as everywhere in the US. that's federally mandated, not done on a state-by-state basis.

Dont' go by anything you read on here. The prices very from state to state. Not a lot but they do. \n\nThe best bet is to call a local lumber company and ask them how much shingles would be for 45 squares, then get a price on architectural, now a days the prices are pretty close to each other. \n\nThen after you find out the price of the shingles you could call a roofing company for a free estimate. I'd call 2 or 3 to see if they are pretty accurate. \n\n*Good Luck*

1 Acre = 43,560 square feet.  An acre can be any length by width as long as the total square footage equals 43,560, if it was a perfect square it would be the square root of 43560 = 208.710326 x 208.710326 feet.

You can use the figure (just an estimate) of about $100 a square foot (bathrooms are a little more).   May be more or less depending on the reputation of your builder and the region of the country you live in.

The south is expensive, no way around it.  For example--an 800 square foot mid-terrace property (that's what a townhouse is in American speak)  in Surrey, about an hour south of London goes for about £175 000.\n800 square feet.  Wrap your head around how TINY that really is. Your house is ELEVEN feet wide. And you have neighbours attached to you.  On both sides.  And no driveway.  \nAre you crying yet?
