Roofs are measured in large squares ... every one large square

equals 100 sqft. I would typically charge $450 per large square to

replace a roof.

There is a wide array of costs concerning roof replacement,

regardless of the area. The material used, size in square footage,

labor costs, and so on. Sometimes a second layer of shingles can be

added, but use caution since you may just be covering up an

underlying issue with the roof structure or mold and algae. In many

cases, when the shingles are replaced, new plywood, tar-paper and

flashings may also need replacement. If the roof is being

completely redone, you may be able to add insulation in the roofing

materials at that time. Due to these factors, obtain estimates from

professional, licensed roofers who physically inspect the

property.

You can save a lot of money by doing it yourself which is not

all that hard!

To measure the roof.(if you can't get on the roof, measure from

the ground like most roofers do.) measure length of building, then

count how many shingles there are going up the roof. The exposed

tab is approx. 6", now multiply by amt. of shingles and divide by

12 to give you the footage up the roof. Multiply length by height,

every 100 sq. ft. equals a square. Ex. 30x15=450sq.ft. or 4 1/2

squares. measure back and front,and add 15 % for waste.

Next, you will need to decide is what roof materials you will

use. If you don't know, you should learn about the different

roofing materials available and make sure that they are code where

you live.

Regardless of how many layers you have you should rip-off the

old shingles and replace the underlayment materials with the new

ones as needed. Go to a roofing supply and price out the shingle

you want and the ice and water shield (prevents water leaks). You

also should install a ridge vent.

The price will vary depending on size, material, location,

warranty, etc. I just did my roof and it cost $5500. I had

estimates from $5500 to over $10,000. When you call a roofer, ask

if he does subcontractor work. You should pay approximately $125 to

$150 per square with you buying the material.

There are websites to find contractors. You put in your project

and several contractors will contact you. You then get to see their

ratings. This may lead to calls from those companies, since the

sites provide them with leads. Usually, 3 to 4 bids will do;

additional ones are likely to be within 5% of each other and you

won't have wasted a lot of people's time. Angie's List is also a

good place to check for recommendations.

Finally, feel free to negotiate. Tell them you cannot afford

their price, and can they cut $XXXX.xx. Or ask for their best

price. Make sure the cost includes protecting your landscaping

around the home and any cleaning up of materials.
