About how much will it coast to re-roof a roof on a house?

Question

UM IT HAS A PEAK DOWN THE MIDDLE WITH A PEAK GOING IN THE OPPISITE DIRECTION IN THE FRONT ONLY HALF OF THE ROOF NEEDS TO BE COMPLETLY TORN OFF AND REBUILT SOME DAMAGED DONE WHEN KATRIANA HIT AND GOTTEN WORSE AND IT STARTED LEAKING

Answer 1

This completely depends on the house. Is it a plain peak, or are there a lot of small porch roofs or dormers? Is it leaking now? Does it have to be torn off and completely redone, or does it just need re-shingling?
Most roofs would be $5,000 to 10,000. I suggest getting a couple roofing companies in, most of them will check it out & give a free estimate.

Answer 2

I suggest that you have the whole roof done.

Have all the shingles removed.

Have the contractors remove the old shingles and dispose of them. You may find it is not worth the money saved by doing it yourself. A good and reputable roofing contractor brings in a disposal bin, tarps, and has the proper tools to remove the shingles

Have the old roofing removed. In some areas it is required. Most shingle manufacturers do not guantee their product if the noew shingles are installed existing shingles. This is not widely known. You often have to go to their website and dig, read, dig, read, dig read, ......; there is usually a disclaimer somewhere stating this.

It is a good idea to have felt paper install on the roof under the shingles. This is required by the manufacturer for some slopes otherwise the warranty is void.

In most areas it is required to install a ice and water barrier from the facia (edge of the roof) to at least 2 feet past the inside of the warm side of the outside wall and on low slope roofs.

Here is a link that discusses different types of venting and ice and rain shild

Roof venting

Free Flow Ventilation: 1 sq ft of effective ventilation for every 150 sq ft of attic floor area.

Roof Ridge Ventilation: 1 sq ft of effective ventilation for every 300 sq ft of attic floor area.

I usually calculate it by roof area instead of attic flor area which give much more effective ventilation.

I highly recommend Roof Ridge Ventilation along with good ventilation along the eaves. Make there is good air flow from the eaves into the attic. You must have a full ridge on the roof; not effective on cottage style rooves.

Selecting contractors:

1/ Look up local contractors first. work out form the closest
to your location. If some you trust has had work done
similar to yours, ask them about the contractor they
used. If they were completely satisfied with their
contractor(s), ask for their telephone number.

2/ Select at least 5 your are interested in.

3/ Do a google/yahoo search on each of the contractors
you are interested in; look for praises (check who is
writing the praises to see if they have any connection to
the contractor work in groups> google/yahoo search the people giving
the praise or references)

4/ When you are satisfied with at least 3 contractors,
have the give you written estimates with details of work
to be done, terms, guarantee(s), cost of extras (how
much do they charge if they find something not covered
by the contract), paymant schedules if necessary and
whatever else you can think of to protect yourself.

5/ If the contractor tries to pressure you into signing the
contract immediately with a high deposit (more than
15%) reject that contractor. Be careful, high pressure
can be someone who sounds very convincing, but has
many reasons why you should sign on the dotted line
NOW. Politely and firmly ask them to leave.

6/ It is always good to have another adult with you when a
contractor inspects the work to be done.

7/ If you do not get at least 3 written estimates signed by the contractor - not you (do not sign yet) , go back to 1.

Continue until you get 3 written at least estimates.

This may take longer than you thought; do not rush into it. Research, resaerch research, helps.

Good Luck

Given that this question is open to anyone in the world you might want to be a bit more specific.
What country , state you are in. Size of house, what material you require etc..
