How much to replace a roof?

Question

How much would a complete tear down be on a 2,000 sq ft 2 story house? How much is material and how much is labor? Can you DIY?

Answer 1

Depending on age of house, how many layers you have, 1 or 2 story, how many valleys and the pitch of the roof itself, even the area you live will determine as well as materials your looking to install. also the quality of the materials themselves, you can get 20 yr warrantys to 50=year warranties on shingles.
roofing can be simply figured by the square(100sqft, or 10'x10' area) for 3 tab composition shingle, its about $40.00 square, the labor arranges about $35.00 square, again depending on what that person has to do and area as well.

Answer 2

What you should do is call 3 or more roffing co.s for an estimate. These are free. Now compare what you can get the material for at a home store. Now subtract the amount of materials from the bids and you have the labor cost. Just keep in mind if you've never done a roof before, that the labor cost also guarantees that the project will be done in a timely fashion, and correctly. Keep in mind the cost of hauling a dumpster full of old shingles, and other debris. The chance of wet weather while the home is vulnerable. If you do it yourself, you also have the cost of tools, ladders, meals and refreshments for the volunteer help. If you have done a roof or two before, go for it. If you havn't, reconsider the estimates.

Answer 3

The cost depends on the square footage of your roof, not the square footage of your home. It also depends on where you live, the type of roofing, replacement of boards, etc.. Plan on about 1-2 days for a contracter to do it for you.
You can DIY and save a lot of money but you will need to read up on it or at least have a friend who is knowledgable in this area. Call roofing contracters and get a few estimates, that will help.

Answer 4

You did not state where you are located. Prices vary from location to location. Unknown: style of roof, valleys, slope of roof, etc.

Cannot give a ball park price for renovations; especially without seeing the job.

You can DIY but how are you on heights? It may not look high from the ground, but many people freeze when going above 10 feet on a ladder.

If the pitch of the roof is steep, a contractor would be the best way to go.

When you DIY there are no guarantees: Read on.

Have the contractors remove the old shingles and dispose of them. 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 new 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 pitches 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.

My roof was about $14,000 for about 4500 Sq Ft with multiple pitches, 6 valleys, 3 roof to verticle wall flashing, 1 roof to roof flashing (two very different pitches)
Large portion of roof over 35 feet from ground.
==============================
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

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, make sure they are fully licenced and insured, 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.

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.

8/ Do this until you have selected at least 3 contractors.

9/ Read over the estimates and have someone check the who has some knowledge of this type of work.

This may take longer than you thought; do not rush into it. Research, resaerch research, helps. then make your decision when you are more informed.

Good Luck

Answer 5

2000 square feet..2 story houses don't have as much roof space as a 1 story of the same size. Don't know wher eyou live. As long as the decking is ok and you just need to tear of to the decking and reshingle..probably looking at approx. 4 to 5 thousand.

Answer 6

I'm not a contractor, but I've worked with some. This sounds like at least a three man job, and depending on how fast they work, around 3-7 days. I can't speculate on cost, but I doubt it's a cheap job.

Answer 7

well i kno itz over 100..
