I can get it fixed for $5k and you price it $8k because the $8k shingles and company "are better" or whatever and thus you think you can sell it for more.  

In mass, a typical cost for contractor grade strip and re-shingle with flashing and ridges is  300-400 a square. (100 sq ft).

There are other options such as; solar shingles and purchasing the solar system outright.

.#3 Contact Local Contractors for Labor Pricing / Hire a GC to ConsultCall local Subcontractors and get budget pricing for common repairs on your typical rehab project.For example, call a roofer and ask what their average cost per Square of Architectural Asphalt Shingle Roofing would be on a 1,500 sf house, with a 6/12 pitch.Note: Some contractors will be reluctant to share pricing without seeing the property, but tell them you are just looking for a rough budget number you can use on future projects.You can also pay a General Contractor a consulting fee of a couple of hundred dollars (per house) to walkthrough a few properties with you and provide a detailed estimate of prices that you can use as your 'menu for future projects.#4 Compile Your Prices into a Spreadsheet or Estimating SoftwareOnce you start to get a better understanding of Labor and Material costs you will want to store this data into a spreadsheet or software that you can use to help you streamline the estimating process.The Book on Estimating Rehab Costs comes with a spreadsheet that you can use to help you populate your own database of labor pricing and material pricing.

Hi-I'm looking for a roofing contractor to perform some roof repairs on my existing shingle roof and low slope flat patio roof.

There were some shingles that blew off and a leak. 

I just wrecked my truck and a brand new borrowed trailer and insurance did not cover any of it or the 3,300 shingles I spilled across the interstate. 

The truck has a 460 motor and is great for pulling trailers of shingles, my horses, etc. 

Maybe for composite shingles roof how much it would approximately cost per sq. ft.thanks.Harris
