I have access to loans at 2%.I have had multiple contractors tell me that my roof will be eligible for an insurance claim due to shingles with storm damage.

Unlikely.80% of our landlords use Excel or bar napkins or some combo. 60% of our small business owners are single-shingle "one man bands," and they too use Excel.QBO, Waveapps, Freshbooks, Stalebooks, SloppyBooks, Xero, One and all the others are nice to have but not must haves until you have several rentals or complex rentals (such as a strip mall or something).

They (ins co's) wanted our industry (Roofing) to come up with better-longer lasting materials, like Class 4 shingles, so they wouldn't have to pay for replacing shingled roofs so often Fine, it happened. 

Similar to if you hired a company to replace a roof-you don't have a copy of the bill for all of the shingles and nails, but you have a copy of their bill that has those effectively built in.

And there were few shingles was missing.as per this condition they cancelled my insurance policy.

It has a typical plywood sheathing and architectural shingle roof.

@Sam P. is it flat or shingled?

Is that Carolina Siding, aka asbestos shingles?

For removing old flooring use a shingle shovel with a sharpened edge.
