Maybe instead of a full rebuild, have you thought about just a modernization of it's look.I did a mockup of Hardie board, a porch with a trendy standing seam metal porch roof, new doors and windows, architectural shingles, roof ridge vents, and stone cladding around the foundation.The house looks small and it's only one story, have you thought about teaching yourself to put on the Hardie board and save same money.But there is a lot of extra land, and the neighbors houses do look a lot bigger though.Decisions, decisions.Just my 2 cents.

The owner said it needs new shingles.

Things your contractor should know: there are no 2x4s in the place, the switches and outlets don't have standard boxes behind them, the subfloor in the bathrooms almost always needs to be redone, the cabinets can't hold granite unless you built a support structure, support under the house where there are tubs, and the roofs cannot have more than one layer of shingles. 

I.e a roofer just lays shingles every day and knows the tricks.Always ask for a insurance cert and verify it with the company.

Depending on roof type, materials used, amount of wood repairs, any extra things like flashing replaced or stucco work, you can expect to pay between $9,000-$12,000 for a 20 square new shingle roof in FL, on average.

Hello BP family,I'm in contract for a home built in 2021, upon the home inspection it was found that about 1/4 of the roof has these defected shingles that have a line/minimal crack through them.

Also avoid putting a new layer of shingles on over the top as they will often do.

You get three quotes based on roof line complexity and square footage, putting on a new layer of shingles versus stripping it all off and putting on new plywood.

Not a full roof replacement. 4 spots where there are torn shingles.
