It's a 30-yr-old mobile home with two layers of asphalt shingles on it. Other than a little moss, it LOOKS okay: no missing shingles, no raised nail heads, no curling shingles, no gaps around the vents. But I can feel weak places in the roof (plywood, I assume) when I walk on it. I can spot no particular places where water is going in, and there are leak spot on the ceiling of five rooms (scattered). The actual roof is 2,045 sqft.

The asphalt patching stuff, rolled on the whole roof = $1,792.

Snow Roof (needs 2 coats) $2,960. For asphalt shingles they also recommend using their primer, which is extra.

Metal roofing directly from a local producer as a 'kit', and doing it myself = $1,700.

None of this is possible. So, back to the original question: would the sandbags hold the plastic down as well as strips of wood in regards to wind?

(Stapling plastic directly without wood just doesn't work because it pulls loose in a breeze.)
