replacing cedar shake with asphalt shingles

I'll be replacing the cedar shakes but am trying to avoid redecking. The deck is currently 1x4's with a 2 inch gap in between... when i was quoted from a roofer he said it'd need to be redecked with osb... however a roofer buddy of mine said on similar homes they've just inserted 1x2's in the gap. Is inserting the 1x2 slats a kosher alternative to redecking the whole roof? and are there any special precautions i should take in doing so?

Redeck it or go with tile, slate, shake, or metal. 2" boards split easily and as a result, lose much of their holding power, and with cracks every 2", many nails will miss completely or just catch an edge and lift back out.

I would never replace shake with asphalt. Go back with metal or another material that will preserve the look of the home.

Can you do it? Yes. Should you? No. Main reason was already stated. The other is by the time you spend the money and dick around with the hours of installing them you may as well have re-sheeted with the OSB.

Agree with WoW. Always a shame to see an alternative roof fall to the asphalt demons.

the problem with using the old lathe is there will be a thousand nail heads poking up thru your new shingles
redeck with one of the aluminum coated OSB's Remove lathe to attain 16'' OC
install sheets perpendicular to lathe (8' legth up ) not sideways
