As wood absorbs water it expands.
Roofing in the rain wet wood.
Make sure your roof is completely dry before reroofing.
Wet or rain soaked framing lumber will not rot in a matter of days.
Note that you should never shingle over bare wood like a bird s feathers shingles shed the qwater but are not watertight especially in windblown rain or melting snow conditions.
Homeowners often worry that the wood is ruined if a house gets wet during construction.
If you see that your roof deck is wet warped or wrinkled you should not attempt to reroof.
Not only does this violate building codes but your roof just won t last if installed atop a wet base layer.
Water can cause problems if the lumber is allowed to stay wet for weeks and weeks so do whatever is possible to get a roof on the house.
Know what to look for.
