A roofer who wants to put a new roof on my mobile home says it will dry out. (We live in the rainiest part of the US)
It shouldn't need replacement unless it is damaged someway.Like mold,dry rot or UV Damage.He should be willing to explain why and show you the condition of the roof before and after he works on it.
sound like the roofer wants to RIP you off, you Mop or spread a coating not put shingles on it,[A Trailer,] you don,t mess with the insulation, its under the roof. tell him to hit the road he is setting you up for a big mess,
If your insulation gets wet while the roof was removed, you will most likely have mold/mildew problems after the roof is replaced. While the roof is off, it's an excellent idea to inspect the insulation are replace as necessary. If your roofer isn't going to protect your insulation while it is exposed, find another roofer.
I think everyone is misunderstanding your question. I think what you are saying is that your insulation got wet, becasue of your roof leaking. The roofer wants to replace the roof but not the insulation. If your talking about an insulation board under the roof then I think your roofer is right. Just put a new roof on. If you talking about some kind of fiberglass batt insulation then it probably should be replaced.
