Finding mold in your attic is never a good thing. When it has taken over most of the wood that makes up your roof, that is even worse. Despite the efforts of mold remediation specialists to remove that mold, you might still be faced with having to replace part or all of your roof. Here is how this process proceeds.
Mold Is Removed First
Even if you find that you have to repair or replace a portion of your roof, the mold still has to be removed to prevent it from spreading to the new roof sections and spreading to any older parts of the roof not currently affected. You also do not want the mold spores to become airborne because they can travel to other parts of the house or to your neighbors' homes. Once all of the mold has been effectively removed, then the roofing contractor can begin their work.
Remove the Rotten Wood and Shingles Next
The roofing contractor will come in, verify that the mold has been removed effectively, and then begin removing all of the parts of your roof that had mold and are now rotten and unstable. The rotten wood is thrown into a dumpster, along with any shingles that were installed over the rotten wood. As for the trusses in your roof, they are constructed in such a way that it is easy for the contractor and their crew to just remove certain beams from the exposed trusses and replace those beams to restore the trusses. There is no real need to remove an entire truss unless the entire truss is very old and very rotten.
Rebuild the Roof
All of the parts of the roof that were treated for mold and then removed for rot and age are then rebuilt. This process takes just a few full days of work, but then your roof will be as good as new. Truss parts are replaced as needed, followed by the particleboard that is commonly used over the top of the trusses, and then the underlayment fabric or rubber roll is installed before the shingles. Once the shingles are on, the roof is done.
Treat the New Wood in the Attic with Anti-Mold Spray
When the new section or new roof is complete, have the mold remediation specialist return. They can apply a spray that will kill mold spores on contact so that any free-floating spores still present cannot adhere to the fresh wood in your attic and destroy the new roof. Then the roof is good to go for years to come.
