Roof replacement is completely removing and replacing all the roofing materials. In some instances, you’ll have to remove the support structure if your roof is severely damaged and restoration can’t be done.
What’s more, the roof has to have reached a point where switching tiles or shingles won’t be enough. In this case, you’ll have to hire a professional to assess the extent of the damage and the best solution.
Roof replacement is usually required when the roof has irreparable damage. Depending on the severity of the problem, you might have to replace the entire roof.
