If you are a property owner with minor issues or leaks, which typically occur as the roof reaches the end of its lifespan, but the roof is in overall good condition, re-roofing could be the best option.
If you only have one layer of asphalt shingles on your roof, you may also be a good fit for re-roofing. However, if only a portion of the roof needs to be restored, you may not want to go for re-roofing because only doing one section of the roof may cause it to be uneven in some sections, which may not look the best.
