Excellent Roof Replacement guide! Would you recommend doing this as a DIY project or hiring professionals for a home our size (about 2,000 sq ft)?
Just finished our Roof Replacement project and wanted to come back to say THANK YOU. This guide was our blueprint from start to finish.
Did our Roof Replacement project last summer using many of the tips here. The permit section was a lifesaver – didn’t even know we needed one until reading this!
