I had a water leak in a 1st story bedroom which had a 2nd story above it but also had its own roof (about a meter wide the full length of the home). Called many roofing companies for quotes - virtually all wanted to do the whole roof and many claimed I needed to replace all of the underlying plywood (without even checking). John from Home Matters efficiently diagnosed the problem (shingles damaged by Racoons) did the repair noting that the underlying wood was sound, as well as fixing some other minor issues. Great company - great guy and I would hire them again to replace the entire roof when necessary
