It is on the west side of South Texas, about 100 miles from the coast. Temperatures are 105 - 110+ in August and September.

With those factors, can gavalume sheets be screwed into the existing shingle layer or do the shingles need to be removed and/or put down furring strips?

This is a camp house, not my residence. So trying to keep a lid on repair costs, but not have the roof leak or blow off.

Thanks guys.

I placed a white steel roof over asphalt shingle with 1" firring strips between on our 1400 sq ft home. I would not change that as the A/C unit works far less now with that extra bit of insulation. I can see no downside to this type of roofing job. It is very commonly seen around here.

People who choose to brew up their own storms bitch loudest about the rain.
