For the roofing experts - I bought a mobile home on the main ranch where I hunt and work sometimes in South Texas.
Currently it has asphalt shingles. They are patchy in spots where wind blew some off, but there are no big bare spots. High winds, 50 - 60+ mph are common every year.
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.
Not into it, THROUGH it, and all the way through the decking, too.
With only 1 layer of shingles, especially if they're 3 tabs, weight won't be an issue. The metal isn't enough added weight to matter.
