What are the major differences in installing 30-yr. shingles as
opposed to 20-yr ones? I would like to replace mine with 30-yr. and do
the labor myself but only have experience with the standard flat three
tab 20 yr. style.


Are these 30yr 3 tabbed or architectural? The latter are heavier but you
don't have to worry about the tabs in non-field areas.
