Loosen the adhesive underneath the tabs of the damaged shingle then pull them free and discard.
How to proceed to change scingles from the house roof.
Doubling up your shingles can save time and expense on your roof replacement as your roofer doesn t need to remove and dispose of the old shingles.
Just remove them and replace them with new shingles of a similar style to the rest of the shingles on the roof.
Work your way up the roof nailing down the shingles with four nails starting at one side and nailing across.
This strategy is convenient for homeowners because the replacement won t take as long or make as much of a mess.
