Loosen and remove the damaged shingles.
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.
Loosen the adhesive underneath the tabs of the damaged shingle then pull them free and discard.
Lay the shingles down so that the bottom edge just overlaps the vertical cutouts.
