Roof Before and After: A Full Transformation

What a full roof replacement actually includes

• Tear-off of the old material down to the wood decking
• Deck inspection, with soft or rotten sheathing replaced before anything is covered
• New underlayment across the whole deck: the waterproofing layer under the shingles
• New drip edge, flashing, and vent boots, because reusing old metal is how new roofs leak
• The finish layer itself, installed to the manufacturer's nailing pattern so the wind warranty holds
• Cleanup with a magnetic sweep so the yard does not keep souvenirs

Reading a before and after like a roofer

The color change is what jumps out, but look at the lines. Straight courses, a clean ridge, crisp edges at the eaves and valleys: those are the visible signature of a roof that was installed with care underneath too. Wavy courses and lumpy ridges on a brand new roof are a warning that the crew rushed what you cannot see. When you collect quotes, ask each contractor whose crew does the install and who inspects the finished job, because the answer explains photos like these.
