Rockland Ma June 2019 New GAF shingle roof installation, 50 Year non prorated Warranty.
New Roof and Gutter installation.
Aside from the aging red 3 tab shingles, everything looks pretty normal. But this homeowner has leaks when the snow is piled up in this transition between the rubber roof and the shingle roof. 3 things going on here, you can see the ice and water shield under the rubber it has the yellow line going across. If this were a shingle roof application only, it is where it should be, a little higher would be nice. Then the tar paper did counter flash (layover) the ice and water shield as it should, it just should have been higher for better protection against backups under the shingles. The rubber is just sitting there with nothing counter flashing it, just waiting for ice and water to back up under shingles and flow right underneath the rubber and into the home.
The before picture of the roof shows an important area of needed attention where valley, gutter, and roof come together. The other before picture of the old chimney highlights another quick fix roof cemented chimney with torn lead flashings in the front. The chimney itself is bad shape and had to be rebuilt with new lead flashings. Notice the shingles behind the chimney the slots dont line up, common mistake when you dont carry your vertical lines across when installing 3 tab shingles, and is often hidden behind skylights and chimneys as seen in this picture. We installed a new roof completely, with a rebuilt chimney, and its new lead flashing. Along with a new ridge vent, and premium ridge cap shingles. Shingle is GAF pewter grey. The gutter system was reinstalled after being removed to properly flash, and shingle where gutter and roof intersect. The Downspout was reinstalled after porch roof shingles were finished.
We caulk the back of all our gutters when installing, this prevents any overflow behind the gutter, which in snow conditions will cause icicles to form between back of gutter and fascia boards. When finished, they look great and are nice and tight! On the before picture showing black roof cement smothered around the chimney, if you see this on your chimney new lead flashings are a must. This really should have been done on the last roof installation. New roof, why not new lead flashing?
