In 2009 we installed a CertainTeed Presidential premium asphalt shingle roof and copper half round gutter in Park Ridge IL. This project was a new construction on a very upscale home.
The shingles were installed, but first ice and water shield at the gutter lines and all the problem areas including the valleys and the many flashing areas such as where the roof meets the wall and around the chimneys. we install a premium 30 Lb asphalt saturated felt paper and all copper flashings.
There are low slope areas, not really visible in the pictures, but a color coordianted 4-ply granulated modified bitumen roof system was installed in these flat areas. We wanted to ensure that the flat roofs would last as long as the shingles.
All the flashings and the gutters are 16 0z. copper. The gutters are half round style, very beautiful!
