Here is a picture of a roof that is about to be replaced. Follow the pictures and descriptions along the way to understand every aspect of how your roof should be replaced.
All of the shingles should be removed from the roof decking, even if you have two or more layers.
Once all of the shingles are removed; the roof decking should be free of any miscellaneous debris.
Next, you should have Ice & Water Shield installed on the lower areas of the roof along the gutterline. This is the area that is affected the most by ice building up on the roof and water wicking back under the shingles during rain storms. It should be installed from the gutterline up approximately 3 feet. We take this a step further and we install it around all pipe collars before we install new pipe collars. Ice & Water Shield is a protective coating that does not allow water to penetrate it.
A small area of the peak of the roof is cut out for the installation of the Ridge Vent. Ridge vents have taken the place of the spinning aluminum turbines used in the olden days.
Ridge vents allow the attic to breathe. More importantly it allows hot air trapped in the attic during the winter to escape. Without a ridge vent the hot air from the attic would meet the cold air outside and cause condensation and moisture issues under the new shingles. The ridge vent prolongs the life of your roof.
Next the entire roof is covered with at least a 15lb. felt paper and marked off for the installation of the shingles.
