Most homeowners do not realize how important it is to check their roof on a regular schedule. The roof is the largest part of the home, and it is subjected to all kinds of weather conditions that can deteriorate the roof. The wind can blow water under the shingles that will rot the decking and then flow into the attic and down into the living areas. The condition of the roof cannot be assessed from the ground; a professional roofer must go up on the roof and examine it for these problem indicators: Curled shingles, Split shingles, Loose shingles, Flashing that is worn; Rotted decking, and Worn or leaking water barriers.
The professional roofer is the person to recommend repairs or a new roof after they have examined the critical areas. If a new roof is required, it is their job to recommend the appropriate moisture barrier, the correct decking if it needs replacing, and the type of shingles that are appropriate for the home’s location.

The roof area around vents and chimneys should be sealed before laying the shingles. The nail heads that hold the vents and flashing in place should be covered with tar for added protection.
