Bergen County Roofing: Article About Problems Under The Shingles
There is more to installing a new roofing system than just shingles and nails. A roof is more complicated than it seems at first glance. Chimneys, valleys, flues, flashing and other elements of a total roofing system all come into play to ensure that your roof sheds water and keeps your home, family and possessions secure and dry. Bergen County roofing professionals will consider all of these factors and work to perform quality repairs.
If your current roof has one or more layers of shingles on it, the installers may recommend tearing off these layers before the new roofing material is installed on the home. The roofers will then be able to see the underlayment and roof decking underneath these layers of shingles. Depending on the condition of the decking, it may need to be replaced. In some cases, small holes in the decking can be patched with metal or other materials. If significant damage has occurred, an entire replacement may be needed.
Your roof has various vents, flues and chimneys that extend above the roofline to remove heat and/or potentially dangerous gasses from your home.

The areas around these pipes should be examined to ensure that there is no possibility of water entering through the openings around the pipes. These areas can be covered with a piece of metal known as flashing and/or covered with caulking for waterproofing purposes. If you have gas appliances, your flue vent pipe carries dangerous carbon monoxide gas outside your home. It is important to make sure that water doesn't get inside this pipe and hinder the integrity of the flue.
If you have a brick chimney, it should be inspected to make sure it is structurally sound. If there are points where the mortar is weak, the chimney could collapse or bricks could come loose and fall from the structure. Any points of weakness in a brick chimney should be repaired. With older chimneys that are no longer in use, taking the chimney down below the roofline is also an option. This would eliminate the risk of the chimney collapsing and damaging your roof without having to invest in repairing a chimney that is no longer in use. Once an unused chimney is taken down below the roofline, decking can be laid down and secured to cover up the hole. Then, shingles or another type of roof covering can be installed over the spot where the chimney was.
