Rotten Decking

When working on your reroofing project, J-Conn Roofing & Repair Service inspects your existing roof to determine any repairs that may be needed. Damage to your roof may have occurred for any of several reasons: a faulty prior installation or use of substandard roofing materials by a previous contractor; fallen trees, rodents; weather events such as hail or wind damage; poor roof maintenance; or the wear and tear that occurs over the normal life expectancy of a roof.

A common cause of roof leaks is flashing, around chimneys or ridge vents, that may have been improperly installed, has degraded over time, or has sustained damage from weather or impact trauma. Old flashing may also conceal underlying problems. Replacement flashings may be made from aluminum or galvanized steel. These long-lasting materials, when properly installed, seal the openings in your roof against moisture intrusion, allowing rain to flow around them and down the roof to the gutters.

The most serious problem that may be encountered during your reroofing project is damage to the decking. The decking may be rotted in places due to water intrusion or sagging. We carefully remove the damaged sections of decking, taking care not to cut or otherwise damage any of the roof supports. We then install new decking, in the same dimensions and thickness as the removed sections.
