Winter Checklistby Bruce Cunningham Preparing roofs for winter is a task often overlooked by many building owners because they believe if the roof is not leaking, there are no problems. Checking roof areas for the following items before snow, high winds, and other associated winter weather problems set in may prevent costly leaks during adverse weather conditions. Active Leaks - A qualified contractor should be notified to make repairs as soon as leaks occur. If the system is under warranty, the manufacturer should also be notified of any leaks.Field Membrane - Walk over the roof area to see if anything looks out of place, such as blistering, ridges in the membrane, eroded areas, misplaced ballast, or misaligned or loose pavers. If these deficiencies are occurring, they should be corrected as soon as possible by a qualified contractor.Perimeter Flashings - The perimeter flashings should be checked for securement and any openings that would allow water to enter.Penetration Flashings - All penetrations should be checked to ensure they are sealed and secured.Roof Related Sheet Metal - All roof related sheet metal should be checked for securement, sealed joint laps, and missing components. These items could cause problems during winter months.Drainage - Poor drainage is one of the most common problems during winter months. The following items should be checked:r Make sure all drains are open and allowing water to exit.r Clean all debris in and around drains that could clog strainers and restrict water flow. r Check gutters and downspouts to make sure they are secured and that all debris is removed. r If heat tapes are in place in the gutters, downspouts or drains, make sure they are in working order. Miscellaneous / Adjacent Conditions The following items are also often overlooked prior to winter setting in, and should be check for any deficiencies: r Ductworkr Door seals r Open joints in walls r Skylights r Penetrations through walls By making sure all these items are checked prior to winter, building owners can save themselves a few headaches and money. It's usually more costly to hire a contractor during winter when it's more difficult for them to find and repair problem areas. |
