Signs a Commercial Building Needs a New Roof
Installing a new roof system is one of the biggest expenses building owners face, and an expense some building owners fail to budget for, which leads them to pursue repairs for problems that indicate replacement is what is truly needed. In many cases, there is more than one sign that a roof needs replacement. As it deteriorates, a roof system may have several problems at once, forcing the building owner to install a new system to avoid repairing water damage. Below are several problems that indicate a commercial roofing company should replace the roof of a building, not attempt to repair it.
Screw Holes in Panels Have Widened
Metal roof panels are held in place by screws. Over time, movement in the panels and the aging of the metal causes the holes to widen around the screws. Wide screw holes cause two problems: they allow water to drain under the panels, and they eventually widen enough to let the panels fall away. Replacing the panels before these things happen is a key to preserving the rest of it.
Water Stands Aluminum Corrugated Sheet Specifications on the Roof
Water pools on a roof for two reasons: because a drain is clogged, or because the roof was incorrectly installed. Unclogging a drain is easy, but the only way to fix a poor installation job is to reinstall the parts that went wrong. In some cases, that means installing a new roof.
The Deck Sags in Several Places
The deck is sandwiched between the exterior of the roof and the joists on the interior. When the deck is made of wood, leaks make it sag inward. The more sag there is in the deck, the more leakage the roof experiences. When the problem is widespread and growing worse, having a commercial roofing company install a new system may be the best choice.
Large Bubbles on a Flat Roof
Improper installation and dry lapping cause hot bituminous roof systems to develop large bubbles that are visible on the surface. Tar roof systems commonly develop small, insignificant bubbles in hot weather, but large bubbles can cause problems. In the beginning, the bubbles fill with air, but they may fill with water if a puncture allows water to seep. When they are left unaddressed, water filled bubbles cause water damage to the layers of roof underneath.
Shingles Crack and Curl
Shingles go through a series of changes as they age. The first change is the shedding of granules that fill the gutters. The final change is when the shingles curl and buckle. Because shingles gradually deteriorate, they are not considered repairable, and must be replaced before the deterioration reaches a critical point. When shingles begin to buckle and curl, water has access to the roof layers underneath.

The problems above often signify that a building needs a new roof. If your building experiences at least one of these problems, have a commercial roofing company perform an inspection as soon as possible. Replacing a roof may be costly, but repairing the damage caused by not replacing it could be costlier – and you may still end up replacing it anyway.
