If water has been on a roof for more than 48 hours, it is considered to be standing water. Standing water may seem innocuous, but it is something that can potentially cause thousands of dollars of damage to a roof and home. In extreme cases, standing water may lead to a roof collapsing due to the weight of water that collects.

Flat roofs are the most likely to end up with standing water since they do not have the same level of incline that sloped roofs do. Since a flat roof will normally only have 1 or 2 inches of pitch for every foot of roof, irregularities on the surface of the roof make it much easier for water to collect.

However, even sloped roofs can end up with standing water. Standing water normally collects around chimneys and roof gables, where areas of a roof intersect. Norwalk roofing services can reduce the chances of water building up in these areas by installing roof crickets, which are triangular ridges that are installed in areas where water would normally pool.

Standing water may also collect on a flat or sloped roof if gutters are clogged and overflowing. When gutters are not providing a path for water to flow off a roof, the water may have nowhere else to go and just sit on a roof.

A contractor from Sound Renovation of Norwalk CT roofing companies can answer any question you have about siding or gutters.

One of the main reasons that standing water can be such a problem is that roofs are designed to repel running water. A roof's pitch, hydrophobic shingles and gutter system all work to keep water flowing off a roof. This is because when water has a chance to stick around, it will normally make it past a roof's defenses.

Most roofs have tiny pinpoint holes in them. When water is rushing past, this is not a problem, but when water hangs around, it works its way into these imperfections. From there, the water will normally soak through the roof deck and into an attic. In the attic, water can warp rafters, which are support systems for the roof, and damage insulation.

Standing water can normally be removed from a roof with a water pump or it may naturally evaporate after a few days without rain. However, just because water is no longer on a roof, it does not mean the problem is gone. If the root cause is not addressed, water will continue to collect on a roof when it rains.
