Why Is My Commercial Roof Sagging? Common Causes And What To Do
Do you hire an expert to regularly inspect and maintain your roof, or do you assume it's in good condition, provided you cannot see any damage? Roofing issues like roof sagging can sometimes go unnoticed if property owners aren't keen. Such a problem signifies that the roof is in distress and cannot protect the property adequately.
Luckily, a commercial roof repair expert can fix the sagging roof. Once repairs are complete, the risks of roof breakdown or other forms of damage will be reduced. But what makes a roof sag? Here are numerous causes you should know.
Excess Moisture
One of the elements your roof deals with regularly is running water and snow. All forms of precipitation will drain efficiently, provided the roof is in good condition. However, water always finds imperfections in the roof and seeps in to cause damage.
The moisture that accumulates beneath the shingles and the sheathing will create a conducive environment for mold growth and rot. These forms of water damage weaken roofs and cause sagging. A roofing contractor may need to replace damaged sheathing and fix the leaks to restore the roof.
Extra Weight
Is your property in an area that experiences long months of ice and snow? These elements add excess weight to the roof, which may lead to sagging. The ice and snow can cause structural damage if you don't find a way to reduce the load.
Some property owners use a snow rake to remove the excess snow, but this can be risky. The frozen shingles may be brittle, increasing the chances of damage. It's also easy to get hit by falling ice.
Getting a competent roofer to help with the snow and ice removal work is better. They'll eliminate the excess weight to preserve the roof's integrity without causing additional damage.
Old Age
If you want your roofing system to last longer, you'll need to use quality roofing materials and prioritize maintenance. Over the years, however, the roof will deteriorate as it nears the end of its lifespan. So if your roof life is almost complete and it's beginning to sag, contact your commercial roofer immediately.
The professional will inspect it to determine if the roof is too old for repair and, in such a case, recommend replacement. Remember to schedule the replacement project soon, especially if the weather conditions are unfavorable, as you don't know when the roofing might crumble.
Roofs can sag for many reasons, but the key is hiring competent commercial roof contractors to restore them. The roofer will offer customized solutions depending on the cause of the sagging problem. Contact a commercial roof contractor to learn more.
