A commercial roof is one of the key parts of any business property. It serves as a shield from heat, rain, wind, and pollution for the building, equipment, employees, and customers. However, commercial roofs can develop issues as time progresses. Ignoring these problems might result in expensive repairs and may even impact your business. We suggest hiring a trusted local commercial roof repair contractor to address the issues in a timely manner.

​In this blog, we will cover the top commercial roofing issues and simple solutions.

​1. Roof Leaks and Moisture Problems

​Roof leaks are one of the most frequent issues in commercial structures. They typically occur due to damaged roofing materials, cracks in the membrane, or poor installation.

​Water can find its way in through tiny cracks and gradually rot insulation, ceilings, walls, and electrical systems. You’ll see water spots on the ceiling, cracking paint, or a moldy odor.

​How to fix it:

A commercial roofing specialist can analyze the issue and find the source of the leak. Roofing sealant can be used for all small cracks. And if membranes are damaged, they may need patching or replacement. Regular roof inspections can identify leaks before they become major problems.

​2. Ponding Water on Flat Roofs

​Most commercial buildings have flat or low-slope roofs. These roofs can also collect water after heavy rains. Ponding water is a term used when water remains on the roof for over 36–48 hrs.

​Water that ponds increases the weight on the roof and possibly weakens the structure over time. It also risks new leaks.

​How to fix it:

Proper drainage is the key. Ensure that roof drains and gutters are free of leaves or debris and not blocked. Sometimes, adding more drains — or making the roof slope better — resolves the problem. Ponding water will not be an issue in the long run if it is regularly cleaned and maintained.

​3. Damaged Flashing

​Flashing is a metal material that surrounds the edge of roofs, as well as vents, chimneys, skylights, and HVAC systems. This seals the joints and keeps water out.

​As time passes and the elements and temperatures change, flashing can crack, loosen, or rust. When flashing fails, water readily makes its way into the building. 

​How to fix it:

Flashing should be secured and sealed. Rusted or worn-out flashing must be replaced. A reliable local commercial roof repair contractor like 911 Commercial Roofing will inspect around roof openings and suggest necessary repairs for flashing problems.

​4. Roof Membrane Damage

​Single-ply membranes are common in commercial roofs and include TPO, EPDM, or PVC. These materials are sturdy but not indestructible.

​Damaged membranes can result from heavy foot traffic, falling debris, intense heat, or bad installation. You may see bubbles, blisters, cracks, or open seams.

​How to fix it:

Patching and adhesive can repair minor tears. Larger areas of damage may necessitate partial replacement of the membrane. Above all, try to restrict excess rooftop foot traffic and utilize protective walk pads when working near HVAC units.

​5. Roof Shrinkage

​Some roofing materials, particularly older membrane systems, can shrink as they age. Shrinkage will pull the roof away from edges, flashing, and penetrations.

​This has left gaps for water to seep in.

​How to fix it:

Resealing and repairing edges may help if the shrinking is small. In extreme cases, the roofing membrane may need to be replaced. If the house is made up of quality materials, it could also lower the risk of shrinkage.

6. Poor Installation or Low-Quality Work

​Sometimes, roofing issues can begin very early. Not only can poorly installed aggregates lead to an uneven surface, but they’ll also develop weak seams and improper drainage.

​These issues do not show up for several years, but when they do, they can be serious.

​How to fix it:

If the roof was improperly installed, something beyond repairs may be needed. Whether a partial replacement or entire re-roofing is necessary can be detected by a commercial roofing specialist. 

​7. Lack of Regular Maintenance

​Most commercial roofing issues are due to neglect. Business owners tend to overlook the roof until they see a visible leak.

​Dust and debris, backed-up drains, and tiny cracks can gradually become larger problems.

​How to fix it:

​Create a regular maintenance plan. The roof needs to be checked at least twice annually, with a lot of contemplation, just beforehand and right after the monsoon or rainy season. Clear the drains, remove debris, and watch for signs of wear and tear. 

​8. Storm and Weather Damage

​Strong winds, heavy rain, and heat can cause destruction to commercial roofs. Wind can lift roofing materials. Hail can cause dings or cracks. Heat can weaken adhesives, and expansion or contraction can occur.

​How to fix it:

​Check the roof for visible damage after any big storm. Installing weather-resistant materials can also help prolong the life span of your roof.
