1. Roof Leaks

A leaky commercial roof is one of the most common problems that Denver roofing contractors see. Preventative maintenance can help offset this risk and acting quickly when you notice a leak in order to prevent the further spread and potential damage is crucial.


2. Poor Workmanship

A faulty installation or poor quality workmanship will increase the likelihood of issues and reduce the life expectancy of your commercial roof. When choosing a Denver roofing contractor for your commercial roof installation choose a reputable contractor with a proven track record of quality work and customer service.


3. Improper Materials

Using the improper roofing materials for a particular climate, building structure, and even building usage can cause major issues. Make sure you choose a Denver roofing contractor with experience in both the Denver Metro and the type of projects you are requesting.


4. Lack of Maintenance

To maximize the life expectancy of your roof a preventative, routine maintenance plan is a critical component of building upkeep. When building owners fail to regularly inspect their roofs or act quickly on necessary repairs, they risk small issues turning into larger ones. Work with your Denver roofing contractor on a customized maintenance plan for your building.


5. Blow-Offs

High wind uplift like we sometimes see during Denver storms can cause roof blow-offs. This occurs when winds hit the side of a building and then continues over the top. The space created between the moving wind and your roof can cause a suction effect, pulling weak materials off. Quality workmanship and materials can help mitigate this risk.


6. Pooling Water

Pooling water on flat, commercial roofs is common when drains are clogged or the roof was designed incorrectly without a high enough pitch for proper drainage. If you notice pooling water is an issue, schedule a Denver roofing contractor to clean your drains and inspect for further problems.


7. Punctures

One of the great things about flat commercial roofs is that they lend themselves to space utilization. While this enables building owners to maximize space efficiently, it also means the roof is heavily trafficked. Walking on the roof can cause punctures and tears in the membranes, damaging the structure. Always exercise caution when walking on your roof and only do so when necessary.


8. Damaged Flashing

Flashing is installed on walls, curbs, and around objects such as the chimney to help deflect water from roofing seams and joints. Improperly installed or damaged flashing is one of the leading causes of roof leaks.


9. Incorrect Repairs

If a repair is done incorrectly through faulty workmanship or incorrect materials, this can turn a small problem into a major one. To help prevent this always work with a licensed Denver roofing contractor with a strong industry reputation.


10. Shrinkage

Certain types of commercial roofing materials can expand and contract with temperature changes. This expansion and contraction can cause your roofing structure to warp over time, breaking joints, and causing leaks. Regular inspections will help you catch shrinkage early on and allow proper remediation.



Regular roofing inspections and maintenance are the number one ways to ensure early detection and repair of all of the above mentioned problems. If you are overdue for your roofing inspection, call our team at PRQ Exteriors to schedule your free commercial roofing inspection today!
