4 Common Roofing Problems You Should Look Out For

Expected or unforeseen – roof problems are always unwanted and can bring along a significant expense.

Unfortunately, these problems are inevitable as the roof ages. However, knowing about the common problems and conditions potentially contributing to premature damage and reduced service life of roofs can help in properly maintaining them.

Without routine maintenance, even the smallest problem can become catastrophic.

Here are the 4 most common roof problems building owners and professionals dread about.

Roof Leaks

Roof leaks are perhaps the most common problem occuring for a number of reasons. Usually, built-up roofs leaks are due to improper fastening of flashing details during installation. Moreover, hot bituminous and torch-applied bitumen roofs may start leaking if a proper moisture barrier is not installed under the coping cap in parapet walls.

Also, with cold-applied modified bitumen, moisture infiltration may result from an improper storage of materials and roof leaks may be due to an under-application of adhesive.

In addition to this, you should consider getting good seams that are either glued together or heat-welded properly to prevent roof leaks.    

Blow-offs, tenting, billowing, and reduced wind uplift resistance

Improper installation of flashing may also result in open seams and laps, which contribute to blow-offs, decreased puncture resistance, and code issues. Additionally, embedding the gravel poorly and using an insufficient number of fasteners in the base sheet during installation may also result in similar issues.

Furthermore, seams made with cold adhesives are beneficial only after the adhesive is cured. If wind and rain target the seams before proper cure of adhesive, moisture can infiltrate the roof or wind uplift can damage its membrane.

Faulty installation and below-the-par workmanship

A poor installation increases the chances of roof problems and decreases the roof’s life expectancy. If the workman does not clean, dry, and prime the area properly before installation, problems with adhesion are likely to occur at some point.

A quality installation is characterized by proper material preparation. Sheets installed without being relaxed or installed in unfavorable conditions, such as harsh temperatures, may result in contraction of sheets, blisters, leaks, or fish mouths.


Minor problems like blistering, splitting, ridging, or surface erosion can eventually lead to bigger issues. While you don’t have to always fix all blisters, one of significant size should not be ignored.

When it comes to hot bituminous roof systems, an improper attachment due to heating of asphalt to an improper temperature, can result in blistering as well as an accelerated aging process and slipping of felts.

Moreover, if the roof membrane is not torched properly while installing a torch-applied mod bit system, it may lead to blisters, delamination, and slipping.

A quality installation, consistent maintenance, and early detection of problems through regular inspections are the key to maximizing your roof’s life.

You are not in control of the roof aging. However, the way you deal with these problems will determine the future of your roof system.
