Obvious and Hidden Causes of Roof Leaks in Denver

Obvious Causes of Roof Leaks

>

  • Storm damages shingles. After a large storm, it’s common to find shingles that have blown off your roof. This often happens because as shingle age, they tend to weaken. This causes shingles to break where the upper shingle makes contact with the single below it. If you find shingles that have blown off after a storm, we suggest you contact a roofing professional to have your roof inspected.
  • Sun damage to wood shakes or shingles. Over time, the sun can age wood shakes or shingles to the point where the sun actually can burn through the felt paper below. If this is happening on your roof, there is a good chance that your roof will need to be replaced. Unfortunately, once your roof gets to this point, it is generally not reparable.
  • Materials have failed. Sometimes, even though the roof itself is still in good condition, some of the materials may be failing. This can be caused by materials failing over the whole roof or just in certain areas. The problem is most common when shingles were not installed correctly or have failed ridge/hip shingles. A roofing professional can determine the extent of the damage.
  • Debris build-up. It’s very important to keep your roof clear of debris. This is because if debris builds up, it can trap moisture and potentially cause your roof to leak. The most vulnerable areas of your roof are valleys (behind skylights and chimneys) and anywhere that water doesn"t freely run off the roof.

Hidden Causes of Roof Leaks

  • Improperly flashed vents or jacks. We see this problem with the installation of new hoods for ovens, furnaces or bathroom fans which require cutting through the roof. If you have any of this work done, we suggest you contact a roofing professional to ensure that the work was done properly.
  • Satellite dishes mounted on the roof. We advise that satellite dishes be installed on a gable or rake edge rather than directly onto the roof to prevent leaks. If the dish is mounted directly to the roof, often no sealant is used or soon enough, the sealant that is used dries up and is no longer effective. If you do get a satellite dish installed directly to your roof, we suggest that you contact a roofing professional to do a visual inspection prior to the rainy season.
  • Worn out tape or rubber seals on plumbing jacks. A visual inspection often reveals that the tape used to seal the gap between the pipe and the jack flashing has dried up or disappeared. Other failures are found on flashings with rubber seals.

You may be tempted to inspect your roof yourself, but safety must be your top priority. We suggest that you contact the professionals at Denver Contractors, Inc. if you have any concerns about roof leaks. The cost of a calling a professional is definitely worth it to preserve your safety!
