Fixing a badly installed roof will depend on the specific issues with the installation. Problems can vary to a great extent, such as anything from a faulty installation that prevents proper ventilation, to a completely botched roofing job that allows for leakage and poor energy efficiency.

You first have to get the roof professionally inspected to determine what is causing the issue. You may try a visual inspection first, but chances are the problem will go much deeper than what you can uncover without the help of an expert. Some common problems with poorly installed roofs include leaks, improper flashing, or insufficient ventilation.

Next, try to determine the extent of the problem. Once you've identified the problem, assess how much of the roof is affected. Is it a small area, or is the entire roof affected? This will help you determine the scope of the repair and evaluate how much money you’ll need in order to get the job done.

If the problem is related to the installation itself, you'll need to fix the underlying issue before you can repair the roof. This may involve re-flashing or replacing the roofing tiles that were originally installed. After that is done, have a trusted Centennial roofing company repair any damaged areas of the roof. This may involve replacing damaged shingles or patching a hole.

Additional tips include employing a viable strategy of roofing inspections, maintenance and preventive repairs going forward. This will also require hiring one of the best local roofing companies, to ensure that the installation will last in the long run.
