In some cases, old roofs are not torn down before placing the new one. This is a roofing approach that tends to help homeowners save money, but it has a significant drawback: the roofing structure can become unstable over time, and the construction itself is no longer standard. If the previous owner of your home failed to mention that the roof has actually been re-roofed in this way, you might be at a loss as to what you should do.
In most of these instances, you don’t have anything to worry about right away. Even if the roof was installed in this way, if the job was done well, then there should be no leaks or signs of possible damage that could lead to the need for a complete re-roofing job. That being said, it’s still important to take precautionary measures and make sure you have all the information at your disposal.
A roof inspection by roofing East Lansing professionals is the best course of action you can take. It will reveal whether or not the roof has any points where it’s unstable and where it could succumb to storm damage or present more damage than usual. In some cases, following the roof inspection, you will need to have your roof replaced and the old layers removed – especially if there are more than two layers present.
