There are multiple ways of installing a metal roof over shingles. The first one is the direct installation of a metal roof over the old shingles. The problem associated with installing metal roofing directly onto the old roof is that you might ignore the roof problems hiding underneath, which can harm the structural integrity of your roof and result in mold and leakages in the future. This can result in different metal roof over shingles problems including the damage to its components or even a roof collapse can take place as a resultant effect of poor roofing installation.
The second method of installing metal roofing is by starting with a tearing process to avoid metal roof over shingles problems. Firstly, the worn-out shingles are taken down by expert roofers. Once the tearing process is complete, an underlayment is installed over which your new metal roofing shingles are installed carefully. Although, this is a durable roofing technique this still requires a lot of time and modern equipment along with professional assistance which makes it a bit costly and time-consuming.
The last method of installing metal roofing involves the installation of an underlayment directly onto the existing shingles and then covering this membrane with metal roofing as another layer on top. This process is cost-effective and far more substantial than directly installing your metal roof over the old shingles. Moreover, it prevents the effects of contraction and extension of your metal roof due to changes in weather conditions and enhances its lifespan. The protective membrane installed underneath also prevents the moisture from seeping into the roof which further protects your roof from all sorts of roof-related issues and leakages.
All these methods of installing a metal roof on existing roof shingles demand a different amount of effort and time depending upon various factors. The cost of installation and service charges may also vary according to the preferred roofing procedure that is to be followed as per the rules and regulations set by your local authorities.
