Synthetic Felt Vs Organic Felt- Pros And Cons
Whenever homeowners think about new roofing, they only consider the outer layer most of the time. However, a roof also requires an underlay placed between the decking and outer material. An underlay is of immense importance as it offers heat insulation, prevents damage to the deck of the roof, acts as a water barrier, and offers additional insulation properties.
Generally, you will be choosing between an organic or a synthetic felt, so make sure that you consider the pros and cons of both before making a final decision.
Pros and Cons of Synthetic Felt
Synthetic underlay is made from a variety of materials including polypropylene, fiberglass, polyethylene, and polyester. It has a number of advantages over organic felt, but do not decide just yet!
Most importantly, synthetic felts prove to be much lighter than organic felt underlay. This means that the homeowner can easily install a water barrier without adding a weight to the roof. The lightweight properties alongside make it safe and easy. The installation process is not a tough job, and it degrades at a slower rate compared to organic felts.
At the same time, synthetic felts are comparatively expensive than organic felts. Alongside, things may go wrong during the installation procedure that may weaken the water barrier. Overall, the most important factor that stops homeowners from purchasing synthetic felts is the local building code so they should ensure that they consider these before beginning the work.
The Pros and Cons of Organic Underlay
Organic felts are prepared using asphalt saturated papers. They are cheaper than synthetic felts but do not lack in any way, proving to be the best option for house owners with a limited budget. The biggest benefit of organic felts is that they are hardly prohibited by any local building code. Alongside, they provide an opportunity for homeowners to install it themselves as hardly anything can go wrong during the installation procedure, hence further cutting down on costs.
All of these benefits make organic felts an ideal buy; however, the installation process often proves to be time consuming. Organic felts are also heavier than synthetic felts and they can degrade faster than synthetic felts. Therefore, homeowners looking forward to install organic felts may have to consider repairing or replacing them after a while.
Considering the basic pros and cons of both organic and synthetic felts, a homeowner should consider all the factors like the local building code, weather conditions, and budget before making a final decision.
