Low Maintenance EPDM Roofs: EPDM is a kind of synthetic rubber that can be used for waterproofing or roof leaks repair of all kinds. The material is commonly used on top of metal roofing found in RVs, trailers and some homes.
There are two forms of EPDM. The foil or sheet form is typically used for waterproofing new roofs. The sheets are often recommended for flat roofs in commercial type buildings. It can be used on trailers and houses too but some people don’t like the appearance.
The other type is a liquid. There are several advantages to the liquid type.
The first advantage is durability. The liquid type may help the roof last even longer because there are no seams that could be a target for water pooling and eventually rust.
An adhesive must be used to install the sheets. The liquid type is a “self-adhesive”. It only needs to dry to hold itself in place.
The liquid is easy to apply. It takes only a single coat. There is no need to use a primer or other coats. You need only ensure that the roofing is clean and dry before pouring on the EPDM.
Both types are resistant to practically any temperature that occurs here on earth. Whether it is 40 below zero or 250 degrees Fahrenheit, there is no risk of melting, cracking or peeling.
The curing time and the temperature needed for curing are considerations for the liquid type. They are not necessarily disadvantages unless you live in a climate that is below 55 degrees day and night year round.
The liquid cures through a catalyst chemical reaction. In order for the reaction to occur, a daytime temperature of 55 degrees or higher is necessary. Very high temperatures could also interfere with the curing process. This is a job best done during late spring, early summer or early fall in many parts of the country.
The liquid EPDM can also be used to repair existing EPDM roofs. If only a small area of the sheeting is damaged or needs to be replaced, it may be more cost effective to use sheeting for repair, as long as you can find a small amount of sheeting. Many hardware stores carry patching kits and you can also find them on the internet.
Very little maintenance is required for the rubber roofing. A seasonal check to ensure that no branches or other debris have deteriorated the coating is about all you need to do.
