EPDM Roofing - Flat Roof Replacement

What is EPDM (Ethylene Propylene Diene Monomer) roofing?

EPDM Flat Roof Replacement Toronto

One of the most popular commercial roofing options is EPDM roofing. Epdm roofing systems are lightweight and simple to install. It is a single-ply membrane like TPO and PVC made of synthetic rubber which has been improved over the years so that current EPDM roofing systems are incredibly durable, tear and highly puncture resistant while maintaining flexibility. EPDM roofs have superior resistance to extreme heat and fire, and ultraviolet radiation.

This type of roofing system is applied using a fully-adhered glue system, loose-laid with gravel or mechanically fastened. None of which require an open flame. The use of adhesive and nails to install results in the environmental benefits being reduced emissions from the amount of equipment needed to install it, there are fewer petroleum based product s and less landfill waste.

When proper insulation is used EPDM can also help to reduce your buildings heating and cooling costs.

Some argue that this type of roofing system is not the most aesthetically pleasing but then that is generally insignificant to a building owner. Alternatively, this type of roof is available in different colours like white grey or black and it can be manufactured in wide rolls to minimize the number of seams.

Single-Ply roofing systems are ideal for retro-fits because it costs less than a complete re-roof and is less intrusive. The job just needs to be done professionally.

EPDM Roof Replacement & Recovery

EPDM Roof Recovery TorontoThe most distinct difference between EPDM (ethylene propylene diene monomer) and other roofing systems like it (TPO and PVC) is that it is installed with glue/adhesive. The edges are then mechanically fastened using nails and heat sealed seam tape is placed along the seams helps to ensure the roof is watertight so welding is not required.

This is just a part of the process of an EPDM roof replacement or recovery. Before any of that is even considered ensure that a re-roof or replacement is really required. Just because you are having an extreme issue in one area does not mean that the entire roof must be replaced. Have your roof thoroughly inspected by a professional. A partial recovery on only the damaged sections of the flat roof or seam repair is much more cost effective than the replacement of your entire roof.

This type of roof is available in different colours like white grey or black and it can be manufactured in wide rolls to minimize the number of seams. The colour options are not for aesthetics but reflectivity. A white reflective roof easily exceeds the energy star reflectivity rating performance requirements.
