GRP / Fiberglass / Rubber (EDPM) Roofing
GRP roofing has many benefits and one of them is the strength to weight ratio it has. GRP stands for Glass Reinforced Plastic. It is made from resin which has glass strands and is also a liquid that solidifies over a short period of time after a catalyst is applied to it. The resin reinforces the roofing material. GRP’s properties are numerous and make it easy to be molded around or over uneven roof shapes and odd structures. It’s resistance to corrosion also makes it the best roofing material for properties located near chemical industries or factories.
GRP Roofing Lifespan
A GRP roofing also known as fiberglass roof is a long-lasting roofing option that can protect your housetop for more than thirty years without any visible damage or corrosion. The main characteristic that increases its life span is the fact that it has no seams. It is highly water resistant, a quality that makes it suitable to be applied in a wide range of marine purposes. Blistering, cracking, mold and mildew do not occur in this type of roofing material, and it is also impervious to sunshine.
Rubber (EPDM) Roofing
EPDM roofing can last for as long as twenty years which makes it a very interesting and suitable roofing material choice. It has a rubber-like aspect which is flexible and breathable but impervious, that is, heat and vapor can be discharged but can’t penetrate into the roof. The ability of rubber roofing to resist water and salt water is incredible which makes it the safest option for houses built in coastal areas. This type of roofing material is used on roofs with irregular structures and also on gutters and pipes with no adverse effect or problem. The flexibility of EPDM roofing makes it unable to break easily or get damaged by cracks. It also allows for expansion and contraction as it can stretch in length and return to its original size. EPDM stands for Ethylene Propylene Diene Monomer.
Rubber (EPDM) Roofing Lifespan
The lifespan of EPDM roofing is incredible and also similar to GRP roofing. It is seamless and also water resistant which makes it suitable to be used in sealed environments, ponds and valves. The elasticity of EPDM roofing prevents cracks and tears or splits in the roof even through thermal movement (contraction or expansion). Like GRP roofing, rubber roofing is also unaffected by sun.
GRP and EPDM installation Process
GRP installation can be a very daunting task due to the addition of several resins and catalysts but can be carried out by roofing specialists who understand the techniques of installing it. This is not a simple process and therefore requires professional skilled contractors. Another important detail to take note: GRP can only be installed during the dry season. While GRP has to be prepared on site, EPDM is manufactured in premade rolls and can be installed by skilled and efficient professionals. Make sure to always hire an experienced company as improper installation of EPDM can have costly and damaging effects on your roof.
