What’s the best commercial roofing material?
Ohio has some rough winters which can abuse a commercial roof. Repairs are common when spring rains come because of the damage a roof takes from the ice and snow. A professional contractor that is experienced in commercial roof repair will typically be armed and ready in the spring for the onslaught of call they anticipate.
They are well versed in the types of commercial roofing and commercial roofing materials, knowing the best commercial roof repair method for every type of flat roofing material. Should a commercial roof need replacing instead of repairing, they can advise the best commercial roofing material for that particular building.
Regardless of what type of commercial roofing material you choose, if the commercial roof installation isn’t done correctly, there will always be the possibility of problems. Those problems can be buckling, cracking, and worst of all, leaking, which leads to commercial roof repair jobs.
There are many types of roofing materials for commercial structure, and if you’re not sure which is the best, you should review each one. Choose one that is best for your property and for the climate where you’re located.
Consider the maintenance and commercial roof repair possibilities over the years, and the how long each roofing material lasts. You should consider the energy efficiency too as well as the colors of each roofing material. In a cold weather climate like Ohio, dark-colored roofing is the preferred choice because it retains heat from the sun. Things to consider about your roof:
- Is it visible from the street or other buildings?
- Does it have a lot of foot traffic?
- Is it exposed to acid, chemicals, or grease?
- Does it have a lot of exposure to the sun?
- Is it exposed to high winds?
- Is the temperature range extreme?
What is the best material for a low-pitch roof?
With these things mind, if your commercial structure has a flat roof or a low slope with under 4 inches within a 12 inch drop, the following roof materials are recommended:
Thermoplastic Polyolefin, (TPO), is a single-ply roofing membrane of plastic materials that offers many qualities. The seams are made extra durable by being heat welded and for areas where the sun gets extremely hot, TPO has great reflectivity that keeps the interior of a structure cool.
Polyvinyl Chloride, (PVC), was the reigning single-ply roofing material before TPO came along. It offer similar qualities and is an ideal alternative to the Built-up Roofing, aka tar and gravel. It is flexible and can be heat welded. It is considered a cool roof material and withstands more chemicals than TPO, making it ideal for restaurants with the kitchen venting on the roof.
Ethylene Propylene Diene Terpolymer, (EPDM), is a modified rubber material offering several great qualities for flat roofing. It is a supremely flexible material that can withstand hot/cold cycles for decades and flexes with a building as it settles. Chemically inert this roofing material can withstand most chemicals and is used to line leach pits or retention ponds. This is the strongest resisting roofing material again hailstones and punctures. Not recommended for roof with heavy foot traffic.
This single-ply roofing material is also referred to as Atactic Polypropylene, (APP). This asphalt product is less expensive than the plastic and rubber membranes and resistant to pooling water. It can be installed by torch-down or a peel and stick self-adhere. Definitely an economical choice for upfront cost but will need replacing sooner than other materials.
Commonly called tar and gravel, this built-up roofing style has been used for more than 100 years and the many layers to create the style makes it durable and hailstone resistant. The reinforced felt is adhered with a hot liquid asphalt, with pea gravel on top providing the UV protection.
Which is better EPDM or TPO?
EPDM can shrink easily, creating and leading to bigger problems on a flat or low sloped roof. For dimensional stability, TPO is the most recommended over EPDM. If commercial roof repair frequency is a concern, TPO may be the better option.
Are metal roofs good for low-pitch roofs?
Metal roofing is excellent for a low slope commercial structure roof, but it does need a minimum slope. For lapped and non-soldered seam metal roofing, 3 units is required vertically to 12 units horizontal, meaning a minimum of 25% slope.
Regardless which type of flat or low slope roofing material a commercial structure owner chooses, they want to get the most for their money. This isn’t a cheap endeavor, even with the material claiming to be the least expensive. So, with all things factored into the equation, how long should a commercial roof last? With the exception of built-up roofing, a professional and property installed commercial roofing that is maintained as recommended, can last up to 40 years or longer.
