The Lone Star State has been known to have some intense weather from time to time. When you’ve got a business to run, you need a roof that you can rely on to hold up under every meteorological circumstance. But how do you determine which commercial building roof is right for your business? With so many options on the market, determining which type is best suited for your needs may not be so easy. As one of the most trusted commercial roofing companies in Northern Texas, we’ve compiled a comprehensive guide to help you make that decision.

To get a feel for which commercial roof types might be right for your business, read on, then give us a call for a free roofing estimate. Parish Roofing is dedicated to providing clients with clear communication, realistic estimates, and a job well done.

Things to consider when choosing a roofing system

There are many types of commercial roofing systems, but not all will fit your needs. When choosing a roof, you need to consider the type of facility you’re working with. To pick the best system for you, consider the shape of commercial roofs. Most roofs will fall under the low-slope category, but some may be steep slopes– these are usually meant for residential homes rather than businesses and are made of metal, shingles, slate, or tiles. Other factors to take into account include your budget, the building size, weather conditions in your area, building usage, climate, and material lifespans.

Your Budget

When planning your budget for a commercial roof, location, energy efficiency, existing roof conditions (if there is any), labor costs, building height, roof pitch and size, and selected materials will affect your pricing. If you’re looking to save as much cash as you can, we wouldn’t recommend mod-bit roofs or built-up roofs, as their multiple–layer design can be costly to install and repair over time. Metal roofs are going to be the most cost-effective choice, and they come in a wide selection of aesthetics.

Your Building’s Size

There are two main roof shapes: low-slope and steep-slope roofs. Low-slope types of commercial roofing systems are commonly associated with warehouses, box stores, and shopping centers and are made of EPDM, PVC, or TPO. Generally speaking, most types of commercial roofing will be flat or have only a slight slope as they are meant to cover large buildings.  The larger your building is, the more material it will take as well, increasing your project's cost.

Your area’s weather conditions

In considering all the types of commercial roofs available to you, weather conditions in your area are important to take into account. If you live somewhere where high winds are common, shingles may not be the best choice as they provide the least protection from wind and will need replacing every 10 years. If sun exposure is a big concern, a metal roof could be the way to go as they’re highly reflective and, therefore, can keep your building cooler, offering an energy-efficient roofing solution.

Your new roof's lifespan

Replacing your roof a million times is obviously not ideal or sustainable for any business. Choosing a roofing material with a longer warranty or life span is crucial to avoiding this. Material Life spans will depend on installation quality, climate conditions, maintenance practices, foot traffic, and other environmental conditions. If installed correctly, metal roofs can last a commercial business between 40 to 70 years on average. Built-up roofs, also called hot tar roofs, have one of the longest life spans at 20 to 30 years. Mod-bit roofs, when maintained properly, can last 20 to 30 years.

What kind of roofing systems are available through Parish Roofing?

It goes without saying that each material will hold up a little differently over time. With so many options flooding the market, deciding which one to go with can be difficult. Allow us to simplify the process for you by providing the best options available. We offer four commercial building roof types: rolled roofing, Thermoplastic Olefin (TPO), flat-coated roofs, and standing seam metal.

Rolled roofing

Rolled roofing is available in multiple kinds, such as modified bitumen, ethylene propylene diene monomer (EPDM), rubber rolled roofing, and Thermoplastic Olefin (TPO). Before determining whether or not rolled roofing is a valid option for you, our team will look at the damage and the roof's overall condition. If the damages are extensive, the entire rolled roof will be replaced. This process involves tearing off the original roof, cleaning the surface, applying roofing cement, and then properly rolling out the new material.

TPO

TPO is a single-ply kind of extremely flexible and robust roof, making it one of the most common and preferred materials on the market. It’s made of a single-layer synthetic and reinforcing scrim, usually placed on flat roofs. There are three kinds of TPO installations: Polyisocyanurate (Polyiso), Expanded Polystyrene (EPS), and Extruded Polystyrene (XPS). We’ll carefully assess your roof’s condition before replacing or repairing it. For less severe issues, we’ll repair it by heat welding a new patch to the old roof. If it’s a bigger problem, you may be better off replacing it entirely.

Flat-coated roofs

There are multiple versions of flat-coated roofs, such as TPO, EPDM, fiberglass, PVC, GRP, mineral felt, torch-on felt, and mastic asphalt. Other roof coatings include acrylic, silicone, polyurethane, and Fluid-applied asphaltic rubber membrane. If your flat-coated roof needs servicing, we can repair or completely replace it. We’ll ensure our work is top-quality so that your coated roof lasts long and can endure even the toughest weather conditions.

Standing seam metal

One of the two main types of metal roof systems, standing seam metal, is designed with interlocking seams that connect panels and are made from steel or aluminum. Popular for their energy and cost efficiency, standing seam metal roofs are watertight and excel at protecting commercial buildings from the elements. Our team will work to assist you with roof installations, replacements, and repairs.

As a small business, we understand the importance of making smart financial decisions. That’s why we offer affordable financing options for all commercial roofing types. Parish Roofing provides free estimates, a personalized monthly payment plan, and no prepayment penalties. When you work with us, no home equity is required, and you’ll receive funding within 1-3 days.

Additional Commercial Roof Types

PVC

Polyvinyl Chloride (PVC) roofs are made of two layers of PVC and a polyester reinforcement scrim. The first layer contains an additive that makes the membrane resistant to UV rays, while the bottom contains plasticizers that make the material flexible for easy installation. Like standing seam roofs, PVC is watertight thanks to its ability to be welded to other sheets. It also can be made to look like a seamed roof through a process involving welding a premanufactured rib to the roof’s surface. PVC roofs are extremely durable, recyclable/reusable, have a long lifespan, and are fire resistant.

EPDM

Ethylene propylene diene monomer (EPDM) roofs are made from a chemical compound known for its elastic qualities and durability. Like PVC, EPDM roofs are resistant to UV light. This material is popular within the commercial roofing community thanks to its low cost and resilience. As a type of synthetic rubber made of natural gas and oik, EPDM roofs are used mainly in low-slope commercial buildings.

Mod Bit

Modified bitumen (Mod bit) roofs are made of both asphalt and a chemical polymer that makes it the ideal material for high temp locations. It’s also very flexible and can be applied in layers, either through torch-applied, self-adhesive sheets, hot-mopped asphalt, or cold-applied adhesives. The layers overlapping seams are then welded together, making it resistant to the worst of the elements.

Built-Up

Built-up roofs (or BURs) are a tried-and-true method used by commercial roofers for decades. They are constructed by layering hot or cold asphalt between sheets or felts of materials to secure them together. Made of 3-5 layers, literally built up on top of one another, BURs are ideal for climate protection in both low and high temperatures.

What commercial roof shapes are available?

Due to their sheer size, commercial buildings have less slope than residential structures. Their slopes are rarely visible from the ground, demonstrating minimal lift. Identifying the slope of your business's structure is important in determining what materials are best suited for your needs. Generally speaking, your roof will fall into one of two categories: a flat or sloped roof.

Flat roof commercial roof types come in five varieties that can then be categorized further: BURs, metal (aluminum, steel, galvalume), Mod Bits, single-ply membranes (TPO, PVC, EPDM), and spray polyurethane foam-based roofs. While all are good options, keep in mind that the best type of flat roof system will depend on your building’s specifics. Sloped roofs are either low or steep. The term “steep” applies to roofs with a slope of 3:12 or higher. They can be made of various materials, such as asphalt shingles, metal panels, clay tiles, fiberglass shingles, concrete tile, slate, metal, and wood shakes/shingles.

Installing Your Commercial Roof

Installing your commercial roof isn’t something you want to leave any average Joe in charge of. It’s a complicated process that involves a certain kind of planning and prepping that only a professional can do– professionals like the team at Parish Roofing. We’ll begin by evaluating your existing roof, work with you to choose a material that suits your budget and building’s needs, design a comprehensive plan, and get to work on making it a reality.

If need be, our team will rip out the existing roof and confirm that what lies beneath is safe to start building on again. At each step, we’ll perform quality tests to ensure you’re getting our very best work and stick to the design plans and local building codes. If we run into a complication, we’ll work with you to pivot without losing valuable time.  As an improperly installed commercial roofing system could spell big trouble for your business, trust installation to Parish Roofing.
