If you own a commercial building in Idaho, Montana, or Washington, you may eventually have a problem with roof leaks or other damage. At this point, you face three options — live with the damage, repair it, or replace your roof. When the damage warrants replacing your roof, it could put a large dent in your bank account.
Roof repair may seem like throwing good money away if the problem could occur again. However, there’s another option to consider. North Star Roofing restoration prevents leaks and damage without the cost and inconvenience of paying for a complete roof replacement.
Learn more about this opportunity to restore the functionality and beauty of your commercial roof. Let’s discuss the most typical commercial roofing systems and the methods available for commercial roof restoration. Then, you can decide whether roof repair, roof replacement or roof restoration would work best for you.
Six Most Common Types of Commercial Roofs
Start by understanding which roof your building has. The six most common types of commercial roofs include:
- Built-Up Roofing (BUR) Membrane
- Metal Roofing
- Modified Bitumen Roofing
- Thermoset (EPDM) Roof Membrane
- Thermoplastic (PVC & TPO) Roof Membrane
- Garden Roofing
Built-Up Roofing (BUR) Membrane
Built-up Roofing Membranes are known as “tar and gravel” roofs. They consist of layers of bitumen and roofing fabric. A well-built BUR roof lasts up to 30 years and protects your property from UV rays, water intrusion and weather events. They are easy and affordable to built and maintain. However, it can be difficult to locate the origin of a leak without significant time and effort. Also, these roofs are less flexible than other options, making them vulnerable to structural damage.
Roof repair is problematic due to the difficulty in sourcing the leak.
Metal roofing consists of pieces, tiles or sheets of metal, and these roofs have a good reputation for water resistance and long-lasting durability. A variety of metals are used, such as corrugated steel, zinc, copper, aluminum and steel alloys. Some owners cover the metal with protective coatings to prevent rusting and UV damage.
This green roofing alternative uses recyclable material, lasts 30-75 years and is energy-efficient. However, they cost between $10 to $18 per square foot to install and severe hail can ruin a metal roof. Metal roof repair can cost a lot of money and you need a professional to get it done.
Modified Bitumen Roofing
Modified bitumen roofing (MBR) provides an alternative to BURs. Developed in the 1960s, it’s a popular choice for commercial buildings. Roofers use long 3′ x 36′ sheets of asphalt-based material, which is protected by a mineral coating. It’s simpler to install and more flexible than BUR in extreme temperatures. However, installing them requires an open flame in some cases, and if the overlapping sheets fail to adhere properly, you’re likely to get a leak. Like BUR, it’s not considered an aesthetically pleasing roof option.
MBR roofs require attention to detail and perseverance to find and fix leaks. If you don’t remove all the moisture that soaked through to the asphalt, you may patch over the moist areas, inviting mold and other problems to develop.
Thermoset (EPDM) Roof Membrane
EPDM roof membranes are made of the same materials used to line fish ponds. Constructed of heavy-duty rubber, these membranes adhere to the roof via glue or metal fasteners. Though durable, easy to repair, foot traffic and fallen tree limbs can puncture the material fairly easily.
The seams between membrane sheets are common areas for leaks, even though they are sealed. Though some sources say repairing our roof can be inexpensive and done by building owners, extensive repairs are best done by a professional.
Thermoplastic (PVC & TPO) Roof Membrane
Thermoplastic roofing membranes are made of PVC and TPO material and are inexpensive to install, heat-resistant, and tolerant of hail, wind, and rain. However, there’s a lot of quality variation in the market. Also, seams pose an issue on these membranes when it comes to leaks and water incursion. As laminated materials, PVC and TPO roof membranes crack more easily than other roof types. Roof repair is similar to other membrane roofs discussed.
Garden “Green” Roofing System
A garden or green roofing system provides a beautiful, sustainable option for commercial buildings. However, vegetation can cause access issues if you need to repair or replace the roof. Typically, you have to remove the vegetation to repair the underlying lining.
Roof Restoration Methods
North Star Roofing offers another option to repair your roof. We can restore metal, layered and rolled roofing systems, through one of several processes. Keep reading to learning more.
Spray Foam Room Restoration
North Star Roofing applies the Conklin® Spray-In-Place Polyurethane Foam Roofing System to protect your metal roofing and stop leaks.
First, we remove debris from the roof and prime the roof with Conklin Base Kote, which provides an ideal surface for the restoration layer. Then, we apply the Conklin Spray Foam Top Kote Layer, a 1″ thick, energy-efficient spray that makes your roof look like new. It also reflects 85% of sunlight.
Metal Roof Restoration
North Star Roofing uses Conklin® Metal Roof Restoration Systems to restore your metal roof. First, we apply a rust-resistant solution, before priming the roof to provide a proper bonding with the sealant. Before applying the sealant, we caulk the roof fasteners and reinforce the seams to help prevent future leaks.
Commercial Membrane Roof Restorations
North Star Roofing also restores your membrane roof. Using Conklin® Membrane Roof Restoration Systems, we provide a long-term solution to roof leaks and damage. During the restoration, we clean off the membrane roof and treat the surface with detergent to remove accumulated dirt embedded in the roof using WAC II Conklin Roof Cleaner. Next, we prime the surface to make it easy for the restoration material to bond to the roof. We then reinforce all seams and caulk any fasteners to avoid leaks with the Conklin Spunflex Fabric joint material, which weatherproof these areas. Finally, we seal the entire roof using Conklin Rapid Roof III or another top-quality Conklin restoration product.
