Bellevue Area Commercial Roofing

Guardian Roofing has found that commercial building owners and managers want the same quality installations, repairs and maintenance services we offer our homeowners.

At Guardian Roofing, we understand that business owners, general contractors, investors, design companies, and other contractors and organizations have unique needs when compared to homeowners. However, we also know that even if you are a company, you still deserve to be treated with the same respect and care as any individual. No matter what your special needs might be, our roofing contractors are determined to find solutions to make it happen. When others say “no,” we say “absolutely.” 

Commercial Roofing Service Offerings

New Construction

Whether you are building a small office building or a large multi-building plaza, we can provide customized solutions for your new construction project. No matter what your needs are, we can make sure that we deliver on time and on budget. Our touchstones are always professional customer service and excellent workmanship, every step of the way. 


Re-roofing could mean an entire commercial roof needs to be replaced, or it could just be a section of it. Guardian’s commercial roofing experts have the knowledge and experience to handle any roof re-roofing project you might have. 

First, we will try to determine the scope of the project. This involves checking to see how much damage there is, and what needs to be replaced. Do you need a new decking as well as a roof surface? Depending on the nature and location of the damage, we will provide an accurate estimate that accounts for labor, materials, permits, and everything else involved in replacing a roof. 

The cost of re-roofing depends on:

  1. if the decking must be replaced,
  2. which roofing materials are chosen,
  3. the square footage of the area being re-roofed, and
  4. ease or difficulty in accessing the section of roof that must be replaced (are hydraulic lifts necessary? scaffolding?)

Repair and Maintenance Programs

Ask us about our Guardian Commercial Repair and Maintenance programs.

Almost every roof will end up having damage at some point. The roof is the first line of defense against mother nature, and it bears the brunt of everything she throws at the building. Not only will heat and rain affect your roof, but it could also be impacted by other objects, such as falling tree branches. If someone goes on the roof and is not careful about where they walk, then the tiles could crack. Weather and wind could pull up an entire roof, or hail could damage the shingles. 

Leaks can happen as well for a variety of reasons. For one, the roof may not have been installed correctly. Or, the roof could just wear down in certain spots until water is finally able to sneak through a gap. Whatever the reason, a leaky roof can be a big problem for a commercial building. It might mean having to shut down your operations, or if you have customers who come in to your work, you may have to shut down until things are safe again. 

Bellevue Guardian commercial roofing experts make sure that they do their repairs as efficiently as possible while also maintaining their lofty workmanship standards. However, by signing up for regular maintenance visits, you may never need a repair. A technician will examine every inch of your roof and make any small repairs as needed, keeping your roof strong throughout its life. 

Emergency Service

When your Bellevue commercial building’s roof is damaged, or you notice that it’s leaking, then you don’t want to delay getting it repaired. Every second that it is left unaddressed means there could be more water damage, or your operations are interrupted. Guardian offers emergency service 24 hours a day, 7 days a week. We can have experts to your building as soon as possible to make sure you have timely repairs. If we don’t have the equipment on hand or if it is unsafe at the time, we will install a temporary solution until we are able to complete the repairs. 

No Dollar Limit Warranties Available with Some Products

Guardian is confident in the work we do. That’s why we have several warranty options. You will be protected in case of any mishaps or errors during the work. 

Single Ply TPO and PVC

One of the best things you can do to protect your commercial roof is have it coated with thermoplastic polyolefin (TPO). It reflects the sun, which not only prevents roofing materials from wearing down, but it is also an energy-efficient heat repeller. 

Torch down – Smooth and Granulated

Torch down products are applied using extremely high heat from a torch. It is sometimes used on houses but is most often used for commercial roofing. 

Metal Roofing

Commercial and residential clients in Bellevue are turning more and more to metal roofing. They are extremely strong and can last up to 50 years. They can be repainted as many times as you like, and there is little maintenance needed. A metal roof holds up extremely well to the elements, and with a raised seam product, it is virtually waterproof. Another benefit is that if your old roof has failed, a metal roof can be installed right over the existing one, saving you on disposal costs. 

Asphalt Shingles

Asphalt shingles are probably the most common shingles used for commercial buildings. They are manufactured with several layers of a granular aggregate. Usually, these shingles can last up to 30 years, but some individual shingles must be replaced if they are damaged or fall off. 

Roof Coatings

Roof coatings help protect your roof and also the building. They reflect heat and provide a waterproof seal on the roof. With less heat able to enter the building, your HVAC system won’t have to work as hard and you can save on your energy bills. 

Wood shakes

Wood shakes are like shingles, but they are much larger and more solid. They are hand-split and sawn to custom sizes, depending on what the client is looking for. They are often used to give off a rustic or traditional look to a roof.
