Commercial Roofing Service Offerings


Avondale Commercial Roofing

Does your commercial roof need to be replaced? Does a portion of it need to be re-roofed? Guardian’s commercial roofing division teams are experienced in roof replacements and re-roofing projects.

Consult a Guardian professional to help you determine the scope of your project. If your roof has sustained extensive damage – either through a major weather event, because of long-term neglect, or through other factors – it is possible that the decking must be replaced in addition to the roof itself.

This of course involves more supplies, labor, time, planning, permits, and cost.  A Guardian roofing expert will assess your roof to determine if the decking needs to be replaced as well as the roof. Call us today at 877-926-9966 or request your appointment online »

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 & Maintenance Programs

Repair and Maintenance Programs

Ask us about our Guardian Commercial Repair and Maintenance programs.

Leaks and damage happen to all commercial roofs at some point. As large, exposed structural features, roofs are vulnerable to all manner of forces. They can get struck by flying or falling objects such as branches and golf balls. Barrel tiles or slate tiles may crack or break when struck or walked on incorrectly. Weather events can cause whole sections of roofs to be ripped off. Hail on asphalt shingle roofs decimates the aggregate and renders it ineffective.

Leaks are another type of roof damage that occurs often. Sometimes a portion of the roof has been installed improperly, and a leak develops as a result. Sometimes a part of the roof is more vulnerable than the roof in adjacent areas, and over time the weaker area begins to leak.

A leaking roof or a damaged roof impacts the spaces, systems, and people underneath it. For some commercial applications, ceilings and walls that are breached by water spell disaster to equipment, processes, and operations.

Western Washington Guardian commercial roofing specialists are experts in speedy, thorough roof repair. Our maintenance program includes periodic visits by a roofing professional to examine your roof and catch vulnerable areas before they develop into leaks or damage. Ask us about our commercial repair and maintenance programs.

Emergency Service

When the roof on your Seattle, Washington commercial building sustains sudden damage or develops a quick leak, you need a repair crew fast. Guardian’s commercial roofing professionals deliver emergency repair services day and night. Our expert roofers identify leaks and sources of damage quickly, addressing and resolving them while striving to impact your business operations as minimally as possible.

In cases where specialized materials are needed, the emergency service will affect a temporary solution, and a Guardian team will return to complete the repair with the necessary supplies.

No Dollar Limit Warranties Available with Some Products

Guardian offers a range of warranties on our commercial roofing products. Speak with one of our knowledgeable representatives to find out which product is best for you, and which warranty suits your needs the most.

Single Ply TPO and PVC

TPO, or thermoplastic polyolefin, is a commercial roofing material that provides robust performance in the face of the strong year-round sun. For this reason, it is a popular choice in many southern U.S. states. TPO’s reflective properties make it an energy-efficient option that also appeals to Eastern Washington commercial property owners.

Torch down – Smooth and Granulated

This product derives its name from the way it is most often applied—with a source of high heat like a torch. Sometimes used for residential roofs, it is most often a commercial roofing choice.

Metal Roofing

More and more of our Seattle commercial clients are cladding their roofs in metal because of the many benefits of this material. Metal roofs last 30-50 years, can be painted and repainted, come in many colors, and do not require a lot of maintenance. Metal roofs, properly constructed and installed, stand up well to most extreme weather events. They are sustainable (most contain 30-60% recycled material and are fully recyclable) and can be installed over existing roofs. Reflective solar coatings reduce heat buildup, which results in significant energy savings.

Asphalt Shingles

Asphalt shingles are a popular, cost-effective commercial roofing material choice. They are composed of layers of a granular aggregate bound with a limestone filler. These shingles are typically rated for 15, 20, or 30 years. Over time, exposure to weather breaks down the aggregate, and it wears off. When enough of the pebbly layers have worn off, the shingles need to be replaced.

Roof Coatings

Guardian carries a variety of roof coating products that can be applied to commercial roofing materials to extend their lifespan. Some coatings also have reflective properties that greatly diminish the amount of heat entering a building through the roof. Ask a Guardian representative which coating is the best for your commercial roof.

Wood shakes

Wood shingles and wood shakes are both common roofing materials. Their differences lie in how they are cut and, in their thicknesses, and profiles.

Shingles are sawn smooth, cut tapered, and usually come in several lengths and thicknesses.

Shakes are thicker than shingles. They may be hand-split and re-sawn or taper-sawn. Their faces may be rugged, lending to a rustic-looking roof, or semi-textured. Usually, several thicknesses are available in different types of shakes.
