Roof Systems for Gresham Buildings
The right commercial roof system depends on the deck, insulation, drainage, operating use, and condition of the layers already in place. A material name does not answer whether the roof can be repaired, recovered, or replaced. We inspect the field membrane, seams, flashing, edges, and penetrations before recommending a system or tie-in. Gresham's wet season makes drain paths and daily protection important parts of installation planning. The system also needs to fit the way the building operates.
Compare membrane families
Thermoplastic systems use welded seams, while EPDM uses different seam materials and repair methods. A TPO roof and PVC roof each require compatible accessories and details. EPDM has its own sheet, seam, and attachment considerations. The inspection confirms the installed product where records or visible material allow. A patch should not bridge different membranes without checking compatibility.
For multi-ply systems, modified bitumen uses layered sheets and detailed laps. A built-up roof may have several plies and surfacing that need to be identified before repair. Existing layers influence whether another system can be added or whether removal is needed.
Review metal and fluid-applied options
Metal roofs need attention at seams, fasteners, penetrations, and panel movement. A metal retrofit can be evaluated when the existing roof and framing support the proposed assembly. Coatings require a compatible surface, preparation, and detail plan. A silicone system or an acrylic coating cannot correct trapped moisture or failed attachment beneath it.
Spray foam is another roof assembly with its own substrate, thickness, drainage, and protective coating requirements. We inspect the existing roof and project details before evaluating a foam system or coating renewal.

We will inspect the current system, document visible conditions, and explain which repair or renewal options fit the building.
Choose by condition, not a label
We check roof layers, wet areas, attachment, drainage, parapets, equipment curbs, and access. If an owner is considering a recover, the assembly needs to support added height and remain suitable beneath it. If removal is needed, the scope can include new insulation and phased work around operations. The inspection also identifies tests that could change the recommendation.
A property in Southshore Corporate Park or a Gresham commercial district still needs a building-specific survey. The same system can behave differently when details, drainage, or service traffic differ.
Plan the installation sequence
A replacement or recover can affect occupants, deliveries, rooftop equipment, and the routes crews use. We divide work into zones, plan a dry-in step, and check that drains remain available. Material access and weather can change the order. The project scope records which details will be rebuilt, what existing layers remain, and what the owner needs to approve before removal begins.
Roof Systems FAQs
-
Can you install a new membrane over an old one?
Only if moisture, attachment, surface condition, drainage, and added height allow it. We inspect the existing layers before recommending a recover.
-
How do you identify the roof system already installed?
We review owner records, product labels, visible seams, and assembly details. If the material remains uncertain, we identify what further inspection would confirm it.
-
Can a coating fix a leak by itself?
A coating can be considered for a compatible, prepared surface. We first check the leak path, substrate, wet insulation, and flashing details.
-
Which system is right for my building?
The deck, roof layers, drainage, operating use, and project constraints shape the decision. We inspect those conditions and explain viable options.
