Roof Systems
in Cambridge, MA
A membrane name on a roof plan does not tell us whether seams, insulation, or edge transitions remain serviceable. We verify the installed assembly before proposing a repair or replacement. Cambridge's building mix includes life-science and technology facilities alongside offices, housing, institutional, retail, and industrial uses; the occupancy below and roof details above both affect system selection. We install and repair single-ply, built-up, modified-bitumen, metal, foam, and coating systems. A TPO assembly is reviewed at its welded seams, penetrations, and perimeter details, while a PVC system needs a compatible repair method based on its membrane and condition.

What Owners Should Know
What should be confirmed before choosing a system?
We check deck, attachment, existing layers, drainage, equipment clearances, and the condition of the current membrane. An EPDM roof has different seam and flashing details than a modified-bitumen assembly. A roof plan, product label, and field test can help identify what is present. We do not select a new system from a building's use or a nearby property. The report lists confirmed details, unknown layers, and areas that need an opening before quantities are final.
How do repair choices differ by assembly?
Some defects can be patched; others require a broader tie-in or a full section review. We match repair materials to the existing roof and examine how water moves across seams and flashings. Built-up roofing is inspected for surfacing, embedded reinforcement, and exposed transitions. A standing-seam roof calls for attention to panel joints, fasteners, and movement. Metal retrofit requires review of the existing deck and attachment. The estimate distinguishes a confirmed repair from a recover or replacement scope, with testing and access needs identified.
Where do coatings and foam fit?
A coating needs a compatible surface that can be cleaned and prepared, and its details must be reinforced as specified. Silicone coatings are considered after the substrate and drainage are checked. Spray foam is reviewed for adhesion, surface condition, protection, and drainage. A coating or foam application does not substitute for resolving wet insulation or a failed deck. We document the test result, repair boundary, and condition needed before installation.
How is system work scheduled?
Work proceeds by roof section, with access, occupied rooms, equipment, and weather limits agreed in advance. Cambridge reports more winter thaw-freeze swings and heavier precipitation; the city's planning context helps focus drainage review, while current site conditions govern preparation and closure. We secure opened areas before leaving and record the materials used. A KEE membrane or a fluid-applied coating is installed only after its assembly and preparation are confirmed. The closeout identifies completed details and any section left for testing.
Commercial Roofing Questions
Can a roof plan alone identify the installed membrane?
It is useful evidence, but field labels and accessible details should be checked. If records and roof conditions disagree, we document the difference before selecting materials.
Can different systems be compared on price alone?
The roof condition, drainage, attachment, substrate, access, and planned service life affect scope. We compare what each option requires and state any test that remains open.
When is a coating appropriate?
Only after the existing surface, moisture, preparation, and details support that system. A coating does not correct concealed damage by itself.
What belongs in the system closeout?
Keep the membrane identified, repair boundaries, preparation notes, material information, photographs, and any warranty or access records supplied for the project.
Identify the roof assembly first
Send the property address, roof plan or system records, reported condition, and access contact. We will identify the assembly and document the repair or replacement options.
