Identify the Sarnafil assembly and failure point
A split at a curb flashing can be harder to read than a puncture in the field. On a Sika Sarnafil roof, we identify the PVC membrane, seam condition, attachment, and flashing detail before marking the repair limit. The Sarnafil family includes thermoplastic PVC sheets with hot-air-welded seams. Some variants are adhered, while others are designed for mechanical attachment. The installed assembly decides how a repair ties in.
We begin with the roof plan, labels, and visible transitions. Each finding goes on a photo record tied to its roof location. That sequence keeps a seam concern separate from a wet insulation question or an unrelated interior stain. If records are incomplete, an assembly inspection identifies what can be confirmed and what needs a test opening before permanent work is specified.
Sarnafil membrane details
Sarnafil G 410 is a fiberglass-reinforced PVC thermoplastic membrane with hot-air-welded seams. S 327 includes mechanically attached options and felt-backed choices for certain assemblies. These product differences affect field seams, perimeter terminations, and transitions. We identify the installed membrane, surface, attachment, and insulation package from records and field conditions before selecting a repair.
A weld inspection starts with cleanliness and seam width, then moves to corners, laps, and flashing. We look for fishmouths, open edges, wrinkles, punctures, and repairs that interrupt drainage. A compatible patch has to match the membrane and its detail. Sealant at a visible edge may mask the opening without repairing the welded joint. We document whether the defect sits in the field, at a curb, or where the roof turns up a wall.
At Olde Town Arvada, exterior changes can intersect with district review requirements. That planning fact does not establish which PVC system is installed on a nearby property. It does make early coordination useful when a roof scope changes visible edge metal, rooftop equipment, or covered exterior details. We identify that work separately from concealed membrane repairs.
Attachment and transitions
Attachment determines how a sheet responds across the roof and where its fasteners or adhesive need inspection. Sika's Sarnafil family includes adhered and mechanically attached system options. A mechanically attached detail concentrates attachment at designated lines, while an adhered assembly relies on a bond to an approved substrate. We check what is actually installed, including deck, insulation, cover board, and perimeter securement.
The most exposed transitions often deserve a slow walk. We inspect parapets, curbs, pitch pockets, drains, skylights, and edge metal. If a membrane terminates at an old repair or another roof type, we record both sides and the way they join. A separate penetration-flashing inspection can resolve a leak near rooftop equipment without confusing it with a field seam. Where the perimeter is involved, edge metal review documents the attachment and water path.
Arvada adopted updated 2024 building codes on a 2026 city implementation schedule, with revised wind, seismic, and snow provisions. Replacement and recover work should be checked against the project's applicable code path. We review attachment and edge details as part of that scope, rather than carrying an old fastener pattern forward without verification. The report notes design documents that would help the next decision.
Storm walk and evidence
Arvada experienced hail and wind in the May 2017 metro Denver supercell. On a Sika Sarnafil roof, we inspect perimeter details, seams, penetrations, drains, and equipment supports, then record impact marks, cuts, loosened sheet edges, and interior reports separately. The property's dated report and roof records help set the inspection area.
For a recent event, give us its date and the rooms where water appeared. We map each observation on the roof plan and pair the image with a description. If water is active, temporary protection comes first. The permanent recommendation follows after we connect the interior condition with the roof detail, identify access limits, and decide whether moisture testing or a small opening is needed. We document each property near Arvada Marketplace by its own assembly, roof details, and observed conditions.
Denver International Airport's 1991-2020 normal seasonal snowfall is 47 inches. For snow-related concerns, we inspect drain paths, overflow provisions, low spots, and visible movement and review the building's design information. A separate snow or ice condition review can document what the roof itself shows.

Repair path and scope
A localized puncture or weld defect can support a focused repair when surrounding material remains sound. Repeated seam trouble, wet insulation, widespread loss of attachment, or deteriorated flashing can change the project boundary. We describe the observed extent and distinguish it from areas that still need testing. A repair proposal states the preparation, compatible membrane, detail work, and closeout photographs that the task requires.
When the assembly has failures in several zones, compare repair with replacement planning. A recover is considered only after checking existing layers, moisture, drainage, deck capacity, and code requirements. An owner's schedule can also affect phasing. We plan access, material staging, daily dry-in, and protection for occupied space below. For a project with different membrane sections, compare Carlisle SynTec systems and GAF TPO by assembly and repair detail, not by brand label.
A report closes with completed work, observed conditions outside scope, and the next decision. We retain the photo record so a later maintenance visit can compare the same seams and transitions. Send the property address, storm date, access notes, and existing system records. The first roof walk can then focus on the Sika Sarnafil sections that need attention.

Questions about Sika Sarnafil Roofing
How do you confirm which Sarnafil membrane is installed?+
We compare records and product marks with the field sheet, seam, flashing, and attachment details. The report names confirmed items and calls out sections where access or hidden layers prevent a firm identification.
Can a welded seam be repaired with surface sealant?+
A sealant bead may not restore a failed weld. We inspect the seam, clean and prepare compatible material, and specify a welded repair when the defect and conditions require it.
Does a Sarnafil label mean the system is mechanically attached?+
No. The product family includes different system configurations. We inspect fasteners, bond, substrate, and edge conditions before documenting attachment.
What does a hail report change about the inspection?+
The storm date helps organize photos and reported interior water. We then inspect actual roof conditions. A regional weather event does not establish damage at a specific property.
When should an Arvada owner consider a broader reroof review?+
Several affected zones, repeated leaks, wet insulation, or perimeter movement can warrant a wider condition review. The mapped findings show whether repair limits remain local or extend further.
