Holcim Elevate Roofing Systems in Nampa, ID

A roof file may hold a certificate under the earlier company name, a bid under a contractor's name, and a plan that describes the membrane only by thickness and color. We read all three against the roof. The surface, the seam type, the fastening pattern and the flashing details usually confirm the family, and a core cut shows the layers when the evidence is thin.

Where a document and the roof disagree, the report states both. A certificate may describe a membrane that a later overlay has covered, or a repair section may have used a different material than the rest of the field. The report sorts these into confirmed and unconfirmed items, so the owner knows which parts of the roof the paperwork actually describes.

EPDM is a rubber sheet whose laps are bonded with tape or adhesive, and it is made in wide sheets that reduce the number of field seams. TPO is welded with hot air. Both are laid over insulation and attached by fasteners, adhesive or ballast. The inspection checks the seam condition, the fastener plates, the flashing terminations and the drainage path.

Wear on an EPDM roof tends to show at the laps and at flashings that have shrunk away from a wall. Wear on a TPO roof shows at welds and at places where foot traffic has abraded the surface. Each pattern leads to a different repair, and the report ties each finding to the section number, the date and a photograph.

Flashing at the base of walls and curbs gets its own pass. Pre-molded corners, pipe boots and termination bars are examined for cracking, stretching and open ends, and a failed accessory is replaced with a detail made for the membrane family instead of being covered with sealant. The roof walk ends at the drains, where strainers and sump flashings are checked.

Design requirements in Nampa vary by corridor, and the Highway 16 specific area plan is a case where a roof-mounted mechanical unit cannot sit on any structure within 500 feet of the road. For an owner on the State Highway 16 corridor who is planning a membrane replacement, the equipment plan is part of the roofing decision: units that cannot return to the roof need a ground-level home, and the openings they leave behind need to be closed with membrane details.

The work is coordinated with mechanical trades. Curbs that stay are reflashed, curbs that go are capped and covered, and the roof plan is revised to show the result. The curb and support work is entered in the same closeout file as the membrane.

The plan area runs from Ustick Road on its northern side to McDermott on the east, so a building near either road should have its position checked against the plan boundary before design begins. A building just outside the line is treated under the ordinary rules, and the file records which side of the line the property sits on, along with the date the check was made.

Wind is the load that matters most at a single-ply perimeter, and the city's criteria use 115 mph ultimate with no special wind region or wind-borne-debris zone. On a single-ply roof, the perimeter is where wind loads concentrate, so edge details get close attention: the metal flange, the cleat, the fasteners, and the termination bar at walls. Loose edge metal allows wind to lift the membrane beneath it.

During a walk, edge pieces are checked for movement, sealant is checked for cracks, and fasteners are checked for backing out. A repair that resets the edge uses the fastening method called for in the membrane's own detail, and the closeout photographs show the finished termination. The same check follows any wind event, even when no leak has been reported.

Gutters and downspouts at the edge are part of the same check. A gutter pulled away from the fascia, or a downspout that discharges against the wall, leaves water where the membrane termination can see it. Loose pieces are reset, and the discharge point is noted on the roof plan.

Beneath the membrane, insulation boards control heat flow and shape the drainage when they are tapered. If the boards stay dry, the roof can often be repaired or recovered. If they hold water, the membrane above is only a cover over a deteriorating layer. Meter readings, an infrared map and core cuts together show which condition applies.

The findings are written for the owner who has to choose. A dry result supports repair, coating or recover options. A wet result leads to a mapped removal area and a scope that replaces only what is saturated, or a full replacement where the wet area is widespread. The report lists the evidence with the choice.

Warranty terms come from the document issued for the specific roof, and we read them before any alteration that could matter. Visit logs, photographs and work orders are kept in the file so the maintenance a warranty asks for can be shown. Owners considering replacement can compare the existing assembly with Carlisle SynTec or Sika Sarnafil systems with the same inspection record in hand.

Winter conditions set the review calendar. Winter conditions set the review calendar, so a follow-up date is set before the wet season and another after the thaw, with over 75% of the year's precipitation arriving between November and May.

My roof paperwork says Firestone. Is that the same as Holcim Elevate?

Holcim Elevate is the name that replaced Firestone Building Products. We note both names in the file so the certificate and the manufacturer's current records can be matched to the roof.

Can an EPDM roof be repaired in winter?

Adhesives and tapes need clean, dry surfaces and workable temperatures. In deep cold we stop water with a temporary measure and schedule the permanent repair for a suitable day.

What happens to rooftop units on the Highway 16 corridor?

Within 500 feet of the highway, the city's area plan prohibits roof-mounted mechanical units on structures. Equipment plans and roof openings are settled with the building owner and the mechanical trade before roofing begins.

How is a loose edge detected?

By hand and by eye: the metal is pressed for movement, the sealant is checked for cracks, and fasteners are checked for backing out. Photographs of each edge section go in the file.

Does a recover leave the original membrane in place?

It does. The existing roof stays as a base, so moisture evidence must show dry insulation and a sound deck before the recover is specified.
