Frequently asked

Glossary

1

Low-slope roofing

Roof assemblies with a pitch shallow enough that water drains slowly, typically 2:12 or less, common on commercial and industrial buildings; the systems shown at the RCAT tradeshow include single-ply membrane and modified bitumen.

2

Steep-slope roofing

Roofs with a pitch generally above 4:12, the segment where residential shingles, metal panels, tile and synthetic underlayment are used.

3

TPO (thermoplastic polyolefin)

A white or light-coloured single-ply membrane heat-welded at the seams, widely used on low-slope commercial roofs for its reflectivity and resistance to ponding water.

4

EPDM

Ethylene propylene diene monomer, a black synthetic rubber membrane installed with adhesive or tape seams on low-slope roofs; known for flexibility and long service life.

5

Modified bitumen

A rolled asphalt sheet reinforced with polyester or fiberglass and modified with APP or SBS polymers, torched or adhered in overlapping plies on low-slope decks.

6

Membrane

The continuous waterproofing layer of a low-slope assembly - TPO, EPDM, PVC or modified bitumen - that keeps water out of the building.

7

Flashing

Metal or membrane detailing at roof edges, walls, curbs, penetrations and valleys that directs water away from joints; a frequent source of leaks and a common tradeshow product category.

8

Underlayment

The secondary water-shedding layer beneath shingles, tile or metal on steep-slope roofs, available as felt or synthetic sheet.

9

Roof deck

The structural surface - plywood, OSB, steel or concrete - that carries insulation and the roofing membrane or shingle assembly.

10

R-value

A measure of thermal resistance used to compare roof insulation, such as polyiso cover board assemblies specified for commercial energy-code compliance.

11

UL 2218 Class 4

The impact-resistance rating for roofing products that withstand a steel ball drop test; Class 4 shingles are commonly tied to insurance premium discounts in hail-prone Texas markets.

12

Wind uplift

The upward force wind exerts on a roof assembly, addressed with fastener patterns, plate count, adhesive and perimeter detailing tested to factory mutual or UL standards.

13

Drip edge

The metal strip at eaves and rakes that sheds water clear of the fascia and helps protect the deck edge from rot.

14

Tear-off

Removal of existing roofing down to the deck before installing a new assembly; drives labour and disposal costs on re-roof projects discussed on the show floor.

15

Change order

A written amendment to a roofing contract for added or changed scope, such as deck repairs found during tear-off, priced before work continues.

16

Retention

The percentage of a contract amount held back by the owner until the roofing project is accepted, typically released after punch-list completion.

17

Punch list

The final itemised list of incomplete or defective work a contractor must close out before the owner releases retention on a roofing job.

18

Lien waiver

A document in which a contractor or supplier gives up the right to file a mechanic's lien for a stated amount, commonly required before final payment on Texas roofing projects.
