Where RIDGELOCK PRO Performs

Engineered for real job sites.

Residential roofing

Residential Roofing

New construction and re-roof projects rely on a clean, walkable underlayment that protects the deck before shingles or metal panels go on.

  • Steep-slope shingle roofs
  • Metal roofing systems
  • Tear-off and re-cover work

Commercial & Multi-Family

Larger roofs demand consistent roll quality, reliable logistics and documentation that satisfies inspectors and insurance carriers.

  • Apartment and condo projects
  • Light commercial buildings
  • Subdivision developments
Commercial roofing
Ice and water shield

High-Risk Detail Areas

Eaves, valleys, skylights, chimneys and low-slope sections need a self-sealing membrane that stops water where it is most likely to enter.

  • Eaves and rakes
  • Valleys and dormers
  • Low-slope transitions

Wall & Building Envelope

House wrap creates the breathable second skin that blocks wind and rain while letting walls dry out — critical for framed construction.

  • Wood-framed walls
  • Steel-frame structures
  • Retrofit and remediation
House wrap application
Radiant barrier

Attic & Energy Retrofit

Radiant barrier foil reflects heat away from living spaces, reducing cooling loads and improving comfort in hot climates.

  • Attic rafter applications
  • Metal building insulation
  • HVAC duct wrapping

Hurricane & High-Wind Zones

Coastal and high-velocity wind zones require underlayment that meets enhanced code requirements and stays in place under extreme conditions.

  • Miami-Dade/TAS areas
  • Secondary water barrier
  • Insurance mitigation programs
High wind roofing
Scenario 01

Residential Roofing

New construction and re-roof work, where the underlayment has to protect the deck from the moment the old roof comes off until the last shingle is nailed.

On a tear-off the deck is exposed the instant the old roof comes off. A synthetic underlayment gives crews a walkable, tear-resistant layer that holds up to foot traffic and sudden weather while the new roof goes on — which is the practical reason most residential crews moved away from felt.

The specification decision is usually an exposure decision. Match the weight to how long the roof will realistically stay open: lighter grades suit jobs that are shingled within days, heavier grades buy months of open time.

What specifiers ask for

  • A walkable anti-skid surface that protects crews on steep slopes
  • Tear strength that survives handling and wind loading before the roof is closed in
  • A documented UV exposure window that matches the build schedule

Scenario 02

Commercial & Multi-Family

Apartment blocks, condo projects, light commercial buildings and subdivision developments, where scale changes what matters.

Larger roofs change the problem. Volume, consistency and paperwork matter as much as the material itself — a subdivision or a condo block needs every roll to behave the same way, delivered on a schedule that keeps multiple crews working.

Phased work also stretches the exposure window. On a big deck that gets covered over several weeks, an under-specified UV rating or weak fastener holding becomes a schedule risk rather than a product detail.

What specifiers ask for

  • Consistent roll quality across the whole order, not just the sample
  • Documentation that satisfies inspectors and insurance carriers
  • Delivery scheduling that matches phased construction

Scenario 03

High-Risk Detail Areas

Eaves, valleys, skylights, chimneys and low-slope transitions — the places where water concentrates and shingles alone cannot seal.

Most leaks do not start in the middle of a roof. They start at the details, where water volume is highest and where a mechanically fastened roof covering leaves penetrations behind every nail and staple.

A self-adhering membrane handles these areas because the rubberized asphalt backing closes around each fastener instead of leaving a hole behind. It is a small fraction of the roof area, and it is where most callbacks come from.

What specifiers ask for

  • Self-sealing behaviour around fastener penetrations
  • Cold-temperature application to extend the working season
  • A split-back release liner to speed up long eave runs

Scenario 04

Wall & Building Envelope

The breathable second skin behind the cladding — the layer that decides whether a wall assembly can dry out or stays wet.

Behind the cladding, the wall needs a layer that keeps wind and bulk water out while still letting moisture vapour escape. Trap that vapour and the assembly has no way to dry; skip the barrier entirely and wind-driven rain reaches the cavity.

On framed construction the house wrap is both the drainage plane and the air control layer, and it has to survive weeks of handling, fastening and weather before the cladding goes on.

What specifiers ask for

  • Vapour permeance that matches the wall design
  • Tear resistance that survives handling and fastening
  • Enough UV stability to cover the gap before cladding

Scenario 05

Attic & Energy Retrofit

Radiant heat control for attics, metal buildings and mechanical runs — the retrofit that works without rebuilding the assembly.

In hot climates a large share of the cooling load arrives as radiant heat through the roof. A radiant barrier does not absorb that heat; it reflects it back across an air space before it reaches the insulation and the ceiling below.

That air gap is the part people miss. A reflective facing pressed directly against another material has nothing to reflect across, so performance collapses toward whatever contact conduction allows. Installation detail decides the result.

What specifiers ask for

  • Reflectivity and emissivity figures, not a generic energy-saving claim
  • An assembly detail that preserves the air gap
  • Cut-to-length supply to reduce offcut waste

Scenario 06

Hurricane & High-Wind Zones

Coastal and high-velocity wind zones, where the roof deck has to stay covered even if the primary roof covering is lost.

High-wind zones add two requirements on top of normal underlayment. The deck has to stay covered if shingles or panels are torn away, and the material has to stay in place under sustained uplift for as long as the storm lasts.

That is why self-adhered membranes are specified as a secondary water barrier at eaves and valleys, and why fastener-holding strength and the anti-skid surface matter more the steeper and more exposed the site.

What specifiers ask for

  • Secondary water barrier detailing at eaves and valleys
  • Fastener-holding strength appropriate to the wind zone
  • Documentation for insurance mitigation programmes

Specifying by climate and condition

ClimateUnderlayment for High-Wind and Hurricane RegionsIn a wind event the underlayment is the last line of defence once shingles lift. Tear strength and attachment are what keep the envelope closed. ClimateUnderlayment for Cold Climates and Ice Dam ProtectionIce dams back water up under the shingle course. The only underlayment that survives it is one that seals around its own fasteners. ClimateUnderlayment for Hot and Humid ClimatesIn hot-humid regions the deck has to dry, and the sheet may sit in full sun for weeks. Permeance and UV tolerance decide which product survives. Code & PracticeRoof Slope and Underlayment Layers: Single vs Double CoverageHow the 2:12 and 4:12 thresholds decide whether you need one layer or two, and what that does to material quantity. InstallationUnderlayment Fastening Patterns and Lap RequirementsA good sheet fastened badly fails. Attachment schedule, cap size and lap treatment decide whether the detail holds.
