The products we install — by name, by tier, by what the warranty actually says

Most contractor sites show you a wall of manufacturer logos. Logos don't tell you which product line you're getting, what separates the good tier from the better one, or what the warranty covers when something goes wrong. This page does. We install across the major manufacturers, so the specification gets matched to your house and your ownership horizon — not to a supply agreement.

Roofing

Shingles — CertainTeed, GAF, Owens Corning

All three are excellent manufacturers, and independent comparisons rate their architectural lines nearly equivalent. Where they differ is in the ladder above architectural, in the accessory systems, and in what it takes to unlock their top warranty tier. Full brand-by-brand comparison lives on the roofing page.

CertainTeed — the full residential lineup

CertainTeed is the deepest catalog of the three, and the one homeowners most often ask us to break down. The Landmark family alone runs five tiers, and the names sound close enough to be genuinely confusing at the kitchen table.

Product lineTypeWhat sets it apart
LandmarkArchitectural (dual-layer)The workhorse — the heaviest of the big three's standard architectural shingles, with the widest color range
Landmark PROArchitecturalThicker and heavier than Landmark, with an upgraded color palette
Landmark PremiumArchitecturalMore high-grade asphalt again — maximum dual-layer protection in the series
Landmark TLLuxuryTriple-laminate; the top of the Landmark series, with real depth of shadow line
Landmark ClimateFlexImpact-resistantRubberized polymers formulated to resist hail impact damage
Landmark PRO SolarisSolar-reflectiveReflective granules that shed summer heat load — worth pricing on a dark, sun-beaten roof
NorthGate ClimateFlexSBS-modifiedRubberized asphalt built for cold-weather flexibility and impact resistance
Grand ManorLuxurySlate look, five layers at the tab — the heaviest shingle CertainTeed makes
BelmontLuxurySlate-look designer profile at a step below Grand Manor
Presidential Shake / Presidential TLLuxuryHand-split shake appearance; TL is the triple-laminate version
Solstice / SunStyleSolar roofingSolar shingles and panels for homeowners folding generation into a re-roof
XT 253-tabFlat-profile budget shingle — mostly a rental-property and outbuilding choice now

CertainTeed also builds the rest of the roof: underlayment, ice-and-water barrier, starter course, hip-and-ridge caps, and ridge, intake and soffit ventilation. Specify all of it together and you have what CertainTeed calls an Integrity Roof System — which is the precondition for their extended SureStart PLUS coverage. See certainteed.com/residential-roofing.

GAF and Owens Corning

Official product references: gaf.com · owenscorning.com/roofing. Metal is the fourth option and doesn't ladder the same way — standing seam runs two to three times the cost of architectural shingles and lasts 40–70 years, which is the whole argument for it.

Decking & railing

Railing ladders separately — composite to match your boards, powder-coated aluminum for slim sightlines, cable for an unobstructed view. The decks page works through wood-vs-composite cost of ownership in detail.

One caution worth more than any board upgrade: fade-and-stain warranties cover the surface, not the structure underneath. Joist tape and sound framing decide how long the deck lasts, because a 50-year board on a rotting frame lasts exactly as long as the frame.

Which tier is right is usually settled by two numbers rather than by the badge: U-factor at or below 0.30 and SHGC around 0.40 for our mixed climate. The windows & doors page explains both, plus frame-material trade-offs.

Behind the drywall

Insulation and board — the part nobody photographs

On a basement finish or a garage conversion, the products that decide whether the room is comfortable in February are all buried in the wall. CertainTeed makes most of them: fiberglass batts and rolls, SMARTBATT with an integrated smart vapor retarder for humidity-prone spaces, InsulSafe SP premium blown-in for attics, and AirRenew indoor-air-quality gypsum board. Below-grade walls also want a capillary break and a vapor strategy before any of it goes up — that sequencing is on the basement page.

Read this before you pay for a warranty tier

What a manufacturer warranty actually covers

Every warranty on this page covers one thing: defects in the product itself. Not installation errors. Not flashing leaks. Not storm damage. Those are covered by the contractor's written workmanship warranty and by your homeowner's policy — which is why the workmanship terms deserve the same scrutiny as the brand.

Three things worth knowing before a salesperson quotes you a warranty number:

What we'll tell you at the estimate: which product line we're specifying, what its baseline warranty actually is, and what the upgrade would buy you. If a tier isn't worth the money on your house, we'll say that too.

Straight answers

Product questions, answered

What brands does CORELOT install?

Roofing: CertainTeed, GAF and Owens Corning shingles, plus standing-seam and panel metal. Decking: Trex, TimberTech/AZEK, Fiberon and pressure-treated lumber. Windows and doors: Andersen, Pella, Marvin, ProVia and Simonton. Siding: James Hardie, LP SmartSide and CertainTeed. We aren't locked to one manufacturer, so the product gets matched to your house, exposure and horizon rather than to a supply agreement.

What's the difference between CertainTeed Landmark, Landmark PRO and Landmark Premium?

Same family, progressively more asphalt per shingle. Landmark is the standard dual-layer architectural shingle; PRO is thicker and heavier with an upgraded color range; Premium adds more high-grade asphalt again for maximum dual-layer protection. Above them: Landmark TL, a triple-laminate luxury shingle, and Landmark ClimateFlex, formulated with rubberized polymers to resist hail impact.

What is a CertainTeed Integrity Roof System?

A roof where the shingles, underlayment, ice-and-water barrier, starter course, hip-and-ridge caps and ventilation all come from CertainTeed and are installed as one system. Specifying the complete system is what makes a roof eligible for extended SureStart PLUS coverage — which also requires a CertainTeed-credentialed contractor.

Do I need a certified installer to get the best manufacturer warranty?

For the top tiers, yes. Programs like SureStart PLUS 4-STAR and 5-STAR are sold only through manufacturer credentialing programs, and the credential belongs to the contracting company. Ask to see it in writing — from us or from anyone else — before paying a premium for a tier that depends on it. Baseline manufacturer coverage on the product itself applies to any correct installation.

Does the brand or the installation matter more?

Installation, and it isn't close. Underlayment, flashing, ventilation and fastening decide how a roof ages; joist protection and framing decide how a deck ages; flashing and clearance details decide how siding ages. A quality mid-tier product installed correctly outlasts a premium product installed poorly, every time.

Can I mix brands within one project?

Physically yes, and it's common on repairs. But enhanced system warranties are the exception — CertainTeed, GAF and Owens Corning all require their own accessory components throughout before their upgraded coverage applies. If the extended warranty is the thing you're buying, the whole assembly has to come from one manufacturer.

Product lines and warranty terms change; the details here were verified against manufacturer sources in September 2026. We'll confirm the current terms for whatever we specify on your estimate.
