The Handyhands Standard

A roof is only as good as the details nobody sees.

Most roofs don’t fail at the shingle — they fail at the valleys, the flashing, and the nails. We install the complete GAF system, top to bottom, on every roof we build. Here’s exactly what that means, and why it outlasts what most Houston roofers sell.

  • GAF Certified · Factory-certified installer
  • 10-Year · Workmanship warranty
  • Family-Owned · Houston since 2023

The short answer

What makes a complete roofing system different from a shingle-only install?

Most roofs are sold as shingles. A system is every layer working together: FeltBuster underlayment, StormGuard ice and water shield in the valleys, TimberTex hip and ridge, and balanced ventilation. The layers you never see keep the water out, and they are what unlock the GAF warranties.

Two roofs can look identical on day one.

Five years and a few Gulf Coast hailstorms later, they don’t.

The difference is almost never the shingle you can see from the street — it’s the system underneath it. The layer that keeps water out of your valleys. The membrane at every pipe and chimney. How many nails hold each shingle down when the next windstorm rolls through. The roofers who cut corners cut them here, where you’ll never catch it on a walkthrough — and where it quietly costs you a roof years early.

We built our standard the opposite way: the parts you can’t see get the same attention as the parts you can.

Anatomy of our system

What “the whole system” actually means

A complete roof is built in layers, and every layer has a job. Keep scrolling and we’ll put one together in front of you — from the deck up, in the order we actually install it — along with what typically gets skipped when a roof is priced to be the cheapest bid.

01

Deck inspection & re-nailing

Before anything goes down, we inspect the wood decking and re-nail it to code. Storms find weak decking first.

Builder-grade often skips straight to felt over whatever’s there.

Tear-off in the Champions area — half the deck still bare, half already sealed where the roof meets the wall. An open deck is the only moment anyone can actually inspect the plywood.
02

StormGuard ice & water shield

A self-sealing peel-and-stick leak barrier that goes down FIRST — at the eaves, in the valleys, and around every penetration. The exact spots where Houston roofs actually leak, sealed before anything else laps over it.

Builder-grade often relies on a bead of caulk and hopes.

Cypress, mid-install: underlayment across the open field, and the dormer valleys and rakes sealed separately before the decking beside them gets covered. Valleys move the most water on a roof, so they get their own waterproofing.
03

FeltBuster synthetic underlayment

A tear-resistant synthetic layer across the whole deck, lapped over the leak barrier — your roof’s secondary water barrier, far stronger than the paper felt it replaces.

Builder-grade typically uses generic 15# felt that wrinkles, tears, and breaks down.

04

Starter strips, properly

Purpose-made starter shingles with a factory adhesive stripe seal the eaves and rakes and lock down your first course against wind uplift.

Builder-grade sometimes cuts up field shingles as a shortcut — which doesn’t seal the edge the same way.

05

GAF Timberline HDZ + 6-nail pattern

Our standard architectural shingle, installed with GAF’s LayerLock technology and a 6-nail pattern for maximum wind resistance — not the 4-nail field-guess that leaves shingles vulnerable.

This is also what qualifies your roof for GAF’s enhanced warranties (see below).

06

Balanced ventilation

Before the caps go on, the ridge gets its vent. We calculate intake and exhaust — air in at the soffits, hot air out at the ridge — because trapped heat ages a Houston roof from underneath.

Builder-grade usually just reuses whatever venting was already there.

07

TimberTex hip & ridge caps

Premium, impact-resistant caps finish the hips and ridges over the vent — heavier and more durable than the cut-up 3-tab shingles often used to cap a roof on the cheap.

08

New metal, every edge & wall

New drip edge at the eaves and rakes, new step flashing woven at every wall and chimney — never re-used, never re-caulked. And a full magnetic nail sweep of your property when we’re done.

The finish is where pride shows.

The result

One sealed system — every layer doing its job.

Water sheds. Heat escapes. Nothing lifts in the wind. That’s what eight layers, installed in the right order, buy you — and all of it is backed in writing:

  • GAF WindProven™
  • 10-Year Workmanship

Same roofline. Very different roof.

Backed three ways, not one.

Because we’re a GAF Certified Contractor installing the complete qualifying system, your roof earns coverage most shingle-only installs simply can’t register.

GAF System Plus Limited Warranty

The enhanced manufacturer warranty on your GAF materials — available because we’re GAF Certified and install the qualifying GAF system, not the base coverage any roofer gets by default.

GAF WindProven™ Limited Wind Warranty

Our qualifying LayerLock shingle system unlocks WindProven — GAF’s wind coverage with no maximum wind-speed limitation. That matters on the Gulf Coast.

10-Year Workmanship Warranty

On top of the manufacturer coverage, our own written 10-year warranty covers the installation itself — the labor and craftsmanship. One roof, covered from the factory and from us.

Want to step it up?

Two paid upgrades are available on any system:

  • GAF Timberline UHDZ — our most advanced architectural shingle, with an even larger nailing zone and a richer profile.
  • GAF Timberline AS II (Class 4) — a Class 4 impact-resistant shingle built to stand up to hail. Class 4 roofs may also qualify you for an insurance premium discount — ask us, and see how we document it below.

Something almost no one else does

We document the whole job — so your insurance knows you have a new roof.

When we build your roof, we document the entire process — and we hand you a packet you can submit to your insurance company at renewal. It proves you have a new, up-to-date roof installed to manufacturer standards.

Why that matters: an up-to-date roof — especially one built with an impact-resistant Class 4 shingle like the AS II — can lower what you pay to insure your home. Most roofers hand you a final invoice and drive away. We hand you the paperwork that keeps working for you long after the last shingle goes on.

It’s the same reason homeowners trust us with their claims in the first place: we understand the insurance side of a roof as well as the roofing side.

Questions, answered

Before you choose a roofer

Does the complete system cost more than a basic re-roof?

Sometimes a little more up front than the cheapest bid — because we don’t skip the layers that make a roof last. What you’re buying is a roof that holds up through Houston storm seasons and carries real manufacturer and workmanship warranties, instead of one that’s quietly built to fail early. Most homeowners find it’s the better value over the life of the roof. We also offer financing.

Will my insurance cover a new roof?

Often, yes — if your roof has storm or hail damage, it may be a covered claim. It’s what we specialize in: we’ll inspect honestly, tell you whether you have a claim worth filing, and stand with you through the process.

How long will a roof like this last in Houston?

A properly installed GAF system with balanced ventilation is built to last for decades — and ventilation is a big part of why. Heat and trapped moisture are what age a roof early from underneath; we design the system to manage both.

What exactly does the warranty cover?

Three things: your GAF materials (System Plus), wind with no maximum speed limit (WindProven), and our own installation workmanship for 10 years. We register the manufacturer coverage for you and include it in your documentation packet.

What’s the difference between HDZ, UHDZ, and AS II?

HDZ is our standard architectural shingle and it’s an excellent roof. UHDZ is a step up in nailing zone and profile. AS II is our Class 4 impact-resistant option built for hail — and it may earn you an insurance discount. UHDZ and AS II are available as paid upgrades.
