Alltek Roofing

Built Well Beyond "Bare Minimum"

A better roof starts before the first shingle is installed.

Most roofing companies are built on "good enough" standards. At Alltek, we’ve rebuilt the roofing process around five core beliefs that prioritize your home’s longevity over our bottom line.

Premium Materials

We are proud Atlas Signature Select Specialists. We don't use "builder grade" products. Alltek roofs feature Atlas shingles with ScotchGard™ Protector to fight ugly black algae streaks. Beneath the surface, we install high-performance underlayments built to handle Illinois’ brutal freeze-thaw cycle.

Premium Materials

“Code Plus” Standards

Building codes are the bare minimum required by law. In Chicagoland, "the minimum" isn't enough to survive decades of ice dams and high winds. Our "Code Plus" standard means we intentionally over-engineer every project, from installing double the required ice and water shield to color-matching every finishing detail.

“Code Plus” Standards

60-Minute Consultations

Our 60-minute consultation is a technical deep dive to identify ventilation gaps, mold, or structural rot before they become a crisis. You get a detailed “map” of your roof’s health and a transparent, on-the-spot quote. Then, we leave. We give you the space to make an informed decision on your own schedule, with zero sales pressure.

60-Minute Consultations

Our Core Values

As a family-owned business, our reputation is our most valuable asset. If we miss a vent or a piece of flashing in our initial quote, we don't hit you with an additional cost. Instead, we eat the cost. We believe in transparent communication, professional conduct, and treating your property with the respect it deserves.

Our Core Values

The Pursuit Of Better

The roofing industry is notorious for "we’ve been doing it like this for 30 years." We refuse to settle. By attending national conferences, utilizing modern satellite measurement technology, and staying at the forefront of building science, we provide a more precise, technically superior installation than companies stuck in the past.

The Pursuit Of Better
A Message From Thomas Sigle, Owner

Alltek Roofing: Built On Honesty And Doing The Job Right

I started Alltek Roofing because I was tired of the industry’s low standards. You know, lazy quotes… followed by even lazier workmanship.

At Alltek, we’ve replaced the “old-school” way of roofing with a brand-new experience for homeowners. Here’s what you can expect:

We don't spend time reading from a sales script. We spend our time in your attic and on your roof looking for leaks and broken wood.

Building rules are bare-minimum for us. We build to "Code Plus" standards on every job so your roof can handle the harsh Illinois winters.

If we miss a small detail in our price, we pay for it — not you. We stay honest about the cost from start to finish.

You can rest assured the work will get done right the first time. Period.

How We Build You A Better Roof

At Alltek Roofing, we don’t think “just enough” is good enough for your family’s home. Our "Code Plus" Standards mean we go beyond basic local requirements where it matters most.

1

Double The Ice & Water Shield

Many local building codes only require 3 feet of ice and water shield. In a heavy Illinois winter, that’s simply not enough. Alltek installs a full 6 feet of protection on every eave to ensure your home is armored against ice dams and moisture, no matter how deep the snow stacks up.

2

Precision Attic Ventilation

Most roofers just swap old vents for new ones. We take it a step further by calculating your attic’s specific "breathability" during our first visit. By engineering a ventilation system tailored to your home’s footprint, we prevent the wood rot, mold, and shingle degradation that cut a roof’s lifespan in half.

3

The "Signature Finish" Standards

We treat the finishing touches as an integral part of your roof. This includes color-matching your drip edges, painting lead pipes to blend seamlessly with your shingles, and a final magnet sweep to ensure your property is 100% safe for your family and pets.
