LandMark Exteriors' Hassle-Free Process

1. Consultation

Each project starts with a consultation or appointment where we learn about your needs. We’ll provide you with beautiful design options, as well as efficient ways to make the most of your money. We always advise our clients to visit one of our showrooms to see firsthand the quality product options available for their home improvement project.

2. Measurement

We visit your home and take initial measurements. After you’ve committed to work with LandMark, we return for a final measurement to ensure exact product sizes for installation. At that time, we’re happy to review the entire install process with you, the homeowners, so you know exactly what to expect with our expert installation process.

3. Product order

We order custom materials, and organize permitting matters. We work with the village/municipality of the client to get that pulled, and we communicate with the client every step of the way to ensure compliance.

4. Pre-finishing

We offer custom stain and paint matching so your new windows and doors can be pre-finished before they’re installed. Our professional painter then finishes off the details in your home after the product is installed!

5. Installation

Our certified installation experts follow manufacturer guidelines to ensure proper installation and extend full product warranties to our customers, guaranteeing long-lasting results. Everything we do is in line with product installation instructions.

6. Service

We have a high commitment to service and take pride in our work. LandMark has come a long way with service & warranty, and we are able to address service requests in a timely manner. All customers get product warranties, our 5-year labor warranty, and service up to a lifetime* depending on products.

FAQs

How much does a roof replacement cost in the Chicago suburbs?

The cost of a roof replacement in the Chicago suburbs typically ranges from $10,000 to $30,000, depending on the size of your home and the materials used.

For standard asphalt shingle roofs, pricing usually falls between $6.50 and $10.50 per square foot, with our average project around $19,000.

Every home is different, so we provide detailed estimates to give you an accurate, transparent price based on your specific needs.

From start to finish, most projects take 2–4 months, including planning, permits, and scheduling.

Here’s a breakdown:

  • Estimate & planning: 4–10 days
  • Roof installation: 1–2 days
  • Siding installation: 2–7 days

While the on-site work is quick, we take the time to ensure everything is done properly—from design to final inspection.

Yes! We offer flexible financing options through Service Finance to make your project more affordable.

  • Payments can start as low as ~$199/month
  • Most payments range from $100 to $3,000/month
  • Typical plans: ~1.3% of total project cost per month
  • Low fixed-rate options (e.g., 9.99% for 120 months)
  • No prepayment penalties

We also offer promotional plans like no payments and no interest for up to 12 months. Our team will help you find the best option for your budget.

We take care of full removal and cleanup as part of every project.

Here’s what to expect:

  • On-site dumpster placement
  • Careful protection of your property with tarps
  • Magnetic cleanup to remove nails and debris
  • Proper disposal of all materials

Yes—fiber cement siding (like James Hardie) is typically more durable for Illinois weather.

It performs better against:

  • Freeze-thaw cycles
  • High winds
  • Extreme temperature swings

It’s also more impact-resistant and less prone to warping or cracking. While vinyl siding is more budget-friendly, fiber cement is often the better long-term investment for Midwest homes.
