Hiring the right residential roofing contractor is one of the most important decisions a homeowner can make. Whether you’re planning a full roof replacement or simple repairs, working with a qualified, trustworthy professional can make all the difference. But how do you know which contractor is reliable and which might leave you with leaks and regrets? In this guide, we’ll walk through the key factors to look for in a residential roofing contractor to protect your investment and your home.


1. Start With Licensing, Insurance, and Certifications


A reliable roofing contractor should always be licensed, insured, and certified. Licensing ensures they meet your state’s standards for competency and legality, while liability insurance protects you if property damage or worker injuries occur during the project. Certification from manufacturers (like GAF or CertainTeed) also indicates a contractor is trained to install their products properly. According to the National Roofing Contractors Association (NRCA), verifying credentials before signing a contract is one of the top homeowner safeguards. Reputable contractors like Dillman Brothers provide clear documentation of all required credentials and welcome questions about compliance and coverage.

Fun Fact: Did you know that asphalt shingles remain the most popular roofing material in the U.S., accounting for roughly 80% of the residential market? Their balance of affordability, durability, and style makes them a top choice for homeowners.

2. Choose Experience and Local Knowledge


Experience matters in roofing. A contractor with years in the industry has likely encountered a wide variety of roofing challenges and can quickly assess and resolve issues. Even more important is local knowledge. A roofer who understands the regional weather patterns, building codes, and permitting requirements can tailor their recommendations accordingly. For instance, someone familiar with Midwest winters might suggest specific materials better suited to snow and ice. Dillman Brothers, serving homeowners for decades, are well-versed in the unique roofing needs of the region and offer guidance tailored to each home’s location and climate.


3. Look for Transparent Estimates and Contracts


Clear communication around pricing is non-negotiable. A reliable roofing contractor should offer detailed written estimates that break down materials, labor, warranties, and any contingencies. Avoid vague or verbal quotes that leave too much room for surprise charges. Contracts should include timelines, payment terms, and a cleanup plan. According to HAR.com, homeowners should compare multiple estimates and avoid the cheapest bid, which can be a red flag. Contractors like Dillman Brothers provide itemized estimates and are upfront about all project costs, ensuring you know exactly what you’re paying for.


4. Evaluate Past Work and Customer Reviews


Customer reviews are one of the best indicators of a roofing contractor’s reliability. Look for consistent patterns of satisfaction or complaint across platforms like Google, Yelp, and the Better Business Bureau. High-quality roofers are also proud to show you photos of completed projects or connect you with past clients for references. Visual proof of workmanship builds trust. Dillman Brothers, for example, showcase a portfolio of residential roofing jobs and maintain excellent reviews from satisfied homeowners, praising both the quality of work and communication throughout the process.

  • How long does it typically take to install a new roof?

    Most residential roofs can be installed in 1–3 days, depending on the size and complexity of the project.

  • Do I need to move out during roof replacement?

    No, most homeowners can stay in their homes, although noise and vibrations are common during installation.

  • What’s the best time of year to get a new roof?

    Spring through early fall is ideal due to favorable weather, though professional contractors can install year-round.

5. Ask About Warranties and After-Service Support


A reliable contractor should offer strong warranties on both labor and materials. Manufacturer warranties often cover materials for 20–50 years, but a separate workmanship warranty—typically 5–10 years—protects you if installation issues arise. The best roofing companies stand by their work long after the job is complete. According to Consumer Reports, clear warranty information is a sign of a contractor’s long-term commitment. Dillman Brothers not only offer competitive warranties but also provide responsive service if concerns arise after the job is done, giving homeowners peace of mind.


6. Communication and Professionalism Matter


From the initial consultation to the final cleanup, professional behavior is essential. Does the contractor return calls promptly? Do they show up on time and answer your questions thoroughly? Poor communication can lead to misunderstandings, delays, and frustration. A dependable roofing contractor sets clear expectations, communicates project updates regularly, and treats your property with respect. At Dillman Brothers, customers consistently report professional interactions, timely scheduling, and helpful support throughout the roofing process.


7. Prioritize Safety and On-Site Protocol


Roofing is inherently dangerous work. A reliable contractor will prioritize safety for both their crew and your household. This includes using harnesses, edge guards, and safety training for all workers. Ask whether the contractor follows OSHA safety standards and what safety measures will be in place during your project. Contractors like Dillman Brothers take safety seriously, with trained crews and protocols that protect both personnel and property. When safety is taken seriously, you can trust the work will be too.


8. Recommend an Experienced Residential Roofing Contractor With Good Reviews


If you're in the market for a trustworthy residential roofing contractor, it's crucial to choose one with experience, positive customer feedback, and a solid reputation. Dillman Brothers check every box: decades of industry experience, glowing local reviews, transparent pricing, and responsive service. Their team is known for handling every step of the process professionally, from inspection to cleanup.

Ultimately, the best residential roofing contractor is the one you can trust. Beyond credentials and warranties, the contractor’s integrity, responsiveness, and track record should give you confidence. You’re not just investing in a roof—you’re investing in your home’s protection for the next 20–30 years. Take time to vet each candidate, ask detailed questions, and request documentation.

What Happens If There’s an Issue After the Renovation Is Completed?

August 12, 2025
Highlights: Post-renovation issues may be covered under workmanship or manufacturer warranties. Reputable contractors offer service guarantees and prioritize customer satisfaction. Proper documentation and communication are key to resolving post-renovation problems. Understanding your contract terms helps manage expectations and timelines. Dillman Brothers serves homeowners in Urbana, IL with reliable post-project support and follow-through. Understanding Post-Renovation Problems Finishing a home renovation is exciting, but what happens if something goes wrong after the project is complete? From cracked siding to leaky windows, post-renovation issues are not uncommon. Homeowners in Urbana, IL should know what to expect when dealing with these problems. The outcome often depends on your contractor’s policies, your warranty coverage, and the nature of the issue. Being informed about your rights and the contractor’s responsibilities helps protect your investment. Companies like Dillman Brothers understand the importance of standing behind their work and assisting clients even after the final payment is made, ensuring long-term peace of mind. Workmanship Warranty Coverage One of the first things to examine is whether the issue falls under a workmanship warranty. Reputable contractors usually offer these warranties for a specific period—often one to five years—covering labor-related problems like loose fixtures or structural errors. If a contractor guarantees their workmanship, they are typically obligated to return and fix the issue at no additional cost. According to the Federal Trade Commission , it's critical to get all warranty information in writing before your renovation begins so you understand what is and isn’t included in the service agreement. Manufacturer Warranties on Materials In some cases, the problem may stem from the materials used rather than the contractor’s labor. For example, siding, windows, or roofing shingles may come with manufacturer warranties. These warranties vary in length and scope but generally cover defects that result from faulty manufacturing. Many manufacturers require that products be installed by certified or approved contractors in order for the warranty to remain valid. It’s important to review the manufacturer’s terms and confirm the contractor’s credentials before finalizing any installation agreements to avoid surprise exclusions.

How Does Vinyl Siding Compare to Other Materials Like Wood or Fiber Cement?

August 11, 2025
Highlights: Vinyl siding is cost-effective and low-maintenance compared to wood or fiber cement.  Wood siding offers natural beauty but requires more upkeep and is susceptible to rot. Fiber cement provides durability and fire resistance but at a higher price and labor cost. Each siding material offers unique pros and cons based on budget, aesthetics, and climate. Dillman Brothers provides expert siding consultations in Urbana, IL to help homeowners make informed decisions. Understanding the Basics of Vinyl Siding Vinyl siding is made from polyvinyl chloride (PVC) and has become a popular choice for homeowners due to its affordability and low maintenance requirements. It is available in a wide variety of colors and styles, making it adaptable for various architectural designs. One of its key advantages is that it does not require painting, staining, or sealing—tasks that are often necessary with other siding materials. In Urbana, IL, where seasonal weather changes are common, vinyl siding’s resistance to moisture and UV rays makes it an appealing option for long-term durability. Comparing Cost and Installation Requirements Vinyl siding is typically less expensive to purchase and install than wood or fiber cement. According to Modernize , the average cost for vinyl siding ranges between $3 and $8 per square foot, while fiber cement can reach up to $13 and wood can range from $6 to $12. Labor costs for vinyl are also lower because it's lightweight and easier to install. In contrast, fiber cement requires specialized tools and safety gear due to the presence of silica dust during cutting. This difference makes vinyl more budget-friendly for most Urbana, IL homeowners. Maintenance and Upkeep Differences One of vinyl siding’s strongest selling points is its low maintenance. Unlike wood, which requires frequent sealing, painting, or staining to prevent decay and insect infestation, vinyl siding can be cleaned with just soap and water. Fiber cement, although more resistant to rot and pests, still needs periodic repainting and inspection for caulked seams. According to the International Association of Certified Home Inspectors (InterNACHI) , vinyl siding can last 20–40 years with minimal upkeep. Homeowners seeking convenience often lean toward vinyl when weighing their long-term commitments.

The Environmental and Economic Benefits of Roofing Material Recycling

August 8, 2025
Highlights Recycling roofing materials conserves energy, reduces pollution, and preserves natural resources. Contamination and improper sorting can undermine roofing recycling efforts. Plastic and composite roofing components pose unique recycling challenges. Roofing material recycling supports job creation and local economic development. Dillman Brothers leads sustainable roofing practices throughout Urbana, IL. Environmental Benefits Of Roofing Material Recycling Roofing companies like Dillman Brothers in Urbana, IL are embracing recycling programs to help reduce environmental impact. Asphalt shingles, metal panels, and underlayment materials often end up in landfills after roof replacements. However, recycling these materials reduces the need for mining and manufacturing new ones, conserving energy and minimizing greenhouse gas emissions. According to the U.S. Environmental Protection Agency (EPA) , recycling just one ton of paper can save 17 trees and 7,000 gallons of water—similar benefits apply when reducing construction waste. By recycling roofing debris, Dillman Brothers helps promote cleaner air and water throughout the community. Energy And Resource Conservation In Roofing Recycling asphalt shingles and metal from roof replacements saves substantial amounts of energy. Creating new metal roofing from raw ore consumes far more energy than using recycled metal. For example, producing recycled aluminum takes 95% less energy compared to extracting it from bauxite ore. In Urbana, IL, Dillman Brothers contributes to energy conservation by sorting and recycling roofing waste at designated facilities. This practice reduces the environmental costs associated with manufacturing new construction materials and supports a more sustainable building industry. Limitations Of Current Roofing Recycling Systems While roofing recycling offers many benefits, challenges remain. Contamination—such as leftover nails, tar paper, or wet insulation—can make materials harder to process. In some cases, entire loads are rejected due to improper sorting. According to the Natural Resources Defense Council (NRDC) , about 25% of items placed in recycling bins are not recyclable and often go to landfills. Dillman Brothers addresses this issue through proper waste separation and staff training. They also educate homeowners on what can be reused or recycled after a roofing project to maximize program success in Urbana, IL.

What Are the Best Home Layout Designs for Families?

August 7, 2025
Highlights: Open floor plans allow for better family interaction and line-of-sight supervision. Split-bedroom and multi-generational layouts support privacy and flexible living arrangements. Drop zones, large mudrooms, and dual-purpose spaces increase daily efficiency. Design choices should support both current needs and long-term growth. Dillman Brothers provides expert home design insight for families in Urbana, IL. Open Floor Plans for Connection One of the most popular home layout designs for families is the open floor plan. By removing barriers between the kitchen, living, and dining areas, this design encourages communication, visibility, and shared time. Parents can prepare meals while keeping an eye on kids or entertain guests without feeling isolated. Open layouts are ideal for modern lifestyles and often feature natural light, multifunctional furniture, and seamless transitions between spaces. According to Fairview Custom Homes , open-concept floor plans improve traffic flow, increase natural light, enhance visibility across shared spaces, and make smaller homes feel more spacious-key advantages for growing families. Dedicated Private Zones While openness is important, privacy also plays a big role in family living. Split-bedroom layouts separate the master suite from children's or guest rooms, giving everyone their own retreat. This setup works well for families with teenagers or multi-generational households. Sound privacy and independent access to bathrooms enhance comfort and reduce disruptions. Parents may enjoy a quiet master retreat while kids can share a wing of the home. These layouts can also include separate entrances or bonus rooms for aging parents or college-aged children living at home. Functional Entryways and Drop Zones A clutter-free home starts at the entrance. Family-focused layouts often feature drop zones or mudrooms that act as command centers. These areas include hooks for backpacks, cubbies for shoes, and benches for putting them on. Built-in storage and charging stations help organize daily essentials like keys, school forms, and electronics. According to Bluegrass Haven Construction , thoughtfully designed entry or mud zones serve as a buffer between outdoor chaos and living areas, providing dedicated space to shed coats, muddy shoes, backpacks, and sports gear-helping to maintain cleanliness and reduce daily clutter. In Urbana, IL, Dillman Brothers can incorporate practical solutions like these into local home layouts.

Highlights: Garage door replacement can offer one of the highest returns on investment for home improvement projects. Curb appeal and energy efficiency both contribute to increased resale value. Dillman Brothers serves Urbana, IL, with garage door upgrades that align with long-term property goals. Why Garage Doors Matter for Resale Value  Homeowners in Urbana, IL often look for ways to improve their property value before selling. While roofing and siding upgrades are common, many overlook the garage door. Yet, this single exterior feature can have a significant impact on a home's resale value. The right garage door enhances curb appeal, boosts energy efficiency, and contributes to first impressions, which are crucial in competitive housing markets. This is especially relevant in local markets like Urbana, IL, where exterior appeal can greatly influence buying decisions. According to Remodeling Magazine’s 2024 Cost vs. Value Report , garage door replacement consistently ranks among the top home improvement projects for return on investment (ROI). Homeowners can recoup over 102% of the cost at resale, showing that it's not just aesthetic—it’s strategic. This makes it a financially smart choice for homeowners preparing to list their property. Modern garage doors are more than just functional barriers. They offer sleek, insulated designs, quiet operation, and smart technology integration.

These features also add long-term value by improving convenience and home efficiency.
