5 Crucial Things to Know Before Replacing a Roof

Published On: May 25, 2025

Replacing your roof is a major decision — one that affects your home’s long-term safety, value, and energy efficiency. Whether you’re dealing with storm damage, an aging structure, or planning for an upgrade, knowing what to expect before the work begins is key to avoiding costly surprises. For homeowners in Granbury, TX, where weather conditions can range from intense heat to heavy rains and occasional hail, choosing the right materials and contractor is especially important.

At DT Roofing, we believe in empowering homeowners with knowledge so they can make confident, informed decisions. In this guide, we’ll walk you through the five most crucial things you should understand before starting a roof replacement project.

1. Roof Replacement Is More Than Just New Shingles

Many homeowners assume that replacing a roof simply involves removing the old shingles and nailing down new ones. While shingles are a major component, a proper roof replacement involves the entire roofing system — including the underlayment, flashing, ventilation, decking (if needed), drip edge, ridge caps, and more.

Your roof functions as a complete system, and each part must work in harmony to protect your home from water intrusion, wind uplift, and temperature extremes. If your contractor only focuses on the visible surface layer, they may be missing underlying issues that could reduce the lifespan of your new roof.

A quality roof replacement should begin with a comprehensive inspection to assess everything from your roof deck to attic insulation and ventilation. Addressing these components upfront ensures better performance and fewer issues in the future.

2. Not All Roofing Materials Are Created Equal

The type of material you choose plays a big role in your roof’s durability, appearance, and overall cost. In Granbury, it’s important to choose materials that hold up well to the Texas climate — which includes UV exposure, high winds, and seasonal storms.

Here are a few common options:

Asphalt Shingles – Affordable, versatile, and available in a variety of styles and colors. Architectural shingles provide better longevity and wind resistance than standard 3-tab shingles.

Metal Roofing – Offers superior durability and lasts 40–70 years. It reflects heat and can improve energy efficiency. Great for those who want a long-term, low-maintenance solution.

Synthetic Shingles – Mimic the look of natural materials like slate or wood while offering better impact resistance and lighter weight.

When comparing materials, consider lifespan, maintenance requirements, and manufacturer warranties. Also, make sure the materials are suitable for your roof’s pitch and structure.

3. Hire a Local and Trusted Roofing Contractor

Choosing the right contractor is just as important as selecting the right materials. A professional, reputable roofer will not only install your roof correctly but also ensure that all permits, codes, and warranties are properly handled.

In Granbury, storm-chasing companies often arrive after major weather events, offering cheap services and disappearing soon after. Avoid these risks by hiring a well-established local company that knows the area, the climate, and the local building regulations.

DT Roofing has a proven track record in Granbury and surrounding areas, and as a certified Owens Corning Platinum Preferred Contractor, we meet some of the industry’s highest standards for craftsmanship, training, and customer service. We also offer comprehensive warranties backed by the manufacturer for added peace of mind.

When choosing a contractor, look for the following:

  • Proper licensing and insurance

  • Solid local references and reviews

  • Clear written estimates and contracts

  • Manufacturer certifications

  • A no-pressure, informative consultation process

4. Understand the Full Cost Breakdown

Roof replacement costs can vary widely based on material, size, roof pitch, complexity, and other factors. Before committing to a project, make sure you receive a detailed written estimate that breaks down all components — including labor, materials, removal of old roofing, disposal fees, permits, and warranty coverage.

Be wary of unusually low quotes. These often indicate lower-quality materials, inexperienced labor, or hidden costs that may arise later. Remember, a roof is a long-term investment — saving a little today might end up costing you more in repairs or replacements down the road.

Ask your contractor to explain each line item and provide options for different materials or add-ons like upgraded ventilation or impact-resistant shingles. Knowing what you’re paying for ensures that there are no surprises once the work begins.

5. Timing, Weather, and Preparation Matter

While Texas weather allows roofing work most of the year, timing your roof replacement during dry, mild periods can help reduce delays and improve installation conditions. In Granbury, late spring or early fall is often ideal, as these months typically avoid the peak of both summer heat and storm season.

Prepare your home before the roofing crew arrives by:

  • Moving vehicles away from the work zone

  • Protecting landscaping and outdoor furniture

  • Removing fragile items from interior walls or ceilings

  • Notifying neighbors about the upcoming project

A roof replacement typically takes 1–3 days depending on the size and complexity of the job. Clear communication with your contractor helps ensure a smooth experience from start to finish.

Bonus Tip: Think Long-Term

When replacing your roof, it’s wise to think beyond just the next few years. Consider enhancements like:

  • Improved attic ventilation to reduce energy bills and extend shingle life

  • Impact-resistant shingles to help prevent storm damage

  • Upgraded underlayment for better moisture protection

  • Reflective materials to boost energy efficiency

Discuss these options with your contractor to find the right balance of cost and benefit for your specific needs.

I contacted DT Roofing after a satellite dish pulled a section of the roof up when the high winds blew it down. Parker Nelson came out, evaluated the damage, and came up with an estimate. He sat down and explained the whole process, the benefits of using DT Roofing instead of other roofers. His presentation and DT Roofing folder were full of important information outlining the company's awards, liability insurance, and material warranties. Upon inspection of the roof, Parker identified the roof had significant damage. He recommended contacting the insurance company to get them to inspect it. There was NO pressure ever, only assistance walking through the process. The insurance adjuster actually had more concerns than Parker mentioned. The adjuster stated the roof needed to be replaced. So that is what DT Roofing did for me. Every step of the way, everything Parker explained would happen, was exactly as he stated. DT Roofing crew did an excellent job protecting my property from damage during the install and Parker came back after the install to inspect (also around multiple times during install to supervise) my new roof and my satisfaction with the cleanup. The roof is beautiful, I also had gutters installed. I love them also, just another example of the quality of DT Roofing. Thank you, Parker and DT Roofing.

DT Roofing has been my go-to company for minor roof repairs and for a total roof replacement due to hail damage. Parker Nelson was the project manager for my roof replacement last month. He was in contact with me throughout the entire process. He worked with my insurance company to provide evidence of roof damage. He verified that all the work was done properly including the ancillary work (staining, painting, gutters, window screens). There were no surprise charges, and available upgrades were fully explained with no pressure to purchase. They even installed a higher grade of roof, which lowered my homeowner’s insurance premium. I cannot express the gratitude I have for Parker. He is just a good person, and that shined through in his dealings with me. Thank you, DT Roofing for a beautiful roof and for hiring people with integrity—like Parker.

Cannot say enough about the professionalism, and skill that DT posesses from the Project Manager on down to field installers. It was a pretty small roof as metal roofs go, but DT approached it as the most important project they had. Justin was great. He reacted to the upcoming rain and split the install schedule to make sure the work was done before the rains came. Miguel’s crew went right to work both days, and did a great job from start to finish. Finished 2 hours before the rains came and were very careful not to let the roof nails penetrate through the brand new 1/2” thick pine roof boards and be visible from the inside. Great job guys!

After the April tornado damage, I contacted DT Roofing, Justin Sherwood after a high recommendation by another family member. He assisted us with all roof replacement, gutters and metal replacement on my shop. I have never experienced a more thorough person to assist us during these repairs. We consider ourselves most fortunate that Justin was there for us. The expertise of the repairs is beyond reproach and completely supervised by Justin.
