We replace aging flat and low-slope roofs with modern, watertight systems that prevent pooling and leaks, ideal for additions, garages, or modern home designs.
When Is It Time to Have Your Roof Replaced?
Ignoring roof damage can lead to bigger, more expensive problems. Here are signs it’s time to consider a full replacement:
Curled or Missing Shingles
Shingles that are lifting or falling off leave your roof vulnerable to moisture and rot.
Frequent Leaks
If patch jobs aren’t holding, your roof’s protective layers may be too compromised.
Widespread Granule Loss
Bare shingles can’t block UV rays or water, leading to quick deterioration.
Sagging or Soft Spots
A sagging roof may indicate serious structural damage below the surface.
Roof Age (20+ Years)
Even if problems aren’t visible, older roofs are more likely to fail suddenly.
What Are the Benefits of Having Your Roof Replaced?
Replacing your roof is a major investment—but it pays off in big ways.
Enhanced Protection
A new roof ensures your home is safe from storms, moisture, and temperature swings.
Increased Energy Efficiency
Modern materials and improved insulation can lower your heating and cooling bills.
Boosted Curb Appeal
A new roof instantly elevates the look—and value—of your home.
Peace of Mind
No more constant repairs, leaks, or emergency calls—just reliable protection.
Improved Warranty Coverage
New roofs come with updated warranties, offering added security for years to come.
Roof Replacement FAQs
Close
How long does a roof replacement take?
Most residential roof replacements take between 1–3 days, depending on the size of your home and the type of materials being installed. We work efficiently while maintaining strict quality standards to get your home protected quickly.
Will my old roof be removed before the new one is installed?
Yes. We always perform a full tear-off to properly inspect the roof deck and ensure your new system is built on a solid, damage-free foundation. This approach ensures longevity and helps prevent hidden issues.
Do I need to move out during a roof replacement?
Not at all. While roofing can be noisy, you can remain in your home throughout the process. We’ll communicate clearly about what to expect and keep the work area clean and safe.
Can you help with insurance claims for storm damage?
Absolutely. We have experience working with insurance providers to help homeowners navigate roof replacement claims after wind, hail, or storm damage. We provide clear documentation and advocate for your needs.
At A-1 Contractors, Inc., we’ve built our reputation on integrity, skill, and results. For over 20 years, Great Falls homeowners have trusted us to provide roofing solutions that are built to last.

We recently had A-1 re-do our vinyl flat roof on our home. They were great. They were prompt, professional and the price was exactly what they quoted us. … More The work is done well, and they are giving us a 5-year warranty on workmanship. The employees who showed up were courteous and friendly. This was a big and expensive job, and they were really top notch. I have no problem recommending them.

- I was also impressed with their punctuality on the job site. The crew had arrived on time and within 5-10 minutes of their arrival our old roof was being taken off.
- Every single crew member addressed us as “Sir” and/or “Ma’am” and had a smile on their face the entire time. It was very apparent that they liked each other and their job. There was a sense of pride amongst their team and it showed in their work.
- Finally, our roof was completed in 2 days and our yard was left cleaner than when they arrived!! I couldn’t be more impressed. -
