A roof replacement is one of the largest investments a homeowner makes. We take that seriously. We never recommend replacement when repairs will solve the problem, and we help you understand all your options so you make the best decision for your home and budget.
When to Replace vs. Repair Your Roof
After inspecting thousands of Mesa roofs over four decades, here are the situations where replacement makes more sense than repair:
Replace When:
- Shingle roof is 20+ years old with widespread deterioration
- Tile roof has failed underlayment across most of the roof area
- Multiple leaks in different areas despite previous repairs
- Roof decking has water damage or rot in multiple locations
- Repair costs exceed 50% of replacement cost
- You plan to sell your home and need a roof that passes inspection
Repair When:
- Damage is isolated to one area (storm impact, single leak)
- Roof is under 15 years old (shingle) or 25 years old (tile)
- Only a few tiles or shingles need attention
- Flashing or sealant has failed but roofing material is sound
- Flat roof coating needs refresh but membrane is intact

Roof Replacement Options for Mesa Homes
Tile Roof Replacement
Tile is the most popular choice for Mesa homes. Options include concrete tiles (most common, 30-50 year lifespan) and clay tiles (premium, 50-100+ years). We handle complete tear-off, new underlayment, and tile installation. More about tile roofing.
Best for: Long-term homeowners wanting maximum durability in Arizona heat.
Shingle Roof Replacement
Architectural shingles provide good protection at a lower cost than tile. We install heat-rated shingles from GAF, Owens Corning, and CertainTeed with 20-30 year warranties. More about shingle roofing.
Best for: Budget-conscious homeowners or those planning to sell within 15-20 years.
Flat Roof Replacement
For flat sections, patios, and carports, we install modified bitumen, TPO, or elastomeric coating systems. Each has different advantages depending on your specific situation. More about flat roofing.
Best for: Low-slope or flat roof sections, patio covers, and commercial applications.
Our Roof Replacement Process
- Free inspection and estimate -- We assess your current roof, identify all issues, and provide a detailed written estimate with material options and pricing.
- Material selection -- We help you choose the right roofing material for your home, budget, and HOA requirements. We bring samples and explain the pros and cons of each option.
- Permits and scheduling -- We pull all required City of Mesa building permits and schedule your project for optimal weather conditions.
- Tear-off -- We remove the existing roofing material down to the decking, inspect the decking for damage, and replace any compromised sections.
- Underlayment installation -- We install new waterproof underlayment -- the critical layer that protects your home from water intrusion.
- New roofing installation -- We install your chosen roofing material according to manufacturer specifications and local building codes.
- Flashing and detail work -- We install new flashing around all penetrations (AC units, vents, pipes, chimneys) and seal all transitions.
- Cleanup and final inspection -- We remove all debris, run magnets for stray nails, and perform a final quality inspection. We schedule the city inspection if required.
Arizona-Specific Replacement Considerations
Replacing a roof in Mesa is different from replacing one in a cooler climate. With average summer highs of 104-115 degrees Fahrenheit and roof surface temperatures reaching 150-170 degrees, here is what matters most:
- Underlayment quality matters more here -- Arizona heat is the primary enemy of roofing underlayment. We use high-quality synthetic underlayment that withstands extreme temperatures better than traditional felt paper.
- Ventilation is critical -- Proper attic ventilation reduces roof surface temperatures by 20-40 degrees, dramatically extending your new roof's lifespan. We assess and improve ventilation as part of every replacement.
- Heat-rated materials -- Not all roofing products perform equally in Arizona. We select materials specifically rated for extreme heat and UV exposure.
- Timing matters -- Fall through spring (October-May) is the ideal time for roof replacement in Mesa. We avoid scheduling during the hottest summer months when extreme heat affects both crew safety and material handling.
- Monsoon readiness -- If replacement is needed during or before monsoon season, we ensure your home is fully protected at the end of each work day.
Frequently Asked Questions
How long does a roof replacement take in Mesa?
Most residential roof replacements take 3-5 days, depending on roof size, material type, and complexity. Shingle-to-shingle replacements are typically faster than tile work. Larger homes or homes with complex roof lines may take up to a week. We provide a specific timeline with every estimate and keep you updated throughout the project.
Do I need to be home during roof replacement?
You do not need to be home the entire time, but we recommend being available on the first morning (to review the project plan) and at completion (for final walkthrough). During the work, our crew is self-sufficient. We ask that vehicles be moved from the driveway and that pets be kept inside due to noise and debris.
Does a new roof increase home value in Mesa?
Yes. A new roof typically increases a Mesa home's value and makes it significantly easier to sell. Buyers and home inspectors in Arizona pay close attention to roof condition because of the climate's impact on roofing. A new roof also eliminates a major negotiation point during home sales.
Can I replace just part of my roof?
In some cases, yes. If one section of your roof has failed while the rest is in good condition, a partial replacement can make sense. This is common with tile roofs where only certain sections need new underlayment. However, mixing old and new shingles is generally not recommended due to color matching and warranty issues. We assess each situation individually.
