Roof Replacement in Casa Grande
We replace roofs on older homes from the deck up. That means tearing off every old layer, repairing the sheathing underneath, and installing new underlayment, flashing and vents, so the new roof is not sitting on decades of past patches and worn parts.
When replacement is the right call
A roof needs replacing when the problem is the whole system, not one spot. On older homes that usually means the underlayment has dried out and cracked, the decking has soft areas, or several rounds of past repairs have left a roof that leaks somewhere new every season. Patching at that point buys a few months while you keep paying for repairs.
Older roofs also hide things. Tear-off regularly uncovers an earlier shingle roof still in place beneath the current one, galvanized valley metal rusted through, lead pipe jacks the sun has split open, or plywood that has delaminated around the curb of an old swamp cooler. A replacement is the one chance to correct all of it at once.
If the trouble really is isolated, we will tell you so and point you to our roof repair service instead. If you want to change materials, we can walk you through tile roofing, shingle roofing, foam roofing and flat roofing options for your home.
What a full replacement includes
Complete tear-off
We remove every existing layer down to the sheathing, including any old shingle layers left behind by earlier roofers. Extra layers add weight and hide rot, so they do not stay.
Deck repair and re-nailing
We replace soft or delaminated plywood and re-nail loose boards. On tile roofs with old skip sheathing, we explain whether solid decking is needed for the new underlayment and material.
New underlayment
Underlayment is the real water barrier under tile and shingles. Old felt bakes brittle in desert heat and cracks at the laps, so we install new underlayment matched to the roof covering you choose.
Flashing, drip edge and pipe jacks
Many older homes have no drip edge and worn lead or rubber pipe boots. We install new drip edge, valley metal, wall and chimney flashing, and pipe jacks rather than reusing tired parts.
Ventilation correction
Undersized or blocked attic vents cook the underside of a roof and shorten its life. We check intake and exhaust and add or replace vents so the attic can breathe.
Cleanup and haul-away
We tarp landscaping, protect the walls and AC equipment, run magnets for nails, and haul off all debris when the job is done.
Signs your roof needs replacing, not another patch
- Leaks keep moving
- A fix in one spot is followed by a stain somewhere else. That pattern points to failed underlayment across the roof, not a single bad flashing.
- Spongy or sagging areas
- A deck that gives underfoot or a ridge line that dips usually means sheathing has rotted from long-term moisture. That wood has to come out.
- Brittle shingles or cracked felt under tile
- Shingles that crack when bent or shed granules heavily are at the end of their life. Under tile, cracked felt visible at the eaves means water is reaching the deck.
- Layers of old repairs
- Roof cement smeared over flashing, mismatched shingles and tar around every penetration show a roof held together by patches.
- Two roofs stacked on one
- If your home already has a layover, another repair is working against added weight and hidden damage below.
How a replacement job runs
- 1
Look at the roof and the attic
We walk the roof and check the attic for decking condition, ventilation and earlier repairs. Afterward you receive pictures of each problem spot along with an itemized written estimate that spells out every part of the job.
- 2
Permit and materials
We pull the building permit the city requires and order materials. We confirm the start date with you and plan around summer heat and monsoon season where we can.
- 3
Tear-off and deck work
We strip the roof one section at a time, repair the deck as we go, and keep exposed areas covered so the house is never left open overnight.
- 4
Install and finish
Underlayment, flashing, vents and the new roof covering go on in that order. Before the final inspection, our crew clears the debris, runs magnets across the yard and driveway for stray nails, and goes over the finished roof with you.
What moves the cost of a replacement
Every replacement is priced from what is actually on your home. The biggest unknown on an older roof is what sits under the top layer, so we note in the estimate how deck repairs will be handled if we find more than expected once tear-off begins.
- Roof size and pitch
- More squares of roof mean more material and labor. Steep pitches need extra safety setup and slow the work.
- Material you choose
- Concrete or clay tile, architectural shingles and spray foam each cost differently to buy and install. Switching materials can also change decking or framing needs.
- Number of layers to remove
- Each extra layer adds tear-off labor and dump weight.
- Deck condition
- Rotted or delaminated sheathing is replaced by the sheet, so the amount of damage under the old roof directly affects the total.
- Penetrations and details
- Skylights, cooler curbs, chimneys, solar mounts and many valleys all need new flashing work.
Roof replacement questions
- Can you just put a new roof over the old one?
- We do not recommend it on older homes. A layover hides rotted decking and old flashing, adds weight to the framing, and leaves no clean surface for the new underlayment. A full tear-off lets us fix what is underneath.
- Can I keep my existing roof tiles?
- Sometimes. Concrete tile often outlasts the underlayment beneath it, so sound tiles can be lifted, stacked and relaid over new underlayment. We count broken or brittle pieces first and tell you whether reuse makes sense.
- What warranty comes with a new roof?
- The roofing materials carry a 30-year manufacturer warranty through the material providers. We go over which products are covered and what the terms are before the job starts.
- How long does a replacement take?
- Most homes take a few working days, depending on size, material and how much deck repair we find. Tile and foam roofs generally take longer than shingles. We give you a realistic schedule with the estimate.
- Do I need to be home or move out?
- You can stay in your home. Expect noise and some dust in the attic during tear-off. We ask you to move vehicles away from the driveway and take fragile items off walls that share the roof framing.
- Do you serve towns outside Casa Grande?
- Yes. We replace roofs in Casa Grande and nearby towns including Maricopa, Coolidge, Eloy, Arizona City and Sacaton.
