Shingle Roofing in Casa Grande
We install asphalt shingle roofs on homes of every age, and we pay close attention to the older ones. We strip the old layers, fix the deck underneath, replace tired flashing and pipe boots, then lay shingles to the manufacturer's nailing and ventilation specs.
When a Shingle Roof Is the Right Choice
Asphalt shingles are a good fit for pitched roofs on homes built for them: lighter than tile, quicker to install and easy to repair one course at a time. Architectural shingles, with their laminated double layer, hold up to heat and wind better than the flat 3-tab shingles found on many roofs from past decades.
Older homes add a few complications. We often find two layers of shingles stacked on each other, plank decking with gaps between boards, roof cement smeared over flashing instead of replacing it, and pipe boots cracked by years of UV. A new shingle roof only performs as well as what sits under it, so we deal with those parts before anything new goes on.
If your roof is tile, foam or low-slope, our Tile Roofing, Foam Roofing and Flat Roofing pages cover those systems.
What Our Shingle Work Includes
Full tear-off to the deck
Every old layer comes off instead of getting covered. Stacked layers add weight, hold heat and hide soft decking, and many manufacturers restrict coverage on shingles installed over another roof.
Decking repair
Delaminated plywood, water-stained OSB and split planks get replaced. Where an older plank deck has wide gaps between boards, we add sheathing so nails grip and shingles sit flat.
High-temperature underlayment
We roll a heat-rated synthetic underlayment across the entire deck. Valleys and the areas around pipes and vents, where water concentrates, get an added layer of peel-and-stick membrane.
New flashing, drip edge and pipe boots
Step flashing along walls, valley metal, eave drip edge and new pipe boots replace the old parts. Rubber boots tend to crack first under strong sun, so we never put old ones back.
Attic airflow that works
Cool air needs a way in low on the roof and hot air needs a way out near the peak, so we size soffit and ridge or roof vents to work as a pair. Trapped attic heat cooks shingles from the underside and cuts years off their life.
Manufacturer-backed shingles
The shingle lines we install come with a 30-year manufacturer warranty through roofing material providers. Following their installation specs is what keeps that coverage in force.
Signs Your Shingles Need Attention
Granules in the downspouts or yard
Granules shield the asphalt from UV. Once they wash off, the mat underneath dries out and cracks quickly.
Curling or cupped edges
Shingles that lift at the corners or sag in the middle have lost their flexibility, often from attic heat or age.
Cracked or brittle tabs
Aged 3-tab shingles snap when bent. Those that crack in place no longer shed water across the seams.
Patches that don't match
Different colors or shingle styles in one area mean earlier repairs. They're worth checking for nails left exposed or cement used in place of flashing.
Stains on the ceiling or attic wood
Brown rings around a vent pipe or chimney usually point to a split pipe boot or failed flashing, not the shingles themselves.
How a Shingle Job Runs
- 1
We look at the roof and the attic
We walk the roof, check the decking from the attic and photograph what we find, including any earlier repairs. You see the photos, not just our summary.
- 2
Written line-item estimate
Each piece is listed: tear-off, layers, decking allowance, underlayment, flashing, vents and shingles. If decking is uncertain until tear-off, we say so up front and explain how it's priced.
- 3
Permit and material delivery
We pull the permit with the city or county and schedule delivery so bundles aren't left baking on the driveway for days.
- 4
Tear-off and install
We cover landscaping and siding, strip the old roof, fix the deck, then install underlayment, flashing, shingles and ridge cap. Most homes are dried in by the end of the first day.
- 5
Cleanup and final review
We run a magnetic sweeper for nails, haul off the debris and go over the finished roof with you.
What Moves the Price of a Shingle Roof
Shingle cost depends far more on the roof than on the shingle. Two homes of the same size can price very differently once layers, decking and roof shape are counted. We list each item separately so you can see where the money goes.
- Roof size and pitch
- More squares mean more material and labor. Steep pitches need extra safety setup and move slower.
- Number of existing layers
- Each layer adds tear-off labor and disposal weight. Homes that have been reroofed before often have two.
- Decking condition
- Soft, delaminated or gapped decking has to be replaced or overlaid. This is the most common surprise on older roofs, so we explain it in writing before work starts.
- Shingle line and accessories
- Architectural shingles cost more than 3-tab and last longer. Ridge vents, new pipe boots and valley metal add to the total.
- Penetrations and roof shape
- Chimneys, skylights, dormers and many valleys require more flashing and hand work.
Common Questions About Shingle Roofs
Something not covered here? (520) 492-6369
Can you put new shingles over my old ones to save money?
Skipping the tear-off lowers the first bill, but we don't roof over an existing layer. That second layer hides soft or rotted decking, traps heat against the new shingles and may limit what the manufacturer will cover. Taking the roof down to the wood is the only way to see its real condition and fix it.
How long do asphalt shingles last here?
Sun and heat wear shingles down faster than cold does. Shingle grade, attic ventilation and which way each slope faces all play a part, and slopes facing south and west usually show wear first. Architectural shingles over a well-vented attic outlast 3-tab by a clear margin.
Should I repair my shingles or replace the roof?
A cracked pipe boot or a handful of missing shingles is usually a repair job, covered on our Roof Repair page. Granule loss across whole slopes, tabs that snap when lifted or leaks in several places usually point to replacement, which our Roof Replacement page explains. We'll give you a straight answer on which one fits your roof.
What happens if the decking is rotten?
We pause, take photos and walk you through what we found before any wood is replaced. Your written estimate already spells out how decking is priced, so the cost of that work isn't a mystery.
What warranty comes with the shingles?
The shingles we install carry a 30-year manufacturer warranty through roofing material providers. Because that coverage depends on correct installation, we follow the manufacturer's specs for nailing, underlayment and ventilation.
Do you work outside Casa Grande?
Yes. We install shingle roofs in Maricopa, Coolidge, Eloy, Arizona City and Sacaton as well.
