We’ve been working on Phoenix roofs since 1984. That means we’ve torn off original gravel-and-tar built-up roofing in Garfield, probed decades-old spray foam in Encanto, and converted flat roofs to tile in Alhambra. We know the 85003, 85004, 85005, and 85006 ZIP codes - the postwar core where 1950s-1970s ranch homes dominate and flat roofing isn’t a specialty, it’s standard. Our crews are background-checked, uniformed, and equipped to handle everything from moisture-probing old foam to installing new GAF or CertainTeed systems. We don’t subcontract to storm chasers. We hire local apprentices and train them into journeymen. When you call, you get a person, not a menu.
Why Ridgeline Roofing Co. Is Phoenix’s Preferred Roof Replacement & Installation Company

Our Roof Replacement & Installation team has completed thousands of jobs across central Arizona, and our written 90-Day Done Right Promise means if something isn’t right, we make it right - no paperwork, no arguing, no runaround.
Our reviews come from neighbors. Homeowners in Coronado who watched us strip three layers of failing BUR and start fresh. Families in Maryvale who needed a flat roof that would survive another monsoon season. We answer our phones 24/7 because roof damage doesn’t wait for business hours. When a July storm dumps two inches in an hour onto a 160°F roof surface, thermal shock doesn’t schedule an appointment.

Our Roof Replacement & Installation Services in Phoenix
Full Roof Replacement
Full replacement on a Phoenix home often means confronting what previous contractors left behind. In the 85001-85010 ZIPs, we routinely find ranch homes with two, three, even four stacked layers of old felt, foam, and elastomeric coatings. That dead load adds up. Before we install anything new, we probe existing substrate with moisture meters. Trapped water in degraded SPF cannot be sealed over - it will blow the new coating off in the first monsoon. We strip to solid deck, repair what we find, and build back with proper materials. Done right. And if it’s not, we make it right.
New Construction
New builds in Phoenix face a climate unlike anywhere else in the country. Sustained 110°F ambient heat and UV index among the highest of any major U.S. city means standard 30-year asphalt shingles often fail in 15. We specify materials rated for this reality: GAF Timberline HDZ with Stainguard protection, CertainTeed Landmark Solaris reflective shingles, or Boral clay tile where the architecture supports it. For flat-roofed modern designs, we install multi-ply modified bitumen or new SPF systems with proper drainage design. We coordinate with your builder on permitting and inspection schedules - no delays, no substitutions.
Asphalt Shingles
Asphalt shingles in Phoenix are a specific calculation. On slopes below 4:12, we don’t install them at all - the extreme UV and heat cause fishmouthing and curling that voids manufacturer warranties and leaves you with a 15-year roof. On steeper pitches in neighborhoods like Central City and Encanto, we use heat-reflective formulations and proper ventilation to extend service life. We never substitute materials. What we specify is what arrives on the truck.
Metal Roofing
Metal roofing handles Phoenix’s thermal cycling better than most materials, but installation details matter enormously. Expansion and contraction from 160°F daytime surface temperatures to 70°F nights stress fasteners and seam geometry. We use concealed-fastener standing seam systems, not exposed-screw panels that back out and leak. For acreage properties and detached workshops across the Phoenix valley, metal offers durability with minimal maintenance - if it’s installed by crews who understand desert thermal dynamics.
Flat Roofing
Flat roofing is the backbone of our Phoenix work. Built-up roofing (BUR), modified bitumen, and spray polyurethane foam are niche products elsewhere - here, they’re standard. The punishment cycle is unique: months of baking heat loosen seams and fasteners, then violent monsoon cloudbursts (July-September) dump 2-3 inches in an hour onto surfaces that haven’t seen meaningful rain. Thermal shock at penetrations and edges drives our emergency call volume every August. We install multi-ply systems with proper flashing, and we never recoating over wet substrate. A square deal: the price we quote is the price you pay.
Tile Roofing
Tile roofing became dominant in Phoenix new construction by the 1990s and now appears on most remodeled homes in central neighborhoods. Clay and concrete tile handle UV and heat exceptionally well, but the switch from flat to pitched requires structural evaluation - those tiles add significant dead load. We’ve converted flat-roofed ranches to tile in Alhambra and Maryvale, engineering proper slope and drainage while preserving the low-profile aesthetic that suits these neighborhoods. We install GAF, Boral, and Owens Corning tile systems with manufacturer-certified methods.

We will be there when we say.
Common Roof Replacement & Installation Problems We See in Phoenix Homes
- Thermal shock failure at flat roof seams. Sustained 160°F surface temperatures followed by sudden monsoon downpours cause rapid contraction at seams and penetrations. We see this every August in Encanto and Coronado - flashings that were tight in June have opened by September.
- Hidden moisture in stacked SPF and BUR layers. Multiple foam applications over 40-50 years trap water that can’t evaporate in Phoenix’s dry climate because it’s sealed inside. We probe with moisture meters before any recoating. Sealing over wet foam guarantees blistering and delamination within one monsoon season.
- UV-degraded asphalt shingles on low slopes. Standard shingles installed where they shouldn’t be - slopes below 4:12 in the direct Phoenix sun - curl, fishmouth, and fail in 12-15 years. We replace these with proper low-slope membranes or re-engineer the pitch.
- Elastomeric coating chalk and crack. Phoenix’s UV cuts coating lifespan to 5-7 years without maintenance. Homeowners who skipped recoating now face substrate exposure. We strip failed coatings, address underlying damage, and specify systems with realistic maintenance intervals for this climate.

FAQs - Roof Replacement & Installation in Phoenix
No - we won’t install over stacked layers, and you shouldn’t want us to. Multiple layers of old BUR and SPF add dead load your structure wasn’t designed for, and they hide moisture damage that will destroy any new roofing from below. We probe with moisture meters, strip to solid deck, and build back properly. Call (844) 563-1816 for a free inspection - we’ll show you exactly what’s under there.
Only if the existing foam is dry and structurally sound - which it often isn’t on 40-year-old Phoenix homes. We test with calibrated moisture meters before recommending recoating. Trapped water in degraded foam cannot be sealed over; it will vaporize in summer heat and blow your new coating off. Sometimes full removal and replacement is the only honest recommendation. We don’t sell recoating to make a quick sale.
Each layer of BUR adds roughly 2-3 pounds per square foot; SPF adds 0.5-1 pound per inch of thickness. A typical Phoenix ranch with three layers of BUR plus two foam applications can carry an extra 8-12 pounds per square foot - significant load on trusses designed for far less. We assess structural capacity before specifying replacement systems. Your safety comes before our schedule.
Yes, with proper engineering. Tile adds substantial dead load - concrete tile runs 850-1,000 pounds per square - and flat-to-pitched conversion requires re-framing for slope and drainage. We’ve completed these conversions in Alhambra and Maryvale, working with structural engineers to ensure your home can handle the load while meeting Phoenix building code. The result is a roof that handles UV and heat far better, with 50+ year potential lifespan.
Our workmanship is backed by the written 90-Day Done Right Promise - if it’s not right, we make it right, no paperwork, no arguing. Manufacturer warranties vary by material: GAF and CertainTeed modified bitumen systems carry 10-20 year material warranties when installed by authorized contractors like us. SPF systems typically warranty 10-15 years with required maintenance recoating. We document every installation with photos for warranty registration. Call (844) 563-1816 to discuss which system fits your budget and how long you plan to stay in your home.
