Use this checklist from the ground, through accessible interior spaces and with a qualified roofer for roof-surface work. Arizona heat can make materials brittle, while monsoon wind and concentrated rain expose weak flashings and blocked drainage quickly.
Ground-level roof and property check
Look for:
- Missing, displaced or visibly broken roofing
- Lifted edge metal or loose trim
- Debris collecting in valleys or behind equipment
- Sagging gutters or downspouts discharging against the building
- Staining below parapets, scuppers or roof edges
- Tree branches contacting or overhanging the roof
- Pieces of tile, shingle or coating around the property
Binoculars or zoomed photos can document changes without climbing.
Drainage checklist
Water needs a clear path off every roof type.
Steep-slope roofs
- Valleys are open and free of packed debris
- Gutters and downspouts drain without overflowing
- Upper-roof discharge does not erode a lower roof surface
- Roof edges and drip details remain attached
Low-slope roofs
- Drains and scuppers are clear
- Overflow paths are not blocked
- Debris is not forming dams
- Ponding marks or repeated dirt rings are documented
- Coating or membrane around outlets remains intact
Do not push debris under shingles or into drains. The Asphalt Roofing Manufacturers Association recommends non-abrasive debris removal and keeping gutters clear for asphalt systems.
Roofing-surface checklist
Asphalt shingles
Check for missing tabs, exposed fasteners, impact damage, cracking, lifted edges and unusual granule accumulation. Do not pressure-wash or field-coat shingles without confirming manufacturer compatibility.
Tile
Look for displaced or visibly broken tile, mortar or accessory deterioration, and prior patches. Surface tile can hide underlayment and flashing conditions, so a dry-looking tile field does not prove the assembly below is healthy.
Foam and coated roofs
Look for coating erosion, cracks, exposed foam, blisters, punctures, bird damage and separation around flashings. Recoating should follow preparation and compatibility requirements for the existing system.
Membrane roofs
Check visible seams, edge securement, penetrations, walk paths, punctures and repairs. Keep sharp objects and unnecessary traffic off the membrane.
Flashings and penetrations
Give extra attention to:
- Pipe boots
- Skylights
- Chimneys
- Roof-to-wall transitions
- Valleys
- HVAC curbs
- Solar attachments
- Parapets and coping
- Scuppers and drains
A field material can remain serviceable while one transition fails.
Attic and interior checklist
Where safely accessible, note:
- New ceiling or wall stains
- Damp or compressed insulation
- Darkened or deteriorated decking
- Daylight at unintended openings
- Condensation or musty odor
- Bathroom, dryer or kitchen exhaust terminating in the attic
- Blocked soffit baffles or obvious airflow restrictions
The U.S. Department of Energy durable-attic guide identifies roof leaks, flashing defects, indoor moisture, blocked ventilation and wet insulation as conditions that can damage an attic.
After a monsoon, wind or contractor visit
Add an event-triggered check after:
- Severe wind or hail
- Debris impact
- Active interior leaking
- Solar, HVAC, antenna or pest-control work
- Tree trimming over the roof
- Exterior painting or stucco work near flashings
Document the condition before and after another trade accesses the roof.
Keep a maintenance record
A simple roof log should include:
| Record | What to save |
|---|---|
| Inspection | Date, weather, roof areas and photos |
| Maintenance | Drainage clearing and approved cleaning |
| Repair | Scope, contractor, invoice and completion photos |
| Products | Coating, membrane, tile or shingle details |
| Warranty | Certificate, registration and notice requirements |
| Roof access | Other trades and equipment work |
The NRCA homeowner resources emphasize routine inspection and maintenance and note that leaks do not automatically require full replacement.
When to schedule a professional inspection
Call when you see active leaking, displaced materials, repeated ponding, exposed foam, open membrane seams, deteriorated flashing, structural sagging or damage after a significant weather event. Also schedule an inspection before buying a property or planning rooftop equipment.
Use the companion roof maintenance schedule and recordkeeping guide to decide when to check the roof. America Roofing can document current conditions through its Arizona roof-inspection service. To get a roof-specific scope, request a free roofing estimate.

Commercial Roof Maintenance Details Disclosed
A commercial roof isn't the same as your residential roof, both in terms of features, cost, and maintenance. Maintenance of a commercial roof is a lot more challenging. Commercial roofing is, more than often, used quite roughly for many reasons. Some offices may opt to transform their rooftop into a sitting space while others may decide to use it for housing external HVAC units, water tanks, etc. However you decide to use the roof of your commercial building, you need to make sure it's maintained in top shape to ensure the safety of the staff and equipment inside the building and keep your office building looking attractive. Commercial roof maintenance can be challenging but fret not. We've disclosed some
Bi-Annual Inspection
Most offices schedule roof inspections every year. Some are even negligent and don't get their roofs inspected at all unless there's a roof-related issue. However, to keep your commercial roof looking and functioning great, follow this secret that we can swear by – get your commercial roof inspected by a roofing professional
, even if there are no signs of roof damage or roof-related problems. It would help bring any issues, even the smallest ones, in light on time, and you can get them fixed right away. This way, not only roof problems won't get an opportunity to worsen, and you'll save plenty of money that would otherwise be spent on costly repair work.
Clean Gutters and Drains Regularly
If you think your commercial building is high enough to not get leaves and other debris blocking the drains and gutters, you're mistaken. No matter how tall a building is, drains and gutters can always get blocked by debris that comes through the wind. If they aren't cleaned on a regular basis, water from rain or melting of snow will stay stagnant on the rooftop and result in costly water-related damage. Therefore, assign the task of cleaning the rooftop's drains and gutter system regularly to any of the housekeeping teams never to miss the cleaning.
Post-Storm Inspection
Make sure to get your commercial roof inspected by professionals after a storm, even if the 6 months for the scheduled inspection aren't over yet. Storms can result in serious damages that aren't visible every time. A post-storm professional roof inspection is a great way to keep your commercial roofing in the best condition for years to come.
Don't Pressure Wash
Pressure washing your commercial roof may sound like a great idea, but it really isn't. Pressure washing a commercial roof can result in water and debris seeping under the tiles, which will cause serious roof damage over time. Therefore, the next commercial roof maintenance secret is not to pressure wash your commercial roof.
Summary
Commercial roof maintenance doesn't come easy, but following the right maintenance tips can really make a difference. Hiring
to inspect your roof regularly is one of the most critical and often overlooked ways to keeping your commercial roof in top shape.

How to Master Roof Maintenance in 30 Days
| Task | Frequency |
|---|---|
| Visual inspection (ground level) | Twice a year + after storms |
| Gutter cleaning | At least twice a year |
| Debris removal from roof surface | At least twice a year |
| Tree branch trimming | As needed, at least annually |
| Attic ventilation check | Twice a year |
| Flashing and sealant inspection | Twice a year |
| Professional roof inspection | Once to twice a year |
The first step in any plan is a regular inspection. Think of it like a wellness checkup for your house. Because 31% of home inspection issues are roof-related, being proactive isn't just a "good idea"—it’s essential financial protection. In the Valley of the Sun, our roofs face unique stressors. Between the 115-degree summer days and the sudden violence of monsoon winds, your roof is your home's primary shield. Protecting that investment starts with understanding what to look for and when to act.
- Binoculars: For high-resolution views from the safety of the lawn.
- Sturdy Ladder: If you must climb, ensure it’s rated for your weight and placed on level ground.
- Leaf Blower or Soft Broom: For clearing debris without scrubbing away protective granules.
- Work Gloves: To protect your hands from sharp metal and "gutter gunk."
- Flashlight: For your Week 4 attic inspection.
- Missing or Displaced Shingles/Tiles: Look for gaps in the pattern.
- Curling or Buckling: This often indicates heat damage or the end of the material's lifespan.
- Granules in the Gutters: If your gutters look like they’re filled with coffee grounds, your asphalt shingles are losing their UV protection.
- Damaged Flashing: Look for rusted or bent metal around chimneys and vents.
- Water Stains: Check the undersides of your eaves (soffits) for discoloration.
When gutters clog, water backs up. In Arizona, this leads to "wicking," where water travels upward into your roof deck, causing rot. Use a small garden trowel or your gloved hands to scoop out debris. Once the channels are clear, run a hose to ensure the downspouts are flowing freely. If water pools at the base of your home, you might need downspout extensions to protect your foundation.
If you have shade trees, you might notice moss and algae growth. While algae (those dark streaks) is mostly cosmetic, moss is a menace. It holds water and can actually lift shingles. You can treat this with a 50/50 mix of water and bleach, but never use a power washer—the high pressure will destroy your roof's integrity. For long-term prevention, consider installing zinc or copper strips near the roof peak; when it rains, the metallic ions wash down and kill biological growth.
In Phoenix, attic temperatures can soar above 150 degrees. Without proper ventilation, that heat bakes your shingles from the inside out and can even cause your roof deck to warp. Go into your attic with a flashlight. Do you see light through the vents? You should. Are the vents blocked by insulation? Clear them out.
- Concrete Tile: This is the "Gold Standard" for the Phoenix metro. While the tiles themselves can last 50 years, the underlayment (the waterproof layer beneath) usually lasts 20-25. Maintenance involves checking for cracked tiles—especially after a hailstorm—and ensuring the "bird stops" at the eave ends are intact to prevent pests from nesting.
- Asphalt Shingles: These are prone to UV degradation. Look for "balding" spots where granules are missing. If you see shingles that look shiny or black, the asphalt is exposed and will soon fail.
- Metal Roofing: Generally low maintenance, but you must check for "bimetallic corrosion." This happens if different metals touch (like a copper pipe touching a steel roof), leading to rapid rusting.
- Flat Roofs (Foam/TPO): Common in Scottsdale and Tempe. These require monthly checks for "ponding" water. If water sits for more than 48 hours after a rain, your drainage is blocked, and the weight could cause structural damage.

Prepare Your Commercial Roof For Winter In Arizona
The roof of your building keeps out cold and heat and safeguards your building against extreme weather conditions. Having a
like preparing your commercial building for the cold or ice, can help greatly in keeping your roof safe in the winter season. Some roofs are not that strong or permanent, and they may require repair or replacement within a few short years. If the winter season is still a few days away, then you still have time to look after clogged drains, scuppers, and other issues to keep your roof prepared against the extremities of the season. A qualified

Risk Increases with Cold Temperatures
Failure to correct defects and forgetting to winter proof your home before the beginning of the winter season can invite disastrous results. If your roof is toward the end of its serviceable life, but you still want it to be able to resist strong winds and severe weather conditions, then you need to invest in proper roof repairs and maintenance.

Cold temperatures and ice that accumulates on your roof can cause it to crack and break down. In northern Arizona, please protect your roof with a proactive winter roofing. A pile of fresh, towering snow can exert nearly 20 lbs. of weight per cubic foot on your roof. On a similar note, wet snow or partially melted and refrozen snow applies roughly 60 lbs. per cubic foot of weight. If you live in Northern Arizona, your roof may have been structured to bear some extra snow load, but the most excellent practice is to have heavy snow removed as soon as possible. Hire a

Roofing Maintenance Checklist: Access the Way to a Long-Lasting Roof
A schedule should combine three triggers: routine, event-driven and condition-driven. Calendar reminders matter, but a roof should not wait for the next reminder after a monsoon, fallen branch or active ceiling stain.
Routine owner observation
From the ground and inside the building, make a simple observation at least a couple of times per year and around seasonal changes. The National Roofing Contractors Association notes that periodic inspections can reveal missing or damaged materials, deteriorated flashings and interior warning signs before a serious leak is discovered.
- Roof age and system
- Prior leaks or repairs
- Warranty requirements
- Tree and debris exposure
- Rooftop equipment and foot traffic
- Drainage complexity
- Known coating or maintenance cycles
- Building use and consequence of interruption
- Strong wind, hail or debris impact
- Heavy rain paired with interior staining
- A tree limb contacts the roof
- Solar, HVAC, satellite or other rooftop work
- Pest-control or exterior trades access the roof
- A drain, scupper or gutter overflows
- A tile, shingle or piece of coating is found on the ground
- Open seams or lifted edges
- Missing or displaced materials
- Exposed foam or reinforcing fabric
- Cracked pipe boots or sealant joints
- Repeated ponding marks
- Blocked drainage
- New attic moisture
- Sagging or soft areas

Taking Care of your Roof as a New Homeowner
Being a new homeowner is equal parts exciting and daunting as it brings a bevy of responsibilities that must be taken care of diligently; otherwise, the property may develop issues atypically early on. From paying the utilities to cleaning the house, there is a lot that goes into property maintenance. But out of all the responsibilities that owning an estate dumps on a person, only a few are prioritized, such as paying the bills because otherwise, the supply will be cut. This means that the tasks that don't present an undesirable consequence right away fall by the wayside and are rarely looked after, and roof maintenance is, unfortunately, one of them. The roof of a home is an integral part of the entire structure, and if it is not maintained right, it can wreak havoc leading to severe accidents. As the famous saying goes, out of sight, out of mind, looking after a roof slips out of most new homeowners' minds because they don't see signs of damage until it's too late. That is, to spot any lingering issues, a newbie property owner needs to examine the roof up close, which they rarely do and thus forget about to follow even the most basic roof upkeep protocols. Resultantly, the roof gives out, developing leaks and holes. To avoid such roof troubles, a house owner should maintain a preventative maintenance checklist like the one below.
Regular Inspections
The internet or aged homeowners would tell you to get your roof inspected once or twice a year, but as a new property owner, you should do it much more often. And you don't need to hire professionals every time you want to inspect a roof, fetch your binoculars and scan your roof from the ground. Doing so will give enough idea about the state of your home's roofing. Contact a professional roofer if you spot any of the following issues.
- Missing or damaged shingles
- Curled or buckled shingles
- Rust spots
- Big patches of algae or moss
- Peeling paint
- Cracked caulking
- Bare spots on asphalt shingles
Keeping The Gutters Clean
Clogged gutters can significantly damage a roof without coming into notice before it is too late. Therefore, you must regularly check your channels for clogs and clean them if you find any blockages. If you don't keep the gutters clean, they might collect water, develop leaks, and eventually damage the roof.
Trimming The Surrounding Trees
Swaying lush trees around the house look absolutely breathtaking, especially during the rainy season. But they can be unimaginably dangerous for the roof. The loose limbs of a tree can fall off on the roof and damage it, or they can clog gutters and lead to leaks. Therefore, you must trim the loose foliage around your home's roofing to avoid any damage to it.
Replace Broken Or Missing Shingles
Damaged or missing shingles can accumulate moisture and cause the roof to rot or develop moss/lichen. So, you should always keep an eye out for the shingles covering your roof. Enjoy a wholesome home-owning experience by maintaining your property and its roof right! And be sure to
