How to Tell If Your Roof Is Damaged: A Complete AZ Homeowner’s Guide

Home /  Azul Blog /  How to Tell If Your Roof Is Damaged: A Complete AZ Homeowner’s Guide

Your roof is the first line of defense against Arizona’s intense sun, monsoon storms, and desert winds. Yet, because it’s mostly out of sight, roof damage often goes unnoticed until it turns into a bigger—and much more expensive—problem. Small cracks, loose shingles, or a minor leak today can quickly lead to water intrusion, mold, and costly structural repairs if ignored.

The good news is you don’t need to be a roofing expert to spot early warning signs. An annual inspection by a licensed roofer (typically free) is always wise, but knowing what to look for inside and outside your home gives you a better chance to catch problems early and protect your roof’s long-term health.

This guide will walk you through the most important steps to identify roof damage, explain the unique stresses Arizona weather places on roofing systems, and help you decide when it’s time to repair or replace.

Outdoor Roof Inspection: What to Look For

Your first check should always be from the outside. Many warning signs are visible from the ground, but a thorough inspection usually requires roof access—something best left to a professional during an annual inspection – especially if you’re uncomfortable with ladders or heights. With that said, here are some easy things that are relatively easy to spot from the ground. 

1. Missing or Damaged Shingles and Tiles

Look for obvious gaps or irregularities. Shingles may be:

• Cracked, curled, or blistered.

• Completely missing after strong winds.

• Discolored or darker patches that may indicate UV damage, moisture intrusion or mold.

On tile roofs, check for:

• Broken or slipped tiles.

• Edge or corner cracks from flying debris.

• Gaps that expose the underlayment.

2. Flashing Around Penetrations

Metal flashing around chimneys, vents, skylights, and valleys is designed to keep water out. Bent, rusted, or missing flashing is a common source of leaks. Even a small gap can let water seep under roofing materials.

3. Gutters and Downspouts

Check your gutters after storms. If you see granules from asphalt shingles or chunks of tile, that’s a sign of accelerated wear. Gutters pulling away from the house can also signal water damage or rotted fascia boards.

4. Sagging Roof Lines

From the street, step back and look at your roofline. A sagging ridge or uneven surface can indicate structural issues below the surface. This type of damage requires immediate professional attention.

5. Underlayment Deterioration

The underlayment is the waterproof barrier beneath your shingles or tiles, and it plays a critical role in keeping moisture out of your home. Over time, Arizona’s extreme heat and UV exposure can cause it to dry, crack, or become brittle. On tile roofs, slipped or broken tiles often reveal patches of exposed underlayment—an early warning that it may already be failing. Once the underlayment breaks down, even a small rain event can allow water to penetrate your roof deck and attic.

If your roof is more than 15–20 years old, it’s wise to have the underlayment inspected, even if the visible surface looks fine.

Indoor Roof Inspection: Signs From the Inside

Not all roof damage shows up outside—sometimes the first clues appear inside your home. Unfortunately, by the time leaks become visible indoors, the problem may have been developing for some time and could be more extensive than it looks. Because water intrusion takes a while to reveal itself, an annual professional inspection is the best way to catch issues early. Still, here are the key signs to watch for inside your home

1. Ceiling Stains

Look for dark or yellowish water spots on ceilings and walls. Even small stains may indicate a slow leak. Pay close attention after heavy rains.

2. Attic Moisture

If you have an attic, inspect it with a flashlight. Signs of trouble include:

• Damp insulation.

• Water stains on rafters or sheathing.

• Mold or mildew smell.

3. Light Penetration

Turn off attic lights during the day. If you see beams of sunlight coming through the roof deck, water can get through too.

4. Sagging or Bubbling Drywall

Water-damaged drywall in ceilings or upper walls often points to roof leaks above.

Wind, Trees, and Storm Damage

Monsoon storms and high winds in Arizona are notorious for wreaking havoc on roofs. After a storm, look for these issues:

• Tree limbs or debris: Even small branches can crack tiles or lift shingles. Large fallen limbs may cause structural damage.

• Wind uplift: Strong gusts can lift shingles or tiles, breaking their seal and allowing water intrusion.

• Hail: While less frequent, hail can leave pockmarks, dents, or cracked tiles. Over time, this weakens the protective surface and leads to leaks.

• Flying debris: Patio furniture, roof tiles, or yard equipment carried by wind can cause sudden impact damage.

Trimming back trees and securing yard items before storm season is one of the simplest preventative measures homeowners can take.

Arizona-Specific Roofing Stressors

Living in the desert presents roofing challenges not seen in other regions. In addition to storm damage, Arizona roofs face year-round stressors:

1. Extreme Heat and UV Exposure

Constant sun exposure bakes roofing materials. Asphalt shingles lose granules and become brittle. Tiles can crack from thermal expansion and contraction. Underlayment dries out and deteriorates, especially on older roofs.

2. Poor Ventilation

Without adequate attic ventilation, heat builds up, cooking your roof from the inside. Poor ventilation can cause:

• Shortened roof lifespan

• Rusted fasteners

• Higher energy bills

• Mold and moisture buildup

3. Dust and Debris

Desert dust clogs gutters and drains, preventing proper water flow. Over time, this accelerates deterioration of roof edges and fascia.

4. Sudden Temperature Swings

Arizona’s monsoon season often brings sudden cooling rains after intense heat. These rapid temperature swings stress materials, especially older shingles and tiles.

Immediate Steps if You Spot Damage

If you see roof damage, acting quickly can prevent bigger problems. Here’s what to do:

1. Stay Safe

Avoid climbing onto the roof yourself—especially after rain. Use binoculars from the ground or take photos from an upstairs window.

2. Document Everything

Take photos of exterior and interior damage. This will help when filing insurance claims or working with contractors. Having ample photos to reference also minimizes the number of times you need to go up on the roof. 

3. Temporary Fixes

If water is entering the home, place buckets under leaks and cover exposed areas with a tarp if safe to do so. Seal small cracks around flashing with roofing cement until professional repairs can be made.

4. Contact Insurance

Notify your insurance company promptly. Many policies require timely reporting for storm-related damage.

5. Call a Professional Roofer

Even if the damage looks minor, only a licensed roofer can determine the full extent. Hidden problems often worsen if left unaddressed.

Repair or Replace? Making the Right Call

One of the most common questions homeowners face is whether to repair a damaged roof or replace it entirely. Here are six key factors to consider:

1. Age of Roof

• Asphalt shingles typically last 15–25 years.

• Tile roofs can last 50+ years but often require underlayment replacement sooner.

If your roof is nearing the end of its lifespan, replacement may be more cost-effective than repeated repairs. Plus, a new roof comes with a new warranty! 

2. Extent of Damage

Localized damage (a few missing shingles or cracked tiles) is usually repairable. Widespread leaks, sagging, or failing underlayment often signal the need for a full roof replacement.

3. Urgency

If damage threatens structural integrity or is causing active leaks, immediate replacement may be necessary.

4. Budget

Repairs are less expensive short-term, but a new roof may save money over the long run by preventing repeated fixes.

5. Aesthetic Concerns

Matching old materials can be difficult. Sometimes replacing the entire roof ensures a uniform appearance.

6. Long-Term Plans

If you plan to sell your home soon, a new roof can boost property value and buyer confidence. Often roof warranties can be transferred to a new owner, making your home even more marketable.

Best Time to Schedule Roof Work in Arizona

Timing matters when it comes to roof repairs and replacements.

• Spring (March–May): Pleasant weather, low humidity, materials cure well. A great time to prepare for the summer heat and Arizona monsoon season.

• Late Fall (October–December): Cooler temperatures and post-summer contractor availability make this another prime window.

• Avoid Peak Summer (June–September): Extreme heat and monsoon storms make roofing work more difficult, potentially more costly and somewhat more challenging to schedule as roofing contractors are typically busier during monsoon season.
