Monsoon storms in Phoenix and the surrounding areas produce heavy rains and extreme wind gusts that can significantly impact your roof. Local homeowners need to be prepared for these storms, which includes having a thorough checklist to ensure their roofs and properties stay protected. The professionals at Legacy Roofing have compiled the ultimate Phoenix monsoon roof checklist to help you protect your roof and home.
Why Phoenix Homeowners Should Prepare for Monsoon Season
In Arizona, the monsoon season officially runs from June 15 through September 30. The rapid shift from calm weather and extreme heat to heavy downpours, high winds, haboobs (dust storms), and microbursts can cause severe damage to property and belongings. Being proactive and preparing for monsoon season is the best way to prevent issues like roof damage, flooding, and other problems that can significantly impact your Phoenix area home. Proper Arizona monsoon roof preparation helps you avoid costly emergency repairs and water damage inside your home.
How Arizona Monsoon Storms Impact Roofing Systems
Arizona’s monsoon storms may impact your roofing system in several ways, including:
- High wind gusts and microbursts can reach over 100 miles per hour, creating pressure along the edge of your roof and causing shingles to peel, tile edges to lift, or entire sections of your roof to come off.
- During a monsoon, debris from tree branches, patio furniture, and gravel or rocks can turn into dangerous projectiles that can puncture your roofing materials and shatter roof tiles.
- Once your roof is damaged, the underlayment becomes vulnerable to heavy rain, which could infiltrate your attic and home.
- The wind-driven rain during monsoons can fall horizontally and push water underneath vents, loose shingles and tiles, and under flashed areas.
- Homes with flat roofs are vulnerable to losing gutters during dust storms, which typically occur before heavy rains that can dump debris into your drains.
- Heavy rain can add structural stress to your roof, and ponding water may degrade the roofing membrane, leading to rot or mold.
Signs Your Roof May Already Have Storm Damage
Part of proper monsoon roof damage prevention is knowing how to recognize early or existing signs of roof storm damage in Phoenix, which may include:
- Bare patches on your roof, curled shingle edges, or shingles scattered in your yard from intense, heavy rain or wind.
- Loose granules from shingles have started to accumulate inside your downspouts, gutter troughs, or on the ground directly beneath them.
- You see dents on flashing or notice loose brackets on the edges of your gutters, a common sign of storm damage caused by flying debris.
- Visible damage inside your home, such as peeling paint, wall discoloration, or bubbling drywall, is a sign of a potential roof leak caused by severe storms and water infiltration.
Inspecting Roof Tiles Before Monsoon Season
One of the best ways to prepare your roof for the monsoon season is to schedule a professional inspection at least once a year, ideally before the season starts. Legacy Roofing provides expert tile roof inspections in Phoenix to look for loose or missing tiles and signs of damage. If any of your roof tiles are cracked or missing, it can lead to a roof leak and major damage to your home, especially if you don’t catch and address the issue early. A team of roofing professionals should always perform comprehensive roof inspections, since they have the tools, knowledge, and expertise required to identify issues that most homeowners may not be able to find or identify on their own.
Checking Roof Flashing and Roof Penetrations
Roof flashing is a thin, waterproof metal barrier installed at roof intersections, joints, and penetrations such as chimneys and skylights. Flashing provides protection during heavy rain by directing water away from weak points for effective roof leak prevention in Arizona. Here are some tips to help you perform a pre-monsoonal roof flashing inspection:
- Check the metal flashing around dormers, vent pipes, chimneys, and skylights to look for rust, warping, loose pieces, or lifting edges.
- Make sure that all of the caulk and roofing cement around penetration points are secure and in good condition.
- Carefully inspect your attic for discoloration, damp insulation, or stains that may indicate a flashing leak.
- Inspect your ceilings and walls for peeling paint, water spots, or signs of mold or mildew, especially near the exterior walls.
Why Roof Underlayment Matters During Heavy Rain
Roof underlayment is a critical barrier for asphalt shingle and tile roofing systems, designed to shield your home from moisture. It’s especially important during heavy rain, when tiles or shingles act as the first line of defense, but rain that falls sideways can be forced underneath them. The underlayment serves as a key secondary waterproof barrier, keeping your insulation, roof deck, and home’s interior safe and dry during monsoon season. Ask our roofers to check the underlayment during your roof inspection in Phoenix, AZ.
How Debris and Drainage Issues Cause Roof Problems
Excess debris from storms can trap moisture and hold it against your roof’s surface, weakening materials and promoting mold, moss, and algae growth. As this debris breaks down, it begins to deteriorate vital roofing components and can even eat through metal coatings. Improper drainage can cause debris to build up in your gutters, preventing water from flowing through the downspouts and causing it to back up over the roofline. Ponding water on flat or low-slope roofs can degrade roofing membranes, while clogged drains make water pooling worse, adding more structural strain to your roof that may lead to sagging or partial collapse.
Tree Trimming Tips Before Monsoon Winds Arrive
Tree trimming is a key part of preventive roof maintenance in Phoenix, AZ, especially before monsoon winds arrive. Follow these tips as part of your roof maintenance checklist:
- Carefully trim tree canopies to decrease the chance of trees snapping or uprooting.
- Remove dead, dying, or diseased tree branches to keep them from falling onto your roof.
- Check your trees for signs of damage, including narrow, V-shaped angles between branches and crossing or rubbing branches that can create weak spots, and trim those areas as needed.
Inspecting Gutters and Roof Drainage Systems
Remember these tips to help you identify issues during a gutter and roof drainage inspection:
- Look for leaves, twigs, and other debris in your gutters that can clog downspouts.
- Make sure all of the brackets, hangers, and screws are tight and rust-free.
- Check to ensure your gutters slope gently toward the downspouts, and look for pooling water that may indicate a low spot or sag.
- Inspect all corners and seams for cracks or missing/damaged caulk.
- Flush your gutters with a hose to confirm that water is moving freely and to check for leaks at seams and fittings.
- Make sure your downspouts empty into durable splash blocks and that they are extended at least four to six feet away from your home’s foundation.
Common Roof Leak Areas During Arizona Storms
Look for these common areas where roof leaks tend to occur during Arizona storms:
- Damaged sealant on metal flashing around vents, skylights, and other penetrations.
- The roof’s valley, or the low point where two roof slopes meet, can leak after exposure to heavy, fast-moving water.
- Displaced or broken roof shingles or tiles after high wind gusts.
- Pooling water on flat roof drains and scuppers or in areas around the foundation of your home.
What Homeowners Should Do After a Monsoon Storm
Even if you follow all of these tips, you may need roof repair after a monsoon storm. Once the storm has passed, check your property for downed power lines, gas leaks, and any structural damage. Document all of the damage by taking as many photographs and videos as possible. If your roof has sustained any damage after the storm, cover it with a tarp and contact our Phoenix roof repair company to schedule service right away.
