Purlins
Steel framing under a leaking screw stays free of the rust that weakens connections over time.

Panels expand in the afternoon heat and shrink overnight. We repair what that movement loosens on Scottsdale metal buildings: fasteners, laps, rust spots, and skylights.

Repair Now Or Plan A New Metal Roof?
Metal roofs take repairs well while the panels themselves are solid. Rust-through and widespread panel damage change the answer.
A Repair Covers It When
- Leaks come from fasteners, laps, or skylights
- Rust stays on the surface and brushes clean
- Panels sit flat with no buckling at the laps
- Trim and ridge caps are still attached
- The underside shows no daylight through the panels
Plan Replacement When
- Rust has eaten holes through several panels
- Panel laps leak in many places at once
- Insulation under the panels is wet across the building
- Repeated screw replacement has enlarged the holes
- Panels have pulled loose along the eave
What You See On A Metal Roof, And Why
Metal roof leaks follow the parts that move or corrode: fasteners, laps, cut edges, and the panels around skylights.
What You See
Drips along a panel run
Likely Cause
Screws backed out by daily expansion, with rubber washers worn flat or split.
What We Do
Pull the loose screws and install larger-diameter fasteners with new washers in the same holes.
What You See
Water at a panel lap
Likely Cause
Sealant in the side or end lap that dried out and opened as the panels moved.
What We Do
Separate and clean the lap, then reseal it with butyl tape or sealant suited to the panel.
What You See
Orange streaks below screws
Likely Cause
Rust bloom starting at cut edges and around fastener heads where the paint wore off.
What We Do
Wire-brush the rust to clean metal and prime it before the bloom spreads under the paint.
What You See
Light and drips at a skylight
Likely Cause
Plastic skylight panels yellowed and cracked by years of sun.
What We Do
Swap the cracked panel for a matching profile or cover it, then reseal the laps on both sides.
What You See
Leaks around a roof curb
Likely Cause
Flashing around a curb or vent that was cut into the panels and sealed only with caulk.
What We Do
Rebuild the curb flashing with a cricket on the upslope side so water flows around the opening.
Commercial Metal Roof Repair Options In Scottsdale
Each repair targets one moving or corroding part of the panel system.
| Repair | What It Fixes | When It Is Enough |
|---|---|---|
| Fastener replacement | Backed-out screws and worn washers | The holes still grip a larger screw |
| Lap reseal | Opened side and end laps | Panels at the lap still sit flat |
| Rust treatment | Surface rust at cut edges and screws | The metal under the rust is still solid |
| Skylight panel swap | Yellowed or cracked plastic panels | The skylight frame and curb are intact |
| Curb reflashing | Leaks at units and vents cut into panels | The opening is framed and level |
What A Timely Metal Roof Repair Keeps Dry
A metal roof leak that keeps dripping reaches more than the floor below.
Insulation Blanket
Faced insulation under the panels stays dry instead of sagging and dripping long after the rain stops.
Panel Paint
Primed rust spots stop spreading under the paint, which keeps the rest of the panel from flaking.
Stock And Equipment
Inventory and machines on the shop floor stay out of the drip line under the panel laps.
Drips Under The Metal After A Hot Day?
Call and describe where the drips land. Fastener and lap leaks often show up after heat rather than rain, and that pattern helps us find them.
(623) 310-0118How A Metal Roof Repair Runs
Work moves along the panel runs, one row of fasteners and one lap at a time.
Step 1: Inspect Your Roof
We walk the panel runs, check fastener heads and washers, lift lap edges, and look for rust bloom at cut edges and around skylights.
Step 2: Find The Entry Point
Drips inside get matched to the panel above them. Loose screws, open laps, or a curb with cracked caulk in that line get marked for repair.
Step 3: Seal Or Rebuild The Detail
Materials come up in the order they are used: larger fasteners and washers first, then butyl tape and sealant for the laps, then primer for rust.
Step 4: Hose Test And Photo Record
Water is run over the repaired laps and skylights, and the photo record shows each fastener row and lap we touched.

Metal Roof Repair Questions
What Causes Leaks On A Metal Roof In Scottsdale?
Movement and corrosion. Afternoon heat expands the panels and cool nights shrink them, and that daily cycle loosens screws and works laps open. Rust then starts at cut edges and screw heads. Common repairs are larger fasteners, resealed laps, primed rust spots, and new skylight panels.
Why Use Larger Screws Instead Of The Same Size?
Because the old holes have widened. A screw that backed out has worn its hole in the panel and purlin, so a larger diameter grips fresh metal and seals with its new washer.
Can Rusted Panels Be Repaired?
Surface rust can. Wire-brushing to clean metal and priming stops the bloom. Panels with holes rusted through get a patch panel or a replacement section, and widespread rust-through points toward a new roof.
Is A Coating Part Of Metal Roof Repair?
Sometimes, over primed rust spots and resealed laps where the owner wants extra protection. Repairs come first, because coating over loose fasteners or open laps traps the problem underneath.
Do North Scottsdale Rules Affect Metal Roof Repairs?
They can on visible roofs. The City guide for Environmentally Sensitive Lands discourages mirror-like materials, so shiny new flashing or bright panels on a roof seen from the street get checked with the City first.
Can Skylight Panels Be Replaced On Their Own?
Yes. Plastic skylight panels come in matching profiles, so a yellowed or cracked panel comes out and a new one goes in with fresh fasteners and sealed laps on both sides.
