Fit Check
Is Your Building Ready For A Metal Roof?
Metal works on sloped roofs and on flat roofs converted with retrofit framing. Check these points first.
Good Fit
- Sloped roof with straight purlins and framing
- Existing panels with rust only at the surface
- Flat roof the owner wants converted to slope
- A building you plan to keep for decades
- Roof that sheds water to gutters or edges
Fix First Or Choose Another System
- Rust that has eaten through panel laps
- Purlins or framing bent from past loads
- Retrofit plans that need an engineer
- Gutters too small for monsoon downpours
- Mixed panel profiles patched over the years
Metal Problems
Common Leak Points On Metal Roofs
Desert heat moves metal panels every day. These five spots show it first.
Drips under exposed screws
Likely Cause
Fasteners backed out by daily expansion, with washers that dried and cracked.
What We Do
Replace with oversized fasteners and new washers, and check the purlin bite at each one.
Leaks along panel side laps
Likely Cause
Lap sealant or butyl tape that hardened and lost its seal.
What We Do
Open the lap, clean it, install new butyl, and refasten through the lap.
Rust at panel ends and laps
Likely Cause
Factory finish worn thin where water sits at end laps and gutters.
What We Do
Wire-brush and prime the rust, replace perforated panels, and seal the end laps.
Leaks around rooftop units
Likely Cause
Flat curb flashings on a sloped metal roof that dam water on the high side.
What We Do
Install a properly sized curb with a diverter on the high side so water runs around it.
Overflowing gutters in monsoon rain
Likely Cause
Gutters and downspouts too small, or packed with dust and debris.
What We Do
Clear and reseal the gutters, and size larger gutters or added downspouts where the roof area calls for it.
Metal Options
Commercial Metal Roof Work For Tolleson Buildings
Three kinds of metal roof work, matched to what the panels and framing show.
Retrofit Framing Over A Flat Roof
Framing is fastened through the old roof into the structure, creating slope for new metal panels without a tear-off.
Edge, Gutter, And Trim
Gutters, rake trim, and coping get resized or replaced so monsoon downpours leave the roof instead of backing up.

Check your panels and framing against both columns.

| Fasteners | Some backed out | Loose across the roof |
| Panel shape | Flat and straight | Bent, dented, or mixed profiles |
| Framing | Purlins straight and tight | Framing damage that needs repair |
| Leaks | A few laps or curbs | Many laps and penetrations |
| Roof age | Well short of 40 years | Past its service life |

Metal Process
How A Metal Roof Job Runs
From the first fastener check to the last trim piece, the work follows five steps.
Step 1: Inspect Your Roof
We check fasteners, laps, panel ends, gutters, and the framing underneath, and core any flat roof slated for a retrofit to see what sits under it.
Step 2: Choose Repair Or Panels
Surface rust and loose screws point to refastening and resealing, while perforated panels and bent framing point to new panels or a retrofit.
Step 3: Prepare The Structure
Damaged purlins get repaired, and on a retrofit, framing is laid out and fastened through the old roof into the building structure.
Step 4: Install Panels And Trim
Panels go on with clips or fasteners matched to the profile, followed by ridge, rake, gutter, and curb trim sealed at every lap.
Step 5: Water Check And Photos
Gutters are flushed, laps and curbs get a water check, and you receive photos and notes on fastener and sealant upkeep.

Questions For A Tolleson Commercial Metal Roofing Contractor
Can you install or repair commercial metal roofs around Tolleson?
Yes. We work on standing-seam and through-fastened metal on shop buildings, older ag-related structures, and newer pre-engineered warehouses. The usual desert problems are backed-out fasteners, failed lap sealant, and rust where coatings wore off, and the fix ranges from refastening and resealing to a coating system, new panels, or retrofit framing over a leaking flat roof.
How long does a metal roof last here?
Forty years or more is a common range with good installation and upkeep. Fastener checks, sealant renewal at laps, and rust treatment at panel ends keep a metal roof on the long end of that range.
What is a metal roof retrofit?
Light-gauge framing is fastened through an old flat roof into the structure, then new metal panels go over it with built-in slope. The old roof stays in place, and an engineer confirms the framing and loads where the scope requires it.
Should exposed fasteners be replaced or just tightened?
Replaced, in most cases. A backed-out screw has usually enlarged its hole, so an oversized fastener with a new washer seals better than retightening the old one.
Can metal roofs be coated?
A coating system is one option for metal with surface rust and tight laps. Fasteners and laps get repaired first, rust gets primed, and the coating goes over that prepared surface.
Can solar go on a metal roof?
It can. Standing-seam roofs take clamps that grip the seams without holes, and through-fastened panels take brackets screwed into the purlins with sealed bases. Fasteners and laps under the array get checked first, since they are harder to reach once panels are on.
Does a metal roof make the building hotter?
Bare metal in full sun gets hot. A light finish, insulation under the panels, and ventilation where the building allows all cut the heat that reaches the space below.
