Roof Symptoms
Hammond Commercial Metal Roofing Problems We Replace
Metal roofs leak at fasteners, laps, and edges long before the steel wears through.
Drips In Rows Along Purlins
Inside The Building
Water lands in straight lines across the floor, matching the screw rows above.
On The Roof
Backed-out screws and cracked washers worked loose by heat and freeze-thaw.
Rust At Panel Ends
Inside The Building
Orange streaks run down the inside of the eave wall below the roof edge.
On The Roof
Rust along end laps and eaves where water and debris sit against cut steel.
Gutter Damage After Snow Slides
Inside The Building
Bent gutters and dented equipment show up along one side each spring.
On The Roof
Snow sheeting off smooth panels with no snow guards above doors or units.
Leaks Where Roof Meets Wall
Inside The Building
Stains form high on walls where a metal roof butts a taller building.
On The Roof
Failed wall flashing and loose trim at the joint between roof and wall.
Skylight Panels Cracking
Inside The Building
Light comes through, but so do drips under the clear panels along the ridge.
On The Roof
Brittle, cracked skylight panels and loose closures where they meet the steel.
Choices On This Roof
Commercial Metal Roofing Decisions For Hammond Buildings
Four questions shape each metal roof we install, answered from the building plans and the roof visit.
Snow Load On Commercial Metal Roofs
Design loads are checked with the building engineer or plans, and snow guards go where sliding snow could hit people, cars, or units.
Metal Roof Retrofit Framing
A light-gauge steel subframe over a flat roof adds slope and room for insulation, after an engineer confirms the structure carries it.
Standing Seam Vs Exposed Fastener Metal Roofs
Hidden-clip standing seam suits long service with little upkeep; screw-down panels cost less and need washer checks over time.
Trim And Wall Flashing
Eave, rake, ridge, and wall flashings are sized to the panel profile so the joints stay closed as the steel moves.
What Changes
What New Commercial Metal Roofing Means For Hammond Shops
A new metal roof changes the parts that leaked on the old one: screws, laps, and edges.
Fasteners Out Of The Weather
Standing-seam clips sit under raised seams, so the screw holes that leak on older panel roofs are covered and out of the path of running water.
Room To Move With Temperature
Panels slide on their clips as the steel heats and cools, which keeps seams tight through the daily swings of a northwest Indiana spring.
Slope Where Water Used To Sit
Retrofit framing over a flat roof sends rain and meltwater to gutters instead of letting it pond, and adds space for thicker insulation underneath.
Snow Held Above Doors
Snow guards set over entries, gutters, and units keep sheets of snow from sliding onto people and equipment during a thaw.
Screws Backing Out Of Your Shop Roof?
Have the panels, laps, and trim checked, and get a price on repair or new steel.
How The Work Runs
How Hammond Commercial Metal Roofing Is Installed
Metal roofs go on from the eave up, with each run closed before the crew leaves for the day.
Measure Panels And Check Loads
Panel runs, slope, and trim are measured, and the snow design load is confirmed from plans or the building engineer.
Prepare Deck Or Framing
Old panels come off or retrofit framing goes up over the flat roof, with insulation set between the members.
Set Panels From The Eave
Panels are clipped or fastened in runs from the eave, and seams are closed as each run goes down.
Trim, Guard, And Walk
Ridge, rake, and wall flashings are installed, snow guards set, and the roof walked with you at the end.

Commercial Metal Roofing Questions In Hammond
How does snow load affect commercial metal roofs in Hammond?
Weight plus sliding snow
Snow adds weight the framing must carry, and drifts stack against parapets and higher walls. Metal also sheds snow all at once, which damages gutters and lower roofs. Loads are checked against the plans, and snow guards go where sliding snow could hurt someone.
What is metal roof retrofit framing on a Hammond commercial building?
A sloped subframe
A light-gauge steel subframe built over the existing roof so new metal can go on without full tear-off. It adds slope to a flat roof and room for insulation. An engineer confirms the building can carry the framing and panels.
What are the biggest problems with commercial metal roofs in Hammond?
Fasteners, laps, rust
Loose or leaking screws, open seams and laps, rust at panel edges, and failed flashing at walls and penetrations top the list. Heat and freeze-thaw work fasteners loose over the years. Failed parts are repaired, and badly rusted panels are replaced.
Should a Hammond building use standing seam or exposed-fastener metal roofing?
Standing seam for long service
Standing seam hides fasteners under raised seams and lets panels move, so it leaks less over time. Exposed-fastener panels cost less up front but rely on washered screws that need checking and replacing. For long service with little upkeep, standing seam usually wins.
Can a metal roof go over an existing flat roof?
Yes, with retrofit framing
Yes. Retrofit framing sits on the existing roof and carries new panels at a pitch that sheds water. The old roof stays as a base, which avoids tear-off, as long as the structure checks out for the added weight.
How often should screws on a metal roof be checked?
Every few years
Exposed-fastener roofs need a screw and washer check every few years and after major storms. Loose screws are tightened or upsized, cracked washers replaced, and laps resealed before small drips turn into rusted purlins.
