Drips Along The Screw Lines
Washers dry out and crack, screws back out, and water runs down each shank into the purlin and onto equipment below.

As a Decatur commercial roof repair contractor, we replace leaking screws, reseal laps, and swap rusted panels on metal shops, storage buildings, and farm buildings.
Decatur commercial roof repair work runs heavy on steel: shops, equipment buildings, and storage halls with exposed-fastener roofs.
Ribbed steel roofs on shops and farm buildings leak in predictable places. Screws back out, washers crack, laps at panel ends lift, and rust starts where water sits at the eave and gutter line. Skylight panels and wall trim add a few more.
We walk the roof bay by bay, look underneath for rust streaks and daylight, and fix each spot with matching parts.

Steel roofs here give out in a handful of places.
Washers dry out and crack, screws back out, and water runs down each shank into the purlin and onto equipment below.
Panel ends hold water and road dust, so rust starts at the bottom edge and works up long before the middle shows wear.
Fiberglass skylight panels in a steel roof turn brittle and crack, and their laps leak where they meet the steel.
Equipment lean-tos tied into the main building leak at the joint flashing, where two roofs meet at different slopes.
Gutters on steel buildings hold leaves and grain dust, stay wet, and rust through along the seams first.
Dry steel roofs protect equipment, feed, and stored stock.
Replacing a few rusted panels keeps the rest of a sound roof working for years of use.
Stopping drips at the screw line keeps water off machinery, feed, and stored stock below.
Each repair note explains what failed, so owners know which bays to check after the next storm.
Repairs for exposed-fastener steel roofs.
Old screws come out, larger ones with new washers go in, and each one lands in the purlin below.
Panels rusted through at the eave get replaced with the same profile and gauge, then lapped and sealed.
Opened laps get cleaned, new butyl tape goes in, and stitch screws pull them tight.
Cracked skylight panels get replaced and the joint where lean-tos meet the main roof gets new flashing.
Call with the building and bay. Loose screws and laps get sealed first.

Bay by bay, the walk covers screw lines, end laps, eaves, skylights, and wall trim, then a look underneath for daylight and rust streaks along the purlins.
Loose screws on solid steel get replaced. Lifted laps get resealed. Panels rusted through or soft underfoot get cut out and replaced.
Surface rust on solid panels gets cleaned and treated. Rust through laps and panel ends past sealing goes on the replacement list.
New screws go in a size up, laps get butyl and stitch screws, and every new panel gets checked against the purlin line.
The record lists each bay repaired and the spots to check after storms, so small leaks get caught early next time.
Wind-driven rain is the real test for steel laps and screw lines. If a drip returns, the follow-up starts at the repaired bay and checks the laps uphill of it.

Steel roofs, price, and getting a roofer out.
Metal roofs on commercial buildings, shops, and storage buildings in Decatur make up much of our work there: screws, laps, rusted panels, and flashing at walls, curbs, and skylights. Each repair note explains what caused the problem.
A screw line costs far less than a row of rusted panels. Price depends on how many screws, laps, or panels need work, how high the roof is, and access around equipment. The free estimate counts it all and puts it in writing.
Decatur is part of our regular area, and steel farm buildings, equipment sheds, and shops get the same walk, written scope, and record as any commercial roof.
Ask whether they replace screws a size up, check that each one hits the purlin, and match panel profile and gauge on swaps. Ask for the repair in writing before work starts so you can compare.
Yes. Cracked skylight panels come out and new ones in the same rib profile go in, with fresh sealant at the laps where they meet the steel.
Rusted gutter sections get cut out and replaced, and the eave trim above them gets checked, since gutters that hold water rust panel ends too.
Dust and chaff collect at laps and gutters, hold moisture, and speed up rust. Clearing it during a repair visit helps the new sealant and screws last.
The joint flashing between the two roofs gets replaced and lapped under the upper roof panels, so water from the steeper main roof runs over it instead of behind it.
Tell us which bay drips and how old the steel is. We find the screw, lap, or panel and fix it.
