Overflowing Eave Gutters
Dust and debris settle in long gutters, and monsoon rain backs up over the edge and under the panel ends. Gutters get cleared before the monsoon and checked after big storms.
Commercial roof repair in Whetstone for metal shops and storage buildings, where long eaves, gutters, and end laps carry most of the water.


Metal shops and storage buildings on county land around Whetstone shed every drop of rain to the eaves. On a long row of units, the gutter and the end laps above it handle more water than any other part of the roof.
When the gutter overflows or an end lap opens, water runs back under the panel and into the wall or the units below. Fixing the eave and the end laps above it ends most of those leaks.
On long metal buildings, the bottom of each panel run takes the hardest beating.
Dust and debris settle in long gutters, and monsoon rain backs up over the edge and under the panel ends. Gutters get cleared before the monsoon and checked after big storms.
Where two panels overlap along the slope, old sealant cracks and water slides through the joint into the wall line. Stains on the wall inside often line up with one lap above.
Water lingering at the eave rusts the bottom edge of each panel first. Caught early, it is brushed and primed. Edges that have thinned too far get a new panel end instead.
Screws along the eave take wind load and daily movement, and loose ones let water in right above door openings. Fasteners near doors are checked first because leaks there show fastest.
Trim along the gable ends of long metal roofs lifts in spring wind, and rain blows under it into the top of the wall. New trim screws go into solid framing rather than the old holes.
Translucent panels set into the run crack and yellow, and their laps leak into the units below during heavy storms. Panels are swapped in the same rib profile as the steel around them.
On a storage row, one bad eave can wet several units.
Sealed end laps and clear gutters keep water out of the storage units and shop bays below the eave. Renters and shop owners notice right away when the drips stop.
Treating rust at the panel ends stops holes from forming along the bottom of every run. Solid panel ends also hold their fasteners better.
Gutters and downspouts carry runoff away from doors and walls instead of along them. That protects the slab and door tracks along the eave.
Clearing gutters before monsoon season heads off the overflow leaks that show up in the first big storm. Overflow damage drops when gutters run clear all summer.
Whetstone repairs land under these two services.

Fasteners, laps, rust, and trim on the metal shops and storage buildings that make up most Whetstone roofs. Rusted eave edges get treated while the crew is on the roof.
Commercial metal roof repair
When water shows inside a unit away from the eave, tracing follows the panel run uphill to its source. Stains inside a unit are matched to the lap or screw above it.
Commercial roof leak repairAn overflowing gutter usually sends water back under the panels. Call and tell us which side of the building it happens on.
Four steps, with the eaves and gutters checked on every run.


Gutters, downspouts, end laps, eave screws, and panel ends get checked along the full length of each building, plus any skylights and vents. Bird and rodent nests in gutters are cleared as found.
Stains inside units are matched to the panel run above. On long slopes water travels down the ribs, so the trace follows the run uphill. Wall stains below the eave get traced to the lap above.
End laps get butyl tape and stitch screws, gutters are cleared and resealed, and rusted edges are brushed and primed. Downspouts are reconnected and pointed away from the doors.
A hose test runs the eave and laps while someone watches inside. Photos of each repaired run go to you. Rusted panel ends to watch are marked on the photos.
Whetstone sits north of Sierra Vista on SR 90 where SR 82 meets it. Its unit is highlighted on the map.
Rooftop units on off-post businesses, under town permits.
Historic storefronts; visible repairs wait on commission review.
Wide warehouse roofs along the rail line and I-10.
Metal barns and equipment buildings checked after hail.
Shops on SR 92 with aging skylight panels.
Two roof walks a year, before the monsoon and in fall. Each one clears dust and nesting material from gutters and downspouts, snugs loose screws, replaces cracked washers, and photographs past repairs so changes stand out.
Whetstone is unincorporated, so Cochise County Building Safety handles permits. Its minor-work exemptions leave out commercial projects, so check with the county before replacing panels or deck.
Doors sit under the eave, where gutters overflow and eave screws loosen. Water that backs up under the panel ends often shows first at the door header.
Repaired when the gutter is straight and the seams can be resealed. Rusted-through or sagging sections get replaced in matching size and color.
No. Repairs happen from the roof, and only units directly under a deck repair need the space below cleared.
Usually, yes. Long rows are worked one run at a time, and each run is closed and watertight before the crew moves on.
End laps run across the slope, so every drop from the panel above passes over them. Their sealant also takes more movement as long panels expand.
Yes. A gutter too small for a long roof run overflows in heavy rain even when clean. Larger gutters or extra downspouts fix it.
