LaredoRoofer provides metal roof repair and replacement for appropriate properties throughout the service area.
Standing-Seam Metal Roofing
Standing-seam roofs connect panels at raised seams and generally conceal the primary attachments beneath the finished surface.
The attachment system needs to keep the roof secured while also accommodating the dimensional changes that occur as metal heats and cools.
This becomes particularly important on long panels.
Exposed-Fastener Metal Roofing
Exposed-fastener systems use fasteners through the panel surface.
Those fastening points therefore remain exposed to weather and become part of the long-term maintenance inspection.
The system can perform well when designed and installed properly, but it should not be confused with standing seam simply because both roofs use metal panels.
Thermal Movement
Metal expands as it becomes warmer and contracts as it cools.
Roofing systems need to manage that movement.
Problems can develop when panels are fixed too rigidly, penetrations restrict movement or repairs prevent components from behaving as originally designed.
This is one reason repeated sealant failure on a metal roof deserves further investigation.
Metal Roof Flashing
The panel field is only one part of the roof.
Details are required at:
- walls;
- valleys;
- ridges;
- roof edges;
- penetrations;
- transitions.
These areas need to direct water away while remaining compatible with the panel system.
Metal Roof Penetrations
New penetrations should be planned carefully.
Pipes, vents, conduits, HVAC equipment and solar attachments can all affect the roof.
The penetration needs a watertight flashing method that also respects the way the surrounding metal system is intended to move.
Metal Roof Repair
Common repair areas include:
- seams;
- fasteners on applicable systems;
- penetrations;
- flashing;
- closures;
- roof edges;
- damaged panels;
- previous repairs.
The extent of the damage determines whether individual components can be repaired or a larger roof section needs replacement.
Metal Versus Shingles
Metal generally has a higher initial cost than standard asphalt shingles.
Shingles offer familiar appearance and repair methods.
Metal offers a different system design, appearance and maintenance profile.
The better option depends on the house, roof geometry, budget and owner priorities rather than one material being universally superior.
