Christian Jordan quoted our roof and the finished tin roof looks amazing.

Cierra B.

Christian Jordan came out to quote our home for a roof replacement, and didn't hesitate to walk around on our 26 year old roof. Unfortunately, my credit score prevented me from being able to have the roof replaced, but Christian went ahead and put a tarp on the leaking side at no cost. Hopefully in the future, I'll be better off financially, and will be able to call Christian to come back out for the replacement. Excellent service!! Very polite, quick, and helpful.

Elizabeth A.

Very satisfied with the quote appointment! I was given a text with live updates to the technicians arrival time and a phone call 30 min before arrival. Technician spent an hour going over the whole roof and in the attic to diagnose the leak. He gave a detailed explanation of what was wrong and how to fix it and answered all the questions I had. I look forward to getting the quote by email! Thank you!

Energy Efficiency Benefits

Reflectivity and Cool Roof Principles

Metal roofing’s high solar reflectance index (SRI) sends a significant portion of radiant heat back into the atmosphere. Light-colored coatings commonly reach SRI values above 70, translating into cooler attic temperatures, reduced HVAC cycling, and lower electricity usage during Tennessee summers.

Insulation Synergy

Raised batten systems create thermal breaks between metal skin and decking
R-value upgrades are achieved by pairing rigid foam boards under panels
Radiant barriers in attics complement the metal’s inherent emissivity

Seasonal Performance in Corryton

Winter sunlight absorbed by darker metal colors adds passive warming, while rapid snow melt reduces ice dam formation. During shoulder seasons, stable roof deck temperatures minimize expansion-contraction stress on framing members.

Durability and Longevity

Resistance to Wind, Hail, Fire

Tested to UL 2218 Class 4 for hail impact
UL 790 Class A fire rating when installed over non-combustible underlayment
ASTM E1592 wind uplift compliance through continuous clip attachment

Corrosion Protection Technologies

Galvalume steel combines aluminum, zinc, and silicon alloy for sacrificial protection
PVDF (polyvinylidene fluoride) coatings resist chalking, fading, and acid rain
Factory-applied strippable film on panels prevents scratching during handling

Warranty Coverage Themes

Material warranties often span 40 to 50 years on substrate integrity
Finish warranties protect against excessive fade, chalk, or peel
HEP workmanship assurances back flashing integrity and water-tightness for extended terms

Architectural Versatility

Color Palettes and Coatings

Matte, metallic, and textured finishes expand design freedom
Cool pigment technology enables darker colors with high reflectivity
Custom color matching for historical districts or HOA requirements

Profiles for Different Home Styles

Board-and-batten farmhouse designs pair well with 16-inch standing seam ribs
Craftsman bungalows gain depth from diamond or scallop metal shingles
Contemporary builds highlight low-profile snap-lock panels for clean lines

Compatibility with Add-Ons

Pre-punched mounting rails simplify solar panel attachment without penetrating panels
Half-round or box gutters integrate into roof edge cleats to maintain drainage efficiency
Curb-mounted skylights receive factory flashing kits matched to panel profile

Environmental Sustainability

Recycled Content

Steel and aluminum roofing frequently contain 25–35 % post-consumer recycled material, reducing reliance on virgin ore extraction and supporting circular manufacturing loops.

End-of-Life Recycling

At the end of its service life, metal roofing can be 100 % recycled into new coils or structural shapes. This contrasts with asphalt shingles that often head to construction waste landfills.

Stormwater Runoff Quality

Smooth metal surfaces minimize organic residue, leading to cleaner runoff that can be harvested in rain barrels or cisterns for landscape irrigation in Corryton gardens.

Maintenance Guidelines

Scheduled Inspections

Semi-annual visual checks at spring and fall for sealant integrity and fastener security
Post-storm walk-arounds to locate potential impact dents or displaced flashing

Cleaning Methods

Low-pressure rinse (below 500 psi) combined with pH-neutral detergent removes pollen and soot
Soft bristle brush for stubborn debris; avoid abrasive pads that can scuff coatings

Minor Repair Protocol

Dab of color-matched touch-up paint seals scratches smaller than a nickel
Replacement of individual fasteners tightened beyond design torque to prevent panel oil-canning

Snow Management

Snow guards installed above entrances and walkways reduce avalanche risk
Lightweight roof rakes with rubber blades clear excessive snow loads without scratching paint

Common Signs a Roof Needs Replacement

Visual Cues

Uneven decking surfaces telegraphing through existing asphalt layers
Granule loss forming bald patches in current shingle roof systems
Rust streaks or red oxide film on exposed metal flashings

Performance Symptoms

Attic moisture accumulation indicated by rusty nails or mold on rafters
Persistent hot spots in living spaces despite ventilation upgrades
Granulated debris appearing in gutters after each rainfall event

Structural Indicators

Sagging ridge lines suggest compromised trusses or decking rot
Daylight visible through roof boards at penetrations or seams
Soft spots underfoot during roof walk indicating spongy substrate

Metal Roofing Myths Debunked

Noise Levels

Modern assemblies incorporate high-density underlayment and attic insulation, reducing rain noise to levels comparable with architectural shingles.

Lightning Concerns

Metal roofing does not attract lightning; it safely dissipates the electrical charge across the surface and into the ground with proper grounding systems.

Temperature Fluctuation Misconceptions

Metal quickly sheds absorbed heat once the sun sets, preventing prolonged radiant transfer into living spaces.

Weight Misconceptions

Steel and aluminum panels often weigh less than half of a traditional asphalt roof, decreasing structural load and sometimes enabling installation over existing layers when code permits.
