Roofing Warranties in Glendale, AZ
Three systems at three prices. The warranty on each one stated plainly, so the choice is yours.
Most roofing estimates in this market bury the single most important decision inside one lump sum. Kellum Roofing does not. Every tile roof proposal we write gives you three underlayment systems at three prices, with the manufacturer warranty on each one stated plainly, so the choice is yours and you can see exactly what the difference costs.
Why the Underlayment Is the Decision That Matters
On an Arizona tile roof, the tile is a shield and the underlayment is the actual waterproofing. Tile can outlast the house. Underlayment cannot, because sustained heat is what ages it. So when you buy a tile roof here, what you are really buying is the underlayment system underneath, and the warranty on that system is the number that tells you what you bought. That is the whole reason we itemize it.

Coverage Distinctions
Understanding the scope of your warranty is critical. Coverage is split into two distinct categories to ensure total system integrity.
Manufacturer Material Warranty
Covers defects in the underlayment and roofing materials themselves. Administered directly by Westlake based on the selected tier. We will give you the actual documentation rather than a summary.
Workmanship Guarantee
Covers the physical installation and application of the materials. Provided by Kellum Roofing. A manufacturer warranty does not protect you from a bad installation. This does. We go over our workmanship terms with you in writing before you sign anything.
System Upgrades
Enhance the performance and efficiency of your roofing system beyond standard waterproofing.
Thermal Sheet Upgrade
A radiant barrier installed during roof replacement. Reflects heat before it transfers into the attic and can lower attic temperatures by up to 31 degrees. Significantly reduces cooling costs through Arizona summers. Available as a priced line item on Good and Better systems, so you decide whether it is worth it for your house.
Maintenance Requirements
Annual Inspections
Have the roof looked at professionally each year, particularly before monsoon season, to catch perimeter breaches, flashing deterioration, or debris accumulation before they become leaks.
Debris Removal
Valleys and gutters must be kept clear of organic debris. Blocked drainage causes water to back up under roofing material rather than run off, which is a common cause of warranty voidance.
Documentation
All maintenance, repairs, and inspections must be documented with receipts from certified professionals to keep the manufacturer warranty valid and enforceable.
