Manufacturer vs. workmanship coverage explained.
April 17, 2026 • Houston Roofing
Roof warranties sound simple but contain critical fine print. Understanding what your warranty actually covers — and what voids it — can save you thousands of dollars if something goes wrong in the next 20 years.
Manufacturer warranty. Issued by the company that made the shingles, metal, tile, or membrane. Covers defects in the material itself — premature granule loss, delamination, color fading, structural failure. Length ranges from 25 years to "lifetime" depending on product line.
Workmanship warranty. Issued by the contractor who installed the roof. Covers installation errors — improper flashing, wrong nailing patterns, leaks due to installer mistakes. Typically 5-10 years. Houston Roofing provides a 10-year workmanship warranty on every residential installation.

Both types of warranty exclude:
"Lifetime" usually means "for as long as you own the home" — not forever. Many shingle warranties are also pro-rated, meaning coverage decreases over time. A "50-year lifetime" warranty at year 30 might reimburse only 40% of replacement cost. Read the fine print and ask the installer to explain pro-ration terms before signing the contract.
Can the warranty transfer to the next homeowner if you sell the house? Some warranties transfer once for a small administrative fee. Others are non-transferable. Transferable warranties add meaningful resale value — typically a few thousand dollars — so this matters. Many manufacturer warranties also require the transfer paperwork to be filed within a short window after sale.
Common warranty-voiding actions:
Manufacturer-certified installers (like Houston Roofing) can offer extended warranties unavailable to non-certified roofers — sometimes upgrading a standard 25-year warranty to a 50-year system warranty covering both material and labor. These require specific installation practices and inspection. The upgrade usually adds a few hundred dollars to project cost and substantially increases protection.
After any roof replacement, you should receive: the written manufacturer warranty certificate (we handle the registration on your behalf), the written workmanship warranty from your installer, and a paid final invoice. Keep these documents permanently — they are essential for future claims, insurance discussions, and home resale.
