How to Read an Exterior Warranty (Before You Sign One)
Warranties are one of the easiest places in this industry to be impressed by the wrong thing. It helps to know that almost every exterior project carries two separate warranties, and they are backed by completely different people.
| Type | Covers | Backed by |
|---|---|---|
| Manufacturer warranty | The product itself — the siding, shingles or window units | The manufacturer. Commonly 20–50 years, and genuinely durable because the company is large and long-established. |
| Installation warranty | How it was installed — flashing, fastening, weather barrier, sealing | The contractor, and only the contractor. It is worth exactly what that company’s continued existence is worth. |
That second row is where most real problems live. The overwhelming majority of exterior failures are not defective product — they are water finding a path through a detail that was installed wrong. So the installation warranty is the one that actually protects you.
Why “lifetime installation warranty” deserves a follow-up question
A lifetime installation warranty is a promise about the contractor’s lifetime, not yours. If a company has been in business eight or twelve years, a lifetime promise is a forecast about a track record that does not exist yet. It is not necessarily dishonest — but it is unverifiable, and it costs nothing to print.
Worth asking any contractor, including us:
- How many years have you been in business under this name and this ownership?
- Is the installation warranty written into the contract, or described verbally?
- What specifically is excluded, and what voids it?
- Who performs the warranty repair — your own crew, or a subcontractor?
- Is it transferable if I sell the house?
Where we stand: Northern Lights Exteriors has been in business since 2001 — about 25 years. We offer a 5-year installation warranty on our workmanship, alongside the manufacturer warranties on the products themselves, which typically run 20 to 50 years. We would rather put a number on it that we have the history to stand behind than print a word that sounds bigger and means less.
