Two Layers of Protection
Every Crestline roof project includes two types of warranty coverage. Together, they protect your home against defects in the products we use and problems caused by how those products were installed.
Manufacturer material warranty
The shingles, underlayment, and accessories we install carry warranties from their manufacturers — typically covering defects in the product itself, such as premature granule loss or manufacturing flaws. Coverage length and terms depend on the product line you choose. Architectural shingles from major manufacturers often include limited lifetime material warranties with prorated periods; exact terms are listed on your product documentation and spelled out line by line on your quote.
Crestline workmanship warranty
We back our own labor with a workmanship warranty on every roof replacement and repair we complete. This covers installation-related issues — improper nailing, flashing failures at our penetrations, valley workmanship, and similar defects in our work. Specific coverage periods and terms are provided in writing when your project is finished.
What's Typically Covered
- Material defects — manufacturing flaws in shingles, underlayment, or accessories per the manufacturer's warranty terms
- Installation defects — leaks or failures traceable to Crestline's workmanship, such as improperly installed flashing, boots, or valleys
- Repair workmanship — our labor on targeted repairs, including pipe boot replacements, flashing repairs, and leak corrections
- Documentation at closeout — warranty registration paperwork and product information delivered when the job is complete
What's Not Covered
Warranties protect against defects — not every event that can damage a roof. Standard exclusions include:
- Storm and weather damage — new hail, wind, or fallen tree damage is an insurance or out-of-pocket repair, not a warranty claim
- Normal wear and aging — gradual granule loss and cosmetic fading over decades of Georgia sun
- Lack of maintenance — clogged gutters, moss buildup, or deferred minor repairs that lead to larger problems
- Unauthorized modifications — work by another contractor that voids manufacturer or workmanship coverage
- Pre-existing conditions — damage or rot that existed before our work and was not part of the approved scope
- Acts of nature beyond normal weather — floods, earthquakes, and similar events per manufacturer terms
Not sure whether your issue is warranty-related or storm-related? Call us — we'll inspect and give you a straight answer. See our storm damage and insurance support pages if a recent weather event caused the problem.
Keeping Your Warranty Valid
Manufacturer warranties require proper installation per their specifications — correct nail count and placement, approved underlayment, adequate ventilation, and permitted work where required. Crestline installs to these standards on every job. To protect your coverage after installation:
- Keep your warranty paperwork and completion photos in a safe place
- Register your manufacturer warranty if the product requires homeowner registration
- Schedule annual visual inspections — look for lifted shingles, damaged flashing, or debris in valleys
- Clean gutters regularly so water doesn't back up under shingles
- Call Crestline before hiring another contractor to modify the roof we installed
