Our Roof Installation Process
A new roof is a big investment, and you deserve to know exactly what happens from start to finish. Here is how a roofing installation with Knox’s Construction works.
- Free Inspection and Estimate: We inspect your roof, attic, ventilation, and flashing, then provide a written estimate with no pressure and no hidden costs. You can also get an instant roof quote online.
- Shingle Selection: We help you choose the right CertainTeed shingle style and color for your home and your budget. Browse our shingle designs and colors.
- Property Protection: Before any work begins, we protect landscaping, siding, windows, and driveways with tarps and plywood.
- Tear-Off and Deck Inspection: We remove all old roofing layers down to the wood decking and replace any rotted or damaged sheathing.
- Underlayment and Ice and Water Shield: Ice and water barrier is installed along eaves, valleys, and penetrations, which is essential for Pittsburgh winters, followed by synthetic underlayment across the full deck.
- Shingle Installation and Flashing: Starter strips, shingles, ridge caps, new drip edge, and new flashing around chimneys, vents, and skylights are installed to CertainTeed specifications.
- Ventilation: We confirm your attic has balanced intake and exhaust so heat and moisture do not shorten the life of your new roof.
- Cleanup and Final Walk-Through: We run magnets for nails, haul away all debris, and walk the property with you. We do not leave until you are satisfied.
Most residential roofing installations in the Pittsburgh area are completed in one to two days.

Frequently Asked Questions About Roofing Installation in Pittsburgh
How much does a new roof cost in Pittsburgh, PA?
The cost of a roofing installation in Pittsburgh depends on the size and pitch of your roof, the number of layers being removed, the shingle line you choose, and whether any decking needs replaced. Knox’s Construction provides free written estimates and an instant online quote tool so you know your number before any work starts.
How long does roof installation take?
Most residential roof installations in the Pittsburgh area are completed in a single day. Larger or more complex roofs may take two days. If a job runs past one day, we secure the site and protect exposed areas from the weather each evening.
What is the best time of year to install a roof in Pittsburgh?
Late spring through fall is ideal because shingles seal best in moderate temperatures. That said, we install roofs year-round and adjust our methods for cold weather when needed.
Do you tear off the old roof or install over it?
We recommend a full tear-off. Removing the old roof lets us inspect and repair the decking, install proper ice and water shield, and give you the full manufacturer warranty. Layering over old shingles adds weight and hides problems.
What shingles do you install?
We are a CertainTeed ShingleMaster Premier contractor and install the full CertainTeed line, including Landmark, Landmark Pro, and Landmark Premium, plus designer options like Grand Manor and Presidential Shake.
Is Knox’s Construction licensed and insured?
Yes. We are a Pennsylvania licensed home improvement contractor (PA018587) and carry full liability and workers’ compensation insurance. See our certifications and insurance.
Do you offer financing for a new roof?
Ask us about financing options when you request your estimate. We will walk you through what is available so a new roof fits your budget.
