Answers to Common Questions
View All FAQsHow much does it cost to replace a shingle roof per 1000 sq ft?
KTM Exteriors & Roofing does not publish a fixed per‑1,000‑sq‑ft shingle roof price; we confirm pricing after an on‑site inspection of your home. The biggest swing in cost usually comes from material choice and whether the old roof needs full tear‑off before installation.
For clarity, roofers price by “squares” (100 sq ft), so 1,000 sq ft is about 10 squares. We regularly replace roofs in the Newfields area and match the system to your roof’s design and local weather.
- Key cost drivers we assess on site:
- Shingle type (traditional asphalt vs. composite options)
- Roof pitch and complexity (valleys, dormers, skylights)
- Tear‑off needs and disposal of old materials
- Decking or flashing repairs discovered after removal
- Ventilation upgrades to protect the new system
If you’re deciding between repair and full replacement, base it on remaining shingle life and the condition of the roof deck after tear‑off photos are reviewed together. <br/> Updated: 2026-06-04 <br/> Need help in Newfields, NH?
