Residential and Commercial Roofing Services
This section explains practical options for installing new roofs, choosing replacement materials and scopes, and arranging fast emergency repairs so you can protect property value and occupant safety.
New Roof Installation
When you need a new roof, start with an on-site inspection that records roof pitch, deck condition, ventilation, and flashing details. You should get a written estimate that lists labor, materials (shingles, underlayment, ice-and-water shield), waste removal, and expected timeline.
Choose materials based on climate and building type: asphalt fiberglass shingles for most homes, metal or TPO for commercial low-slope roofs, and slate or tile where aesthetics and longevity matter. Ask about ventilation upgrades and ridge or soffit vents to prevent moisture and heat buildup.
Confirm the crew’s certifications (manufacturers like GAF) and insurance. Schedule work for dry weather and request a final walkthrough to verify flashing, gutters, and clean site removal of old roofing materials.
Roof Replacement Options
You can do a full tear-off or an overlay. A full tear-off removes old roofing down to the deck, lets contractors inspect and repair sheathing, and typically extends service life the longest. An overlay installs new material over existing shingles; it lowers cost and waste but can hide deck problems and shorten warranty periods.
Compare material options by lifespan and cost per square: economy asphalt (15–25 years), architectural shingles (25–40 years), metal (30–60 years), and single-ply membranes (20–35 years for commercial). Get lifecycle cost estimates that include expected maintenance, warranty length, and energy impacts.
Request written warranties for both materials and workmanship, and confirm whether the installer handles permit pulls and disposal.
Emergency Roof Repairs
For leaks or storm damage, secure the area first and prevent further interior damage by tarping holes and diverting water away from openings. Contact a licensed roofer who offers same-day assessments and emergency tarping services. Provide photos and the time of damage for faster triage and insurer documentation.
Emergency fixes should include temporary tarps and priority replacement or flashing repairs if the substrate is compromised. Ask for a clear scope: immediate temporary measures, required follow-up repairs, estimated costs, and timeline. Keep receipts and written estimates to support insurance claims and rapid approval for permanent repairs.
Choosing Professional Roofers
You need contractors who carry proper credentials and who follow a clear, step-by-step project process. Focus on licensure, insurance, manufacturer certifications, written estimates, timelines, and warranty terms.
Certifications and Credentials
Verify the roofer’s state or provincial license number and confirm it matches the company name on file with your local licensing board. Ask for a copy of their general liability and workers’ compensation insurance certificates and call the insurer to confirm coverage and effective dates.
Check for manufacturer certifications (e.g., GAF, Owens Corning) if you want extended product warranties. Request names of recent local jobs and at least three customer references; call them and ask about schedule adherence, cleanup, and any warranty claims. Look for trade association memberships (NRCA, provincial roofing associations) as an extra indicator of ongoing training and code knowledge.
Keep copies of all credentials in your project folder and note expiration dates. If a roofer hesitates to provide docs, treat that as a red flag.
Project Process Overview
Start by requesting a written, itemized estimate that breaks out labor, materials, permits, disposal, and taxes. Confirm the estimate includes start and completion dates, payment schedule, and procedures for change orders and unforeseen repairs.
Ask how the crew will protect landscaping, vents, and skylights, and whether they use plywood or boards for drop zones and tarps for debris containment. Confirm who will pull permits and handle municipal inspections. Get a written warranty covering workmanship and a copy of any manufacturer material warranty; note what actions void each warranty.
Establish a single point of contact and a weekly progress check-in. Before final payment, require a walkthrough and signed completion checklist that documents punch-list items and confirms receipt of lien waivers.
