Homeowner Guide
An honest, research-based guide for Ada County and Canyon County homeowners — covering costs, what to look for, questions to ask, and when to hire a professional.
Missing or curling shingles across large areas, granules accumulating in gutters, sagging roof deck, multiple leaks in different locations, or a roof approaching 20+ years old are all indicators. A single small leak or a few missing shingles in one area may be repairable. Get a professional inspection before deciding.
Asphalt shingles: most common, cost-effective, 20-30 year lifespan. Class 4 impact-resistant shingles reduce hail damage and may qualify for insurance discounts. Metal roofing: highest upfront cost, 40-70 year lifespan, excellent for Idaho temperature swings. Tile: beautiful but heavier — requires structural assessment before installation.
Most roofing warranties have two components: the manufacturer material warranty (covering the shingles themselves, typically 25-50 years) and the contractor workmanship warranty (covering installation quality, typically 2-10 years). Read both before signing. A cheap contractor often means a weak workmanship warranty.
Verify their Idaho contractor license at ibol.idaho.gov before anything else. Confirm they carry liability insurance and workers compensation. Check how long they have been in business locally. Ask for three local references from completed jobs within the past year. Get everything in writing including the scope, materials, timeline, and payment schedule.
After a significant hail or wind event, have a roofer document the damage with photos before contacting your insurance company. Most Idaho homeowner policies cover sudden storm damage but not gradual wear. Your insurer will send an adjuster — having your own contractor present during the adjuster visit is your right and often leads to better claim outcomes.
Most Idaho jurisdictions — Boise, Meridian, Eagle, Nampa, Caldwell — require a building permit for a full roof replacement. Your licensed contractor should pull the permit as part of the project. Work done without a permit may create issues when you sell. If a contractor suggests skipping the permit, consider that a red flag.

Common Questions
Most residential roof replacements in Ada County are completed in one to three days. Larger or more complex roofs may take longer. Weather delays are common during winter months and rainy periods. Your contractor should provide a clear timeline before work begins and communicate any delays promptly.
Idaho homeowner's insurance typically covers sudden storm damage — hail, wind, fallen trees — but not gradual deterioration or wear and tear. After a significant weather event, have a licensed roofer document the damage with photos before contacting your insurer. Most reputable roofers are experienced working with insurance adjusters.
Late spring through early fall is the ideal window — mild temperatures allow proper shingle adhesion and minimize weather delays. Summer is the busiest period for roofers, which may mean longer wait times. Roofing can be done in winter but cold temperatures affect installation quality and some manufacturers require minimum temperature thresholds.
Idaho building codes generally allow one layer of new shingles over an existing layer, but not two new layers over one existing layer. While it saves on tear-off cost upfront, adding a second layer adds weight, can trap heat, and makes future inspections harder. Most roofing professionals recommend full tear-off for best results and longest lifespan.
Verify any roofing contractor's license through the Idaho Division of Building Safety (dbs.idaho.gov) or the Idaho Bureau of Occupational Licenses (ibol.idaho.gov) before signing anything. A valid Idaho contractor license and current liability insurance are the minimum requirements. Ask for the license number and verify it yourself — do not take a contractor's word for it.
Professional roof inspections in the Boise area typically range from $150 to $400 depending on the company, home size, and the detail of the written report provided. Some companies offer free inspections as a sales tool — while convenient, a paid independent inspection gives you an unbiased assessment. Always get a written report.
