What Is A Roof Inspection?

A roof inspection is a professional review of the visible roofing system and related components. The goal is to identify wear, storm damage, moisture entry points, ventilation concerns, and other conditions that may affect performance, then give the homeowner a clear repair, maintenance, or replacement recommendation.

Our Roof Inspection Checklist

Interstate Roofing checks the roof as a complete system rather than looking only at the shingles. A typical inspection includes:

Shingle Condition

We look for missing, cracked, curling, lifted, or heavily worn shingles and signs of granule loss or moss-related deterioration.

Flashing & Seals

Flashing at chimneys, walls, valleys, vents, skylights, and other transitions is checked for gaps, movement, corrosion, or failed sealing.

Flashing at chimneys, walls, valleys, vents, skylights, and other transitions is checked for gaps, movement, corrosion, or failed sealing.

Roof Edges & Drainage

We review gutters, roof edges, valleys, and drainage paths for debris, backed-up water, or conditions that can keep moisture against the roof.

Overall Roof Structure

We look for visible sagging, soft areas, damaged decking indicators, and other conditions that may point to a larger roofing issue.

Why Roof Inspections are Important in Washington

Washington’s long wet season, wind, moss growth, and seasonal debris can turn small roofing defects into recurring moisture problems. Regular inspections help homeowners make decisions before damage spreads.

Catch Small Problems Early
Find worn shingles, loose flashing, and early moisture signs before they become larger repairs.
Check After Severe Weather
Wind, falling debris, heavy rain, and winter conditions can create damage that is not obvious from the ground.
Plan Repair or Replacement
An inspection gives you a clearer basis for deciding whether maintenance, targeted repair, or a larger project makes sense.
Protect Long-Term Roof Performance
Regular inspections help keep drainage, ventilation, roofing materials, and vulnerable details working together.

From the evaluation of the roof condition to the bid proposal, and all the way through to the end result, the entire staff was professional, thorough, and communicated well. The crew was very respectful and efficient, and cleaned up each day before leaving. Even with the adding roof ventilation, the job was still less than our other bid. We had a better shingle selection through Interstate, as well. Thanks for everything!

We had an excellent experience with Interstate roofing. Oscar and Franco did the 2 day job. Oscar was informative and professional, taking pictures of the before and after. They blew off leaves and washed some of the siding for us. Oscar let me know every step and how long it would be and they cleaned up nicely when they were done. They sent out their inspector after the job was completed to make sure everything was done correctly. Very thorough.

Interstate Roofing made, what I thought was going to be a difficult, trying experience, into something that I can only call wonderful. Their quote was very detailed and every question my wife and I had was answered. I have encountered a few roofers and am usually left with doubt and concerns. Not with Mr. Gabel. He ensured that everything was completed properly and went above and beyond to make sure my family was inconvenienced as little as possible. I highly recommend Interstate and Mr. Gabel!!
