Most homeowners will never step foot on their roof — which means the only way to know if you got a good one is to know what questions to ask before the crew shows up. Here’s what matters.
Type of Shingle
Know where the material is being ordered from. “Seconds” are when a distributor mixes batch numbers, creating pattern and color inconsistencies across your roof. When evaluating a shingle, ask about life span (25-year, 40-year, or lifetime), wind warranty (60 mph up to unlimited), hail rating (Class 3 or Class 4), and the manufacturer warranty.
Starter Shingles
A lot of crews still use a cut 3-tab shingle as a starter course. The problem is it doesn’t seal the edges. Manufacturers now make a purpose-built starter strip with a sealant edge that seals down the perimeter and prevents blow-offs. Make sure starter goes around the entire roof — not just the eaves.
Ridge Cap
It’s extremely common in Tulsa to see a 40-year shingle installed with only a 25-year ridge cap. That’s a mismatch that will cost you. Always ask what ridge cap is being used and make sure it matches the brand and quality of your field shingle.
Ice and Water Shield
Ask which brand your contractor is using. It should be installed in the valleys at minimum — ideally on the eaves as well.
Synthetic Felt
Tar paper is old technology. Synthetic felt is the industry standard now and is a superior product. Always confirm synthetic felt — not tar paper — is going on your roof.
Flashing
Is your contractor replacing the flashing or reusing it? Reused flashing is a leak waiting to happen. If all the metal is being reused, your new roof is already compromised before it’s done.
Ventilation
Is your contractor following the 1/300th rule? This is one of the biggest problems in our industry. We see new roofs go on all the time that don’t address ventilation at all. Proper ventilation protects your attic and makes your shingles last longer.
