The difference between a roofing project that lasts and one that becomes a callback is almost always in the details that don't show up in a low bid.
These are the specs and design decisions our team insists on for every Houston home — the ones that quietly separate a real professional install from a cheap one.
1. Full tear-off, not overlay
Layering shingles adds weight, traps heat, and hides deck damage. Full tear-off is the honest install.
2. Deck inspection and rotten sheathing replacement
Every rotten piece of decking gets replaced during tear-off. Roofing over rot is a callback waiting to happen.
3. Ice-and-water shield at eaves and valleys
Even in Houston, a peel-and-stick membrane at eaves, valleys, and penetrations prevents leaks.
4. Synthetic underlayment, not felt
Synthetic underlayments outlast felt 3-to-1 and dont tear on the crew.
5. Ridge and soffit ventilation balanced
Under-ventilated attics cook shingles and grow mold. Balanced intake and exhaust is required for warranty.
6. Proper flashing at every penetration
Step flashing, kick-out flashing, and chimney flashing done right — 90% of leaks start at bad flashing.
7. Impact-rated shingles for insurance discount
Class 4 impact-rated shingles cut insurance premiums 15–30% in Houston and last longer.
8. Drip edge on all edges
Metal drip edge protects the fascia and directs water into the gutter. Non-negotiable.
9. Ridge cap shingles, not cut 3-tabs
Purpose-made ridge caps last as long as the field shingles. Cut 3-tabs fail in half the time.
10. Manufacturer system warranty
Registering a full-system install with the manufacturer unlocks 25–50 year warranties, not the standard limited one.
The bottom line
Any of these can be skipped to hit a lower price — and every one of them will show up as a problem within a few years. Ask any contractor bidding your roofing project which of these are included, in writing. The honest ones welcome the question.
If you'd like to walk through what these look like on your specific home, our team is happy to do a no-pressure consultation.
