Should You Repair or Replace Your Roof?

It is indicative, not a verdict. It applies the same criteria a roofer weighs on site: how far the damage spreads, how much life the shingles have left, the leak history, and whether the shingle can still be matched. What it cannot do is test hail bruising by hand or look at your decking, and those routinely change the answer. Treat it as a way to know what questions to ask.

Because a structurally perfect repair can still leave an obvious rectangle on a street-facing slope. If your shingle line is discontinued or the existing roof has weathered well past anything currently produced, the honest options are to accept the patch, reshingle a whole slope so the difference falls at a natural break line, or put the money toward replacement.

No, and that is the most common mistake. Architectural asphalt typically runs 20 to 30 years in North Texas, less where attic ventilation is poor or hail has been repeated. Plenty of twenty year old roofs are sound and plenty of twelve year old roofs are finished. Age is one input.

No. The result shows immediately, and nothing is sent anywhere. The form underneath is there if you want a free inspection to confirm it, which is the only way to be certain.
