Cost, timing and what to ask
The 8 questions that actually decide roof repair, answered with estimated ranges.
Note 01What to do if you have roof damage from a storm?
Make it safe, catch any water, and read the ground. Keep clear of anything hanging and of wet ceilings near light fixtures, put a bucket under any drip, then look at the foot of each downspout for shingle granules and along the gutters and fascia for dents. Photograph all of it. Then call: water coming in is cover today; a dry ceiling with some grit at a downspout is a repair to book for a dry day.
Note 02How urgent is roof repair?
It depends on what water is doing. Water coming in now, near anything electrical, or getting worse with each rain is urgent. Shingles torn off with the underlayment showing should be dealt with before the next storm. A cracked shingle with a dry ceiling, or a little grit at one downspout, can wait for a booking. Every visit ends with that answer in writing.
Note 03What is the average cost to repair a roof in Texas?
No Texas-wide figure turned up in what we checked, so the honest answer uses national ones: most roof repairs are estimated at $300 to $3,000, averaging around $900 in 2026. For Sherman specifically, one storm-repair listing puts small repairs at $300 to $1,000 and moderate ones at $1,000 to $5,000. Your figure follows what the roof needs once it has been seen.
Note 04Is a 10 year old roof considered old?
In North Texas it can be. A Sherman roofer says roofs between 10 and 15 years old are worth having looked at, and puts their useful life here at about 10 to 12 years, because of the heat, the cold and the severe weather. National figures rate asphalt shingles at 15 to 30 years. So ten years is a reason to look, especially after hail, not a verdict on its own.
Note 05How long can you leave a leaking roof?
A small, steady drip in one spot, caught in a bucket, can usually wait a few days for a proper repair. Water near a light fixture, a ceiling that bulges, or a leak that grows with each rain cannot wait at all. The longer any leak runs, the more decking, insulation and ceiling it takes with it, and a soaked deck is how a sag starts.
Note 06What is the cheapest way to repair a roof?
Fix what actually failed, once, as early as possible. After a storm that means repairing the slopes the hail or wind really hit, with shingles woven in and flashings renewed, rather than sealant over the top that has to be redone next season. Reading the downspouts and gutters first keeps the repair to the slopes that need it.
Note 07What to look for when choosing a roofing contractor?
Someone who looks before pricing, writes down what they found, and separates storm damage from ordinary age. In Sherman, ask to see the contractor's City registration: the City requires roofing contractors to register and file a $300,000 liability certificate. Texas issues no state roofing license, so that registration is the credential to ask for. And get the scope and price on a written quote.
Note 08Do you need a permit to get your roof redone?
In Sherman, yes. The City requires a roofing permit for the reconstruction of any residential or commercial roof. The fee is $75, and a contractor who starts without one is charged a $250 fee. Permits go through the City's Self Service Portal, and whoever does the work normally pulls it. For a smaller repair, ask the City if you are unsure whether it counts.
