Roof Underlayment Replacement Bryan TX is the removal and reinstallation of the water-shedding layer that sits between your roof decking and your shingles or metal panels. That layer is not optional. It is your second line of defense when wind-driven rain pushes past shingle tabs, when ice dams form at the eaves, or when a flashing leak sends water sideways under the surface. We strip the old felt, inspect the decking for rot, and roll out new synthetic underlayment that will not tear or wrinkle in Bryan's summer heat.
Most Bryan homes built before 2005 were roofed with organic felt paper that has a 10 to 15 year lifespan in our climate. After that, it dries, cracks, and stops shedding water. You may not see a leak in the living room yet, but a moisture meter will show damp decking. If you search for Roof Underlayment Replacement near me Bryan TX, you are probably seeing attic condensation, ceiling stains, or a roofing quote that says the underlayment is shot. We handle Roof Underlayment Repair Bryan TX before the damage spreads to rafters and insulation.
Every underlayment replacement includes tear-off of the old felt, a decking inspection, new synthetic underlayment, and reinstallation of your existing shingles where they are still usable. We also seal every penetration and test the work before we leave. Add-ons like new shingles, decking repair, or gutter work are quoted separately so you can see exactly what you are paying for.
We remove the dried, torn, or missing underlayment down to the roof decking. This lets us see the full condition of the wood and find leaks that were hidden under the old felt.
Every section of roof decking gets checked for rot, delamination, and soft spots. We mark damaged areas and replace them with new plywood before installing underlayment, so the new felt has a solid surface.
We install GAF, Owens Corning, or CertainTeed synthetic underlayment, overlapping each course by 4 inches and fastening with a roofing nail gun. Synthetic felt resists tearing and lasts 25 to 30 years in Bryan's climate.
We install ice and water shield at the eaves, valleys, and around chimneys and skylights. This self-adhering membrane seals around nails and protects the most leak-prone areas of your roof from wind-driven rain.
We replace damaged roof flashing and reseal every pipe boot, vent, and chimney with roofing sealant. New flashing and sealant keep water from running under the underlayment at penetrations.
We reinstall your existing shingles where they are still in good shape, or install new asphalt shingles if the old ones are too brittle. We use a chalk line to keep courses straight and replace any cracked or missing shingles.
We walk the roof, check for missing shingles, curling shingles, and flashing leaks, then use a moisture meter and infrared camera inside the attic to find damp decking. You get a written scope with photos the same day. Most inspections take 45 to 60 minutes.
We remove shingles in the work zone with a shingle ripper and pry bar, then pull the old felt. Every section of roof decking gets checked for rot, delamination, and nail pops. Soft spots get marked and replaced with new plywood before we go any further. This step takes 2 to 4 hours on a typical 1,500 square foot roof.
We roll out new synthetic underlayment, overlapping each course by 4 inches and fastening with a roofing nail gun. Valleys and eaves get ice and water shield for extra protection. Every penetration, including roof vents and chimney flashing, gets sealed with roofing sealant and new flashing where needed. This is where the real waterproofing happens.
We reinstall your existing shingles where they are still in good shape, or install new asphalt shingles if the old ones are too brittle to reuse. We use a chalk line to keep courses straight and a caulking gun to seal nail heads and edges. A 1,500 square foot roof takes 4 to 6 hours to shingle back in.
We run a leaf blower over the roof and gutters, then do a water test on the most leak-prone areas. You get a walkthrough, photos of the finished work, and a written warranty on the underlayment. We do not leave until you have seen the work and signed off.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
We use a moisture meter to check decking and insulation for hidden dampness before we install new underlayment. It tells us exactly where the old felt has failed.
An infrared camera shows temperature differences in the attic that reveal wet decking and active leaks. We use it on every inspection to find problems you cannot see with your eyes.
We use a shingle ripper and pry bar to remove old shingles and felt without damaging the decking. This keeps the tear-off clean and lets us reuse shingles where they are still good.
A roofing nail gun drives fasteners at the correct depth and angle, which keeps the underlayment flat and prevents overdriving that tears the felt. We adjust the pressure for each material.
We use a ladder stabilizer and safety harness on every job, especially on steep pitches and two-story homes. OSHA 10 and OSHA 30 training means our crews know how to work safely at height.
A leaf blower clears debris from the roof and gutters before we start, and a caulking gun applies roofing sealant around flashing and penetrations. Clean surfaces make the sealant last longer.
A homeowner in Austin's Colony had a ceiling stain that kept coming back after two roof repairs. The underlayment around the chimney flashing was torn and water was running sideways under the shingles. The decking underneath was soft across a 4-foot section.
We replaced the torn underlayment with synthetic felt, installed new chimney flashing, and replaced the rotted decking. The water test passed the first time. The homeowner saved $2,000 compared to a full roof replacement quote from another company.
A hail storm hit Wheeler Ridge and cracked the underlayment across the back slope of a 15-year-old roof. The shingles looked fine from the ground, but the attic showed moisture on the rafters and insulation. The homeowner had not seen a leak yet.
We documented the hail damage, replaced the underlayment and shingles on the back slope, and installed ice and water shield at the eaves. The insurance claim covered the full repair. The attic dried out within a week.
A 1920s bungalow near Downtown Bryan had original 1-inch decking boards and felt paper that had dried out and cracked. The homeowner was selling the house and the buyer's inspector flagged the underlayment as failing. The roof was 18 years old.
We replaced the underlayment with synthetic felt, replaced 12 feet of rotted decking, and reinstalled the existing shingles. The inspection passed and the sale closed on time. The new underlayment has a 25-year warranty.

“We had a ceiling stain that kept coming back after two roof repairs. Bryan Roof Repair Experts found the underlayment was torn around the chimney flashing. They replaced the felt and flashing in one day and the stain has not returned. They showed me photos of the rotted decking they replaced and the price did not change from the quote.”
Marcus T.Homeowner, Austin's Colony
✓ Verified“Our roof was 18 years old and the felt paper was crumbling. I got three quotes and these guys were the only ones who actually got in the attic with a moisture meter. They replaced the underlayment on the back slope where the hail hit hardest. The job took two days and they cleaned up every nail. My husband checked with a magnet.”
Sandra K.Homeowner, Wheeler Ridge
✓ Verified“I manage six rental houses near Downtown Bryan and use these guys for all my underlayment work. They are fast, they document everything with photos, and they do not try to sell a full roof replacement when a felt replacement will do. Last job was a 1920s bungalow with original decking. They handled it carefully and stayed on budget.”
David R.Property Manager, Downtown Bryan
