Roof replacement begins with an inspection and photos, followed by a written scope and price.
For roof replacement in Modesto and 5 towns across Stanislaus, San Joaquin and Merced counties, Roofers Hotline takes one call at (855) 512-1072. The line is answered around the clock, and you get a written estimate before work starts.
Census figures put 55% of homes inside the city limits before 1980, so a replacement estimate is written beside most repair estimates.
The old roof comes off down to the decking, including every extra layer, and the debris is hauled away. The metro's median home was built in 1978, so a second layer is common on houses this age. Ask for the written estimate to see how many layers are on yours. Call to book it.
Once the shingles are off, the boards underneath are checked and any soft or cracked sections are replaced. About 55% of local homes predate 1980, and decades of summer heat age the wood. The estimate notes where decking work is likely. Call to schedule the inspection.
Underlayment and drip edge keep water out at the edges and across the deck. The metro gets about 12 inches of precipitation a year in the 1991 to 2020 normals, mostly in winter, and the 2023 declaration included flooding. Ice-dam risk here is low. The written estimate lists what goes under your roof. Call to ask.
You choose the roofing material, and it is fastened to the manufacturer's rating. With roughly 90 days a year at 90 degrees or higher, ask how each option handles heat. The written estimate prices each choice side by side. Call to compare them.
Step by step, from the first call to the written estimate, the work is explained under how roof replacement works.
More than half of Modesto's homes, 55% by Census estimates for 2019 to 2023, were built before 1980, and the median home dates to 1978. Roofs on houses that age are often on a second or third layer, with decking that has been through many hot summers. Roofers Hotline handles roof replacement here, from the tear-off to the new roof, and every job starts with a written estimate before any work begins. Call 24 hours a day to book the inspection and find out whether your roof needs repair or a full replacement.
Modesto's roofs wear out from heat more than from hail. The nearest NOAA station averages 90 days a year at 90 degrees or higher in the 1991 to 2020 normals, and NOAA's storm records show no hail of one inch or larger in the county since 2015. Long summers bake shingles and dry out the decking underneath, so the visit focuses on granule loss, curling and soft or cracked boards. The written estimate lists what the decking needs before the new roof goes on. Call to schedule the inspection.
For 46 ZIP codes in the metro, roof repair for this metro is one call away, with the visit described step by step.

In a county with 4 tornadoes and 2 damaging wind events in NOAA's storm records since 2015, look first for lifted or missing shingles and for sagging deck lines visible from the street. Heavy granule loss on shingles past 20 to 25 years is the other sign to watch, since hot summers speed it up. Photograph what you see from the ground and do not climb onto the roof. Call, and the inspection will show whether the roof needs replacement or a smaller fix.

Questions
Shingles past 20 to 25 years with widespread granule loss, repairs needed every season on different sections, and a sagging deck line are the main signs. Multiple layers already on the roof point the same way. Call Roofers Hotline for an inspection, and the written estimate will say whether replacement makes sense.
It can. The nearest NOAA station averages 90 days a year at 90 degrees or higher in the 1991 to 2020 normals, and steady heat dries out shingles and decking. Older roofs show it first. Call for an inspection if yours has curling, cracking or bare patches.
Often they do. About 55% of local homes were built before 1980, by Census estimates for 2019 to 2023, so decking may be soft and old layers may be stacked. The written estimate lists decking repairs before work starts. Call to book the inspection.
Yes. California requires roofing contractors to hold a CSLB license, usually the C-39 Roofing classification. You can look up any license at CSLB before work begins. Call Roofers Hotline to book roof replacement here with a written estimate first.
