South Beloit Homes and Their Roofs
South Beloit has two kinds of housing, and they wear out their roofs differently. Near the Rock River and the older blocks downtown, many houses were built before the city incorporated in 1917. Builders here used the buff limestone that runs along the Rock River and Turtle Creek, and some of those houses still sit on limestone basement walls well over a foot thick. Above those old walls, the roofs have usually been replaced several times. Expect steep pitches, brick chimneys, closed valleys and, now and then, a layer of shingles nailed over an older one.
Then there is the growth era. The Census counted 5,397 people in South Beloit in 2000 and 7,892 in 2010, and Census estimates put nearly half of the city’s homes in the 1990 to 2009 range. Those newer subdivisions are mostly on the builder’s first shingles. At 15 to 25 years old, those roofs show curled tabs, bare granule patches and cracked pipe boots, which are the usual signs a replacement is close.
What Goes Into a Martin Roof
- Full tear off. We strip the old shingles down to the deck so we can see the wood.
- Deck repairs. Soft or rotted boards are replaced before anything new goes on.
- Ice and water shield on every eave. Plus around chimneys, in valleys and at other spots where water collects.
- A complete GAF roof system. Underlayment, starter strips, shingles and ridge caps that are made to work together.
- Balanced ventilation. Intake and exhaust sized to the attic. See attic ventilation.
- New flashing. We replace flashing instead of reusing old metal.
- Cleanup. Magnet sweeps for nails and a hauled away dumpster at the end of the job.
One Office for Both Sides of the State Line
South Beloit runs right into Beloit, Wisconsin, and plenty of families here have a parent or a rental across the line. We work on both sides from the same Roscoe office and the same phone number, so one call covers a roof in South Beloit and one in Beloit. The Illinois roof gets the same system and the same warranty options as the Wisconsin one.
How Replacement Day Goes
Most South Beloit roofs are done in a day. We arrive in the morning, protect the yard and landscaping, tear off and inspect the deck, then install the new roof and clean up before we leave. A steep older house or one with several layers can take longer, and weather can move the start date. We do year round installs, so a roof that needs to come off in late fall or winter does not have to wait for spring.
Shingle Choices
We lead with GAF. The Timberline line covers most homes, with plenty of colors to match brick or siding. If you want more protection from hail, ask about Class 4 impact resistant shingles. Metal roofing is available on request; see metal roofing. Martin is also a CertainTeed SELECT ShingleMaster, so we can match a CertainTeed roof when that is what a house calls for.
Warranty and Paying for It
As a GAF Master Elite contractor, we can offer a 50-year GAF warranty with up to 30 years on workmanship (GAF eligibility rules apply). Our GAF warranty page explains what it covers. Financing is available as low as $149/month for qualified buyers; see financing options. For a sense of overall cost, read our roof replacement cost guide.

South Beloit Roof Replacement FAQ
How long does a roof replacement take on a South Beloit home?
Most roofs are done in a day. A steep older house or one with more than one layer of shingles can take longer, and weather can move the start date.
What do you find under the old shingles on older South Beloit houses?
Often a second layer of shingles, plank decking with gaps, and some soft boards near the eaves or chimney. We replace bad decking before the new roof goes on.
Do you replace rotted decking during the job?
Yes. We tear off to the deck on every job, and any soft or rotted boards are replaced before the new roof goes on.
Will a new roof fix the ice buildup along my eaves?
It helps. Every Martin roof gets ice and water shield on every eave, and we balance the attic ventilation so the roof stays colder and ice is less likely to build up.
Can you replace the roof in late fall or winter?
Yes. We do year round installs, so a roof that needs to come off does not have to wait for spring.
