Roof Inspections and Leak Diagnosis

Leaks often start in places you can’t see from the ground. We inspect the attic for moisture staining, rafter condition, and decking integrity, then check flashing at chimneys, vents, and valleys. Inspections happen on the roof and in the attic because aerial estimates routinely miss rot and hidden mold.

Roof Repair and Storm Damage Restoration

Wind and hail often damage a small area of roofing without requiring a full replacement. We replace damaged shingles or tiles, reinforce valleys and flashing, and address ice dam problems at the source, which is usually attic heat loss and ventilation.

Steep-Slope Roof Replacement

Replacement begins with a full tear-off down to the deck, followed by deck repair where needed. We install GAF Timberline HDZ and Owens Corning Duration shingles over synthetic underlayment, with self-adhering ice-and-water barrier along eaves, valleys, and penetrations.

Low-Slope and Flat Roof Systems

Flat roofs and low-slope additions use modified bitumen, EPDM single-ply membrane, and Mule-Hide or Carlisle products. Where a flat section meets a steep roof, we tie the membrane into the shingle assembly with custom counter-flashing so water sheds away from the joint.

Repair or Replacement: How to Decide

A repair fixes a specific failure. A replacement is warranted when failures are widespread or the roof structure is compromised. The table below shows the most common distinctions.

Condition	Usually a Repair	Usually a Replacement
Shingles	A few cracked or wind-lifted shingles	Curling and granule loss across most slopes
Flashing	One cracked pipe boot or lifted flashing	Corroded flashing at several roof planes
Decking	An isolated soft spot	Rot spread across a large area
Leaks	One leak with a clear, local cause	Repeated leaks from different locations
Roof age	Sound roof with an isolated problem	Repairs no longer keep up with new failures

Roof age alone does not determine the answer. An inspection that includes the attic shows whether a problem is isolated or systemic.

Roofing Materials and Installation Components

A shingle roof performs only as well as the layers beneath it. Our assemblies use synthetic underlayment, self-adhering ice-and-water barrier at vulnerable edges, and custom-formed metal flashing at every penetration. Attic ventilation balances soffit intake with ridge exhaust, which keeps the deck cold in winter and limits heat buildup in summer. Gutters discharge away from the foundation to finish the system.

Roofing Permits and Municipal Compliance in Downers Grove

Royal Craft prepares technical specifications, submits permit applications through the Village of Downers Grove online portal, and coordinates the code checks and municipal inspections that follow. Property owners remain responsible for the permit, and the contractor handles the submission on their behalf. Confirm current requirements with the Village before work begins, since local amendments can change the scope of a permit.

Pricing, Warranties, and Consumer Protections

Final pricing depends on roof pitch, the number of existing layers, decking condition, and the material class you choose. The written proposal itemizes labor, materials, ventilation work, and fixed costs so you can compare it directly with other bids.

Royal Craft backs labor with a 10-year workmanship warranty covering installation, flashing details, joint seals, and weatherproofing interfaces. Manufacturer system warranties are registered at project completion and transfer to later owners when you sell the home. Financing is available through GreenSky. Financed and cash customers pay the same price, and the homeowner approves each milestone draw before funds are released.

Frequently Asked Questions About Roofing in Downers Grove

Does a roof replacement in Downers Grove require a Village permit?

Most residential re-roofing projects require a permit from the Village of Downers Grove. Royal Craft submits the application through the Village portal and schedules the required inspections.

How do I know if ice dams are causing my roof leak?

Ice dams usually cause leaks near exterior walls, with staining on ceilings or walls and icicles hanging from the eaves. Heat escaping from the attic melts snow on the roof, and the water refreezes at the cold eave edge. Attic insulation, air sealing, and balanced ventilation reduce this heat loss and address the cause.

What is the advantage of an owner-supervised roofing project?

A principal on site makes decisions when unexpected conditions appear, such as rotted decking under the old shingles. You get direct answers and a single point of accountability from start to finish.

Can you tie a flat roof addition into an existing steep shingle roof?

Yes. The low-slope membrane is terminated under custom counter-flashing at the wall, and the shingle courses are integrated with the transition so water flows away from the joint. This prevents the joint leaks that often develop where two roof types meet.

How long does a typical residential roof replacement take?

Duration depends on roof size, the number of layers being removed, weather, and the deck repairs needed. The written proposal includes a schedule based on your specific roof.

How do I verify an Illinois roofing contractor’s license?

Use the online license lookup from the Illinois Department of Financial and Professional Regulation. Royal Craft’s Illinois roofing contractor license number is #104.012213, and it is listed on every proposal.
