You should inspect your roof at least twice a year, typically in spring and fall. Minnesota's harsh winters and severe storms can cause granule loss, shingle damage, and leaks that worsen quickly if undetected. At O.C. Exteriors & Construction, we recommend professional inspections after major weather events to catch issues early.

TPO is a white, heat-welded membrane that reflects sunlight and offers excellent energy efficiency, while EPDM is a black rubber membrane known for durability and lower cost. Both work well on flat commercial roofs, but TPO typically performs better in hot climates. At O.C. Exteriors & Construction, we help Rochester businesses choose based on building needs and budget.

Replace siding when damage covers more than 30% of the exterior, when you notice widespread rot or warping, or if repairs become frequent and costly. Storm damage, fading, and failing insulation are also signs it's time for full replacement. O.C. Exteriors & Construction assesses the extent of damage to recommend the most cost-effective solution.

Yes, metal roofing performs exceptionally well in Rochester's cold, snowy winters. It sheds snow and ice quickly, resists cracking from freeze-thaw cycles, and can last 50+ years with minimal maintenance. Metal roofs also provide excellent wind resistance during Minnesota storms.

Granule loss occurs due to age, hail impact, foot traffic, or manufacturing defects. As shingles lose protective granules, UV rays accelerate deterioration and reduce waterproofing. At O.C. Exteriors & Construction, our roof inspections identify granule loss early so you can plan for repairs or replacement before leaks develop.

Most residential roof replacements take 1 to 3 days depending on size, complexity, and weather conditions. Commercial reroofing projects may take longer based on square footage and roofing system type. At O.C. Exteriors & Construction, we work efficiently to minimize disruption while ensuring quality installation.

Energy-efficient windows reduce heating and cooling costs by minimizing heat transfer, prevent drafts, and improve indoor comfort year-round. They also reduce condensation, block UV rays that fade furniture, and can increase your home's resale value. In Rochester's climate, quality windows make a noticeable difference on energy bills.

Most municipalities, including Rochester, require building permits for full siding replacement to ensure work meets local codes and safety standards. Minor siding repairs typically don't require permits. At O.C. Exteriors & Construction, we handle permit applications and ensure all work complies with Minnesota building regulations.

A thorough roof inspection includes checking shingles or membrane for damage, assessing flashing and seals, examining gutters and drainage, and looking for leaks or interior water damage. Inspectors also evaluate granule loss, ventilation, and structural integrity. O.C. Exteriors & Construction provides detailed reports with photos and repair or replacement recommendations.

Preparation includes addressing moisture or water issues, checking for foundation cracks, ensuring proper insulation and ventilation, and planning electrical and plumbing layouts. Clearing the space and removing old materials is also essential. At O.C. Exteriors & Construction, we evaluate your basement's condition before transforming it into functional living space.

The biggest mistake is delaying inspection and repairs after a storm. What starts as minor siding or roof damage can quickly lead to water infiltration, mold, and structural issues. At O.C. Exteriors & Construction, we recommend immediate professional assessment after severe weather to document damage and prevent costly complications.

Shingle roofing offers lower upfront cost, easier repair, a wide variety of colors and styles, and quieter performance during rain or hail. It's also the most common roofing material, making future repairs more accessible. At O.C. Exteriors & Construction, we install quality shingle systems that perform reliably in Minnesota's climate.
