Yes, any permanent structure over 200 square feet usually requires a permit and frost footings—temporary pop-up canopies exempt but permanent pavilions with roofs must meet building codes. What requires building permits: (1) Permanent roof structures—covered patios attached to house always require permits (structural attachment). Freestanding pavilions and gazebos over 200 square feet require permits in most Berrien County jurisdictions. Some townships exempt structures under 120-200 square feet—verify with local building department, (2) Foundation requirements—permanent structures require footings below frost line (42 inches in Michigan). Prevents frost heaving and structural damage from freeze-thaw cycles. Building inspector verifies footing depth before concrete pour, (3) Electrical and plumbing—adding electrical outlets or lighting requires electrical permit. Plumbing for outdoor sink or bar requires plumbing permit. Separate permits beyond building permit. What does not require permits: Temporary pop-up canopies with no permanent foundation—must be removable. Portable gazebo kits under 100 square feet in some jurisdictions—verify locally. Note: Even if permit not required, structure still must meet setback requirements from property lines. Permit application process: Submit plans showing structure dimensions, roof design, foundation details. Include site plan showing setbacks from property lines and house. Fees typically $150-400 depending on structure size and jurisdiction. Approval timeline 1-3 weeks in most townships. Inspections required: footing inspection before concrete, framing inspection, final inspection. Zoning considerations: Setbacks: Typically 5-15 feet from side and rear property lines (varies by jurisdiction). Lot coverage: Total impervious surface (house, garage, patios, pavilions) limited to 25-40% of lot area. Height restrictions: Structures typically limited to 15-18 feet height in residential zones. HOA approval: If property in subdivision with covenants, HOA approval may be required beyond building permit. Cost of compliance: Permits: $150-400. Proper footings: $800-3,200 (4-8 footings at $200-400 each). Engineering (if required): $800-1,500 for structures over 400 square feet. Total compliance cost: $1,000-5,000 depending on size and complexity. Consequences of building without permits: Stop-work orders if discovered during construction. Removal orders—may be required to demolish unpermitted structure. Fines: $500-5,000+ depending on jurisdiction and violation severity. Property sale complications—unpermitted structures discovered during title search kill transactions. Buyers demand removal, correction, or price reduction. Insurance denial—claims related to unpermitted structures may be denied. WTS II permit coordination: Determine permit requirements for your specific jurisdiction—41 different building departments in Berrien County. Prepare drawings meeting local standards—engineered if required. Submit applications and coordinate inspections—ensures compliant permanent structure protecting property value.
Yes, we source shingles to match the house for a seamless "always been there" look—proper color and style matching critical for covered patio integration appearing as original architecture rather than afterthought addition. Shingle matching process: (1) Identify existing shingles—determine manufacturer and product line from shingle markings. Common brands: GAF, Owens Corning, CertainTeed, IKO, Tamko. Check attic for leftover shingles from original installation—often labeled with product info. Photograph existing roof in good lighting—color reference for matching, (2) Color matching challenges—shingles fade and weather over time—10-20 year-old roof looks different than new shingles same color. UV exposure lightens colors—sun-facing slopes fade more than shaded areas. Algae growth on north slopes—creates dark streaks not present on new shingles. Regional variations—same product name may have slight color differences in different manufacturing plants, (3) Matching strategies—exact match when possible: If roof recently installed (under 5 years), exact product match looks seamless. Special order same product from manufacturer—may take 2-4 weeks delivery. Close color match when exact unavailable: Select current product closest to faded existing color. Architectural shingles provide more color variation—easier to blend than solid colors. Install sample shingles on roof—view from ground in different lighting before ordering full quantity. Weathering approach when roof old: Accept that new shingles will look slightly different initially—will weather to match over 2-3 years. Alternative: Plan whole-house re-roof coordinating with patio addition—creates perfect match and updates entire roof. Shingle style matching: 3-tab shingles—traditional flat appearance, uniform pattern. Architectural (dimensional) shingles—most common modern style, layered appearance creates depth. Designer shingles—premium shake or slate appearance. Must match style exactly—mixing 3-tab with architectural looks mismatched even if colors similar. Cost implications: Standard colors in stock—no premium cost. Special order colors—$20-40 per square ($200-400 for typical patio) plus 2-4 week lead time. Discontinued products—may require alternative selection if manufacturer no longer makes product. Alternative materials for non-matching aesthetic: Standing seam metal roof on patio—modern accent contrasting with shingle house roof. Creates intentional design statement rather than attempting match. Complements contemporary and farmhouse styles. Cost: $8-12 per square foot installed versus $4-6 for shingles. Cedar shake—premium rustic appearance for timber frame pavilions. Natural material develops silver-gray patina over time. Cost: $10-15 per square foot installed. When matching not critical: Freestanding pavilions away from house—not directly adjacent so exact match less important. Three-season rooms with different roof style—hip roof on patio versus gable on house creates intentional architectural variation. Properties planning near-term re-roof—install current standard shingles on patio, re-roof house to match in 1-2 years.
We install Screen-Tight track systems that eliminate gaps where bugs enter—professional screening installation critical for bug-free outdoor living in Berrien County's mosquito-heavy environment. Why cheap screening fails: (1) Gap infiltration—stapled screens leave tiny gaps at edges where screen meets posts and beams. Mosquitoes squeeze through 1/16-inch openings—gaps invisible to homeowner but highways for insects. Wood trim covering stapled edges compresses screen creating gaps at pressure points. Seasonal expansion and contraction loosens stapled connections—gaps widen over time, (2) Torn screens—staples stress screen at attachment points—tears initiate at staple holes. Dogs and children brushing against screens—tears expand rapidly. Wind flapping—unsupported screen middle vibrates tearing at staples, (3) Door seal failures—cheap screen doors have gaps at threshold—bugs walk under door. Magnetic closures don't seal completely—1/8-inch gap along entire edge. Self-closing mechanisms fail—door left open by kids or guests. WTS II Screen-Tight professional system: (1) Vinyl track installation—continuous vinyl channel screwed to posts, beams, and rafters every 8 inches. Creates rigid frame for screen attachment. Tracks manufactured with internal spline channel—screen rubber gasket presses into channel locking screen. No gaps possible—track completely surrounds screen perimeter, (2) Screen installation process—roll screen across opening overlapping tracks 2 inches. Press rubber spline into track channel using spline roller tool—embeds screen edge creating permanent seal. Excess screen trimmed flush with outside of track—clean finished appearance. Tension screen taut before locking—prevents sagging and wind flapping, (3) Screen options—standard fiberglass 18x16 mesh: Keeps out mosquitoes, gnats, most flies. Most economical—$1-2 per square foot material. Pet-resistant screens: Heavy-duty vinyl-coated polyester seven times stronger than fiberglass. Resists tearing from dogs jumping or scratching. Cost: $2-3 per square foot material. TuffScreen polymer mesh: Nearly impossible to tear—handles severe abuse. Slightly less visibility than fiberglass. Cost: $3-4 per square foot material. BetterVue ultra-fine mesh: Stops no-see-ums and other tiny insects penetrating standard mesh. Nearly invisible—superior view and light transmission. Cost: $4-6 per square foot material, (4) Screen door solutions—commercial-grade aluminum screen door: Heavy-duty frame won't warp or sag. Pneumatic closer ensures positive latching—no gaps. Threshold sweep seals bottom gap—blocks insects crawling under. Cost: $400-600 installed. Retractable screen door: Motorized screen retracts into housing when not needed—disappears completely. Infrared sensor auto-closes after person passes through. No permanent door obstructing opening—preserves view. Cost: $1,200-1,800 per door. Additional bug control measures: Ceiling fans—air movement makes space uncomfortable for mosquitoes, reduces landing attempts. Install 2-3 fans minimum in screened porches. Lighting—use yellow "bug lights" or LED fixtures not attractive to insects. Avoid bright white lights drawing bugs to structure. Standing water elimination—remove water sources around patio within 50 feet where mosquitoes breed. Empty planters, bird baths, gutters regularly. Cost for complete screening: Screen-Tight system: $8-12 per square foot of screen area. 12x20 porch with 8-foot ceiling height: approximately 400 square feet screen area = $3,200-4,800 screening cost. Includes all tracks, screen material, installation labor. Screen doors: $400-1,800 additional depending on style. Total screening system for typical porch: $4,000-7,000—essential investment for bug-free outdoor living May through September in Berrien County.
