Stop Leaks Before the Storm: Preventing Leaks in Rainy Climates

How Rain Penetrates: The Science of Leaks

High winds push rain horizontally, driving water under shingles and through vents. Negative pressure on leeward walls pulls moisture inward. Know your exposure zones, and comment with your region’s wind patterns to compare notes.

How Rain Penetrates: The Science of Leaks

Water climbs against gravity through hairline cracks between materials. Unprimed joints, tight siding laps, and fiber cement seams invite wicking. Share where you’ve seen telltale dark lines; we will troubleshoot capillary pathways together.

Roofing That Resists Rain

Self-adhered membranes around eaves, valleys, and penetrations stop wind-driven leaks when shingles lift. Synthetic underlayments resist tearing during storms. Tell us which products you trust; we’ll aggregate community data into a practical comparison guide.

Roofing That Resists Rain

Most roof leaks begin at intersections—chimneys, skylights, sidewalls, and valleys. Step flashing, counter flashing, and properly lapped shingles create a watercourse. Post photos of tricky details, and we will annotate safe, code-aligned solutions.

Walls, Windows, and Siding That Stay Dry

A ventilated rainscreen—furring strips, drainage mat, or spacer strips—creates an air gap that drains water and promotes drying. Tell us your siding type, and we’ll recommend gap depth and insect screening strategies.

Walls, Windows, and Siding That Stay Dry

Sloped sill pans, flexible flashing, and shingle-style overlaps direct water outward, not into the wall. Share a drawing of your window detail, and we’ll review water paths and fastener placement.

Walls, Windows, and Siding That Stay Dry

Sealant alone fails if joints lack depth control. Backer rod shapes the bead, and movement joints relieve stress. Tell us your climate swings, and we’ll suggest formulas and joint spacing that last.

Gutter Sizing, Guards, and Downspout Strategy

Undersized gutters overflow during cloudbursts, soaking fascia and siding. Use rainfall intensity maps to size correctly, add guards to reduce clogs, and extend downspouts far from foundations. Share your annual rainfall, and we’ll advise.

Grading, Swales, and French Drains

Grade soil to slope away at least six inches in the first ten feet. Swales channel water, while French drains capture subsurface flow. Post a sketch of your lot; the community will iterate improvements.

Rainwater Harvesting Without Backflow Risk

Harvesting reduces storm load, but overflow must bypass foundations. Include first-flush diverters, screened inlets, and air gaps to prevent backflow. Tell us your barrel or cistern setup; we’ll suggest safe overflow routes.

Your Rain-Ready Maintenance Calendar

Seal vulnerable joints, clear gutters, test sump pumps, and stage tarps for emergencies. Photograph roof and wall conditions for comparison later. Tell us your start-of-season routine; we’ll craft a localized prep list.

Your Rain-Ready Maintenance Calendar

Walk the exterior safely from the ground after each intense event. Look for shingle displacement, clogged downspouts, and splashback marks. Share findings or photos, and we’ll help prioritize fixes before the next system arrives.
