Question 1

My Dickinson home was replaced after Harvey in 2018. When will I need to replace it again?

Accepted Answer

Harvey-era replacements in Dickinson used primarily 25-30 year architectural shingles installed in 2017-2020. Those roofs are now 6-9 years into their service life. However, Galveston Bay salt air accelerates metal component corrosion, and many Harvey-era replacements were installed without coastal-grade flashing specifications. Expect the first significant flashing repairs at 8-12 years and first full replacement consideration at 18-22 years — earlier than the stated warranty period if coastal-grade hardware was not originally specified.

Question 2

Why does Galveston Bay salt air matter for a roof replacement in Dickinson?

Accepted Answer

Dickinson is 8 miles north of Galveston Bay. The salt-laden air that bay proximity generates corrodes metal roofing components — step flashing at walls and dormers, drip edge, ridge cap metal, and fasteners — significantly faster than inland Houston locations. A standard inland-spec roof replacement uses aluminum and galvanized steel hardware that begins failing within 5-10 years in Dickinson’s coastal air. Houston Roofing Pros specifies marine-grade stainless and pre-coated metal components for all Dickinson replacements.

Question 3

My Dickinson home was FEMA-elevated on piers after Harvey. What changes for a roof replacement?

Accepted Answer

FEMA-elevated homes present a unique replacement challenge at the junction where the original slab-level wall has been raised on piers. This exposed wall-top junction requires specialized waterproofing membrane and flashing detail that prevents wind-driven rain from infiltrating the open sub-floor space below. Most suburban roofers in Galveston County are not trained in this detail. Houston Roofing Pros specifically addresses FEMA-elevation junction waterproofing on every elevated Dickinson home replacement.

Question 4

Hurricane Alicia (1983) and Hurricane Harvey (2017) both hit Dickinson. Does my roof have layered damage?

Accepted Answer

Dickinson’s dual storm-damage history is unique — Alicia was primarily a wind event, Harvey was primarily a flood event. Homes that survived both may have residual wind damage from Alicia (lifted decking, deteriorated ridge caps) that was then compounded by Harvey. If your home was not fully replaced after Harvey, a thorough inspection may reveal layered damage from both events. Houston Roofing Pros provides comprehensive damage documentation that accounts for the full storm history of each Dickinson property.

Question 5

What roofing materials are best for Dickinson’s Galveston Bay proximity?

Accepted Answer

For full replacements in Dickinson, we recommend architectural shingles with Class 4 impact rating for standard budget, or standing seam metal for best long-term value given the coastal proximity. Architectural shingles should be paired with marine-grade stainless steel fasteners and pre-coated drip edge and step flashing — not standard galvanized. Metal roofing, while the highest upfront cost ($19,000-$21,000), provides the best resistance to both salt air corrosion and direct hurricane wind for Dickinson’s Gulf Coast exposure.

Question 6

Does Dickinson require any special permits for roof replacement given its flood zone status?

Accepted Answer

City of Dickinson and Galveston County building permits are required for roof replacement. For FEMA flood zone AE properties along Dickinson Bayou and its tributaries, an elevation certificate is required for flood insurance compliance. The FEMA 50% substantial improvement rule applies: if replacement cost plus any concurrent renovation exceeds 50% of the structure’s assessed value, mandatory elevation is triggered. Houston Roofing Pros confirms permit requirements and FEMA compliance requirements before starting any Dickinson replacement project.
