Castroville, TX
Shingle, metal and flat roofing for Castroville homes, from the older streets near the Medina River to newer ranch homes on the edge of town. Free estimates and same-day replies.
Castroville is known as the Little Alsace of Texas. Founded by Henri Castro in the 1840s and settled by families from Alsace, it still has steep-roofed historic homes, the Landmark Inn and St. Louis Catholic Church near the Medina River. Around that historic core, newer brick ranch homes and rural properties stretch out along US 90 and the roads into Medina County.
Each of those homes needs a different approach. An older house with a steep pitch and a chimney needs careful tear-off and new flashing, a newer ranch home usually needs a clean shingle replacement with good attic ventilation, and properties with acreage often have barns and shops with metal roofs.
Alanis Roofing is based in Devine, a short drive south. Andres Alanis has 26 years in roofing and 13 years with his own crew, and he gives free estimates, same-day replies and 24/7 emergency help in English or Spanish.
Many older Castroville homes have steep roofs, chimneys and walls that meet the roof at odd angles. Those intersections are where leaks begin, so a good reroof here is as much about flashing as it is about shingles or panels. We replace worn chimney and wall flashing and install new drip edge so water is carried off the roof cleanly.
Castroville has a historic district, and changes to the outside of some buildings may need city review. If your home is in or near the historic area, check with the City of Castroville before choosing a new roof material or color, and we will plan the job around what is allowed.
Castroville sits in the Medina River valley at the edge of the Hill Country, and spring storms can move through quickly with hail, strong wind and short bursts of very heavy rain. Wind lifts shingle edges and loosens ridge caps, and heavy rain finds every cracked pipe boot.
After a strong storm, it is worth having the roof looked at even if you do not see a leak yet. Small damage left alone through a hot summer usually gets worse, and a free inspection tells you whether a repair is enough.
Metal roofing has a long history in rural Texas, and it suits Castroville's mix of old and new homes well. Standing seam panels in colors like terracotta, red, charcoal, bronze or classic silver galvalume can match a traditional home or a modern ranch house.
Metal holds up well to wind, sheds heavy rain fast and reflects more heat than dark shingles. It costs more up front than shingles, so Andres will price both options during the free estimate so you can choose.
