Historic metal roof repair in Castroville (78009)

Castroville's Alsatian-style stone houses wear steep, simple roofs, many of them metal. The walls will stand for another century, but the joints where roof meets stone are where water gets in. We repair those details carefully and keep the look that makes the old town recognizable.

Short answer

Leaks in Castroville's older stone homes usually come from the junction between the roof and the masonry, not from the metal panels. Mortar shrinks back, old flashing was often just tucked or caulked, and water runs behind it. We cut a reglet into the mortar joint, install new counterflashing, and repair or replace the metal around it to match.

Where does water get into a stone house?

On a steep roof that butts into a stone gable or chimney, the joint is everything. Many older repairs here used roof cement smeared along the wall, which cracks after a few summers. Water then runs down the stone face, slips behind the metal and reaches the timber framing or the ceiling below.

A proper fix pairs base flashing on the roof with counterflashing set into a cut mortar joint. The counterflashing laps over the base piece, so water sheds outward even as stone and metal move at different rates. It's slow, careful work, and it's the core of our flashing repair on masonry homes.

We also look at the chimney cap and crown, since many leaks blamed on the roof start there. Our chimney leak work covers caps, crowns and the flashing apron around the base.

Can a new metal roof keep the old town look?

Yes, with the right profile. Narrow panels with a low seam, or 5V crimp on simpler cottages, suit the scale of Castroville's older houses. Wide, tall seams and bright paint colors can look out of place next to weathered limestone. We'll bring samples and show you photos of the panel on a similar roof before anything is ordered.

If your home sits in the historic part of town, check with the City of Castroville about exterior review before changing material or color. We can supply drawings, spec sheets and photos for that conversation. Our work on older homes keeps ridge lines, overhangs and trim proportions as they were.

What changes for newer homes outside the old town?

Subdivisions and acreage homes along US-90 and the roads toward Hondo are mostly shingle roofs from the last few decades. They face the same spring hail as San Antonio, and many are nearing replacement. For those, a hail inspection after a storm is the first step, with photos of bruised shingles and dented vents.

Medina County's open ground also lets wind run hard across these homes. We check ridge caps, rake edges and starter rows, where wind lifts shingles first, and fasten new roofs with the full nailing pattern the manufacturer calls for. If you'd like someone to look at either kind of house, phone (210) 750-1898.

Answers

Roofing questions from Castroville

Can you repair just the flashing on my Castroville stone house?

Often, yes. If the metal roof itself is sound, we can rebuild the flashing at the walls and chimney without replacing panels. That means removing the old caulked joint, cutting a clean reglet into the mortar, installing new counterflashing and resealing the panel ends nearby. It costs far less than a reroof and fixes most wall-joint leaks.

Will a metal roof in Castroville be hot in summer?

Metal heats up in the sun, but it also gives off heat quickly once the sun drops. Light colors and bare Galvalume reflect much of the glare. What matters most for the rooms below is attic ventilation and insulation. On older stone homes with little attic space, we look at adding ridge venting where the framing allows it.

Do older Castroville homes have rotten framing under the metal?

Some do, usually near past leaks at walls and chimneys. When we remove panels, we check the purlins or decking and the rafter tails. Small areas of rot can be sistered or replaced during the reroof. We'll photograph anything we find and explain the fix before it changes the price, so you decide with the facts in front of you.
