 Another project in South Saint Louis City, this garage was to follow the theme of the surrounding buildings while incorporating modern convenience and a roof structure capable of supporting a future deck. Project completed in June of 2007.
As you browse through the images of this project there are some items of interest. First, instead of using aluminum cap-flashing to cover the tops of the parapet walls, we chose to use new clay coping tiles that matched the original ones on the house in size and shape. Second, you may notice the black roofing material overhanging the door end of the garage in the pictures taken prior to the installation of gutters. This material is a 60mil rubber made by Firestone Corporation and it bears a 20 year warranty while supporting eco-roofing options and deck overlays. It is also only 1 layer thick so future removal produces significantly less waste. Third, the building had to serve primarily as a garage, but also as a rooftop deck.
The framing of a structure like this is its own form of art. Designed to have no posts or support columns in the garage interior, the idea of supporting a rooftop deck seemed tricky at best. One of the main issues in a project like this is often affordability (anything is possible with an unlimited budget) and staying within the budget. To achieve this end, 2x6's were used to frame the perimeter walls and they run continuous to form the parapets. Then, double TrussJoist rim boards were pocket-cut in dadoed channels into the 2x6's. Finally, 14" TJI ceiling joists were installed with top-flanged joist hangers. Over the door a 3x12 LSL beam was used. The roof deck had been laid out at a 3-degree pitch and was decked with 3/4" Advantech tongue & groove subfloor and secured wth ring-shank nails and all-weather adhesive. The result? It is plenty strong.
Hardie Cedarmill Cement Siding (6.25") installed over Tyvek satisfies both the historic requirements and the building requirements for the region. It also looks good and requires very little maintenence. The corners and sill boards are Miratec 25yr warranty cedar grained composite. It is hard to tell the difference between it and natural lumber even when they are placed side by side.
The roofing tiles are made of a fired clay. The only safe and accurate way to cut them on site is using an abrasive or grinding blade. This makes for a uniform and professional finsihed product, but a dusty job.
Oh, I almost forgot. This is where we started...
