Sentinel fabrications manufacture tiled conservatory roofs using the finest roofing grade timber. All roofs are pre fabricated in pod form on our factory floor then insulated to achieve a 0.18 U'value, we manufacture all pods to 610mm widths (where possible) meaning when a roof gets delivered to site all the pods are simply lifted into place and bolts fitted through the pre drilled holes. A sentinel roof takes on average just 2 hours to install and make water tight.
