Retrofitting Your Home for Hurricane Protection – part two
Remember that walking on the roof can be dangerous. The shingles could be weak and you could slip. Check for roof failure from the ground. The underlayment and sheathing usually gets blown off along the eaves and rakes which are most exposed to wind damage. Curled and cracked shingles, deteriorated flashing, etc are signs of a roof going bad. You can detect these standing on the ground. You are allowed to place new shingles over the old ones; it saves time. But on the flip side it tremendously increases the load on the roof. It is best that you replace the old tiles with new ones.
It not only reduces the load on the supporting beams and the walls but also offers greater grip and support. While you’re removing the old shingles, you should also remove the underlaying under which the roof sheathing is present. Portions of the sheathing may have rotted away with time; these should be replaced with sheathing of the same thickness. Also check if the roof is fastened with metal hurricane straps. The clips are usually installed at the junction of the roof rafters and the exterior walls.
The roof sheathing should be fastened along the roof corners and eaves; these are spots where the wind pressure intensifies over time. You may wish to use some eight-penny ring shank nails at a distance of four inches, but don’t overdo it or you will split the underlying plywood. For sheathing that is not on the edges, you can have the nails at a distance of around six inches.
You can increase the security of the shingles by adding some quick-setting asphalt cement along the shingle tabs. You need to be particularly careful with shingled roofs as shingles are not really capable of absorbing hurricane force winds. Select shingles that have self-locking tabs. Before laying the shingles ensure that the surface is as level as possible so that the shingles are properly aligned. This will enable shingles with adhesives to fasten nicely to one another.
Additional roofing options include wood shakes, metal shingles, clay and concrete tiles, etc. Clay tiles are the least suitable for use in hurricane-prone regions as they can chip easily and may also become windborne. You will need the advice and inputs of a roofing contractor for these roof-types.

We wanted to self-install so we bought accordions and roll downs from Empire Construction.We measured our window and patio and sent Empire the specs.The shutters were an exact match.Installation is very doable for two reasonably mechanical people. In this case it was only one mechanical person and some extra hands. The accordions were a breeze as installation was mostly marking holes for spots, drilling holes, and screwing them in.Our accordions have locking pins that hold them open and act as a second lock when closed. Even if a projectile breaks the lock the rods will keep the shutters closed.These shutters are Bertha HV1. They are High Velocity Hurricane Zone Approved. Having seen a wide range of shutters we are extremely happy with the quality of the product we received!!

I installed fourteen aluminum accordion shutters which I purchased from Empire Construction.I could not be happier with my choice.The shutters are made very well and are powder-coated.The purchase included all of the required hardware which was powder-coated to match the shutters.The company is very customer-oriented.Michael and his staff were wonderful.They were attentive, helpful, and a delight to work with.The installation video on the website made the installation very easy.I highly recommend Empire Construction to anyone considering a purchase of hurricane shutters. Thanks again. Please say Hi to everyone,
