Roof Replacement Services
There are many schools of thought about re-roofing your home and the process that should be used. In many cases re-roofing directly on top of your existing roof can provide substantial savings. These decisions should never be treated lightly, because improper inspection and unseen damage can cause even larger problems later and cost even more in the long run.
We at Lujan construction can inspect your roof and determine if your roof needs to be torn off and then re-roofed or if your roof is structurally sound enough to re-roof directly on your existing shingles.
The same cost savings and structural rules apply to retro-fit metal roofing when installed over an existing asphalt roof. Again the most important part is determining the soundness of the existing roof.

Asphalt shingles are by far the most common roofing material used for residential roofing applications. They are easy to install, relatively affordable, last 20 to 50 years and are recyclable in some areas. Asphalt shingles come in a large number of styles and colors.
The protective nature of paper and fiberglass asphalt shingles primarily comes from the long-chain petroleum hydrocarbons, while wood shingles are protected by natural oils in the cellulose structure. Over time in the hot sun, these oils soften and when rain falls the oils are gradually washed out of the shingles. During rain, more water is channeled along eaves and complex rooflines, and these are subsequently more prone to erosion than other areas.
Two basic types of wood shingles are called shingles and shakes. The difference is in how they are made, the shingles are sawn and shakes are split. Wood shingles and shakes have long been known as a fire hazard and have been banned in various places, particularly in urban areas where exterior, combustible building materials contribute to devastating fires known as conflagrations.
Slate shingles are also called slate tiles. Slate roof shingles are relatively expensive to install but can last 80 to 400 years depending on the quality of the slate used. An important aspect to slate roofs is the use of a metal flashing which will last as long as the slates. Slate shingles may be cut in a variety of decorative patterns and are available in several colors. Flagstone shingles are a traditional roofing material. Some stone shingles are fastened in place but some simply are held by gravity so the roof pitch cannot be too steep or the stones will slide off the roof. Sandstone has also been used to make shingles.
Modified bitumen (D67:D81)
Heat-welded, Asphalt-adhered or installed with adhesive. Asphalt is mixed with polymers such as APP or SBS, then applied to fiberglass and/or polyester mat, seams sealed by locally melting the asphalt with heat, hot mopping of asphalt, or adhesive. Lends itself well to most applications.
